MHT151CRCT 产品概述
一、产品简介
MHT151CRCT 为 MEIHUA（美华）出品的红色发光二极管，采用1206贴片封装，反贴载带设计，适用于自动贴装生产线。发光颜色为纯红，峰值波长632 nm，视觉上呈现标准红色指示效果，适合各种状态指示与面板照明场景。
二、主要电光参数
- 发光颜色：红色
- 峰值波长：632 nm；波长范围：617.5 nm ~ 633.5 nm
- 正向电压（Vf）：1.75 V ~ 2.35 V
- 额定正向电流（If）：5 mA（典型驱动）
- 最大功率耗散：60 mW（器件最大允许功率）
- 发光强度：57 mcd（在标称测试条件下）
- 发光角度：130°（广角出光）
- 透镜：无色透明透镜
- 工作温度范围：-40 ℃ ~ +85 ℃
说明：在 If=5 mA 时，器件实际耗散功率约为 Vf×If（约 8.75–11.75 mW），60 mW 为器件绝对最大功率限制，应避免长期接近该极限。
三、外观与封装
封装形式为1206贴片（常用于 PCB 指示灯位），透镜为无色透明，出光均匀且颜色真实。载带方式为反贴（反向贴装），便于标准 SMT 生产线的取料与贴装定位。具体外形尺寸、焊盘布局请参照厂家数据资料，便于可靠焊接与热管理设计。
四、典型应用场景
- 仪器面板与状态指示灯
- 通信设备与路由器指示
- 家用电器与消费电子状态提示
- 工业控制、测试设备信号显示
- 交通与安防类指示（在符合温度与认证要求下）
五、设计与使用建议
- 驱动设计：建议恒流驱动或串联限流电阻。举例，若以 5V 电源和 Vf≈2.0V、If=5mA 计算，限流电阻约为 (5-2.0)/0.005 ≈ 600Ω，可选择标准阻值 620Ω。
- 热管理：尽量在推荐的工作电流范围内使用，避免超过额定功率，PCB 铜箔及散热设计有助于延长寿命。
- 焊接工艺：采用标准 SMT 回流工艺，遵循厂家推荐的回流曲线与 IPC/JEDEC 焊接规范，避免长时间高温暴露。
- ESD 与静电防护：在装配与测试过程中注意静电防护，防止击穿器件。
六、储存与可靠性
建议密封干燥包装存放，避免潮气、强光与高温环境。长期储存前应遵循防潮包装要求并在可能情况下进行必要的烘烤处理（按厂家说明）。在-40 ℃至+85 ℃的工作温区内可正常工作，但在极端或反复热循环环境下应进行可靠性验证。
总结：MHT151CRCT 是一款适用于批量自动贴装的1206红色LED，具有色纯、亮度稳定、宽视角的特点，适合多种指示与状态显示用途。选择与设计时请结合实际工作电流、散热条件与焊接工艺，参考厂商完整技术资料以获得最佳可靠性。

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.
