MHK1339EGBDT 产品概述
一、产品简介
MHK1339EGBDT 是美华（MEIHUA）推出的一款双色发光二极管（LED），封装为插件式（P=2.54mm），外形尺寸约 7×6.35mm，采用共阴极（共阴）结构，内含红色与黄绿色两颗发光芯片。该器件适用于仪表指示、面板状态显示、信号指示和一般光源提示场合，具有宽视角与稳定的电光特性，易于电路集成与替换维护。
二、主要电光参数
- 发光颜色：红色、黄绿色
- 峰值波长：红色 624nm，黄绿色 569nm
- 波长范围：红色 622–632nm，黄绿色 564–574nm
- 正向压降（Vf）：红色 ≈2.0V，黄绿色 ≈2.1V（典型值）
- 正向电流：IF = 20mA（典型工作电流）
- 功率（光学/电学标称）：55mW / 70mW（型号对应）
- 发光强度：57mcd（典型）
- 发光角度：140°（宽视角）
- 工作温度：-25℃ ～ +85℃
三、引脚与连接方式
- 二极管配置为共阴极，常见接法为将共阴脚接地（GND），分别通过限流电阻驱动红色与黄绿色的阳极。
- 驱动示例（5V 电源）：
- 红色限流电阻 R ≈ (5V − 2.0V) / 20mA ≈ 150Ω
- 黄绿色限流电阻 R ≈ (5V − 2.1V) / 20mA ≈ 145Ω（可取标准 150Ω）
四、应用建议与可靠性
- 驱动方式：建议恒流驱动或在每色串联合适限流电阻，以避免电流过大造成寿命下降。
- 热管理与寿命：在高温环境下应适当降额使用，长期工作建议低于最大额定电流以延长寿命。
- 反向电压与过流保护：避免施加反向高压与瞬态过流，必要时加保护二极管或限流器。
- 焊接建议：作为插件封装，遵循常规手工或波峰焊工艺，避免长时间高温烘烤导致塑料件变形（建议快速焊接，参考常用插件元件工艺）。
五、典型应用场景
- 工业控制面板、仪表指示灯
- 仪器仪表、通讯设备状态显示
- 家电按键或指示灯、电子玩具和小型标识灯
- 双色提示需求的场合（如两色切换状态显示）
六、选型与注意事项
- 在选型时确认所需峰值波长与发光强度是否满足可视性要求；若需更高亮度或更小角度指向性，可考虑其它封装或高亮型号。
- 由于为共阴结构，驱动电路需为共阴兼容设计；若系统为共阳设计需选用共阳器件或改变接法。
- 如需批量采购或获取完整规格书（含极限参数、封装图与焊接条件），建议联系 MEIHUA 或其代理商索取正式数据手册。
本概述基于 MHK1339EGBDT 的典型参数与常用应用经验，供工程选型与电路设计参考。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
