NFD3401UGD 翠绿色高亮发光二极管产品概述
一、产品简介
NFD3401UGD 为国星光电（NationStar）出品的高亮翠绿色发光二极管（LED），采用标准 3mm 圆形插件封装（D=3mm），单独二极管结构，典型用于面板指示、信号显示及通用照明指示场合。特色为高亮度、窄视角与稳定色坐标，便于聚焦指示与视觉识别。
二、主要电气与光学参数
- 正向电流（If）：20 mA（典型使用值，建议不超过额定值）
- 波长（λd）：515 nm ~ 525 nm（翠绿色）
- 正向压降（Vf）：2.8 V ~ 3.4 V（典型值可取 3.1 V）
- 发光强度（Iv）：约 3500 mcd（在 20 mA 下测得的典型值）
- 发光角度：45°（半值角，集中光束）
- 功率/耗散：约 200 mW（封装最大功耗级别，注意热管理）
- 工作温度：-30 ℃ ~ +85 ℃
三、产品特点与优势
- 高亮度：在 20 mA 工作下可达到约 3500 mcd，视觉效果显著。
- 色彩稳定：波长集中在 515–525 nm，翠绿色表现一致，适合要求色彩一致性的指示应用。
- 窄发光角度：45° 聚光效果好，便于远距或小面积指示。
- 通用封装：3mm 插件封装易于穿孔板装配与手工焊接，可靠性高。
- 宽温度范围：适应工业级温度环境。
四、使用建议
- 驱动方式：建议恒流驱动，典型工作电流 20 mA。如使用限流电阻，可按 R = (Vsup − Vf) / If 计算（例：5 V 供电，取 Vf = 3.1 V，R ≈ (5−3.1)/0.02 ≈ 95 Ω，常取 100 Ω）。
- 串/并联：多颗并联时每颗应有独立限流措施以保证均流。
- 热管理：尽量避免在高环境温度下长期满载工作，必要时降低工作电流或增加散热路径以延长寿命。
- 焊接建议：推荐波峰/手工焊接温度和时间遵循厂方资料（一般焊点温度不宜过高、焊接时间尽量短于 3 秒）。
- ESD 与静电：属静电敏感元件，运输和装配过程中注意防静电措施。
五、典型应用场景
- 仪表面板、指示灯、状态显示
- 家用电器与消费电子指示
- 工业控制面板与信号提示
- 交通与公共信息指示（非高功率信号灯）
六、储存与可靠性
建议在干燥、避光、常温条件下存放，湿度与高温可能影响焊接性与光输出。长期高温高流会加速光衰，建议遵循器件的额定工作条件并做适当降额设计。
总结：NFD3401UGD 是一款面向指示与信号显示的高亮翠绿色 3mm 插件 LED，具有优秀的亮度与色彩一致性，适用于多种通用电子指示类产品。在设计时建议采用恒流驱动并注意热管理与静电防护，以确保长期稳定可靠的使用表现。

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.
