# 我的电子实验物料清单

## 封装知识速查：先看外形，再看参数与引脚

**封装是元件的机械外形和焊接接口，不是功能、阻值、容量或额定功率。** `S8050`是型号，`J3Y`是表面丝印，`SOT-23`是封装；`0805 10kΩ 1%`中的0805是尺寸，10kΩ是阻值，1%是精度。

### 1）贴片电阻／电容：0603、0805、1206

下面按商品中常见的**英制编号**解释。前两位和后两位分别近似表示长、宽，单位为0.01英寸；具体公差以器件手册为准。

| 常见英制编号 | 对应公制编号 | 标称长×宽 | 本清单中的位置 |
|---|---|---|---|
| **0603** | **1608** | **1.6×0.8 mm** | **你的电阻封装** |
| 0805 | 2012 | 2.0×1.25 mm | 你的贴片LED封装；电阻尺寸知识对比 |
| **1206** | **3216** | **3.2×1.6 mm** | **你的电容封装** |

注意：“公制0603”可能表示0.6×0.3mm，远小于通常口头说的“英制0603”。购买、选PCB焊盘库时要核对单位体系和实际尺寸，不能只看四位数字。

相同封装可以买到不同阻值／容量。电阻功率并非由尺寸唯一决定；电容还要看耐压、介质、厚度和偏压特性。常见陶瓷贴片电容无极性，但“1206”本身不保证电容无极性，也不保证容量合适。不能将直插电阻的¼W规格直接套到所有0805上。[电阻系列与尺寸资料](https://www.vishay.com/en/product/28705/)

### 2）本批半导体封装

| 封装 | 怎么认 | 本批器件 | 关键点 |
|---|---|---|---|
| **SOT-23** | 常见三端小封装，两脚在一侧、一脚在另一侧 | S8050/J3Y、S8550/2TY、AO3401、SI2300 | 同外形可装NPN、PNP、MOS管等，引脚功能必须逐型号查 |
| **SOD-123** | 两端引脚的小长方体，二极管常有阴极标记 | 用户确认的1N4007 | 按此贴片封装记录，不按轴向直插描述；具体极性标记和额定值看厂家 |
| **SOT-223** | 一边三个小脚，另一边有较大金属片 | AMS1117-3.3 / -5.0 | 金属片通常既导热又导电；不是可随意接地的独立散热器 |

外壳尺寸可帮助辨认：典型SOT-23本体约2.9×1.3mm，SOD-123本体约2.7×1.6mm，SOT-223本体约6.5×3.5mm。**这些是本体尺寸，不是包含引脚的占地尺寸，更不是PCB焊盘尺寸。** 具体变体、引脚间距和推荐焊盘以厂家封装图为准。[SOT-23](https://www.nexperia.com/packages/SOT23.html)、[SOD-123](https://www.nexperia.com/packages/SOD123.html)、[SOT-223](https://www.nexperia.com/packages/SOT223.html)

AMS1117的具体引脚与金属片电气连接应查对应厂家手册；这类器件的金属片常与输出相关，不能凭“散热片”三个字接地。SOT-23也不能仅凭外形把B/C/E和G/D/S互相套用。

### 3）之前提及的直插外形

- **TO-92**：小塑料本体加三根长脚，常有一面较平，适合插入面包板；不同器件／厂家可能有不同脚序。你已确认本批8050、8550为SOT-23，不属于这一项。
- **轴向直插／DO-41类外形**：圆柱本体两端各伸出一根线，普通整流二极管常用；阴极通常由色环标示。你本批1N4007已经确认是SOD-123，不能因为型号常见于直插产品就改写封装。
- **径向直插电解电容**：两根脚从同一端伸出，常见圆柱体。通常有极性，外壳负极标记比剪短后的引脚长度更可靠；这只是此前采购建议涉及的外形，不等于你已经有该元件。

