19-218/T1D-AQ2R2TY/3T 产品概述
一、产品简介
19-218/T1D-AQ2R2TY/3T 为 EVERLIGHT（亿光）出品的 0603 小型贴片 LED，发光色为冷白（COOL WHITE），外覆黄色扩散透镜（diffused yellow lens）。该器件以小体积、高亮度与宽视角为特色，适合在空间受限且需均匀照明的便携与背光类应用中使用。
二、主要电学与光学参数
- 发光颜色：冷白（COOL WHITE）
- 正向电压（Vf）：典型 2.8 V（If = 5 mA）
- 正向电流（If）：推荐 5 mA（建议按应用作适当降额）
- 发光强度：135 mcd（If = 5 mA）
- 发光角度：130°（宽视角，出光均匀）
- 透镜颜色：黄色扩散（改善出光均匀性与视觉舒适度）
在典型工作点（5 mA）下单颗功耗约 14 mW，低功耗特性利于电池供电系统的应用。
三、封装与机械特性
- 封装：0603（亦称 1608 公制）小尺寸贴片，适用于高密度贴片工艺。
- 适配 SMT 贴装、回流焊工艺，支持自动贴片机高速装配。
- 承载较小的热阻，但仍需在 PCB 设计上考虑足够的散热铜箔以保证长期可靠性。
四、应用场景
- 背光与指示照明（仪表、家电、移动设备）
- 仪器面板及键盘背光
- 可见光微照明与状态指示
- 需均匀柔和冷白光的便携设备
五、安装与焊接建议
- 建议遵循 J-STD-020 和制造商的回流焊曲线，峰值温度控制在 ≤ 260°C，回流时间和加热速率按 PCB 和座料实际条件优化。
- 贴装时避免强力挤压透镜表面，防止光学性能退化。
- 建议在设计中为 LED 提供合适限流电阻或恒流驱动，避免过流加速老化。
六、可靠性与注意事项
- 避免长时间在高温高湿环境下存放，使用前按生产商建议进行干燥处理（若为潮湿敏感器件）。
- 在焊接与测试过程中注意静电防护（ESD），并避免超额正向电流或反向电压。
- 若用于高精度色温或显色性要求场合，建议根据样品做光学与色温测量验证。
七、选型建议
该型号以小尺寸、宽视角与较高亮度（135 mcd @5 mA）为卖点，适合需要小功耗且输出均匀的冷白光场合。选型时若追求更高亮度可考虑增大驱动电流并做热管理设计；如需更柔和或色偏控制，应以实物样件确认透镜对色温的影响。
以上为 19-218/T1D-AQ2R2TY/3T 的产品概述。具体电气/光学曲线、封装尺寸与焊接曲线请参照 EVERLIGHT 官方数据手册以获得完整规范与可靠性测试数据。

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.
