MHT193UBCT（0603）产品概述
一、产品简介
MHT193UBCT 是MEIHUA（美华）出品的0603封装蓝色发光二极管（LED），中心波长约470nm，透镜为无色透明，视角宽达130°。典型工作电流为3mA、发光强度约18mcd，工作温度范围-40℃至+85℃，正向压降(Vf)典型值2.96V，额定功率100mW。体积小、亮度稳定，适合对尺寸和能耗有严格限制的移动与可穿戴终端及指示类用途。
二、主要特性
- 尺寸：0603（小型SMD，适合集成化设计）
- 发光颜色：蓝色（470nm）
- 视角：130°（宽视角、均匀可见）
- 典型亮度：18mcd（在3mA条件下）
- 正向电流：3mA（典型工作点）
- 正向压降：2.96V（典型）
- 工作温度：-40℃ ~ +85℃
- 透镜：无色透明，保证色纯和光学一致性
三、典型应用
适用于指示灯、仪表面板、按键背光、移动设备与可穿戴设备指示、物联网传感器、医疗仪器与小型显示背景照明等需要小型低功耗、宽视角蓝光的场景。
四、设计与使用建议
- 限流电阻计算：R = (Vcc - Vf) / If。例：3.3V供电时，R ≈ (3.3-2.96)/0.003 ≈ 113Ω，建议取120Ω；5V供电时R ≈ 680Ω。
- 功耗与散热：按3mA工作时器件自身耗散约2.96V×3mA ≈ 8.9mW，远低于100mW极限，但长期高温会影响光衰，应避免超过推荐温度并优化散热路径。
- PCB布局：0603封装对焊盘尺寸与锡膏量敏感，建议参考制造商推荐PCB焊盘与回流焊工艺参数，避免一侧过多锡导致偏位。
- 静电与搬运：LED对ESD敏感，装配与测试时请佩带接地腕带并保持防静电作业环境。
五、焊接与储存
- 推荐采用标准SMT回流焊流程，并严格控制回流温度曲线（遵循制造商回流建议）。
- 储存应避免高湿与极端温度，长期存放请按干燥包装条件保管或做防潮处理，开封后尽快使用或放入干燥箱。
六、可靠性与选型提醒
- LED寿命与光衰受电流、温度与驱动方式影响，低电流驱动与良好散热可显著延长使用寿命。
- 如需更多绝对最大额定值（如最大正向电流、反向电压、回流焊峰值温度等）与典型光电曲线，请参照厂商正式数据手册或联系供应商获取详细规格与可靠性测试报告。
如需我为您生成典型电路示意、推荐PCB焊盘尺寸或提供与该型号相近的替代型号对比表，可继续说明用途与供电条件。

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.
