MHT170RGBCT 0805 产品概述
一、产品简介
MHT170RGBCT 是美华（MEIHUA）推出的一款微型贴片RGB LED，封装规格为0805，采用共阳极设计。该器件以小体积、高集成度为特点，透镜为无色透明，光色纯净，适合对尺寸和色彩控制要求较高的消费电子与指示照明应用。
二、主要光学参数
- 波长范围（典型发射带宽）：R: 615–625 nm；G: 518–530 nm；B: 457–475 nm
- 峰值波长：R: 625–645 nm；G: 524–533 nm；B: 462–478 nm
- 发光强度（典型范围）：R: 100–210 mcd；G: 120–300 mcd；B: 34–85 mcd
- 发光角度：120° 这些参数决定了该LED在小角度与广角均可获得稳定的色彩表现，绿色亮度优势显著，适合需高绿光输出的显示或指示用途。
三、电气特性与功率
- 正向电流（If）：R: 20 mA；G: 5 mA；B: 5 mA（共阳极驱动时注意各通道电流差异）
- 正向压降（Vf）：R: 1.8–2.4 V；G: 2.8–3.4 V；B: 2.8–3.4 V
- 功率：G: 90 mW；R: 40 mW；B: 90 mW
- 载带方式：正贴（SMT） 设计驱动电路时应分别为各色通道配置限流电阻或恒流驱动，避免过流导致亮度不稳定或寿命下降。
四、封装与环境
- 封装：0805（适配常规贴片生产工艺）
- 透镜颜色：无色透明
- 工作温度：-30 ℃ 至 +85 ℃ 微型封装利于空间受限的设备使用，支持常规回流焊工艺，需要按厂家回流曲线控制温度，以保证可靠性。
五、应用建议与注意事项
- 典型应用：仪表背光、指示灯、微型显示点阵、可穿戴设备与精密仪器的状态指示。
- 驱动建议：由于红绿蓝三色额定电流差异较大（红色20mA，绿/蓝5mA），在共阳模式下建议对各色独立限流，并优先采用恒流源以保证色彩一致性与寿命稳定。
- 散热与可靠性：虽然单只功率不高，但在高占空比或多点并联时应注意PCB散热路径与焊盘设计，保证长期工作稳定。
- 选型提示：若系统对蓝光或绿光亮度有高需求，可依据发光强度范围选择合适批次；对色温/色域有严格要求时，建议索取样片进行光谱验证。
六、总结
MHT170RGBCT 0805 是一款适合空间受限、需多色指示与精细色彩控制的SMD RGB LED。其共阳极设计与小尺寸封装便于高速贴装与批量生产；不同色通道的电流与功率特性需在驱动电路设计时重点考虑，以实现稳定色彩输出与长期可靠性。若需更详细的光电曲线或回流焊建议，可向供应商获取完整数据手册与样品测试。

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.
