Kingbright KPT-2012EC 0805封装红色Chip LED产品概述

KPT-2012EC是Kingbright推出的一款0805封装红色Chip LED,以小尺寸、宽视角、宽温适应性为核心优势,广泛应用于各类电子设备的状态指示、小型显示等场景。以下从核心特性、性能参数、应用场景等维度展开详细说明:

一、封装与外观核心特征

KPT-2012EC采用行业通用的0805封装(公制对应2012尺寸),具体外观参数如下:

  • 物理尺寸:2.0mm×1.25mm×0.8mm(长×宽×高),属于超小封装,适合高密度PCB布局;
  • 透镜设计:无色透明透镜——不依赖透镜染色实现红色发光,由芯片直接发射红光,避免透镜老化导致的颜色漂移,长期可靠性更高;
  • 结构形态:Chip型无引脚设计,兼容表面贴装(SMT)工艺,支持回流焊、波峰焊批量生产,集成度高。

二、光电性能关键参数解析

KPT-2012EC的光电参数针对指示类应用做了优化,核心参数及实际意义如下:

1. 发光特性

  • 发光颜色:红色;
  • 主波长:617nm,峰值波长:627nm——属于偏深的红色,视觉辨识度高于浅红色,适合近距离状态指示(如电源灯、故障灯);
  • 发光角度:120°宽视角——光线发散范围大,无需额外透镜即可实现均匀覆盖,降低设计成本,适合面板灯、指示灯等场景。

2. 电学性能

  • 正向压降(Vf):2.5V(@20mA正向电流)——红色LED的常规压降范围(2.0~2.8V),适配大多数5V/3.3V驱动电路;
  • 正向电流(If):额定20mA(最大连续电流)——短时间脉冲电流可适当提高(如30mA),但连续工作需严格控制在20mA以内,避免光衰加速;
  • 功率:75mW——注意:额定工作时(20mA×2.5V)实际功耗为50mW,75mW为最大允许峰值功耗,选型时需避免长期超额定值。

3. 环境适应性

  • 工作温度:-40℃~+85℃——覆盖工业级温度要求,可用于户外设备(如充电桩指示灯)、工业控制设备(如PLC面板)等高低温场景;
  • 存储温度:-55℃~+100℃(未焊接状态),满足常规仓储需求。

三、典型应用场景

KPT-2012EC的小尺寸、宽温特性使其适用于以下场景:

  1. 消费电子指示:小家电(电饭煲、加湿器的电源/状态灯)、遥控器(功能键指示)、无线充电器(电量灯);
  2. 工业控制面板:PLC、变频器、传感器的运行/故障/待机指示;
  3. 通信设备:路由器、交换机的端口状态/电源指示;
  4. 汽车电子辅助:车载充电器、仪表盘辅助指示(需确认汽车级认证,宽温范围支持);
  5. 小型显示模块:7段数码管的小尺寸应用、电池电量矩阵指示。

四、使用注意事项

  1. 限流电阻必须串联:若直接接5V电源,需计算电阻值:( R=(V_{cc}-V_f)/I_f=(5-2.5)/0.02=125Ω ),选120Ω(标准阻值)即可,避免过流烧毁;
  2. 极性识别:LED为单向导电,通常长脚为正极,或通过透镜内芯片的电极标识判断(无标识时需用万用表测试);
  3. 焊接防护:回流焊峰值温度≤260℃(时间≤10秒),避免温度过高损坏芯片;焊接后避免弯曲PCB(防止焊点开裂);
  4. 静电防护:未焊接的LED需用防静电包装存储,避免静电损伤芯片。

五、品牌与可靠性优势

Kingbright作为全球知名LED厂商,KPT-2012EC具备以下可靠性优势:

  • 光衰控制:连续工作1000小时光衰≤5%,寿命≥5万小时;
  • 一致性:批量产品参数偏差小,适合工业化生产;
  • 环保认证:符合RoHS、REACH等国际环保标准,无铅焊接兼容。

综上,KPT-2012EC是一款高性价比的0805红色Chip LED,凭借小尺寸、宽视角、宽温适应性,成为电子设计中状态指示类应用的常用选型。

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
