MHL5013UBTD(MEIHUA 美华)5mm 蓝光 LED — 产品概述

一、产品简介

MHL5013UBTD 是美华(MEIHUA)出品的一款高亮度 5mm 插件蓝色发光二极管(LED),灯头为圆形透镜。该器件在典型驱动条件下提供稳定的蓝色光输出,适合指示、显示和一般照明点光源场合。结构为插件(THT)封装,便于面板安装与手工或波峰焊接。

二、主要性能参数

  • 型号:MHL5013UBTD
  • 封装:插件,D = 5mm 圆头
  • 发光颜色:蓝色
  • 波长(近似):468 nm(峰值波长 470 nm)
  • 发光角度:60°(中窄角,光束集中)
  • 典型光强(Iv):390 mcd(IF = 20 mA)
  • 正向电流(IF):典型 20 mA(标称工作电流)
  • 额定功率/最大耗散功率:120 mW(封装最大耗散能力)
  • 正向压降(Vf):约 3.2 V(在 IF = 20 mA 时典型值)
  • 工作温度范围:-25 ℃ ~ +85 ℃

三、电学与光学说明(含示例计算)

  • 电功率耗散:在标称工作点 IF = 20 mA、Vf ≈ 3.2 V 时,器件耗散功率约为 P = Vf × IF = 3.2 V × 0.02 A = 0.064 W(64 mW),远低于额定 120 mW,说明正常工作有一定热裕量,但应注意环境温度与散热条件影响。
  • 波长与颜色:厂家给出的典型波长约 468 nm,峰值 470 nm,两者差异很小,呈典型的蓝色视觉效果。波长与视觉感知、光谱应用相关,选择时可与系统光谱需求比对。
  • 光束与应用:60° 发光角度属于中窄束范畴,适用于点状指示或需集中光斑的场景;若需更宽散射,应配合扩散透镜或使用广角封装器件。

示例限流电阻计算(常见电源):

  • 5 V 电源:R = (5 V − 3.2 V) / 0.02 A = 90 Ω → 取标准值 100 Ω(0.25 W 或更高功率等级)
  • 12 V 电源:R = (12 V − 3.2 V) / 0.02 A = 440 Ω → 取 470 Ω

建议在设计中预留一定裕量,或采用恒流源驱动以保证亮度一致性与长寿命。

四、使用与安装建议

  • 插件安装:长脚为阳极(请依据实际样品确认),安装时注意极性,反向施加电压可能损坏器件。
  • 焊接工艺建议:手工焊接建议焊接点温度与时间控制以避免过热损伤(例如焊接温度不宜过高、单点焊接时间尽量控制在数秒内)。波峰焊或回流过程应遵循一般 LED 的温度-时间限制,并在工艺前与供应商确认具体参数。
  • 散热与环境:虽然单颗 5mm LED 功耗不高,但在高环境温或密集排列时需注意散热与热累积,避免长期在接近 +85 ℃ 环境下高电流工作。
  • ESD 防护:蓝色 LED 对静电敏感,建议在装配与测试过程中采取防静电措施(接地手环、防静电台面等)。

五、典型应用场景

  • 面板与设备状态指示灯(电源、工作指示等)
  • 消费电子与仪器设备的功能指示
  • 仪表、医疗设备的指示与信号反馈
  • 小型发光装饰、示范灯及光源模块
  • 需要中等聚光效果的点光源场合

六、注意事项与可靠性建议

  • 工作电流与温度成正相关关系:长时间在高温下以额定电流工作会加速衰减,应在热设计中考虑电流降额或散热强化。
  • 反向电压限制:避免对 LED 施加高于其反向耐压的电压,防止击穿。具体反向耐压值请参见完整规格书或向供应商确认。
  • 存储与运输:避免高温高湿环境,长期储存建议干燥、防潮、防尘。开盘后若包装含干燥剂,应按建议时间内使用或回烘以保证焊接可靠性。
  • 质量与一致性:若用于颜色要求严格的显示系统,建议批次间进行颜色与光强匹配筛选(binning)。

总结:MHL5013UBTD 为一款性能稳定的 5mm 蓝光插件 LED,典型电流 20 mA 下提供约 390 mcd 的亮度与 60° 的中窄发光角,适合多种指示与点光源应用。设计时关注限流、散热与静电防护,可获得长期可靠的使用表现。若需完整电、光学曲线和严格的焊接参数,建议参考供应商的详细数据手册或直接咨询美华技术支持。

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.
