MHK2396EGBTD 产品概述
一、产品简介
MHK2396EGBTD 为美华（MEIHUA）出品的双色发光二极管模块，封装为 DIP-4（2.54mm 间距），外形约 11.8 × 4.3 mm。器件内置红、绿两颗 LED，雾状彩色透镜可实现均匀散射光效，适合面板指示与状态显示应用。
二、主要电光参数
- 正向电流（IF）：典型 20 mA（最大额定值请参见规格书）
- 最大功率耗散：78 mW（器件热限制）
- 波长/颜色：绿色 568 nm（雾状绿色透镜）；红色 628 nm（雾状红色透镜）
- 正向压降（Vf）：红色 ≈ 1.85 V；绿色 ≈ 2.00 V（典型值）
- 发光强度（IF=20 mA）：绿色 ≈ 55 mcd；红色 ≈ 25 mcd
- 发光角度：75°（半值角）
- 工作温度范围：-25 ℃ ~ +85 ℃
以上为典型/代表性参数，实际使用中请参考完整数据手册与测试条件。
三、封装与安装建议
DIP-4 封装，针脚间距 2.54 mm，便于通孔安装与快速插装。建议 PCB 钻孔孔径 0.8–1.0 mm，留孔周边焊盘配合通孔焊接。透镜投射出光锥约 75°，布板时注意光学遮挡与可视范围。
四、典型驱动与热管理
- 建议使用限流电阻或恒流驱动器控制电流，避免超流。
- 典型限流电阻计算（取 IF=20 mA）：
- 5 V 供电：绿色 R ≈ (5.0−2.0)/0.02 = 150 Ω；红色 R ≈ (5.0−1.85)/0.02 ≈ 158 Ω（可取 150–180 Ω 标准值）
- 3.3 V 供电：绿色 R ≈ 65 Ω；红色 R ≈ 73 Ω。
为延长寿命与降低发热，常规指示可将工作电流下调至 10–15 mA。
五、典型应用
面板指示、状态灯、仪器仪表、家用电器指示、通信设备指示灯、嵌入式开发板等需要双色指示的场景。雾状透镜适合近距离观看并能减少光斑眩光。
六、使用注意事项
- 焊接时控制温度与时间，避免长期高温烘烤导致透镜变色或内部损伤；推荐手工焊接或回流曲线参照厂家说明。
- 工作环境潮湿或有腐蚀性气体时需防护处理。
- 若需更高亮度或更严格一致性，建议按批次测试并配对筛选。
如需完整电气/光学特性曲线、引脚图与回流焊曲线，请提供具体需求以便提供详细资料或原厂数据手册。

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.
