17-21/GHC-XS2T2M/4T 产品概述
一、产品简介
17-21/GHC-XS2T2M/4T 为台湾亿光（EVERLIGHT）出品的绿色高亮贴片LED，采用0805（2.0 × 1.25 mm）封装，单体为独立二极管配置，透明无色透镜，提供大视角与稳定发光性能，适用于空间受限的表面贴装指示与背光应用。
二、主要规格
- 发光颜色：绿色
- 峰值波长：518 nm；标注波段：520–525 nm
- 正向电流（If）：25 mA（典型使用值）
- 正向压降（Vf）：2.75 V ~ 3.95 V
- 功率耗散：95 mW（额定）
- 发光强度：225 mcd ~ 450 mcd
- 发光角度：140°（广角分布）
- 工作温度范围：-40 ℃ ~ +85 ℃
- 封装：0805 SMT；透镜：无色透明；二极管配置：独立二极管
三、电学与光学特性说明
该器件在25 mA驱动下可达到中高亮度输出（225–450 mcd），峰值光谱集中于518 nm，视觉上呈纯正绿色。宽视角（140°）保证从较大入射角仍有良好可见性，适合指示灯与大面积视觉提示。Vf 范围较宽，设计驱动电路时需预留容差。
四、封装与焊接建议
0805小型封装适合高密度SMT布局。推荐采用常规无铅回流工艺（遵循JEDEC回流曲线）。焊膏印刷应保证适量焊膏以避免虚焊或焊球。为获得可靠焊点，焊盘铜箔面积应左右平衡，避免单侧过大引起偏析。
五、驱动与热管理建议
- 驱动方式：优先采用恒流驱动；若使用限流电阻，可按公式 R = (Vs - Vf) / If 计算（举例：5 V 供电、Vf 取典型3.0 V、If=25 mA → R≈80 Ω，选用82 Ω）。
- 功率与温升：器件额定功率95 mW，连续25 mA工作时注意Vf造成的功耗（P = Vf × If）。在高环境温度或密集布置下需考虑降低平均电流或增加间距以降低结温。
- 脉冲驱动应控制占空比与峰值电流，确保不超过脉冲和平均功耗限制。
六、典型应用场景
- 消费电子指示灯（电视、机顶盒、音响）
- 仪表与面板指示
- 便携设备和可穿戴设备局部背光
- 工业控制面板、信号指示与状态显示
七、可靠性与环境适应
工作温度范围宽（-40 ℃ 至 +85 ℃），适合室内外一般工业与民用环境。推荐在设计阶段参考厂商的静电、回流、湿热与盐雾试验数据以满足特定可靠性要求。
八、选型与采购建议
在选择时关注要求的发光强度等级与正向压降范围，若需严格亮度匹配可与供应商确认Bin等级。0805封装适合自动化贴装，适量备货可减少生产波动带来的Bin差异影响。若用于高可靠性产品，建议索取完整的规格书与可靠性测试报告以便验证。

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.
