MHT193CRCT 0603 产品概述
一、产品简介
MHT193CRCT 为美华（MEIHUA）生产的 0603 封装红色表面贴装发光二极管（LED）。器件发射纯红光，峰值波长 631 nm，适合高密度 PCB 装配与指示、背光等小功率照明场景。正贴设计便于自动贴片和回流焊工艺。
二、关键规格
- 型号：MHT193CRCT（0603）
- 发光颜色：红色；波长（λp）：631 nm
- 正向电压 Vf：2.2 V（典型）
- 正向电流 If：5 mA（额定）
- 功率耗散：75 mW
- 发光强度：28 mcd（测试条件下）
- 发光角度：130°（半值角）
- 透镜：无色透明
- 工作温度：-40 ℃ ~ +85 ℃
- 载带方式：正贴（SMD）
三、主要性能与优势
- 小尺寸（0603）占板面积小，适合紧凑布局。
- 宽视角（130°）提供均匀可视效果，适用于指示灯与面板背光。
- 低功耗设计（典型 If 5 mA，功率 75 mW）利于电源管理与热控。
- 透明透镜有利于光学一致性与配光控制。
四、封装与安装建议
- 建议采用常规 SMD 回流焊工艺，遵循 J-STD-020 推荐回流曲线，峰值温度不超过 260 ℃。
- 焊盘设计按 0603 标准尺寸并留有焊膏扩展，避免过量焊膏造成短路或浮焊。
- 常规表面贴装贴片机与回流线兼容，适合自动化生产。
- 装配时注意极性标识（阴极/阳极）以避免误焊。
五、典型电路与应用
- 驱动：常用限流电阻串联驱动。示例（5 V 电源）：R = (VCC − Vf) / If = (5.0 − 2.2) / 5 mA ≈ 560 Ω（取标准阻值 560 Ω）。
- 应用场景：面板指示、仪表指示灯、背光点阵、小型信号指示等低功率照明场合。
六、选型与可靠性注意事项
- 若需更高亮度或更大电流，请选用额定 If 更高或更大封装的型号，并注意功率与散热。
- 遵守最大功率 75 mW 和工作温度范围以免加速老化或损坏。
- 存储与贴装前应注意防潮处理，长期库存建议密封防潮包装并回潮焊处理（如适用）。
- 生产与维修过程中注意 ESD 防护，避免静电击穿。
如需整机配光数据、回流焊曲线或贴片尺寸图纸，可进一步提供以便给出更详细的生产与光学设计建议。

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.
