WP934CB/GD 产品概述

一、产品概况

WP934CB/GD 为 Kingbright 系列 3mm 指示型 LED(标称 565nm 峰值,雾状绿色透镜)。该器件在标准工作条件下呈黄绿色发光,透镜为雾状绿色以获得均匀柔和的出光效果,适合面板指示与状态显示等场合。

二、主要电气与光学参数

  • 发光颜色:黄绿色(黄绿)
  • 峰值波长:565nm;波长(典型):568nm
  • 正向电流(If):10mA(推荐工作电流)
  • 正向压降(Vf):2.0V ~ 2.4V(在 If=10mA 条件下)
  • 发光强度:10mcd ~ 25mcd(If=10mA)
  • 发光角度:50°(中心指向性良好)
  • 功率:62.5mW(器件标注值);实际工作耗散约 Vf × If ≈ 20mW ~ 24mW(在 10mA 时)
  • 工作温度:-40℃ ~ +85℃
  • 透镜:雾状绿色(扩散,减少眩光)
  • 封装:3mm(具体封装细节请参照官方 Datasheet)

三、特性与优势

  • 色彩稳定:565nm 峰值配合雾状透镜,视觉上黄绿色饱和且柔和,适合指示与面板显示。
  • 视角适中:50° 的发光角度在近距离面板、仪表指示中提供良好可见性且不易漏光。
  • 宽温区工作:-40℃~+85℃,满足工业级环境要求。
  • 低功耗:在 10mA 工作点下实际耗散小,便于电源与热管理设计。

四、典型驱动与电路示例

  • 恒流驱动优先:建议使用恒流源或限流电阻驱动以保证亮度一致性与器件寿命。
  • 串联限流电阻计算:R = (Vs - Vf) / If。示例:
    • 5V 电源:取 Vf=2.2V,If=10mA,则 R ≈ (5 - 2.2)/0.01 = 280Ω,常用 270Ω/1/4W 或 330Ω/1/4W(调节亮度)。
    • 3.3V 电源:取 Vf=2.2V,则 R ≈ 110Ω,常用 120Ω/1/4W。
  • 功率考虑:电阻功耗 P_R = (Vs - Vf) × If(例如 5V 情况下约 28mW),LED 功耗按 Vf×If 计(约 22mW)。
  • 调光建议:采用 PWM 调光时频率建议 >1kHz 以避免可见闪烁;占空比控制亮度。

五、可靠性与使用注意

  • ESD 与静电防护:LED 属静电敏感器件,建议在装配与测试时做好静电防护。
  • 焊接工艺:若采用回流或波峰焊,请遵循制造商的温度曲线与时序,避免过高温度或过长加热造成光衰。
  • 反向电压:避免施加过高反向电压(参照 Datasheet 的最大反向电压限制)。
  • 老化与分选:发光强度存在批次与筛选(bin)差异,量产时建议按光强和色度分bin以保证一致性。

六、应用场景与选型建议

  • 适用:面板指示灯、仪表显示、家电指示、信号指示与低功耗背光等。
  • 选型提示:目前封装标注为 3mm,但具体引脚长度、封装形态(直插/直角/弯脚)请向供应商索取 Datasheet 与样品确认;若对亮度、色度一致性要求高,应要求 bin 分选与光谱曲线。

备注:以上参数以您提供的数据为准。购买与生产应用前,建议下载 Kingbright 官方 Datasheet 或联系供应商确认完整规格、最大额定值及焊接曲线。

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
