MHT192URCT 0603 红色发光二极管（MEIHUA 美华）产品概述
一 概述
MHT192URCT 是美华（MEIHUA）推出的一款超小型表面贴装红色发光二极管，封装为 0603，透明透镜设计，发光均匀、响应快，适合对体积和外观有严格要求的指示灯及背光应用。器件工艺稳定，适配自动化贴装和回流焊工艺。
二 主要参数
- 发光颜色：红色
- 正向压降 Vf：1.7 V ～ 2.1 V
- 额定功率：140 mW
- 正向电流 If：20 mA（推荐工作电流）
- 波长范围：617 nm ～ 625 nm；峰值波长约 630 nm
- 透镜颜色：无色透明
- 发光强度：900 mcd（典型值）
- 发光角度：120°
- 工作温度：-40 ℃ ～ +85 ℃
三 光电性能特点
该器件在推荐电流下可提供较高的亮度（典型 900 mcd），宽视角（120°）确保在较大观察角仍能保持可见性。红光波段光谱适用于指示与信号显示，透明透镜有助于光通量输出与颜色纯度的保持。
四 封装与机械特性
0603 封装尺寸小，利于高密度 SMT 布局。透明透镜利于光学一致性和可视效果。适合自动化贴片、回流焊接生产线，需按厂商推荐的回流温度曲线进行焊接。
五 工作环境与可靠性
器件可在 -40 ℃ 至 +85 ℃ 环境工作，适应一般工业与消费类应用。额定功率 140 mW 与最大正向电流 20 mA 表明在高电流、长期工作时需注意功耗及热量管理，建议在设计中预留裕量并做适当降额使用。
六 典型应用
- 面板指示灯与状态指示
- 仪表、家电和通信设备指示
- 可穿戴与便携设备微型指示灯
- 小型背光与符号照明
七 使用与设计建议
- 驱动：推荐恒流驱动，If 以 20 mA 为参考。限流电阻计算示例：R = (VCC − Vf)/If（取 Vf 典型值 1.9 V）。
- 焊接：遵循回流焊温度曲线，避免长时间超温以免影响光衰和可靠性。
- PCB 布局：为保证一致发光与散热，保持焊盘清洁，必要时在大电流密集区域考虑外延散热处理。
- 防护：建议 ESD 防护和在潮湿敏感元件管理下储存，以保证良率与长期可靠性。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
