NFD3401WC 产品概述
一、产品简介
NFD3401WC 是国星光电推出的一款高亮度白光插件 LED，封装为通孔式 D=3mm 圆头透明透镜，色温 6000K~9000K，属冷白光范畴。该器件在推荐驱动电流 20mA 条件下，具有较小的发光角度（20°）和集中的光强输出，适合需要点光源或定向照明的场合。
二、主要性能参数
- 发光颜色：白色
- 色温：6000K ~ 9000K（冷白）
- 正向电压（Vf）：典型 3.4V（20mA）
- 正向电流：20mA（最大/典型驱动值）
- 功率：200mW（器件额定功耗）
- 发光强度：25,000 mcd（在指定测试条件下）
- 发光角度：20°（典型，窄光束）
- 透镜颜色：无色透明透镜
- 工作温度范围：-30℃ ~ +85℃
三、产品特点
- 高亮度点光源：25,000 mcd 的高发光强度，适合指示、光点照明及远距可视指示。
- 窄角度聚光：20° 的小角度设计，有利于实现更远距离的照射与更高的中心亮度。
- 冷白色光谱：6000K~9000K，色温偏蓝白，显色适用于仪表指示、背光及工业照明。
- 可靠的通孔封装：3mm 插件形式，便于手工或波峰焊装配，机械强度好，安装方便。
四、典型应用场景
- 仪表与显示面板指示灯
- 精密定位或点光源照明（如光学定位、读码）
- 工业设备、控制柜指示
- 车用或交通指示（需符合相应认证）
- 电子产品外观背光与装饰性照明
五、使用建议与典型电路
- 驱动与限流：建议使用恒流源或串联限流电阻驱动，最大规范电流 20mA。
- 举例：以 5V 电源直接驱动时，限流电阻 R = (5V − 3.4V) / 0.02A ≈ 80Ω，可选 82Ω；功率 P_R ≈ 0.032W（常规 0.25W 足够）。
- 更高电压（如 12V）需更大阻值并选用更高功率电阻（建议 ≥0.5W）。
- 建议寿命与散热：若要求更长寿命与更稳定光通，建议电流降额到 10–15mA 运行，以降低热应力。透明透镜、窄光束使得中心亮度高，注意避免长期在高温环境下工作。
六、封装与可靠性
- 封装：插件（通孔），D=3mm；引脚适用于手插或波峰焊，焊接时避免过长高温暴露以保护封装和芯片。
- 环境适应：工作温度 -30℃ 至 +85℃，适用于大多数室内及部分室外低温环境。建议在高湿或腐蚀性气氛中采取防护措施。
- 防静电与焊接注意：建议在装配过程中采取 ESD 防护，焊接时遵循厂商温度曲线，避免长时间高温直烙。
七、选型与采购建议
- 若需要更宽角度或更高显色性，可考虑同系列不同封装或更高 CRI 的型号。
- 购买时确认色温批次与亮度等级（Bin），以保证多件一致性。国星光电品牌供应渠道稳定，建议向正规代理或直接采购以获得性能与售后保障。
如需具体的电气曲线、机械尺寸图或 BIN 分档资料，可提供进一步的技术资料或查阅国星光电官方规格书以完成设计验证。

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.
