MHT150RBCT — 1206 正贴红蓝双色 LED 产品概述
一、产品简介
MHT150RBCT 是美华（MEIHUA）推出的 1206 封装正贴式红/蓝双色发光二极管，采用透明无色透镜设计，体积小、光学一致性好，适合批量贴装与表面贴装（SMT）生产。器件可在单一封装内实现红、蓝两色显示，便于状态指示与色彩切换设计。
二、主要参数
- 正向电流（If）：20 mA（典型驱动电流）
- 峰值波长：红色 632 nm（标称 621 nm）；蓝色 462 nm（标称范围 460–475 nm）
- 正向压降（Vf）：红色 1.8–2.5 V；蓝色 2.7–3.4 V
- 发光强度：360 mcd（典型）
- 功率：60 mW / 90 mW（型号或工作点相关）
- 发光角度：130°（典型）
- 工作温度：-40 ℃ ～ +85 ℃
- 封装：1206 SMD，透明无色透镜
三、电气与光学使用建议
- 驱动方式：建议恒流驱动或在限流电阻保护下由 MCU/PWM 控制以实现调光与颜色混合。最大推荐连续正向电流为 20 mA，短时脉冲可提高瞬时亮度但需控制平均功率。
- 限流电阻计算公式：R = (Vsup − Vf) / I。示例（以 I=20 mA）：5 V 供电时红色（取 Vf≈2.0 V），R ≈ (5−2.0)/0.02 = 150 Ω；蓝色（取 Vf≈3.0 V），R ≈ (5−3.0)/0.02 = 100 Ω。实际选值应考虑 Vf 范围与容差。
- 热管理：1206 为小型封装，热阻较高，长时间高电流工作或高占空比会导致结温上升，建议优化 PCB 散热铜箔面积并控制驱动电流与占空比。
- 光学布局：130° 的大视角适合广角指示与均匀背光，透镜透明有助于颜色纯度，但在光学隔离场景下需配合遮光结构使用。
四、典型应用
- 面板指示灯、状态指示（工作/报警/待机）
- 消费电子、家用电器面板、遥控器指示
- 物联网终端与嵌入式设备状态反馈
- 仪表、测试设备指示与信号提示
五、封装与生产注意事项
- 封装类型为 1206 SMD，适用于自动贴片与回流焊工艺。建议按厂家数据手册采用规定的焊盘尺寸与回流温度曲线。
- 产线操作注意 ESD 防护与防潮储存，避免高温/潮湿环境影响焊接与光学性能。
- 选型时确认器件内部是共阴或共阳以及引脚定义，避免在电路设计中接反导致无法正常切换颜色。
若需进一步的电气特性曲线、外形尺寸图或回流曲线，请联系 MEIHUA（美华）获取完整数据手册与元件抽样信息，以便在设计与量产中达到最佳性能与可靠性。

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.
