MHL3014UBTD — 3mm 蓝光发光二极管产品概述

一、产品概述

MHL3014UBTD 是美华(MEIHUA)推出的一款高亮度蓝色发光二极管(LED),采用经典 3mm 圆头插件封装,适用于各种指示与背光场合。该器件以稳定的光学特性和良好的可靠性为特点,便于在通用电子产品和工业设备中实现清晰、集中的蓝色指示效果。

二、主要技术参数

  • 型号:MHL3014UBTD
  • 品牌:MEIHUA(美华)
  • 封装:插件,D = 3mm(圆形透镜)
  • 发光颜色:蓝色
  • 峰值波长(λp):468 nm(典型)
  • 波长:470 nm(名义)
  • 典型发光强度:1520 mcd(测量条件通常为 If = 20 mA)
  • 发光角度:60°(典型)
  • 正向电压(Vf):3.2 V(典型,If = 20 mA)
  • 正向电流(If):20 mA(典型工作电流)
  • 最大功耗:120 mW(器件功率额定值)
  • 工作温度范围:-25 ℃ ~ +85 ℃

说明:上述数值为典型或额定参考值,实际使用时应参照正式数据手册和应用条件进行校核。

三、光学特性

MHL3014UBTD 在典型驱动电流下呈现纯净的蓝色光,峰值波长约 468 nm,主观视觉明亮且色彩饱和。60° 的半功率发光角度有利于形成集中但覆盖合理的照射区域,适合指示灯与面板照明等需要方向性光束的应用。

四、电气特性与驱动建议

  • 建议工作电流:典型 20 mA;为延长寿命与降低热应力,可考虑 10–15 mA 的降低电流方案。
  • 驱动方式:优先采用恒流驱动器以保证亮度一致性与长期稳定性;在简单电路中可使用限流电阻。
  • 限流电阻示例(假设电源 5 V,If = 20 mA,Vf = 3.2 V):R = (5.0 − 3.2) / 0.02 ≈ 90 Ω,取接近标准阻值 91 Ω。
  • 注意避免长时间承受过高电流或过高功耗以免加速光衰或损坏。

五、封装与机械特性

MHL3014UBTD 为常规 3mm 插件型 LED,圆形透镜便于面向观测方向的安装与固定。引脚适配常见 PCB 孔径与手工/波峰焊接工艺,便于批量装配和维修更换。具体外形尺寸请参考产品数据手册或供应商样品图。

六、环境与可靠性

工作温度范围 -25 ℃ 至 +85 ℃,适用于大多数商业与工业环境。器件在正常使用条件下具有较长寿命与稳定性,但在高温、高湿或强腐蚀性环境中需结合封装保护或额外密封措施。建议在防静电环境中操作与储存以降低静电损伤风险。

七、典型应用

  • 仪器仪表与指示灯
  • 家用电器面板指示
  • 消费电子状态指示(如遥控器、充电指示等)
  • 玩具与教育设备照明
  • 小型标识与指示牌

八、采购信息与使用注意

  • 订购型号:MHL3014UBTD(MEIHUA)
  • 询价时请注明封装形式(插件)、颜色(蓝)与数量。
  • 使用时遵循厂商推荐的使用条件,避免长期在最大功率下驱动;安装焊接时遵循通用插件元件的温度和时长规范以防损伤。

九、总结

MHL3014UBTD 是一款面向通用指示与照明应用的 3mm 高亮蓝色 LED,具有良好的发光强度和适中的光束角度,支持标准 20 mA 的驱动电流并具备广泛的环境适应能力。其插件封装便于系统集成与维护,是指示、背光等场合的经济可靠选择。如需更详细的电光参数、失效机制或封装图纸,请联系供应商索取完整数据手册。

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