**DIP-8／PDIP-8**：双列直插塑封芯片，通常每侧4脚，端部缺口／定位点帮助识别方向；应按手册顶视图核对1脚。NE555P模块照片中使用这种芯片及插座。它不是SOT-23或SOT-223，也不是8针ESP模块的通用名称。

### 4）外形示意画板

图中覆盖0603／0805／1206、SOT-23、SOD-123、SOT-223、TO-92及轴向直插。左上三件采用相同缩放比例；其余为了看清外形分别放大，**整图不可作为尺寸模板或PCB焊盘图**。图中K为阴极、A为阳极；三端器件不标统一功能脚序，避免误接。

### 5）拿到元件后的核对顺序

1. 看完整型号、厂家和封装，核对物料清单。
2. 打开器件手册，分清顶视图／底视图、引脚编号与实际功能。
3. 确认阻值、容量、耐压、功率／电流等电气参数；不能从尺寸直接推断。
4. 再选择PCB焊盘或转接板：SOT-23、SOD-123、SOT-223分别匹配，电阻0603、电容1206分别匹配。
5. 面包板不能直接插贴片件；先焊转接板和排针，再接线测试。稳压芯片外围电容按对应手册选，不是“焊上任意电容就能稳定”。

### 6）排针、排母／母座：连接板子与杜邦线

**排针是露出的金属针（公端），排母是带插孔的插座（母端）。** “母座”是较宽泛的称呼，不一定就是可与普通排针配对的排母；还可能是其他系列连接器的母端。选购时要看实际外形、尺寸和配套系列。

| 排针／公针 | 塑料条固定的一排或多排金属针 | 焊到开发板、传感器板、贴片转接板，再插杜邦母线或排母 |
| 排母／母座 | 塑料条内是一排或多排金属插孔 | 焊到主板上，让模块可拔插；连接杜邦公线 |
| 直排针／直排母 | 插拔方向通常垂直于PCB | 常见开发板、模块插座 |
| 弯排针／弯排母 | 触点或焊脚转90度，插拔方向通常平行于PCB | 从板边出线，降低整体高度 |
| 长针／加长排母 | 针脚或塑料座高度加长 | 穿过较厚结构、板间叠接；必须核对有效插入长度 |
| 圆孔排母 | 插孔和触点结构与常见方孔排母不同 | 配套圆针连接；不要默认能接所有普通方针 |

**间距（Pitch）是相邻引脚中心到中心的距离，不是针脚宽度。** 常见有2.54mm、2.00mm、1.27mm等。标准免焊面包板通常为2.54mm孔距；本实验选转接连接件时应优先核对2.54mm规格，但不能由此推断每块模块都是同一间距。

- `1×4P / 2.54mm`：单排4位，相邻引脚间距2.54mm。
- `2×5P / 2.54mm`：两排、每排5位，总计10位；还要核对两排之间的中心距。
- `1×40P`：单排40位。排针常可裁成所需针数；普通排母并非都能无损裁切，优先购买所需位数或明确可裁型。
- `直插 / 贴片`：描述连接器怎样焊到PCB；与“公／母”“直／弯”是不同维度。例如可以有贴片弯排母、直插直排针。

配对需要同时满足：**公母类型、间距、排数、针数、针脚截面尺寸、座高和插入深度**。裸排针／排母通常没有防反插结构，插前对齐第1脚与电源方向；同样能插上不等于引脚功能相同。

杜邦线搭配：

| 两端接口 | 常用连接线 |
|---|---|
| 开发板排针 ↔ 模块排针 | 母对母 |
| 开发板排针 ↔ 面包板孔 | 母对公 |
| 面包板孔 ↔ 面包板孔 | 公对公 |
| 排母孔 ↔ 排母孔 | 公对公，前提是针脚尺寸与插入深度匹配 |

本批贴片元件不能直接插面包板，典型连接链是：**贴片元件 → 匹配封装的转接板 → 焊2.54mm排针 → 面包板／杜邦线**。如果希望模块可更换，可在承载板焊对应排母，不要把排针与排母买成不同间距。

