APHHS1005LCGCK 产品概述

一、产品简介

APHHS1005LCGCK 是 Kingbright 出品的一款 0402 封装黄绿色(yellow-green)贴片 LED。该器件以小体积、低功耗和较宽视角为特点,适合用于空间受限的指示与背光应用。典型工作点为正向电流 2mA,正向压降约 1.9V,峰值波长 574nm,呈现清晰的黄绿色光色。

二、主要参数

  • 发光颜色:黄绿色(yellow-green)
  • 峰值波长:574 nm(典型)
  • 波长:570 nm(典型)
  • 正向电流(If):2 mA(工作点)
  • 正向压降(Vf):1.9 V(在 2 mA)
  • 功率:75 mW(最大额定功率)
  • 发光强度:3.5 mcd(典型,2 mA)
  • 发光角度:120°(典型)
  • 透镜颜色:无色透明透镜
  • 环境温度范围:-40 ℃ ~ +85 ℃
  • 封装:0402(超小型 SMD)
  • 品牌:Kingbright

三、光学与电气特性说明

该器件的峰值波长 574 nm 属于黄绿色区域,视觉感受偏绿。发光强度约 3.5 mcd(在 2 mA 下为典型值),配合 120° 的大视角,适合状态指示和面板可视性要求不高但需较宽可见范围的场合。正向压降约 1.9 V,工作电流仅 2 mA,功耗极低,适合电池供电或低功耗系统。

需要注意,Vf 与亮度会随温度和生产批次(bin)有一定漂移,设计时应留有裕量并参照实际数据手册和样品测试结果。

四、典型应用场景

  • 面板/仪表状态指示灯(电源/工作/报警指示)
  • 消费类电子产品的指示与背光(耳机、遥控器、小型家电)
  • 可穿戴设备、IoT 终端和微型传感器节点的指示灯
  • PCB 上空间受限的指示阵列或信号指示
  • 低功耗指示与提示功能场合

五、设计与驱动建议

  • 驱动方式:建议采用恒流驱动或串联限流电阻方式确保稳定亮度与可靠性。
  • 限流电阻计算(以 2 mA 目标电流为例):
    • 3.3 V 电源:R = (3.3 − 1.9) / 0.002 = 700 Ω,常用值 680 Ω 或 750 Ω。功耗 P = I^2·R ≈ 2.8 mW。
    • 5 V 电源:R = (5 − 1.9) / 0.002 = 1 550 Ω,常用值 1.5 kΩ。功耗 P ≈ 6.2 mW。
  • 驱动电流:2 mA 为推荐工作点;若需要更高亮度可短期提高电流,但应参考最大额定电流并注意散热与寿命影响。
  • 多路扫描/矩阵驱动时应考虑占空比和峰值电流对平均亮度与热耗的影响。
  • ESD 防护:LED 芯片对静电敏感,装配与测试时应采取常规静电防护措施(接地腕带、工作台接地等)。

六、封装与焊接注意事项

  • 0402 封装尺寸极小,焊盘与锡膏用量需精准控制,建议参考 IPC 推荐的 0402 焊盘设计或 Kingbright 的封装建议。
  • 贴装:推荐使用自动贴片设备(pick-and-place)进行安装,避免手工过度机械挤压造成损伤。
  • 回流焊:建议遵循厂商推荐的回流温度曲线;若无明确曲线,采用常规 SMD 回流参数(预热、回流峰值及时间受 PCB 和元件限制)并避免过度升温或长时间高温,以免影响 LED 光学性能与寿命。
  • 清洗:若需清洗,应选择对环氧/透镜友好的清洗剂并避免高压冲洗引起机械应力。

七、可靠性与存储

  • 使用寿命受驱动电流、工作温度及环境湿度影响,长期高温或过高电流会加速老化并导致亮度衰减。
  • 存储时建议防潮、防尘、避光,尽量在干燥箱内保存并按先入先出的原则使用。若包装为卷带(T&R),按厂商说明回流前进行必要的烘干处理(若包装提示为需烘烤的湿敏等级)。

八、采购与替代建议

APHHS1005LCGCK 由 Kingbright 提供,购前建议索取并确认最新数据手册以获取完整的电气/光学曲线、回流曲线、封装图与焊盘建议。常见采购形式为卷带供货(T&R),具体包装数量与交期请咨询授权代理或 Kingbright 官方渠道。若需要更高亮度或不同色调,可参考 Kingbright 同系列或同色域的 0402/0603 封装替代型号。

总结:APHHS1005LCGCK 以超小 0402 封装、低功耗和宽视角为优势,适合对尺寸与能耗有严格要求的指示类应用。设计时重视驱动、焊接与热管理,可在保证可靠性的前提下发挥其体积与效率优势。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
