NFD3401UYD 产品概述

一、产品简介

NFD3401UYD 为国星光电(NationStar)推出的黄色发光二极管,采用直径3mm圆形灯头插件封装,单独二极管结构,视角约70°,适合面板指示、信号提示及一般背景照明等应用。器件在常见驱动条件下提供稳定的黄色光色,可靠性和加工适配性良好。

二、主要参数

  • 发光颜色:黄色
  • 峰值波长:585nm ~ 595nm
  • 正向电流(典型):20 mA
  • 正向压降(Vf):1.8 V ~ 2.4 V
  • 发光强度(典型):250 mcd
  • 发光角度:70°
  • 标称功率:75 mW(厂商标称)
  • 工作温度:-30 ℃ ~ +85 ℃
  • 封装形式:插件,D = 3 mm
  • 二极管配置:独立二极管

三、结构与封装特点

NFD3401UYD 采用标准3mm圆头透镜,插件式引脚便于穿板安装与更换维护。透镜与芯片配合提供均匀的出光分布,70°视角兼顾指示性与侧向可视范围。独立二极管结构意味着每颗发光体为单一封装单元,便于单点驱动和故障替换。

四、电光特性与驱动建议

为保证寿命与光学一致性,推荐采用恒流驱动,常用电流为20 mA;亦可通过PWM调光实现亮度控制。驱动电源应限制电流并避免突发浪涌。器件电功率消耗以 Vf × If 计算,实际工作功率受正向压降与驱动电流影响,应确保不超过厂商额定功率。高频PWM调制时注意频率与占空比对光学感知与热负荷的影响。

五、热管理与工作环境

器件额定工作温度为-30 ℃ 至 +85 ℃。由于3mm小封装热阻相对较高,建议在设计时考虑散热路径与布局,避免在高环境温度或密闭空间长时间满载工作。高温下应适当降额使用以延长寿命。包装、焊接和操作过程中注意ESD防护和机械应力控制。

六、典型应用场景

  • 面板指示灯、状态指示器
  • 消费电子和家用电器指示
  • 工业设备信号提示
  • 仪表盘与控制台的视觉提示
  • 背光点亮与装饰性照明(低功率场合)

七、采购与质量注意

NFD3401UYD 由国星光电出品,适配常规插件装配工艺。采购时请确认完整型号、光电测试条件(驱动电流、测角、测试温度)以及批次一致性。项目设计前建议参考厂商完整版数据手册,获取焊接建议、绝对最大额定值和可靠性测试结果,以确保长期稳定运行。

总结:NFD3401UYD 以其稳定的黄色发光、标准3mm插件封装和良好的可视性,适合各类指示与信号应用。在实际设计中关注驱动、电功率与热管理,可获得良好的性能与寿命表现。

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.

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