排针／排母不是专用大电流电源端子；舵机等负载应按具体连接器额定电流、线径和接触情况选择，不能仅因2.54mm就认定能承受所需电流。

### 7）排线：多根导线并排，不代表接口通用

**排线描述线缆的排列形式，不等于某一种插头。** 常见有杜邦排线、IDC灰排线和彩排线、FFC柔性扁平排线；它们不能仅凭芯数相同就互换。

| 类型 | 外形和连接方式 | 本实验怎样用 |
|---|---|---|
| 杜邦排线 | 多根绝缘导线并排，可有公公、公母、母母端头；常见款可按需要撕分 | 连接STM32、面包板和模块；可把相邻信号线组成一束 |
| IDC灰排线／彩排线 | 多根线平行排列，常配压接式IDC插座和双排盒式排针（简牛） | 适合固定多芯接口；按压接端子和线缆规格配套，不直接当单根杜邦线使用 |
| FFC柔性扁平排线 | 薄片状平行导体，端部裸露接触面，插入配套FFC/FPC连接器 | 常见于屏幕、摄像头等；需要匹配连接器，不能直接插普通排母或面包板 |
| FPC柔性电路 | 柔性基材上的印刷线路，可有分支、焊盘或器件 | 与FFC概念不同；不能仅凭“软排线”称呼判断可替换 |

购买时依次核对：**线缆类型 → 芯数 → 线间距／连接器间距 → 端头型号 → 公母 → 长度 → 线径或厚度 → 第1脚方向**。

- 杜邦线常用2.54mm端头，公母选择与上节一致；多位连体外壳还要核对针位排列。
- 典型2.54mm双排IDC连接器可配1.27mm导线间距的排线：端子间距和线间距是两个参数，不能看到不同数字就判定不匹配，必须按配套规格选。
- IDC排线边缘的色线通常用于标记第1芯，但最终应核对插头第1脚、压接方向及两端接线关系；防呆缺口也不能替代通断核验。
- FFC常见0.5mm、1.0mm间距。除了芯数和间距，还要确认两端接触面是同面还是异面、裸露长度、加强板与厚度。商家“A型／B型”命名不一定统一，以实物图和尺寸为准。
- 排线针位相同不代表电气功能相同。接入前核对VCC、GND、信号顺序，不要按线色直接猜用途。

**当前五路红外最适合用一束杜邦排线整理**：OUT1～OUT5依次到PA1～PA5，按你偏好的方式让信号线排在一侧；VCC与GND可分支到电源位置。是否能用一体七位插头，要先量模块排针间距并确认实际排列。当前接线方案不因此改变。

线缆尽量短，连接牢固；高频摄像头并行信号对线长和回流路径更敏感，换成排线本身不保证消除采集问题。舵机电源应按线径、触点和负载电流单独核对，不要默认细排线适合大电流供电。

### 8）LED与开关：外形尺寸不等于电气参数

- **3mm／5mm圆头LED**：通常指灯体的标称直径，不是两脚间距，也不是波长。红、绿、蓝、白是发光颜色；850nm、365nm是波长，分别记录为近红外和紫外。它们均不表示可直接使用的供电电压。
- **0805贴片LED**：与0805电阻使用同一常见尺寸命名体系，但器件高度、焊盘建议和极性标记仍按实际手册核对。电阻通常无极性，LED有阳极A和阴极K。
- 裸LED一般需要串联限流电阻或恒流驱动。电阻估算为 `R≈(电源电压−LED正向压降−开关压降)/目标电流`，还需核对电阻功率与GPIO驱动能力。不同颜色和红外／紫外器件不能默认共用同一正向压降；规格未确定前不指定统一电阻值。
- 圆头LED未剪脚时常见长脚为阳极、短脚或壳体平边对应阴极，但剪脚、特殊外壳或不同厂家可能改变识别条件。贴片器件标记也不统一，以手册和限流测试为准。
- 850nm红外与365nm紫外的可见亮度不能代表辐射强度，不用直视发射口来判断通电；紫外实验避免照射眼睛与皮肤。先确定电流和实际光功率，再安排测试。[红外发射器及眼安全资料入口](https://www.vishay.com/en/product/83160/)、[365nm紫外器件说明示例](https://www.vishay.com/doc?80182=)；这些链接用于说明原理，不是本批器件的额定参数。
- **本批只有一个贴片开关条目：SMD 6×6mm。** 用户确认四个焊脚是两组复用端子，实际只有两个电气节点，不是四个独立触点；原“四脚贴片开关”已合并。具体哪两个脚内部相连，按手册或断电通断测试确认，不能凭“同一侧”外观猜测。
- 普通瞬时轻触按下接通、松开断开，与自锁开关不同；接STM32时通常需要确定输入上拉／下拉及消抖策略。不能把四脚开关当作任意脚对均可用，也不默认适合直接切换舵机电源。[轻触开关结构说明](https://components.omron.com/us-en/faq/switches/FAQE20058)、[四端轻触开关内部连接示例](https://components.omron.com/sites/components.omron.com.us/files/datasheet_pdf/A204-E1.pdf)。

