WP934MD/2GD 是 Kingbright 推出的 3mm 插件型翠绿色(绿翡翠色)指示 LED,标称峰值波长约 565nm,典型发射波长 568nm。该器件以小体积、较窄的发光角度和稳定的电光性能适用于面板指示、信号指示及多种仪器仪表点状显示场合。型号名称中包含 BI-LEVEL 字样,设计上用于常规指示用途;有关是否实现双级发光或引脚结构的具体含义,请在设计前参考原厂详细数据手册确认引脚定义和内部结构。
以上参数为典型/额定值,实际设计中请以厂家数据手册为准,并留有裕量以保证可靠性与寿命。
驱动 LED 时通常使用限流电阻串联,基本公式: R = (Vsup - Vf) / I
推荐驱动电流:为了兼顾亮度与寿命,一般建议在 10–20 mA 范围内工作;25 mA 为最大额定电流,长时间满载工作会降低寿命。
示例计算(以 I = 20 mA 为例,Vf = 2.2 V):
电阻功耗 P = I^2 × R(以 5 V、I=20 mA、R≈150 Ω 为例):P ≈ 0.02^2 × 150 = 0.06 W,建议采用 1/4 W 阻值以保证足够裕量。
若在 25 mA 工作,阻值与功耗相应减少/增加,请在设计时按最大额定值进行热与电流验证。
得益于 50° 的发光角度和中等发光强度(25 mcd),该 LED 更适合近距离点状提示与方向性指示,而不是大面积照明或大视角显示。
总结:WP934MD/2GD 为一款典型的 3mm 翠绿色指示 LED,适用于面板和设备指示领域,具有良好的定向发光特性和稳定的电光参数。设计时请合理选择驱动电流与限流元件,并参考厂家资料进行最终尺寸与电气验证。若需要详细的机械尺寸图、引脚图或 I-V 曲线,请索取 Kingbright 官方数据手册。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
