MHT194CRGBCT 产品概述
一、产品简介
MHT194CRGBCT 是美华（MEIHUA）推出的一款高亮度、共阳极（Common Anode）RGB SMD 发光二极管，封装规格为 0606（1.6 × 1.5 × 0.6 mm），无色透明透镜，发光角度 130°。器件体积小、视角宽、色彩纯度高，适用于微型指示、背光、可穿戴设备和狭小空间的多色指示应用。
二、主要电气与光学参数
- 驱动配置：共阳极（单端阳极，三路共用阳极引脚，单独控制各色阴极）
- 推荐正向电流：R：20 mA，G：20 mA，B：20 mA
- 峰值正向功率：G：95 mW；B：95 mW；R：60 mW
- 峰值波长：R 632 nm；G 528 nm；B 470 nm
- 发射波段：R ~623 nm（名义）；G 520–530 nm；B 465–475 nm
- 正向压降（Vf）：R 1.7–2.4 V；G 2.7–3.3 V；B 2.7–3.3 V
- 发光强度（Iv）：G 450–1120 mcd；R 112–285 mcd；B 112–285 mcd
- 工作温度范围：-40 ℃ ～ +85 ℃
三、结构与封装
- 封装型号：0606 SMD（1.6 mm × 1.5 mm × 高 0.6 mm）
- 透镜：无色透明，利于色彩混合与均匀出光
- 发光角度：130°，适合大角度观看与均匀照明需求
四、使用建议与典型电路
- 共阳极驱动：将阳极连接到稳定电源（Vcc），通过低电平或开路控制各色阴极（NPN/场效应管或 MCU 输出经限流电阻下拉）。
- 限流电阻计算：R = (Vcc - Vf) / If（例：Vcc=5V，绿色 Vf≈3.0V，If=20mA → R≈100 Ω）
- 注意不要超过额定正向功率与电流，长时间高电流会导致亮度衰减或寿命降低。建议在设计中留有热裕量并采用恒流驱动以获得最佳一致性。
五、可靠性与注意事项
- 对静电敏感，建议在生产与装配过程中采取 ESD 防护措施。
- 推荐采用符合 JEDEC/IPC 的回流焊工艺，参考供应商给出的温度曲线以避免过热。
- 存储与使用环境避免长时间高温、高湿，超出工作温度或超过最大正向功率会加速光衰和降低器件寿命。
六、典型应用场景
- 面板指示、状态指示灯、信号灯
- 微型显示与图形指示（如智能穿戴、耳机指示灯）
- 仪器仪表、消费电子、物联网终端的多色指示与背光
总结：MHT194CRGBCT 以微型化封装、宽视角和较高亮度为优势，尤其适合对体积、外观及多色显示有严格要求的场合。合理的驱动与热管理可确保器件稳定工作并延长使用寿命。

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.