#### 电阻套装：按用户规格图录入

图片标题：**0603／1%／0R–10M／60种各25只**，标称合计 **1500只**。这是包装规格，不等于已清点的现存数量。用户已确认本批电阻封装为0603。

每格为一种阻值，均标称25只；R表示Ω，k表示千欧，M表示兆欧。

| 阻值① | 阻值② | 阻值③ | 阻值④ |
|---|---|---|---|
| 0Ω | 120Ω | 1.2kΩ | 20kΩ |
| 1Ω | 150Ω | 1.5kΩ | 22kΩ |
| 2.2Ω | 180Ω | 1.8kΩ | 33kΩ |
| 3.3Ω | 200Ω | 2kΩ | 43kΩ |
| 4.7Ω | 220Ω | 2.2kΩ | 47kΩ |
| 5.1Ω | 240Ω | 3kΩ | 51kΩ |
| 10Ω | 270Ω | 3.3kΩ | 75kΩ |
| 15Ω | 300Ω | 4.7kΩ | 100kΩ |
| 22Ω | 330Ω | 5.1kΩ | 200kΩ |
| 33Ω | 470Ω | 5.6kΩ | 300kΩ |
| 47Ω | 510Ω | 7.5kΩ | 390kΩ |
| 51Ω | 560Ω | 10kΩ | 470kΩ |
| 62Ω | 680Ω | 12kΩ | 680kΩ |
| 82Ω | 820Ω | 15kΩ | 1MΩ |
| 100Ω | 1kΩ | 18kΩ | 10MΩ |

图片的1%为套装标题标称；**0Ω是跳线电阻，不按“0±1%Ω”理解**，其最大电阻和允许电流需看具体型号。图片未给额定功率，不能按0603或0805字样直接确定功率。

#### 电容套装：1206／16种各20只

图片包装：YUNYIDA，**1206贴片电容包，16种×20只＝320只**。下表按标签四列顺序逐列转录；每种标称20只。包装未给耐压、容差或介质，不从容量或封装补猜。

| 标签代码 | 换算容量 | 每种标称数量 |
|---|---|---|
| 10P | 10pF | 20只 |
| 22P | 22pF | 20只 |
| 33P | 33pF | 20只 |
| 47P | 47pF | 20只 |
| 220P | 220pF | 20只 |
| 470P | 470pF | 20只 |
| 102 | 1nF | 20只 |
| 222 | 2.2nF | 20只 |
| 103 | 10nF | 20只 |
| 104 | 100nF＝0.1µF | 20只 |
| 474 | 470nF＝0.47µF | 20只 |
| 105 | 1µF | 20只 |
| 225 | 2.2µF | 20只 |
| 475 | 4.7µF | 20只 |
| 106 | 10µF | 20只 |
| 226 | 22µF | 20只 |

读码：标签带P的值按pF直接读；三位数字代码以前两位为有效数、末位为10的指数，单位pF。例如104＝10×10⁴pF＝100nF，226＝22×10⁶pF＝22µF。这里是包装标签代码，不代表每颗贴片电容都有印字。

