MHK33153UGBTD 产品概述
一、产品简介
MHK33153UGBTD 是美华（MEIHUA）推出的一款绿色发光二极管（LED），采用插件封装（引脚间距 P=2.54mm），雾状绿色透镜，适用于面板指示、信号提示与一般照明指示场合。典型发光波长 522nm，色彩纯正、肉眼识别度高，雾状透镜配合85°的发光角度，可获得均匀、柔和的扩散光效。
二、主要电学与光学参数
- 发光颜色：绿色（峰值波长 522nm）
- 正向电压（Vf）：3.4V（典型）
- 额定正向电流（If）：20mA
- 额定功率：78mW（器件额定值）；典型耗散约 Vf×If = 3.4V×20mA ≈ 68mW
- 发光强度：1600mcd（典型）
- 发光角度：85°
- 透镜：雾状绿色透镜（利于漫射与去眩光）
- 工作温度范围：-40℃ ～ +85℃
三、驱动与参考电路
LED 为恒流器件，应使用限流方式驱动。常见限流电阻计算公式：R = (Vs - Vf) / If。
- 典型示例：5V 系统，R = (5 - 3.4) / 0.02 = 80Ω → 取标准值 82Ω；电阻功耗约 I^2·R ≈ 0.33W，建议选 0.25–0.5W 额定功率电阻。
- 12V 系统，R = (12 - 3.4) / 0.02 = 430Ω → 可选择 430Ω 或 470Ω（470Ω 时电流约 18.3mA）。
注意：若仅有 3.3V 电源，因 Vf=3.4V，直接驱动无法满足，应改用升压驱动或专用恒流驱动器。
四、应用场景
适用于：面板指示灯、工业设备状态指示、家电与消费电子按键背光、仪器仪表指示、原型开发与教学。插件封装与 2.54mm 引脚间距方便手工焊接和快速更换，适合样机与小批量生产。
五、装配与使用建议
- 推荐恒流驱动或限流电阻驱动，避免长时间过流运行；如需调光，优先采用 PWM 控制，频率与占空比根据视觉效果与驱动器能力调整。
- 环境高温时应适当降额（降低正向电流）以延长寿命。
- 插件封装便于波峰焊或手工焊接，焊接温度与时间请参考一般电子元件工艺（例如≤260℃、短时接触），如有严格工艺要求请咨询供应商数据表。
- 存储与使用避免潮湿、强光直射与剧烈机械应力。
六、可靠性与选用建议
该型号适合一般工业与消费类指示用途，但非汽车级高可靠器件。关键/安全系统应依据可靠性需求进行额外验证与寿命测试。采购时建议索取完整数据手册，确认典型与最大值参数、测试条件与质量认证。
总结：MHK33153UGBTD 以稳定的绿色发光、良好的扩散效果和方便的插件封装，适合多种指示与显示应用。根据系统电源选择合适的限流方式与热管理措施，可获得长期稳定的工作表现。

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.
