MHT193UGCT（0603）翠绿色贴片发光二极管 产品概述
一、产品简介
MHT193UGCT 为美华（MEIHUA）出品的 0603 封装翠绿色发光二极管（LED），透镜为无色透明，发光波长约 530nm，呈鲜明翠绿色。该器件设计用于小型化、低功耗的指示与背光场合，在紧凑 PCB 布局与移动电子产品中具有良好适配性。
二、主要电光参数
- 发光颜色：翠绿色（λpeak ≈ 530nm）
- 正向电压（Vf）：3.3V（典型）
- 正向电流（If）：5mA（工作电流）
- 最大功率：100mW（器件功耗额定）
- 发光强度：约 71mcd（典型，驱动条件 5mA）
- 发光角度：130°（宽视角）
- 工作温度：-40℃ ~ +85℃
三、封装与机械特性
0603 表示超小型贴片封装，典型尺寸约 1.6mm × 0.8mm（请以厂家数据为准）。无色透明透镜利于颜色纯度与亮度表现，适合表面贴装工艺（SMT），支持自动贴片与回流焊。
四、电气与光学设计要点
- 功耗评估：在推荐 If=5mA 时，器件耗散功率约 P=Vf×If=3.3V×5mA=16.5mW，远低于额定 100mW，工作余量充足。
- 限流设计：建议串联限流电阻或恒流驱动，计算公式 R=(Vs−Vf)/If。示例：若供电 5V，R=(5−3.3)/0.005≈340Ω，可选 330Ω 或 360Ω 标准值。
- 光学布局：宽视角 130° 适合指示与面板均匀照明，若需汇聚光束或提高定向照度，可配合小型遮光或透镜结构设计。
五、典型应用
- 消费电子状态指示灯（手机配件、遥控器、穿戴设备）
- 小尺寸面板与键盘背光
- IoT 终端与指示模块
- 仪器仪表与嵌入式系统状态提示
六、装配与使用注意事项
- 遵循厂家推荐回流焊曲线与 PCB 焊盘设计，避免长时间高温暴露。
- 小封装对贴装精度要求高，注意锡膏量与焊盘设计以防桥连或虚焊。
- 建议采取静电防护措施（ESD），并在存储中控制湿度，避免潮湿导致回流时爆裂。
- 在特殊应用（高环境温、连续高亮）下，应评估热管理与寿命影响。
七、可靠性与环境适应
工作温度范围宽（-40℃ 至 +85℃），适应多数工业与民用场景。实际应用中应结合真实工作电流、占空比与热环境验证光衰与可靠性，必要时与供应商确认完整的可靠性与光学老化数据。
总结：MHT193UGCT（0603）以其小体积、低功耗、宽视角与翠绿色高显色性，适合对空间与能耗有严格要求的指示与照明应用。设计时重点关注限流、贴装工艺与热管理，可在多类消费与工业场景中稳定发挥。

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.
