MHT136CRCT（0402）红色贴片LED 产品概述
一、产品简介
MHT136CRCT 是美华（MEIHUA）推出的一款微小型0402封装红色发光二极管，峰值波长约632nm，外观为无色透明透镜，发散角大（120°），适用于对尺寸和视角有要求的表面贴装指示与照明场合。该器件以小体积、稳定的光学性能和宽工作温度而著称。
二、主要性能指标
- 发光颜色：红色，峰值波长：632nm（范围 617.5nm–633.5nm）
- 正向电压（Vf）：典型 1.9V
- 正向电流（If）：推荐 5mA（额定功率 60mW）
- 发光强度：36 mcd（典型，通常在额定测试条件下测得）
- 发光角度：120°（广角，适合面光源或指示灯）
- 工作温度范围：-35°C 至 +85°C
- 封装：0402 表面贴装
三、电气与驱动建议
- 驱动原则：采用恒流源驱动可获得稳定亮度；若采用限流电阻，计算公式为 R = (Vcc − Vf) / If。
- 示例（以 Vf=1.9V、If=5mA 为基准）：
- 5V 系统：R ≈ (5.0 − 1.9) / 0.005 = 620Ω，常选 620Ω 或保守取 680Ω；
- 3.3V 系统：R ≈ (3.3 − 1.9) / 0.005 = 280Ω，常选 270Ω 或保守取 330Ω。
- 功率考虑：在 If=5mA 时，二极管自身功耗约为 Vf×If ≈ 9.5mW，远低于标称60mW额定，仍应注意整体PCB热管理与周围器件影响。
四、热与环境特性
器件工作温度覆盖-35°C至+85°C，适合多数室内与部分户外低温应用。高温环境下应关注驱动电流与散热条件，以避免长期老化导致光衰。
五、封装与机械特性
0402超小封装非常适合高密度贴片布局，兼容常规贴片机与回流焊工艺。透镜为无色透明，出光均匀。建议在PCB设计时留出适当焊盘尺寸并考虑焊膏量以保证焊接可靠性。
六、典型应用场景
- 工业与消费类设备面板指示灯
- 手持设备与可穿戴电子状态指示
- 精细电子产品的局部照明或光学标识
- 背光点阵、键盘指示、信号提示等
七、使用与储存建议
- 贴片与回流：建议按行业通用SMD回流工艺，遵循厂家回流温度曲线与最大温度限制。
- 防静电与防潮：在贴装与测试过程中注意ESD保护；若供应为封装托盘或管装，长时间储存建议防潮包装并按吸湿敏感等级处理（若需具体MSL等级，请咨询供应商数据表）。
- 测试与验收：在最终产品中应以实际工作电流和环境温度为准进行光学与电气验证，避免超额驱动导致寿命下降。
八、订购与注意事项
选型时请确认所购批次的光电参数和包装形式（卷带、盘装等），如需更详细的IV曲线、光谱分布或回流曲线，请向MEIHUA或授权经销商索取完整数据手册。本产品适合追求小尺寸与红色均匀照明的工程应用。

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.
