NFD3901URUBW-A 是国星光电推出的一款高亮度双色 3mm 圆形插件指示灯(共阴极配置),红/蓝双色发光,适用于面板指示、仪表与消费类电子等需要清晰状态指示的场合。器件采用标准 3mm 圆头封装、引脚间距 P=2.54mm,便于 DIP 插装或手工焊接,视角窄(45°),提供集中、可观测性强的光束。
注:以上为基于提供参数的概要,具体引脚排列、典型光学曲线与绝对最大额定值应以厂商最新版数据表为准。
NFD3901URUBW-A 以其 3mm 小巧封装、共阴极配置与红/蓝双色输出,适合需要清晰、可区分状态指示的应用。设计时应注意按 Vf 与 If 正确限流、考虑散热裕度,并参考国星光电最新版数据表确认引脚定义与绝对最大额定值。若需在更宽温度或更高可靠性场景(如车规级)使用,请与供应商沟通或选用相应认证器件。
如需我帮助计算在其它供电电压下的限流电阻、PWM 方案建议或引脚/封装尺寸说明,可提供电源电压和使用场景,我可进一步给出参数化计算与接线示例。

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.
