MHK1375CGBTD 发光二极管（绿色）产品概述
一、产品简介
MHK1375CGBTD 是 MEIHUA（美华）推出的一款直插式绿色发光二极管（LED），外观封装尺寸约 4.6 × 6.5 mm，透镜为雾状绿色，适用于面板指示、背光及一般照明提示。器件为插件型，针距 P = 2.54 mm，便于标准插装与手工焊接。
二、主要参数
- 光色：绿色，峰值波长 568 nm
- 正向电流 If（额定）：20 mA
- 正向压降 Vf：2.2 V（典型）
- 最大功率耗散：78 mW（器件最高允许耗散）
- 发光强度：20 mcd（在额定测试条件下）
- 发光角度：80°（典型）
- 工作温度范围：-25 ℃ ~ +85 ℃
- 透镜：雾状绿色透镜，视觉柔和、扩散良好
三、典型电气连接与计算
推荐工作电流为 20 mA。使用恒压源时需串联限流电阻，计算公式：R = (Vsupply − Vf) / If。举例：5 V 电源下 R ≈ (5.0 − 2.2) / 0.02 ≈ 140 Ω，常用取值 150 Ω，电阻额定功率建议 ≥ 0.125 W。器件最大耗散 78 mW，实际静态功耗 If × Vf（20 mA×2.2 V ≈ 44 mW）低于最大值，但在多灯并联或高环境温时需留余量。
四、封装与安装建议
器件为直插式插件封装，针脚兼容常见面板孔与 PCB 针孔布局。手工焊接或波峰焊均可，但建议焊接温度与时间控制在合理范围，避免超过透镜与内部键合线耐热限度。安装时保持透镜表面清洁，避免强力挤压透镜导致光学性能变化。
五、典型应用场景
适合状态指示、功能提示、仪表面板、家电指示灯、消费电子指示以及需要柔和绿色显示的场合。雾状透镜有利于光的扩散与视觉舒适度，适合近距离视角分布要求较宽的场合。
六、使用与存储注意事项
- 避免静电放电（ESD）直接接触 LED 芯片端子，装配时建议佩戴防静电手环。
- 存储环境应干燥、避免高温高湿，长期暴露在强光或酸碱环境会影响光学性能。
- 超出额定电流和功率会显著缩短寿命或导致失效，设计时应考虑老化及温升影响。
七、选型建议与替代
在对亮度、角度或波长有更严格要求时，可选择更高光强或更窄视角的型号；若需要更高功率或更长寿命，可考虑表贴高亮 LED。选型时关注 If、Vf、光强（mcd）与发光角度的匹配，结合应用环境温度与散热条件做最终确认。
如需更详细的电气特性曲线、光强与角度分布测试数据或封装图纸，可联系供应商获取规范书与样品测试支持。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