### D. LED、发射管与开关

状态均为**规格已报**；颜色、波长和本体尺寸不等于供电电压或额定电流。

| 物料 | 确认规格 | 待补尺寸 |
|---|---|---|
| 红色LED | **3mm圆头类** | — |
| 绿色LED | **3mm圆头类** | — |
| 蓝色LED | **3mm圆头类** | — |
| 白色LED | **3mm圆头类** | — |
| 贴片LED | **0805，约2.0×1.25mm** | — |
| 红外发射管 | **850nm，3mm**；机械尺寸采用用户新增3mm参考图，见下方TikZ | 参考图与实物尺寸的一致性、尺寸公差 |
| 紫外发射管 | **365nm，5mm**；用户提供5mm尺寸参考，见下图 | 参考图与实物尺寸的一致性、尺寸公差 |
| 贴片开关 | **SMD 6×6mm，仅一个条目**；四焊脚两组复用，实际两个电气节点；焊盘中心距8×4.5mm，详见尺寸图 | 总高H、按钮直径ØA的具体选型值 |

3mm／5mm按灯体标称直径理解，不能作为脚距。四脚开关的内部连接不按外观猜测，用断电通断测试核对。裸LED需限流；红外／紫外不能靠直视亮度判断功率，避免照射眼睛，紫外也避免照射皮肤。

#### SMD 6×6开关：用户提供的尺寸与PCB焊盘图

单位mm。仍为同一个开关条目，四个焊脚是两组复用端子。

| 项目 | 图中尺寸 |
|---|---|
| 本体平面尺寸 | 6.0×6.0 |
| 本体基座高度 | 3.5；不等于包含按钮的总高H |
| 含侧向端子的总跨度 | 8.0 |
| 同侧端子中心距 | 4.5 |
| PCB焊盘数量及单个尺寸 | 4个，每个1.5×1.0 |
| PCB焊盘中心距 | 横向8.0，纵向4.5 |
| PCB焊盘外缘总跨度 | 横向9.5 |
| 定位柱／推荐定位孔 | 2×Ø1.0定位柱，PCB图为2×Ø1.3孔 |
| 按键行程 | 0.25 |
| 总高与按钮直径 | H、ØA为变量，图中未指定数值 |

PCB图中的两个圆孔是定位孔，不增加电气引脚数；实际有定位柱的版本按图留孔。画板列出端子局部尺寸与安装要点。

#### 发射管机械参数：用户提供的5mm参考图

本图只给出机械尺寸。**5mm图作为本清单5mm／365nm紫外管的尺寸参考，是否与实际购入型号完全一致仍须核对；850nm／3mm红外管不采用这组尺寸。** 365nm、850nm是用户先前确认的波长，不是从这张机械图推得。

| 参数 | 图中数值 | 解释 |
|---|---|---|
| 管体标称直径 | 5.0mm | 不含底缘最大外廓 |
| 底缘最大外廓 | 5.8mm | 顶视图的较大外形尺寸；实际平边按原件 |
| 本体总高 | 8.7mm | 从顶部到底缘下表面，含底缘 |
| 底缘厚度 | 1.0mm | 不等于引脚直径 |
| 两脚中心距 | 2.54mm | 不是总宽或PCB孔径 |
| 短脚伸出长度 | 17mm | 从底缘下表面至短脚末端 |
| 两脚长度差 | 1.5mm | 长脚比短脚多出的长度 |
| 长脚伸出长度 | 约18.5mm | 由17＋1.5计算，非单独实测值 |
| 极性 | 原图长脚A／＋，短脚K／－ | 剪脚或不同型号须重新核对 |

图为可编辑TikZ重绘，保留尺寸关系并简化外形；引脚线宽、平边细节不是加工尺寸。原图未给公差、引脚截面尺寸、建议焊盘、正向压降、额定电流、功率或发射角，因此不从机械外形推断这些参数。

