MHT151UBCT（1206）产品概述
一、概览
MHT151UBCT 是美华（MEIHUA）推出的一款1206封装蓝光发光二极管，透镜为无色透明，发光颜色为蓝色，峰值波长468nm（工作波段460–475nm）。该器件面向通用指示、背光及小型显示应用，采用反贴载带（逆向卷装）便于SMT贴装。
二、主要电光参数
- 正向电流（IF）：20mA（典型工作电流）
- 正向压降（Vf）：2.75V ~ 3.655V（随电流与温度变化）
- 发光强度：285mcd（IF = 20mA）
- 发光角度：130°（宽视角，适合均匀照明）
- 峰值波长：468nm
- 额定工作温度：-40℃ ~ +85℃
三、功耗与热管理
器件在工作时的电耗约等于Vf×IF（典型范围约55mW~73mW）；表中给出95mW应理解为器件允许的功耗等级或散热限制，应以完整规格书的最大额定功耗为准。设计时注意良好PCB散热、避免长期过流或高温回流。
四、安装与驱动建议
- 驱动方式：建议恒流驱动或在串联限流电阻的恒压驱动下工作。
- 电阻计算示例：VCC=5V，取Vf≈3.2V，R=(5−3.2)/0.02≈90Ω（取标准值91Ω）；VCC=3.3V时，若Vf接近3.65V则无法充分点亮，需采用升压或恒流源。
- 贴装：1206 SMT 封装，按常规无铅回流工艺，遵循JEDEC/IPC回流曲线；避免重复高温回流。
五、可靠性与注意事项
- 器件属静电敏感元件，生产与测试环节须做好ESD防护。
- 存储、运输避免潮湿，长期存放建议密封干燥箱或按厂家干燥储存要求处理。
- 上电前确认极性，避免反向过压。为延长寿命，尽量在额定电流或以下使用并控制结温。
六、典型应用
- 面板与按键指示灯、信号指示、状态显示
- 小型背光、手持设备指示
- 消费电子与工业设备的视觉提示
备注：以上为产品概述与典型设计建议，具体的最大额定值、回流曲线、老化与可靠性测试数据请参照厂家完整Datasheet或向供应商索取技术支持。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
