17-21/GHC-YR1T1/4T 产品概述
一、产品简介
17-21/GHC-YR1T1/4T 是台湾亿光（EVERLIGHT）生产的一款绿色发光二极管（LED），封装为行业通用的 0805 SMD。其电气和光学的基础参数为：正向压降（Vf）3.3V，峰值波长 518nm，光谱范围 520nm~535nm（绿光），无色透明透镜，发光角度 140°，工作温度范围 -40℃ 至 +85℃。该器件定位为通用指示与背光用途的小型发光单元，适合高密度 SMT 组装与自动化生产。
二、主要特性与优势
- 颜色与光效：518nm 峰值对应鲜明绿光，视觉响应良好，适合作为状态指示或色彩显示单元。透明透镜与 140° 的大视角设计，提供宽广的可视范围，减少方向性依赖。
- 小型化封装：0805 尺寸利于高密度 PCB 排布，节省空间，便于多点排列或矩阵应用。
- 宽温适应性：-40℃ 至 +85℃ 的工作温度满足绝大多数工业与消费电子场景的环境要求。
- 品牌与质量：亿光作为成熟 LED 厂商，量产稳定，适配 SMT 流程，供应链可靠。
三、典型应用场景
- 面板指示灯、状态指示与信号反馈（路由器、家电、工控设备等）。
- 按键背光与功能区照明（仪表盘、小型显示器）。
- 标志性点光源与装饰照明（控制面板、便携设备）。
- 多色混合或矩阵阵列显示系统中作为绿光单元。
四、驱动与电路建议
- 器件标注 Vf 为 3.3V，实际驱动时应依据电源电压选择合适的限流电阻或恒流驱动。若使用串联限流电阻，建议先确认目标工作电流（常见范围 1–20mA，具体以光强与散热需求确定），再按公式 R = (Vsup - Vf) / If 计算。
- 推荐在 PCB 设计时考虑并联冗余与热量分布，避免单点过流或散热集中。
五、封装与焊接注意事项
- 0805 尺寸要求合理的焊盘设计与助焊膏印刷工艺，以保证贴装与焊接良好性。可参考行业标准 0805 焊盘尺寸。
- 支持回流焊工艺；具体回流温度曲线应参照亿光提供的封装温度容许书（PCB 材料、助焊膏类型可能影响推荐曲线）。
- 焊接后建议进行外观与电性检验（亮度、正反向电压、焊点完整性）。
六、可靠性与储存
- 工作环境应尽量避免高湿、高腐蚀性气体与强紫外辐照。长期存储建议在干燥、防潮袋内并置于常温低湿环境，开封后建议在规定时间内完成贴装（参照厂商防潮等级说明）。
- 装配与搬运时注意静电防护（ESD），LED 器件对静电与瞬态过流敏感，建议采用常规防静电措施与限流保护。
七、订购与技术支持
- 型号标识为 17-21/GHC-YR1T1/4T，购买时建议核对批次与出货文件（IV 曲线、光谱分布、出货检验报告）。如需精确光学数据（光强、光通量、光束分布曲线）或回流曲线、推荐 PCB 焊盘图，请联系供应商或参考亿光官方数据手册以获得最准确的工程参数与应用建议。

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.
