MHT153UGCT 产品概述
一、产品简介
MHT153UGCT 是美华（MEIHUA）推出的一款高亮翠绿色贴片发光二极管（LED），采用通透无色透镜与1206表面贴装封装，中心峰值波长518nm（范围510–530nm），发光角度窄（15°），具备高方向性和强烈的点光源效果，适合精密指示、信号显示及光学耦合等场合。
二、主要电光参数
- 发光颜色：翠绿色
- 峰值波长：518 nm（范围 510–530 nm）
- 正向电压（Vf）：2.7 V ～ 3.4 V
- 正向电流（If）：20 mA（典型工作电流）
- 功率：95 mW（器件额定功率）
- 发光强度：11,200 mcd（在标准测试条件下）
- 发光角度：15°
- 透镜：无色透明
- 工作温度：-40 ℃ ～ +85 ℃
三、应用场景
- 仪表、工业控制与状态指示灯
- 精细光学指向与点光源显示（狭角照明、瞄准标志）
- 光电传感器耦合、光纤耦合端口
- 消费电子、医疗设备与交通信号指示
四、使用建议与电路设计
- 限流电阻计算：R = (Vcc − Vf) / If。为保证不超流，常采用Vf的最小值2.7 V作为计算基准（即最不利情况）。
- 以5 V 供电为例：R = (5 − 2.7) / 0.02 = 115 Ω，建议选用120 Ω或更大（并考虑容差、温漂）。
- 以3.3 V 供电为例：若Vf接近或超过3.3 V，LED可能不亮或亮度极低；以Vf最小值2.7 V计算，R ≈ 30 Ω（可选33 Ω），但需注意Vf变动带来的亮度差异。
- 功率与热管理：在If=20 mA 时器件自身功耗约 Vf×If（典型值约60–68 mW），低于额定95 mW，但长时间高温工作仍需降额设计并保证PCB散热路径可靠。
- ESD 与焊接：为表面贴装器件，适合回流焊工艺。焊接时遵循通用的回流温度曲线并避免超温停留，生产环境需做好静电防护措施（ESD）。
五、封装与可靠性
- 封装：1206（SMD），适用于自动贴装与波峰/回流焊工艺。建议参考厂方推荐的焊盘尺寸与回流曲线以确保焊点可靠性。
- 环境适应性：工作温度范围广（-40 ℃ 至 +85 ℃），可满足常见工业级温度需求。为延长寿命，建议在高温或高电流条件下进行降额使用。
六、选型与注意事项
- 若应用要求极窄光束或对比度高的指示，MHT153UGCT 的15°发光角和高光强非常适合；若需更宽视角或柔和光线，应考虑其他透镜设计。
- 设计限流时优先按最小Vf计算以防过流，并为批次间Vf漂移留出裕量；需在样品阶段通过实测确认亮度与颜色一致性。
- 存储与加工时请按通用LED湿敏等级和ESD规范处理，避免长时间潮湿暴露或静电损伤。

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.
