MHS110UBCT(MEIHUA)蓝光SMD LED 产品概述

MHS110UBCT 是美华(MEIHUA)推出的一款小型侧贴式蓝光发光二极管,封装尺寸为 SMD 1.5 × 3.0 mm。该器件以窄体积、较宽的发光角和稳定的光学/电学特性,适用于各类面板指示、便携终端和一般照明/装饰类应用。下文从关键参数、封装与安装、典型电路建议、热与可靠性以及使用建议等方面进行简介,便于选型与工程应用。

一、主要电性与光学参数(概要)

  • 发光颜色:蓝色
  • 峰值波长:475 nm(波长范围 460–475 nm)
  • 正向电压 Vf:3.2 V(标称)
  • 正向电流 If:5 mA(推荐工作电流)
  • 功率(额定/散热限制):60 mW
  • 发光强度:112 mcd(在推荐 If 下的典型发光强度)
  • 发光角度:120°(广角出光)
  • 透镜颜色:无色透明(高透光,色散小)
  • 工作温度范围:-35 ℃ 至 +85 ℃

说明:上列参数为器件的典型/标称值,具体特性与波动请参考完整技术规格书或向厂家确认。

二、封装与机械特性

  • 封装形式:SMD(侧贴,载带方式为侧贴)
  • 尺寸:1.5 mm × 3.0 mm 小型封装,适合高密度贴片设计
  • 透镜:透明透镜设计有利于色彩保真与较大发散角(120°),可用于扩散与指示类用途
  • 推荐事项:由于器件尺寸小,建议按厂家提供的 PCB 焊盘尺寸和回流工艺布局,避免热应力与贴装偏差。有关极性、焊盘形状与焊盘尺寸请参见完整封装图。

三、典型驱动与限流设计

LED 必须使用限流方式驱动以保证稳定与寿命。根据给定 Vf = 3.2 V、If = 5 mA,可按下式快速计算系列限流电阻: R = (Vsup − Vf) / If

示例(取 Vf = 3.2 V,If = 5 mA):

  • 5 V 电源:R = (5 − 3.2) / 0.005 = 360 Ω,功耗 Pd = 1.8 V × 5 mA = 9 mW(普通 1/10 W 电阻足够)
  • 12 V 电源:R ≈ 1.76 kΩ,Pd ≈ 44 mW(推荐 1/4 W 电阻)
  • 24 V 电源:R ≈ 4.12 kΩ,Pd ≈ 104 mW(建议使用 1/4 W 或更高功率电阻或采用恒流驱动)
  • 3.3 V 电源:R ≈ 20 Ω,余压非常小,不建议直接用小阻值限流;更推荐使用恒流源或提高安全裕度。

建议:在电源波动大或多 LED 串并联时,优先选用恒流源驱动或单独限流电阻,并考虑器件与电阻的功率与散热余量。

四、热管理与可靠性注意

  • 最大工作温度 +85 ℃,环境温度升高会影响光强与寿命。建议在高温环境下适当降低 If 或采用间歇驱动以延长寿命。
  • 标称功率 60 mW 是器件整体热限制,实际正向功耗(Vf × If)在常规工作点远低于此限制,但应避免在高环境温度下长时间接近额定限制。
  • 贴装与回流焊时遵循一般 SMD LED 的温度曲线与清洗规范,避免长期受潮或超温回流导致透镜变形或光学衰减。
  • 采取常规防静电措施(ESD)与干燥保存以防损伤。

五、典型应用场景

  • 面板与状态指示(消费电子、仪表、家电指示灯)
  • 便携设备与穿戴电子(由于小尺寸便于集成)
  • 背光与装饰照明(小面积点光源、点阵显示)
  • 颜色效果或提示灯(配合驱动与控制实现闪烁/亮度可调)

六、选型与工程建议

  • 在最终量产前务必索取并验证厂家完整数据手册(包括 IV 曲线、光强分布曲线、焊盘尺寸图与回流曲线)以确认工程布局与性能裕度。
  • 为保证一致性,建议同批器件做光通量/色温分级或筛选(若对色彩一致性要求严格)。
  • 若项目对高亮度或长寿命有更高要求,可考虑降低 If 或选择规格更高的同色系 LED。

结语:MHS110UBCT 以小体积、宽发光角与稳定的蓝色特性适合多种指示与装饰场景;合理的限流与热管理是确保其长期稳定运行的关键。选型与批量设计时请结合完整数据手册与样件验证结果。

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
