MHK2512RGTD — 双色指示型发光二极管（DIP-4，2.54mm）
一、产品概述
MHK2512RGTD 为 MEIHUA（美华）出品的双色双灯座发光二极管，采用标准 DIP-4（针距 2.54mm）直插封装，内含红色与黄绿色两颗 LED。外壳为雾状彩色透镜（雾状红色、雾状绿色），适合面板指示、状态显示及通用电子装配使用。工作温度范围 -25℃ 至 +85℃，结构紧凑，便于插装与板间连接。
二、主要电光参数
- 推荐正向电流（If）：5 mA（单色）
- 额定功率：78 mW
- 发光颜色与波长：
- 黄绿色：典型波长 568 nm（峰值 574 nm）
- 红色：典型波长 628 nm（峰值 636 nm）
- 正向压降（Vf）：黄绿色 ≈ 2.2 V；红色 ≈ 2.0 V
- 光强（Iv）：黄绿色 ≈ 30 mcd；红色 ≈ 20 mcd（在 If = 5 mA 条件下）
- 发光角度：黄绿色 ≈ 120°；红色 ≈ 80°
（以上为典型值，设计时请参照厂方详细数据表进行裕量设计）
三、典型应用场景
- 仪器仪表、控制面板的状态指示灯
- 消费类电子产品的功能/状态提示
- 信号指示模块与教学实验板（兼容 2.54mm 面包板）
- 交通/安防小型指示系统与标识灯
四、使用与设计建议
- 限流电阻计算（以常见电源为例）：R = (Vcc - Vf) / If
- 若 Vcc = 5 V：红色 R ≈ (5 − 2.0) / 0.005 = 600 Ω（常用取 620 Ω）；黄绿色 R ≈ (5 − 2.2) / 0.005 = 560 Ω（常用取 560 Ω）
- 若 Vcc = 12 V：红色 R ≈ 2 kΩ；黄绿色 R ≈ 1.96 kΩ（取 2 kΩ）
- 推荐按 If = 5 mA 设计以获得平衡的亮度与寿命；若需更高亮度，应参考最大额定电流与热设计要求。
- 作为直插器件，装配时注意焊接工艺与热影响，建议遵循厂家推荐的回流/波峰焊工艺参数。
五、存储与可靠性建议
- 贮存时避免潮湿、强光与高温，长期存放建议密封防潮并置于干燥箱中。
- LED 对静电敏感，生产与装配过程请采取 ESD 保护措施。
- 常规使用环境温度在 -25℃ 至 +85℃，超出范围会影响光输出与寿命，应采取相应的热管理与环境保护。
六、小结
MHK2512RGTD 为一款面向通用指示与信号显示的双色直插 LED 模块，封装规范、便于装配，红/黄绿色配色适合对比明显的状态指示。设计时请参考上述典型参数与限流计算，并以厂方数据表为准进行最终电气与热设计。若需批量采购或获取完整数据表与封装尺寸图，请联系 MEIHUA（美华）或其授权经销渠道。

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.