#### 红外发射管机械参数：3mm参考图（替代等比推算）

按用户最新图片的**上半部分3mm规格**记录。“M3”在本条按3mm管体规格理解，不是M3螺纹。此图取代此前“5mm管体等比缩小、引脚不变”的拟定方案；3mm尺寸及脚长均按新参考图独立记录。下半部分5mm图不用于覆盖前面的紫外管参考。

| 参数 | 新参考图数值 | 说明 |
|---|---|---|
| 管体直径 | 3.0mm | 标称尺寸 |
| 底缘最大外廓 | 3.85mm | 不采用比例推算的3.48mm |
| 本体总高 | 5.3mm | 顶部至底缘下表面，包含底缘 |
| 底缘厚度 | 1.0mm | 不采用比例推算的0.6mm |
| 两脚中心距 | 2.54mm | 不等于PCB钻孔直径 |
| 长脚伸出长度 | 18.0mm | 从底缘下表面起算 |
| 短脚伸出长度 | 16.0mm | 从底缘下表面起算 |
| 长短脚差 | 2.0 MIN | 保留原图最小值标记；不是旧图的1.5mm |
| 引脚侧视尺寸 | 0.5 MAX | 侧视对应方向的上限，单位mm |
| 引脚正视尺寸 | 0.7 MAX | 正视对应方向的上限，单位mm；不是圆脚直径 |
| 极性 | 长脚A／＋，短脚K／－ | 按原图；剪脚后另行核对 |

仅转录可辨认的尺寸主值与MAX／MIN标记；细小公差字样不清晰，暂不猜写。850nm来自用户已报物料规格，机械图不提供额定电流、正向压降、辐射功率或发射角。插图简化平边和引脚局部形状，焊盘及钻孔仍需按实际引脚与装配余量设计。

### E. 排针、线缆与端子

本节统一收录连接件。杜邦线在实验中已用，其余按用户已报规格记录。

| 物料 | 规格 | 待补尺寸 |
|---|---|---|
| 排针 | 间距、排数、位数未具体确认 | 间距、针长、针脚截面尺寸 |
| 排母／普通母座 | 间距、排数、位数未具体确认 | 间距、座高、孔径、针脚截面尺寸 |
| 杜邦线／杜邦排线 | 多种连接线已用 | 长度、线径 |
| 细间距排线＋配套母座 | **4P，p=1.0mm** | 线长、厚度、裸露长度、母座外形尺寸 |
| 细间距排线＋配套母座 | **18P，p=1.0mm** | 线长、厚度、裸露长度、母座外形尺寸 |
| 细间距排线＋配套母座 | **22P，p=0.5mm** | 线长、厚度、裸露长度、母座外形尺寸 |
| XH端子／连接器 | **XH，2.54mm间距，2P** | 外形尺寸 |
| XH端子／连接器 | **XH，2.54mm间距，4P** | 外形尺寸 |

细间距排线按FFC/FPC类接口整理，具体系列仍须核实。P是芯数／接点数，p是相邻中心距；首末中心跨度S=(P−1)×p，分别为**3mm、17mm、10.5mm**，不等于排线总宽或母座外宽。两端同面／异面、裸露长度、加强板厚度、母座上／下接触、锁扣与安装方向均需匹配，不能只凭针数选购。

**本批XH连接器按用户最新确认记录为2.54mm间距，含2P与4P。** 首末针中心跨度分别为2.54mm、7.62mm；外壳与安装脚尺寸按配套件图纸。

*尺寸图03：三根铜柱轴向长度按相同比例画出，横向宽度仅为示意；铜母另行放大。M2铜母不标未确认的高度／外径。*

M1／M2是公制螺纹公称规格，不是可用卡尺直接测得的螺纹孔光孔直径。铜柱“前数＋后数”为柱体长度＋伸出外螺纹长度；支撑板间距通常主要看柱体，不直接用总长。需另核对六角对边、对角、内孔深度、牙距和啮合长度。

参考商品图的铜母M1.0×1.5×2按“螺纹／高／外径”说明，但**本批M1x3-4以用户纠正的外径3、高4为准**。图中M3铜柱的0.5mm牙距、4.6mm对边、5.2mm对角不套到本批M1／M2。滚花铜母的安装方式须匹配材料，不默认一律热熔。

金属安装件会导电，核对孔周焊盘和邻近走线；盲孔避免螺栓顶底却未夹紧。现有板孔与这批五金是否匹配尚未实测。
