MHT194CRCGCT 产品概述
一、产品简介
MHT194CRCGCT 是美华（MEIHUA）推出的一款小型0606贴片发光二极管，提供红色与黄绿色两种发光颜色。该器件在典型工作电流 5mA 时表现出稳定的光学和电气特性，适用于指示、背光、按键、仪表面板等多种低功耗照明与指示场景。
二、主要电气与光学参数
- 正向电流（If）：5 mA（额定典型值）
- 峰值波长（黄绿色 / 红色）：574 nm（黄绿色，光谱范围 567.5–575.5 nm） / 638 nm（红色，典型 631 nm）
- 正向压降（Vf）：1.6 V ～ 2.1 V（随颜色与工作电流略有变化）
- 发光强度（Iv，@5mA）：黄绿色约 38 mcd；红色约 18 mcd
- 发光角度：130°（宽视角，适合大面积均匀指示）
- 最大功率耗散：60 mW（器件总功率限制）
- 工作温度范围：-40 °C ～ +85 °C
- 透镜颜色：无色透明透镜（光色保真、色散小）
- 封装：0606 小型贴片封装，适合自动贴装与回流焊工艺
三、应用场景
- 仪表面板与状态指示灯（工业设备、消费电子）
- 键盘/按键背光与功能指示
- 线路板指示与信号提示（低功耗场合）
- 小型照明点缀与装饰光源
四、使用建议与驱动参考
- 驱动方式：建议恒流驱动，额定驱动电流 5 mA 可获得稳定亮度与长寿命。
- 限流电阻计算：R = (Vs - Vf) / If。示例：若供电 5 V，取 Vf ≈ 2.0 V，If = 5 mA，则 R ≈ (5 - 2.0) / 0.005 = 600 Ω，常用阻值 620 Ω。
- PWM 调光：支持 PWM 调光以实现亮度控制，频率应高于人眼可察觉范围（>200 Hz）以避免闪烁。
- 热管理：单只 LED 功耗低，但在多颗并列或较高占空比下应注意 PCB 散热以及工作环境温度，避免接近上限 85 °C。
- 焊接与组装：采用常规 SMD 回流焊工艺，遵循制造商的焊接温度曲线与 PCB 设计建议，避免长时间高温暴露影响封装与光通。
五、可靠性与存储
- 存储环境建议避免潮湿、高温与强光照射，长期存放建议防潮包装并在规定时间内回流焊接。
- 工作环境：可在工业级温度范围内稳定工作（-40 °C ～ +85 °C），适合室外或恶劣环境的指示应用，但在高湿度或化学腐蚀环境需采取防护措施。
总结：MHT194CRCGCT 以小型 0606 封装、宽视角与低功耗为特点，黄绿色（574 nm）与红色（≈631–638 nm）两色可选，典型工作电流 5 mA、正向压降 1.6–2.1 V，适用于各类指示与背光应用。针对具体电路与工艺建议参照供应商的详细数据手册与回流焊规范进行设计与装配。若需更详细的光电特性曲线或封装尺寸图，我可继续提供。

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.
