EVERLIGHT 17-21/T1D-CP2R1TY/4T — 0805 贴片白光LED 产品概述
一、产品简介
Everlight（台湾亿光）型号 17-21/T1D-CP2R1TY/4T 为 0805 封装的贴片发光二极管，单独二极管设计，发光颜色为白色，采用雾状黄色透镜以改善光色混合与外观均匀性。器件针对小型指示与背光应用优化，在紧凑空间内能提供宽视角、稳定的发光表现。
二、主要电光参数
- 发光颜色：白色
- 正向电压 Vf：2.6 V ~ 3.0 V（典型工作点随电流、温度略有变化）
- 额定正向电流 If：10 mA（推荐驱动）
- 最大功率耗散：40 mW（器件热限制，请勿长期超额运行）
- 发光强度：57 mcd ~ 140 mcd（按分档/波动范围）
- 发光角度：150°（大视角，视觉覆盖广）
- 工作温度范围：-40 ℃ ~ +85 ℃
三、封装与光学特征
该器件采用 0805 SMD 封装，体积小巧便于高密度 PCB 排布。雾状黄色透镜设计有助于：
- 提高白光的色彩混合均匀度，减小点光源感；
- 降低炫目，改善视觉舒适度；
- 保持宽达 150° 的出光角以覆盖更大视野。
独立二极管配置便于单点指示与分区背光控制。
四、热管理与可靠性
器件额定最大功率 40 mW，应通过限流或恒流驱动在推荐 If 范围内工作以保证寿命。工作温度范围 -40 ℃ 至 +85 ℃，可适应多数工业与消费环境。为保证可靠性，PCB 布局应提供良好散热路径并避免长时间在高环境温度和高电流下运行。
五、推荐应用与使用建议
- 典型应用：设备状态指示、面板按键背光、便携消费电子指示灯、工控指示、仪器仪表等。
- 驱动建议：采用恒流源或串联限流电阻，推荐工作电流 10 mA；设计时考虑 Vf 变化与电源裕量。
- 焊接建议：采用无铅回流工艺，遵循制造商回流温度规范（一般遵循 J-STD-020 指南），峰值温度控制以保护器件与透镜。实际焊盘尺寸与焊锡量请参照官方数据手册以确保可靠焊接与热传导。
- ESD/防护：属于静电敏感元件，装卸与贴装过程中需采取防静电措施（佩带防静电手环、使用防静电台垫等）。
六、选型与库存提示
发光强度存在分档（57–140 mcd），请在批量采购时确认所需亮度档位以保证视觉一致性。若对色温或色容差有严格要求，建议与供应商确认色品规范与出厂分档信息。
七、注意事项
- 请勿长期在高于额定功率的条件下使用，以免降低寿命或造成失效；
- 雾状透镜可改善视觉效果但在透镜划伤或污染后会影响光学表现，储存与贴装过程中注意保护；
- 大批量设计前建议进行实际样件验证（电光特性、回流工艺兼容性、在目标环境下的可靠性测试）。
以上为 17-21/T1D-CP2R1TY/4T 的简明技术与应用概述。如需完整电气/机械图纸、回流曲线与分档明细，请参考 Everlight 官方数据手册或联系供应商获取详细资料。

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.
