MHS190UBCT(0603)蓝光LED 产品概述

一、概述

MHS190UBCT 是美华(MEIHUA)推出的一款小尺寸高可靠蓝光发光二极管(LED),封装为 SMD 0603(0.6 × 1.6 mm),专为体积受限的指示、背光和便携设备设计。该器件峰值波长 468 nm,发光色为纯正蓝色,具有大约 120° 的宽视角和透明无色透镜,提供均匀且可视性良好的光输出。典型工作电流较小(5 mA),适合低功耗应用与自动化贴装生产线(载带方式:侧贴)。

二、主要电气与光学参数

  • 发光颜色:蓝色
  • 峰值波长:468 nm(光谱范围 460–475 nm)
  • 正向电压(Vf):2.7 V ~ 3.2 V
  • 额定正向电流:If = 5 mA(典型)
  • 发光强度:72 mcd(标称,通常在 If=5 mA 时测量)
  • 发光角度:120°(半值角,大视角,便于视觉覆盖)
  • 透镜颜色:无色透明(高透光率)
  • 功率:95 mW(按厂家规格)
  • 工作温度范围:-35 ℃ ~ +85 ℃

(注:实际光强和色坐标会随正向电流、温度与换算条件变化,设计时建议参照完整数据手册。)

三、封装与机械特性

  • 封装类型:SMD,0603(0.6 × 1.6 mm)极小体积,适合高密度 PCB 布局。
  • 载带方式:侧贴(便于贴片机自动化取放)。
  • 透镜:透明无色透镜设计,发光更均匀、色偏小。
  • 建议在 PCB 设计时采用与器件实际脚座匹配的焊盘尺寸,并参考厂商推荐焊盘与回流工艺文件以保证焊接一致性与可靠性。

四、驱动与电路建议

  • 常用驱动方式:恒流驱动最佳,保证恒定光强与颜色稳定;若使用限流电阻,可按公式计算:R = (Vs - Vf) / If。
  • 典型限流电阻举例(取 Vf=2.9 V 近似中值,If=5 mA):
    • Vs = 5 V:R ≈ (5 - 2.9) / 0.005 = 420 Ω → 推荐 430 Ω
    • Vs = 3.3 V:R ≈ (3.3 - 2.9) / 0.005 = 80 Ω → 推荐 82 Ω
    • 功率:电阻耗散 P = I^2 · R,5 mA 时功耗极小(例如 430 Ω 下约 0.0108 W),普通 1/8W~1/4W 电阻即可。
  • 如果需要更高精度或多颗串并联驱动,建议采用恒流源或 LED 驱动 IC,以减小光输出差异并提高可靠性。

五、热与可靠性注意事项

  • 器件工作温度范围 -35 ℃ ~ +85 ℃,设计时需考虑环境温升与 PCB 热阻。
  • 在高温或长时间大电流工作下,LED 光通量会随温度衰减,建议在出厂额定电流下使用并留有余量以延长寿命。
  • 避免在超过额定回流温度或长时间潮湿环境中直接暴露,生产过程中应采取防潮与防静电(ESD)措施。

六、焊接与存储建议

  • 推荐采用无铅回流焊工艺,遵循厂商推荐的温度曲线(典型 SMD LED 的峰值温度 ≤ 260 ℃,具体请参照数据手册)。
  • 存储时避免高温高湿,未开封产品按防潮包装存放;开封后若超过厂商建议的曝露时间,应进行干燥处理(烘烤)再进行贴装。
  • 操作时注意 ESD 防护(佩戴接地腕带,使用防静电工作台),以免损伤 LED 芯片。

七、典型应用场景

  • 指示灯与状态指示(仪器、家电、通信设备)
  • 面板与按键背光(薄型电子设备)
  • 可穿戴设备与移动终端(体积小、低功耗)
  • 工业控制与医疗设备的状态显示
  • 光学传感器中的光源(需参考光谱匹配)

八、采购与标识

  • 型号:MHS190UBCT
  • 品牌:MEIHUA(美华)
  • 封装:SMD 0603(0.6 × 1.6 mm)
  • 订购时请确认需求参数(波长区间、光强、载带方向、封装批次等),并索取完整数据手册与曲线数据以进行精准设计验证。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
