NFD3901URUGW-A 产品概述
一、产品简介
NFD3901URUGW-A 为国星光电（NationStar）出品的 3mm 圆形双色 LED（红 / 翠绿），采用插件封装，针脚间距 P=2.54mm，二极管配置为共阴极。器件针对信号指示与面板显示设计，45°发光角度，工作温度范围宽，适合工业与消费电子环境使用。
二、主要参数
- 发光颜色：红色（波长 620–630nm）、翠绿色（波长 515–525nm）
- 正向电压 Vf：红色 1.8–2.4V；绿色 2.8–3.4V
- 额定正向电流 If：20mA（最大）
- 功率/光学：单色功率等级 75mW / 100mW；发光强度标准款 400mcd， 高亮款 4000mcd（视型号）
- 发光角度：45°
- 工作温度：-30℃ ~ +85℃
- 封装形式：插件（穿孔），针脚间距 2.54mm（适配标准面板/插座）
三、电气与驱动建议
- 驱动方式：共阴极，建议将阴极接地（GND），通过限流电阻将阳极接至驱动电源或 MCU 输出。
- 限流电阻计算示例（以 20mA 设计）：
- 红色（典型 Vf≈2.1V），5V 电源：R≈(5−2.1)/0.02≈145Ω（取 150Ω）；12V 电源：≈500Ω。
- 绿色（典型 Vf≈3.1V），5V 电源：R≈(5−3.1)/0.02≈95Ω（取 100Ω）；12V 电源：≈450Ω。
- 推荐工作电流：为延长寿命与降低发热，建议常用电流 10–15mA，短时脉冲可达 20mA（注意平均功率限制）。
四、封装与装配
- 尺寸与安装：3mm 灯头，适合标准 3.0mm 安装孔，针脚间距 2.54mm 便于与常用板对接。
- 焊接：插件型，适用手工焊接与波峰焊；波峰焊温度与时间应符合国星提供的焊接规范以避免光学衰减。
五、可靠性与注意事项
- 环境适应：-30℃ ~ +85℃，适合多数室内及轻工业应用。
- ESD 与反向电压：LED 对静电敏感，装配与测试时做好防静电保护；避免长期反向电压应用。
- 散热与寿命：避免在高温下长时间满载运行；高亮款在高电流下发热更多，需适当降额。
六、典型应用
- 面板指示灯、状态显示、工业控制面板、仪器仪表、消费类电子产品指示与信号标识。
NFD3901URUGW-A 以稳定的发光效率、标准化插件封装与便捷的驱动特性，为需要双色指示的应用提供了可靠且易于集成的解决方案。若需更详细的引脚图、光电曲线或可靠性数据，可联系供应商索取完整规格书。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
