KP-2012EC 产品概述

一、产品简介

KP-2012EC 是 Kingbright 系列的红色 Chip LED(0805 封装,尺寸约 2.0 × 1.25 mm),采用无色透明透镜,发光颜色为红色。该器件体积小、发光均匀,适合用于背光、指示、仪表及空间受限的消费电子和工业类产品中。

二、主要电光参数

  • 发光颜色:红色
  • 正向压降 (Vf):2.5 V
  • 额定正向电流:20 mA(典型工作电流)
  • 最大功率耗散:75 mW(器件最大承受功率)
  • 工作时功率(20 mA):约 50 mW(2.5 V × 0.02 A),低于器件额定功率
  • 峰值波长:627 nm;波长标称:617 nm
  • 发光强度:15 mcd(指示级亮度)
  • 发光角度:160°(广视角)
  • 工作温度范围:-40 ℃ ~ +85 ℃

三、封装与机械特性

  • 标准封装:0805(行业标准 SMD)
  • 芯片型贴片 LED,透明透镜,适合表面贴装工艺(SMT)。
  • 小体积便于高密度 PCB 布局,适配自动化贴装与回流焊流程。

四、典型应用

  • 面板指示灯、状态指示与按键背光
  • 便携设备与穿戴产品(受限空间的视觉指示)
  • 消费类电子、家电、仪器仪表的信号提示
  • 低功耗显示与装置指示(采用较低驱动电流也能获得可接受亮度)

五、选型与使用建议

  • 驱动限流:建议使用串联限流电阻或恒流源。举例:在 5 V 电源下,R = (5 − 2.5) / 0.02 ≈ 125 Ω;在 3.3 V 电源下,R = (3.3 − 2.5) / 0.02 ≈ 40 Ω。为延长寿命或降低功耗,可将工作电流降至 5–10 mA。
  • 功率与热管理:器件在 20 mA 时功耗约 50 mW,低于最大 75 mW,但长期高温环境下建议降额使用以提高可靠性。
  • 光学考量:160° 广视角适合均匀指示,但若需更集中光束或更高强度,应选择透镜或封装不同的 LED。

六、焊接、储存与可靠性

  • 焊接工艺:兼容常规回流焊(遵循 Kingbright 推荐的温度曲线),避免超温或长时间高温暴露。
  • 储存:避免潮湿和强光照射,长时间储存建议密封防潮。
  • 可靠性:工作温度范围宽 (-40 ℃ ~ +85 ℃),在高温或高电流条件下需考虑降额策略以保证长期稳定。

七、结论

KP-2012EC 以小型 0805 封装、稳定的红色发光和广角光分布,适合各类需要微型指示灯的应用。设计时注意限流与热管理,依据电源电压合理计算串联电阻并在高温环境中适当降额使用,可获得长期可靠的使用效果。有关精确 PCB 焊盘尺寸与回流曲线,建议参考 Kingbright 官方数据资料。

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
