MHL5019EGTD 发光二极管（5mm 圆形）产品概述
一、产品简介
MHL5019EGTD 是 MEIHUA（美华）出品的插件式 5mm 圆形发光二极管，封装形式为 D=5mm 的通孔（LED_D5X10.4MM_TM）。该器件为共阴极（Common Cathode）二极管，提供红色与黄绿色两种发光颜色，具有稳定的电光特性与广角可视特性，适用于面板指示、仪表状态、信号提示及一般照明指示类应用。
二、主要电气与光学参数
- 额定正向电流（If）：20 mA（最大典型驱动电流，建议使用限流器或恒流源驱动）
- 最大功耗：85 mW
- 正向压降（Vf，典型）：红色 ~2.1 V；黄绿色 ~2.2 V
- 工作波长 / 峰值波长：黄绿色 570 nm（峰值 572 nm）；红色 622 nm（峰值 632 nm）
- 发光强度（Iv，典型）：黄绿色约 30 mcd；红色约 20 mcd
- 发光角度：120°（宽视角，便于侧向和正向可视）
- 工作温度范围：-25 ℃ ～ +85 ℃
三、封装与机械特性
- 封装形式：插件式（通孔）5mm 圆头，型号名中“D5X10.4MM”表明典型外形尺寸，便于于面板/电路板插装与固定。
- 二极管配置：共阴极（适合多色组合或多管并排布置时统一接地，便于驱动和布线）。
四、使用建议与注意事项
- 驱动方式：建议使用限流电阻或恒流源，典型驱动电流为 20 mA。为延长寿命与降低热应力，可在指示场合采用 5–10 mA 驱动以获得足够亮度并降低功耗。
- 散热与功率管理：单只器件最大功耗 85 mW，实际功耗约为 Vf × If，长时间连续使用时应注意印制板散热与间距。
- 焊接工艺：通孔插件器件应遵守常规波峰/手工焊接温度及时间限制，避免长时间高温以免损伤封装或改变光学特性。
- 极性识别：共阴极器件的公共端为阴极，接地或低电平驱动；各阳极独立，便于多色控制。接线前请确认管脚排列与数据手册一致。
五、典型应用
- 仪表与控制面板指示（状态、警示）
- 消费类电子指示灯（电源、充电、工作状态）
- 工业信号灯、按键背光、楼宇设备指示
- 教学、DIY 与原型开发项目
六、选型要点与可靠性
- 根据可视距离与环境光选择黄绿色或红色：黄绿色在强光下可见性通常更好。
- 若需更高亮度或更小视角，请参考同系列大功率或窄角产品。
- 工作环境温度、频繁开关或高湿环境下应考虑封装防护或选用具备更高可靠性等级的器件。
MHL5019EGTD 以其标准化的 5mm 通孔封装、共阴极方便布线的特性以及稳定的光电性能，适合大多数通用指示与面板显示场景。选择与驱动设计时，建议参照典型正向电压与最大功耗限制，采用合适的限流与散热措施以确保长期可靠运行。

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.
