NFD3901URUBW-A 产品概述

一、产品简介

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。

二、主要参数(概要)

  • 封装形式:插件 3mm 圆形灯头,P = 2.54mm
  • 二极管配置:共阴极(共阴脚,通常接地)
  • 发光颜色:红色 / 蓝色
  • 波长(典型):红色 620–630 nm;蓝色 460–470 nm
  • 正向压降 Vf:红色 1.8–2.4 V;蓝色 2.8–3.4 V
  • 额定正向电流 If:20 mA(单色)
  • 额定功率:75 mW / 100 mW(视颜色与封装差异)
  • 光强(典型):红色 850 mcd;蓝色 650 mcd
  • 发光角度:45°
  • 工作温度:-30 ℃ 至 +85 ℃
  • 品牌:国星光电(NationStar Optoelectronics)

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。

三、电气与热特性要点

  • 正向电流 If = 20 mA 为常用驱动电流。建议在设计中使用限流电阻或恒流驱动器以保证稳定亮度与延长寿命。
  • 由 Vf 与 If 可估算器件自身功耗:
    • 以中间值计算:红色约 2.1 V × 20 mA = 42 mW;蓝色约 3.1 V × 20 mA = 62 mW,均低于额定功率,具有一定余量。
  • 驱动电阻示例(以 5 V 电源为例):
    • 红色:R = (5.0 − 2.1) / 0.02 ≈ 145 Ω(可选 150 Ω)
    • 蓝色:R = (5.0 − 3.1) / 0.02 ≈ 95 Ω(可选 100 Ω)
  • 若采用 PWM 调光,建议限制峰值电流并考虑平均功耗与散热,避免长期在额定极限上工作。

四、封装与引脚说明(使用提示)

  • 本系列为插件式 3mm 封装,标准引脚间距 2.54 mm,便于与通用 PCB 插孔/插座配合。
  • 共阴极结构:所有阴极引脚内部分连通,共用接地/负电位;每种颜色有独立阳极引脚,驱动时对相应阳极施加正电压即可点亮该色。具体外形尺寸与引脚位置请参照官方机械图与引脚排列。
  • 手工焊接或波峰焊时请遵循厂商焊接温度与时间建议,避免过高温度或过长预热而影响发光二极管寿命。

五、安装与可靠性注意事项

  • 工作环境温度范围 -30 ℃ 至 +85 ℃,适合室温与多数工业环境,但若用于高温场所需评估散热及寿命。
  • 防静电:LED 对静电敏感,装配与测试时应采取防静电措施(接地腕带、静电台面等)。
  • 清洗与化学兼容性:若需清洗 PCB,请确认所用清洗剂不会侵蚀或污染 LED 外壳与封装材料。
  • 老化与一致性:为保证批次一致的亮度与色位,建议在生产线上进行预老化或分选。

六、典型应用

  • 指示灯与状态显示(电源、网络、故障指示)
  • 仪表与控制面板
  • 消费电子(遥控设备、玩具、家电指示)
  • 工业控制与测试设备 (因发光角度较小,适合点状、聚焦型指示,而非大面积照明或背光)

七、总结与建议

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。

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
