NFD3401HGD — 国星光电 3mm 黄绿色 LED 产品概述
一、产品简介
NFD3401HGD 为国星光电（NationStar）出品的插件式 3mm 圆形黄绿色发光二极管，单颗独立二极管封装。该器件在典型驱动条件下呈现黄绿色发光（峰值波长 565–575nm），人眼对该波段感知亮度高，适用于指示、背光及小型显示点源场合。
二、主要参数
- 正向电流（If）：20 mA（额定）
- 波长（λd）：565–575 nm（黄绿色）
- 正向压降（Vf）：1.8–2.4 V
- 发光强度：150 mcd（典型，测试条件通常为 If=20mA）
- 功率：75 mW（额定）
- 发光角度：40°（较窄的发光角，光束集中）
- 工作温度：-30 ℃ ~ +85 ℃
- 灯头类型 / 封装：3 mm 圆形透镜，插件（D = 3mm）
- 二极管配置：独立二极管
三、特性与优势
- 视觉感知亮度高：565–575 nm 接近人眼峰值灵敏区，黄绿色在指示灯与信号显示中表现醒目且易识别。
- 光束集中：40° 发散角适合点状照明和精确指示，不易漫射。
- 标准插件封装：3mm 常见尺寸，便于手工或自动插件安装和替换。
- 宽工作温度：-30 至 +85 ℃ 能适应一般工业与消费类环境。
四、典型应用
- 面板指示灯、状态显示与信号指示
- 按键/控制板背光与位置指示
- 仪器仪表、电子玩具与家电指示灯
- 交通/照明辅助器件中点光源应用
五、使用建议与注意事项
- 驱动与限流：建议恒流驱动或串联限流电阻。示例（以 5V 电源、Vf 取典型 2.1V 为例）：R = (5 − 2.1) / 0.02 ≈ 145 Ω → 取 150 Ω；电阻耗散 P ≈ (5 − 2.1) × 0.02 ≈ 0.058 W，选择 0.125 W 或更大功率电阻。
- PWM 调光：可用 PWM 进行亮度控制，建议频率 > 200 Hz 以避免可见闪烁，驱动电流峰值勿超出额定 20 mA。
- 热管理：尽管单颗功耗较低，但在高环境温度或密集布置时应注意散热，确保结温与环境温度在器件允许范围内。
- 焊接与装配：遵循插件 LED 的通用焊接规范，避免长时间高温焊接以防封装黄化或内部应力；装配时避免对灯头施加过大机械力。
- ESD 与存储：遵守静电防护（ESD）措施，避免潮湿环境长期存放，必要时密封干燥包装。
六、封装与订购信息
型号：NFD3401HGD；品牌：国星光电；封装形式：插件（D=3mm 圆头）；二极管配置：独立单颗。订购时请注明工作条件（驱动电流、测试条件）以便获取对应的光学、电气曲线与批次数据。对批量测试或特殊要求（如波长分选、亮度分级）可与供应商沟通定制服务。

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.
