MHL3014URTD 产品概述

一、产品简介

MHL3014URTD 是 MEIHUA(美华)推出的一款高亮红色发光二极管(LED),采用插件式 3mm 圆头封装,型号标识为 LED_D3X5.38MM_TM。该器件面向指示照明和信号显示应用,具有小体积、低功耗、显色稳定等特点,适合消费电子、仪表盘、控制面板及通用指示场合。

二、主要参数

  • 发光颜色:红色
  • 波长(Dominant):642 nm
  • 峰值波长(Peak):660 nm
  • 正向电流(If):20 mA(额定)
  • 正向压降(Vf):约 1.8 V
  • 最大耗散功率:60 mW
  • 发光强度(Iv):200 mcd(典型值,If=20 mA)
  • 发光角度:30°(窄光束,方向性好)
  • 工作温度:-25 ℃ ~ +85 ℃
  • 封装形式:插件(Through-hole),灯头直径 3 mm

三、特点与优势

  • 高显色、红色饱和度好,视觉指示效果明显;
  • 窄发光角度(30°),适合需要准直或点状指示的场合;
  • 低正向压降与低功耗设计,单只功耗在额定条件下约 36 mW(1.8 V × 20 mA),远低于最大耗散 60 mW;
  • 插件式 3mm 小体积封装,便于手工或波峰/回流焊装配;
  • 宽工作温度范围,环境适应性强。

四、典型应用

  • 操作面板指示灯、状态指示灯;
  • 家用电器和消费电子产品的电源/状态指示;
  • 工业仪表、仪表盘及交通信号指示(非高功率外部信号);
  • 教育、DIY 与原型开发项目。

五、使用建议与电路注意事项

  • 驱动方式:推荐恒流驱动或在串联外接限流电阻使用。限流电阻可按公式计算:R = (Vsup − Vf) / If。
    • 例如 5 V 电源:R = (5 − 1.8) / 0.02 ≈ 160 Ω,可选标准值 150 Ω 或 180 Ω。
    • 例如 12 V 电源(单个 LED 不建议直接接 12 V,通常串联多只):若单只使用,R = (12 − 1.8) / 0.02 ≈ 510 Ω。
  • 功率校验:在 If=20 mA、Vf≈1.8 V 时器件耗散约 36 mW,仍在最大耗散 60 mW 范围内;请勿长期超额驱动,以免加速老化或损坏。
  • 极性注意:LED 为极性器件,安装时注意正负极(阳极、阴极)方向。
  • 环境与焊接:插件式封装建议使用合适的焊接温度和时长,避免长时间高温损伤封装和内部芯片。实际生产中遵循厂家推荐的焊接工艺参数。
  • 静电防护:芯片对静电敏感,装配与测试过程中建议采取防静电措施。

六、可靠性与包装

MHL3014URTD 采用成熟封装和工艺制造,寿命长、亮度衰减慢。常见出厂包装为托盘或卷盘/带装(视采购批次和供应方式),便于批量装配。对于有特殊可靠性要求的项目,可与供应商确认加速老化、寿命和环境测试数据。

七、选型与注意事项

  • 若需要更宽光角或更高亮度,可考虑同系列其它规格或更大封装型号;
  • 若用于高温或户外环境,应关注配套散热和密封防护设计;
  • 选型时确认实际工作电流与亮度需求,避免长期在额定极限值工作以延长寿命。

总结:MHL3014URTD 是一款适用于通用指示与信号显示的 3mm 红色插件 LED,具备窄角度高方向性、高显色和稳定的电气性能,便于装配与工程应用。若需完整数据手册、光电曲线或样品测试建议联系 MEIHUA 官方或授权分销渠道获取详细资料。

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.

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
