NFD5408UYD 产品概述
一、产品简介
NFD5408UYD 为国星光电（NationStar）出品的高亮黄色 5mm 圆头穿件型发光二极管。单颗独立二极管封装，发光颜色为黄光，峰值波长在 585nm–595nm 区间，适合指示、显示和光学提示等应用场景。产品设计兼顾光效和可靠性，工作温度范围宽（-30℃ 到 +85℃），适用于多种工业与消费电子环境。
二、主要参数
- 正向电流（IF）：20 mA（典型驱动电流）
- 正向压降（Vf）：2.4 V（典型值）
- 波长（λp）：585 nm ~ 595 nm（黄色）
- 发光强度：700 mcd（IF = 20 mA 条件下典型）
- 发光角度：30°（窄角，高方向性）
- 功率：75 mW（标称）
- 封装形式：穿件（插件），D = 5 mm 圆头
- 工作温度：-30℃ ~ +85℃
- 二极管配置：独立二极管（单颗独立发光单元）
- 品牌：国星光电（NationStar）
三、光电性能与驱动建议
在标准条件下（IF = 20 mA），典型 Vf ≈ 2.4 V，光强约 700 mcd。驱动电源选择时常用恒流源或串联限流电阻：
- 5 V 电源：R = (5.0 − 2.4) / 0.02 ≈ 130 Ω → 采用 150 Ω/1/4W 电阻安全可靠。
- 12 V 电源：R = (12 − 2.4) / 0.02 ≈ 480 Ω → 采用 470 Ω/1/2W 电阻。
推荐恒流驱动或 PWM 调光（频率建议 > 200 Hz 以避免可见闪烁）。峰值驱动需注意不超过最大允许电流（一般不建议长期超过 20–25 mA），并进行热管理与占空比限制。
四、机械与封装信息
5mm 圆形透镜头，窄发散角（30°）提供集中光束，利于指示灯、光导和短距离光学传输。穿件式引脚便于手工焊接与自动插件设备装配。存储与装配时注意静电防护与避免高温长时间回流焊（如需波峰焊，请参考厂商回流/波峰焊曲线）。
五、典型应用
- 面板指示灯与状态指示（工业控制、仪表）
- 消费电子指示（家电、照明开关）
- 仪器/设备的光学提示点或聚光指示
- 光学对位、短距离光学信号显示
六、可靠性与环境适应
工作温度范围宽，耐环境能力较好。长期高温或过流会导致亮度下降和寿命缩短，建议在高温环境下进行电流降额（如超过 60℃ 时适当降低驱动电流）。注意防潮、防静电、防机械冲击以保证产品长期可靠性。
七、注意事项与建议
- 推荐使用恒流驱动器或合适的限流电阻并考虑驱动电路的热耗散。
- PWM 调光应选择足够高频率，避免在光学拾取或人眼可见范围内产生闪烁。
- 装配时遵循 ESD 防护规范，避免静电损伤。
- 如果需经常在高温或高湿环境工作，请与供应商确认可靠性测试数据与加速寿命评估。
以上为 NFD5408UYD 的产品概述与使用建议，适用于快速选型与应用参考。若需完整数据手册或可靠性试验报告，建议向国星光电获取原厂资料。

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.
