ROHM SMLP14BCNWT86 — 蓝光 0402 单色贴片 LED 概述
一、产品概述
SMLP14BCNWT86 为 ROHM（罗姆）出品的 0402（1.0 × 0.6 mm）超小型单色贴片 LED，白色透镜、蓝色发光。典型波长 470 nm，正向电压 Vf ≈ 2.9 V（在 IF=5 mA 时），发光强度 约 25 mcd，额定功率 33 mW，工作温度范围 −40 ℃ 至 +85 ℃，适用于高密度、对体积和响应速度有要求的消费电子与指示场合。
二、主要性能参数
- 封装：0402（1.0 × 0.6 mm）方形灯头
- 发光颜色：蓝色（470 nm）
- 正向电流：5 mA（推荐工作点）
- 正向压降：2.9 V（@5 mA）
- 光强：25 mcd（@5 mA）
- 功率：33 mW
- 透镜颜色：白色透镜（扩散/均匀出光）
- 工作温度：−40 ℃ ～ +85 ℃
三、典型应用场景
- 移动终端、可穿戴设备的状态/指示灯
- 工业仪表、家电面板微型指示
- 背光或信号显示（空间受限、需要低功耗场合）
- 医疗便携设备与物联网节点的视觉指示
四、封装与 PCB 设计建议
0402 超小封装需注意焊盘尺寸和贴装精度。建议按制造商推荐的 land pattern 设计焊盘并预留适度热量，使用精细贴装机和回流焊工艺。白色透镜有利于角度分布均匀但会略影响峰值亮度，适合指示和柔和显示。
五、驱动与热管理
推荐工作电流 5 mA，以保证 Vf≈2.9 V 与标称光强。若使用 5 V 供电，简单限流电阻示例：R = (5 − 2.9) / 0.005 ≈ 420 Ω（取标准阻值 430 Ω）；功耗 P_R ≈ I^2·R ≈ 0.005^2·430 ≈ 10.8 mW。高电流驱动会提升亮度但需注意功率与结温限制，长期工作应避免超过额定电流与环境温度上限以保障寿命。
六、可靠性与使用注意
- 建议遵循厂方回流焊曲线和湿敏等级（MSL）处理，防潮包装与烘干可降低焊接缺陷。
- 0402 封装易受机械应力影响，贴装与波峰/回流时避免过大的顶压。
- 设计电路时加入适当限流与防静电措施，避免反向高压或瞬态损伤。
SMLP14BCNWT86 以其极小体积、稳定的蓝光输出和适中的光强，适合对空间与能耗敏感但仍需可见指示的电子产品。具体焊接参数与详尽电气图表请参考 ROHM 官方数据手册以获得最准确的工艺与可靠性指导。

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.
