AA4040CGSK 产品概述
一 概览
AA4040CGSK 是 Kingbright 出品的一款黄绿色（黄绿）高效率贴片 LED，透明透镜，独立二极管封装，典型用于面板指示、背光、信号指示与通用照明点光源。封装尺寸为 SMD 4×4 mm，发光角度宽达 120°，适合视角要求大的应用场景。
二 主要技术参数
- 发光颜色：黄绿色
- 峰值波长：574 nm，波长（中心）：570 nm
- 正向电压 (Vf)：典型 2.5 V（If=20 mA）
- 额定正向电流：20 mA；最大功耗：75 mW
- 发光强度：90 mcd（基准测量条件）
- 发光角度：120°（半峰全角）
- 透镜：无色透明透镜
- 二极管配置：独立二极管（单体）
- 工作温度：-40 ℃ 至 +85 ℃
三 光学特性说明
574 nm 的峰值表明该器件位于黄绿光谱区，视觉亮度感知较高，适合在人眼敏感区提供良好可视性。90 mcd 的发光强度在视距较近或增强对比的面板指示中表现良好；若用于远距离可视需并联或提高驱动电流并注意热管理。
四 电气与驱动建议
典型驱动条件为 If=20 mA，Vf≈2.5 V。实用电路中建议恒流驱动或在限流电阻前端加恒压源计算：
- 例如 5 V 电源：限流电阻 R = (5 V − 2.5 V) / 20 mA = 125 Ω（取 120 Ω/130 Ω 标准值，并注意功耗）
- 最大功率 75 mW 意味着单颗 LED 在 20 mA 条件下功耗约 50 mW（2.5 V×20 mA），在并联多颗时需考虑总功耗与电源能力。
五 封装与安装注意
4×4 mm SMD 封装利于高速贴装与回流焊工艺。建议参考 Kingbright 官方焊盘推荐稿，预留合适的热扩散铜箔，并在 PCB 设计时考虑焊点可靠性。回流曲线需与无铅焊接规范一致，避免过高峰值温度和过长保温时间。
六 温度与可靠性
工作温度范围宽（-40 至 +85 ℃），但长期高温会降低发光效率和寿命。若在高环境温度或高驱动电流下使用，应加强散热（增大铜箔面积、通孔散热或降低驱动电流），并做加速老化测试以评估光衰。
七 应用场景与选型建议
适用于工业面板指示、家电显示、按键指示、仪表灯及装饰性点光源。选型时关注亮度需求、视距与工作温度；若需要更高亮度可选同系列高亮版本或并联多颗驱动。对于高可靠性场合，建议进行温升试验和长期寿命验证。
八 使用与质量提示
- 储存与贴装前注意防潮处理（如需）；
- 回流焊后建议进行光、电测试以筛选不良；
- 避免长时间在额定电流以上运行以延长寿命；
- 参考 Kingbright 的详细规格书与推荐焊盘图进行最终设计。
如需规格书 PDF、封装带字库或样品参数曲线（IV、光谱、光强随电流/温度的变化曲线），可提供进一步支持与设计资料。

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.
