MHL3014UYTD — 黄光发光二极管（3mm）产品概述
一、产品概述
MHL3014UYTD 是 MEIHUA（美华）推出的一款高亮黄色发光二极管，采用通孔插件式 3mm 圆形灯头封装，适用于各种指示与小面积照明场合。该器件在典型驱动条件下呈现稳定的黄光输出，峰值波长约 593nm，视觉上为明亮的黄色指示效果。
二、主要参数
- 发光颜色：黄色（黄光）
- 峰值波长：593nm（典型）
- 标称波长：590nm
- 发光强度：280 mcd（@ If = 20 mA，典型）
- 发光角度：40°
- 正向电流（If）：20 mA（最大额定工作电流）
- 正向压降（Vf）：约 2.0 V（@ If = 20 mA，典型）
- 最大功率耗散：80 mW（器件总耗散限值，注意热管理）
- 工作温度：-25 ℃ ~ +85 ℃
- 封装形式：插件，D = 3 mm 圆头
- 品牌：MEIHUA（美华）
- 型号：MHL3014UYTD
三、光学与电气特性
在标准驱动条件（If = 20 mA）下，该型号可提供约 280 mcd 的光强，光束集中（半角约 20°，全角约 40°），适合需要定向指示的应用。典型正向压降约 2.0 V，设计电路时应考虑此 Vf 值并配置限流元件。最大功率耗散 80 mW 表明需注意封装与PCB的散热，避免长期在极限功率下工作。
四、封装与机械特性
器件为直插式 3mm 圆形透镜结构，易于手工或波峰/回流焊接装配（注意工艺温度限制与焊接时间）。极性识别：长脚为阳极（Anode），短脚为阴极（Cathode），灯体侧面或底部常有极性标识，装配时请核对极性以防反接。
五、使用与焊接建议
- 驱动：建议使用限流电阻或恒流源驱动，限流电阻计算示例（5 V 电源）：R = (5 V − 2 V) / 20 mA ≈ 150 Ω。
- 降额运行：为延长寿命和提高可靠性，建议实际工作电流低于 20 mA（如 10–15 mA）。
- 焊接：避免长时间高温暴露，手工焊接建议在 260 ℃ 以下、焊接时间尽量短。
- 散热：长时间或高频闪烁应用应注意PCB铜箔面积和散热路径，确保器件温度在额定范围内。
- 存储：避免潮湿、强光及静电环境，防止器件老化或损伤。
六、典型应用场景
- 面板与设备状态指示灯
- 仪器仪表与控制面板指示
- 家电与消费电子状态提示
- 小型指示照明与信号指示
七、注意事项与可靠性提示
- 避免反向高压和过流，反向电压和瞬间浪涌可能损坏芯片。
- 在高温或高湿环境下，应采取相应防护与降额设计。
- 出于人眼舒适与安全考虑，长期直视高亮 LED 不建议。
总结：MHL3014UYTD 提供稳定、集中且可读性强的黄光指示输出，适合多种通用指示场合。合理的驱动与散热设计能显著提升使用寿命与可靠性。若需更详细的电气特性曲线或封装尺寸图，请提供具体需求以便补充数据表。

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.
