KA-3528SGC — Kingbright 绿色高亮单色 LED 概述

一、产品简介

KA-3528SGC 是 Kingbright 推出的超高亮绿光单色表面贴装(SMD)LED,峰值波长为 565 nm,适用于需要醒目绿色指示或背光的电子产品。器件采用小尺寸 SMD-4P 封装(3.5 × 2.8 mm),2 引脚独立二极管结构,透明无色透镜,发光角度宽达 120°,便于面光或散射式照明设计。

二、主要规格要点

  • 发光颜色:绿色(峰值波长 565 nm)
  • 正向压降(Vf):典型 2.2 V
  • 最大功率耗散:105 mW
  • 发光强度:12.5 mcd ~ 40 mcd(见数据手册中的测试条件)
  • 发光角度:120°(半功率角)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 二极管配置:独立二极管,2 引脚
  • 透镜:无色透明透镜
  • 封装:SMD-4P,封装尺寸 3.5 × 2.8 mm
  • 包装形式:T/R(卷带包装,适用于自动贴装)

三、光学与电气特性说明

该元件在可见光谱中呈现饱和绿光,565 nm 的峰值波长在人眼感知中属于高显色、辨识度高的绿色区域。发光强度范围 12.5~40 mcd 适合指示灯与面光源应用。正向压降约 2.2 V,为常见逻辑/单电池供电系统设计提供便利。请根据应用场景和亮度要求选择合适的驱动电流;常见做法是在限流电阻或恒流驱动下工作,以保证亮度一致并保护 LED 寿命。示例:若使用 5 V 直流电源并以 10 mA 驱动,限流电阻约为 (5 V − 2.2 V) / 10 mA ≈ 280 Ω(仅为示例,实际应按目标电流与热管理要求确定)。

四、封装与机械信息

KA-3528SGC 为小型 SMD 封装(3.5 × 2.8 mm),透明透镜使光分布更均匀,适用于贴片生产线的高速贴装与回流焊工艺。器件为卷带(T/R)包装,便于 SMT 自动化装配。由于为独立二极管配置,焊盘与布线时应注意极性标识与焊盘尺寸匹配,避免热应力导致粘接或机械损伤。

五、典型应用场景

  • 面板指示灯与状态显示
  • 工业仪器与控制面板指示
  • 家电与消费电子指示与背光
  • 医疗设备状态指示(在满足温湿度与安全要求下)
  • 交通信号与标示(小功率指示用途)

六、选型与使用建议

  • 请参考 Kingbright 官方数据手册,确认测试条件(驱动电流、测量距离、脉冲/直流条件等)与典型光电参数。
  • 采用适当的限流电阻或恒流驱动,以避免过流导致亮度衰减或损坏。
  • 组装时遵循常规 SMT 回流焊工艺及厂商推荐曲线,开启防静电与干燥包装管理,避免潮湿回流引发焊接缺陷。
  • 长期高温或过流会加速光衰,必要时留出散热路径并进行热沉或降额设计。
  • 对环境耐受性有更高要求(例如汽车电子、长期户外应用),请在选型前确认额定和认证信息。

总体而言,KA-3528SGC 在体积小、视角宽、绿色显色良好的前提下,适合多种指示与照明场合,是常见的工业与消费类电子产品中的可靠选择。若需更详细的电气表格、光谱曲线或回流焊建议,请参照 Kingbright 数据手册或提供具体应用条件以便进一步评估。

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.

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
