XL-302UYD（F3 黄）直插发光二极管 产品概述
一、产品简介
XL-302UYD 是成兴光（Xinglight）推出的一款直插式 3mm 黄光发光二极管。灯头为圆形（D=3mm）、黄色透镜，外观统一、光色稳定，短脚设计便于快速装配与识别。典型用途为面板指示、仪表显示、按键照明等需要小体积、高亮度黄色指示的场合。
二、主要参数
- 发光颜色：黄色（黄色透镜）
- 波长范围：585nm ~ 595nm，峰值波长 588nm
- 发光强度：1500 mcd（典型值）
- 发光角度：30°（定向度高）
- 正向电流（If）：20 mA（最大/额定）
- 正向压降（Vf）：2.2 V（典型）
- 功率耗散：50 mW（最大）
- 工作温度：-20 ℃ ~ +85 ℃
- 封装：插件（直插），3mm 圆头，短脚（短脚为负极）
- 品牌：Xinglight（成兴光）
- 型号：XL-302UYD
三、光学与电气特性解析
该灯具备较窄的30°发光角，光束集中、指向性强，适合作为精确指示信号源。典型发光强度 1500 mcd 在 20 mA 驱动下可保证良好可视性。按 Vf=2.2 V、If=20 mA 计算，器件耗散功率约 44 mW（2.2V×0.02A），仍低于 50 mW 的额定功率，但建议在实际电路中留有余量以保证长期可靠性。
驱动实例（参考）：若使用 5V 电源，限流电阻 R = (5V − 2.2V) / 20mA ≈ 140 Ω（取标准值 150 Ω），功率 P_R ≈ (2.8V × 0.02A) = 0.056W，选择 1/4W 或更高功率电阻。
四、使用与安装建议
- 极性识别：短脚为负极（负极/阴极），长脚或扁平边为正极。
- 焊接建议：避免长时间高温，手工焊接建议尽量缩短加热时间；焊后允许片刻冷却再弯脚。若使用波峰或回流工艺，请确认整体工艺温度曲线与元件耐温匹配。
- 热管理：工作环境高温时应降低驱动电流或增加间隔散热，长期在高温极限（+85 ℃）下工作可能加速寿命衰减。
- 防静电：尽管普通 LED 对 ESD 敏感度低于某些半导体，但在装配和搬运时仍建议采取基本静电防护措施。
五、适用场景与注意事项
适用于家用电器指示灯、仪器仪表、控制面板、电子玩具、装饰或标识照明等。由于工作温度下限为 −20 ℃，若产品需在更低温环境（例如部分汽车前端或极寒地区）使用，应选择适配级别更高的器件。注意在高亮度长时间点亮或串联多颗 LED 时需合理设计限流与散热。
六、包装与品牌信息
XL-302UYD 以插件封装供货，便于手工或自动插件装配。成兴光（Xinglight）为元器件品牌，提供稳定的批次一致性与出厂电性能测试。订购时请确认批次与质量证明（如有特殊配色或光通量需求，可与供应商沟通定制或筛选）。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
