MHT150CRCT（1206）红色发光二极管 产品概述
一、主要参数
MHT150CRCT 是美华（MEIHUA）推出的一款1206贴片红色发光二极管（LED）。主要电光参数如下：
- 峰值波长：632 nm，波长范围：617.5 nm ~ 633.5 nm
- 正向电流（IF）：20 mA（典型工作电流）
- 发光强度：约 140 mcd（在额定条件下）
- 发光角度：130°（广角出光）
- 正向压降（Vf）：1.75 V ~ 2.35 V（随电流与工差变化）
- 最大功率耗散：95 mW（器件散热限制）
- 工作温度：-40 ℃ ~ +85 ℃
- 透镜颜色：无色透明透镜，发光颜色：红色
- 封装：1206 SMD
二、产品特性
- 宽视角（130°）便于可视范围广的指示与状态显示；
- 透明透镜提供纯净色调与较好的光学一致性；
- 1206小尺寸封装适合高密度PCB布局与自动贴装生产；
- 低电压驱动、能耗低，适用于电池供电设备与便携终端。
三、典型电气与光学建议
- 建议工作电流：常规使用20 mA；为延长寿命与降低发热，可采用10–15 mA 作为节能模式。
- 电阻选型示例（以恒流限流电阻为例）：
- 5 V 系统：R = (5 V − 2.0 V) / 20 mA ≈ 150 Ω（取标准值150 Ω）
- 3.3 V 系统：R = (3.3 V − 2.0 V) / 20 mA ≈ 65 Ω（可选68 Ω）
- PWM 调光：支持高频 PWM 调光以获得线性亮度控制，频率建议大于200 Hz 以避免可见闪烁。
- 功率与热管理：在20 mA 下，器件实际功耗通常小于规格功率上限，仍需保证PCB散热路径与环境温度控制。
四、典型应用
- 面板与设备指示灯、状态与告警显示
- 消费电子与家用电器的信号指示
- 仪表、开关与工业控制面板的视觉提示
- 小面积背光与装饰照明
五、封装与焊接建议
- 适合回流焊工艺，建议遵循制造商回流温度曲线（尽量控制峰值温度和保温时间以保护LED芯片与封装）。
- PCB焊盘设计应兼顾机械与热性能，常见1206封装遵循厂商推荐焊盘尺寸可提高贴装良率。
- 建议使用无卤无清洗（No-clean）助焊剂，若需清洗请确认所用溶剂对LED封装无侵蚀。
六、使用注意事项与可靠性
- 禁止超过最大正向电流与功率耗散，避免长期高温工作导致光衰加速；
- 注意ESD 防护，储存与装配过程中佩戴防静电设备；
- 存储环境建议干燥、防潮，避免高温高湿引起封装变色或性能退化；
- 如需脉冲高流驱动，须评估峰值电流、占空比与热循环对寿命的影响。
如需器件封装图、推荐焊盘尺寸、详细光电曲线或可靠性测试数据，可提供更具体要求后补充资料。

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.
