MHK1374CYBTD 产品概述

一、产品简介

MHK1374CYBTD 是美华(MEIHUA)推出的一款黄色发光二极管,采用插件封装(引脚间距 P=2.54mm),透镜为雾状黄色,呈扩散型光束输出。器件在典型驱动电流 20mA 工作点下表现稳定,适合常规指示、面板标识及背光等需要柔和黄色显示的应用场景。

二、电学与光学参数

  • 额定正向电流(IF):20 mA(典型工作点)
  • 正向压降(Vf):约 2.05 V(在标准试验电流下)
  • 峰值波长:约 585 nm(规格也给出 587 nm,属黄色光谱范围内)
  • 发光角度:80°(中等扩散视角,配合雾状透镜获得均匀亮度分布)
  • 标称功率:75 mW(按产品资料提供为器件最大额定功耗或散热参考,实际电气输入功率在 20mA、2.05V 条件下约 41 mW)
  • 工作温度范围:-40 ℃ 至 +85 ℃

注:光学指标通常以特定测试条件(电流、温度、光学测量距离)给出,实际装配和驱动方式会影响主观亮度与色度。

三、封装与机械特性

  • 封装形式:插件(直插)
  • 引脚间距:2.54 mm,兼容通用面包板和插孔式电路板布局
  • 透镜:雾状黄色透镜,降低镜面眩光,提升近距离可视均匀性
  • 建议焊接方式:常见的手工或波峰/回流(插件元件波峰)焊接工艺,注意控制加热曲线避免过热

四、使用建议与电路设计

  • 恒流驱动:推荐使用恒流源或限流电阻配合驱动。示例:5 V 电源下,限流电阻 R ≈ (5.00 − 2.05) / 0.02 ≈ 148 Ω,可选 150 Ω;3.3 V 电源下 R ≈ (3.30 − 2.05) / 0.02 ≈ 62.5 Ω,可选 68 Ω。
  • PWM 调光:支持 PWM 调光以控制亮度,建议 PWM 频率 > 200 Hz 以避免肉眼闪烁;占空比控制时仍需保证峰值电流不超过器件允许值。
  • 热管理:虽然典型工作电流下器件发热有限,但在高密度阵列或长期连续点亮下,应考虑散热与通风,避免超出 +85 ℃ 工作上限。
  • 并联使用:并联多个 LED 时,建议为每个 LED 配置独立限流或采用恒流分支,以避免电流不均导致早期失效。

五、可靠性与环境适应

  • 工作温度范围宽(-40 ℃ ~ +85 ℃),适合工业级和室外部分受控环境应用。
  • 对静电敏感,建议在生产与安装过程中采取 ESD 防护措施(佩戴接地腕带、使用防静电工作台等)。
  • 长期可靠性受驱动电流与结温影响,建议在规格范围内留余量以延长寿命。

六、典型应用场景

  • 面板与设备指示灯(状态、电源、告警等)
  • 仪器仪表与电子玩具指示
  • 背光与提示照明(需柔和黄色)
  • 教育、原型开发与面包板试验

七、包装、存储与注意事项

  • 存储时避免强光直射、高温高湿环境,推荐干燥、防潮保存。
  • 插件元件在波峰焊接或回流过程中,注意控制温度与时间,避免超过制造商推荐的焊接极限(通常峰值温度及持续时间应参照具体生产资料)。
  • 安装时注意极性方向,避免反向电压击穿;若存在反向工作需求,应加保护电路。

如需更详细的电光参数曲线(光强-电流、波长随温度漂移、典型 IV 曲线)、封装图或可靠性测试数据,建议索取厂家完整数据手册以便进行精准设计与验证。

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
