MHK1375UGBTD 翠绿色发光二极管产品概述

一、概述

MHK1375UGBTD 是美华(MEIHUA)推出的一款高亮翠绿色插件发光二极管,封装尺寸约为 4.6×8.4 mm,针脚间距 2.54 mm,型号标注为 LED_4.6X8.4MM_TM。该器件采用雾状绿色透镜,用于提供均匀柔和的出光效果,适合指示、面板显示及背光等应用场景。

二、光电性能要点

  • 发光颜色:翠绿色
  • 峰值波长:520 nm
  • 正向电压(Vf):约 3.0 V(典型)
  • 额定正向电流(If):20 mA
  • 发光强度:1500 mcd(典型)
  • 发光角度:100°(宽视角,视觉覆盖面积大)
  • 额定功率:80 mW(器件最大耗散)

在额定条件(If=20 mA)下,LED 功耗约为 P = Vf × If ≈ 3 V × 20 mA = 60 mW,低于器件额定功率裕量,便于长期稳定工作。

三、环境与可靠性

  • 工作温度范围:-40 ℃ 至 +85 ℃,适应宽温度环境
  • 封装形式为插件(Through-hole),便于手工或波峰/回流焊接后的机械强度与可靠连接
  • 雾状透镜利于扩散光输出,降低眩光并提升面光均匀性

四、驱动与电路建议

为保障稳定与长寿命,建议恒流驱动或在限流电阻配合下使用。典型限流电阻举例(以 5 V 电源为例):

  • R = (Vcc - Vf) / If = (5.0 V - 3.0 V) / 0.02 A = 100 Ω
  • 电阻耗散功率约为 P_R = (Vcc - Vf) × If = 2.0 V × 0.02 A = 0.04 W,使用 1/4 W(0.25 W)电阻足够,但为可靠起见建议选用 0.5 W 或加大散热裕度

注意避免长时间在额定电流上连续工作,建议在高温或密集排列时适当降额(例如 70–80% If)以延长寿命和减少颜色漂移。

五、焊接与装配注意事项

  • 插件式引脚适合通孔焊接,焊接温度和时间应控制在行业常规范围内(如手工焊接 260 ℃ 左右,焊接时间尽量短于 3–5 秒)以避免热应力损伤。
  • 建议在装配和测试过程中避免直接触碰透镜表面,防止污染影响出光均匀性。
  • 存储与运输应防潮、防压,避免强烈震动或机械挤压。

六、典型应用

  • 面板指示灯、状态指示器
  • 仪表与控制设备显示
  • 家用电器与消费电子背光/指示
  • 工业设备信号指示

总结:MHK1375UGBTD 以其稳定的翠绿色发光、宽阔的发光角度与可靠的插件封装,适合各类需均匀指示与良好视角的场合。根据工作环境与使用频率选择合适的驱动与降额策略,可获得长期稳定的光学表现与可靠性。

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
