NFD3401BC(国星光电)产品概述

一、产品简介

NFD3401BC 是国星光电推出的一款高亮蓝色LED,采用直插式(D=3mm)透明透镜封装。发射波长位于460nm~470nm范围,视为纯净蓝光输出,适用于需要高亮度、小光束角的指示、照明与显示应用。

二、主要技术参数

  • 发光颜色:蓝色
  • 波长(λd):460nm ~ 470nm
  • 正向电流(If):20mA(典型驱动电流)
  • 正向压降(Vf):2.8V ~ 3.4V
  • 光强(Iv):4500mcd(在标准测试条件下)
  • 发光角度:30°(窄光束)
  • 功率耗散:200mW
  • 工作温度:-30℃ ~ +85℃
  • 透镜颜色:无色透明透镜
  • 封装:插件(直插),透镜直径3mm

三、产品特性

  • 高光强:单颗光强约4500mcd,在20mA驱动下可获得良好可视效果。
  • 窄发光角:30°聚光设计,适合点光源、光束指示或需定向照明的场景。
  • 稳定的蓝光光谱:460–470nm范围内光色一致性好。
  • 结构可靠:插件式3mm封装,便于手工或波峰/回流焊装配(遵循焊接工艺规范)。

四、典型应用

  • 精密指示灯(设备面板、控制器)
  • 点光源照明与装饰灯(导光、光纤耦合)
  • 小型显示与符号背光
  • 光学传感与可见光通信(需考虑驱动与调制方案)

五、安装与使用建议

  • 驱动方式:建议恒流驱动,典型驱动电流20mA。串联限流电阻计算示例(以5V供电、Vf取3.1V为例):R = (5V − 3.1V) / 0.02A ≈ 95Ω(可选100Ω)。
  • 热管理:单颗功率耗散200mW,长时间高电流/高环境温度下应注意降额使用以延长寿命。
  • 焊接与存储:遵循元件厂商焊接温度与防潮说明,避免长时间高温或潮湿环境。元件具有ESD敏感性,装配时应采取防静电措施。

六、可靠性与注意事项

  • 工作温度范围为-30℃至+85℃,超出此范围可能影响光输出和寿命。
  • 长期或高温驱动可能导致亮度衰减,应合理选取驱动电流与散热方案。
  • 蓝光强度较高,直视可能有视觉不适或潜在眼部风险,装配和使用时避免直视发光面。

七、封装与采购提示

  • 封装形式为直插(插件)3mm透明透镜,便于样机验证与手工焊接。
  • 采购时请确认批次光色一致性与IV曲线要求,如需严格色容差或高可靠性等级,可向供应商索取完整数据手册与老化测试报告。

如需更详细的电气特性曲线、光谱分布图、封装外形尺寸或焊接工艺建议,可联系供应商获取NFD3401BC的完整数据手册。

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
