MHT151CYCT 1206 黄色发光二极管（MEIHUA 美华）
一、产品概述
MHT151CYCT 是美华（MEIHUA）出品的1206贴片黄色发光二极管，透明透镜设计提供均匀的发光分布与良好的显色性能。器件峰值波长591nm（波长范围585.5–594.5nm），正向电压约2.35V，额定工作电流20mA，功率约60mW，适用于各类指示与背光场合。
二、主要电气与光学参数
- 发光颜色：黄色；峰值波长：591nm（585.5–594.5nm）
- 正向压降（Vf）：2.35V（典型，20mA）
- 额定正向电流：20mA；功率耗散：60mW
- 发光强度：180mcd（典型，20mA）
- 发光角度：130°；透镜：无色透明
- 工作温度：-40℃ ~ +85℃
三、封装与贴装建议
器件为1206表面封装（典型外形约3.2×1.6mm），载带方式为“反贴”，即元件面朝带底收卷，贴片机取放时需注意吸嘴角度与极性识别。推荐按照常规SMD pad设计保留适当焊盘间距，避免过大焊膏量导致漂移。回流焊应遵循无铅回流曲线，峰值温度与时间按工厂工艺规范控制。
四、热管理与可靠性
在20mA工作点下，Vf×If 约为47mW，低于额定功率60mW，但仍需注意PCB散热与周围器件热积累。长时间高温环境或超额流驱动会加速光衰和寿命下降。储存与焊接期间避免高温高湿和强光直射，实施静电防护（ESD）措施。
五、典型应用场景
适合面板指示灯、按钮背光、小型显示单元、家电指示、工业设备状态提示以及消费电子的小面积照明与信号提示等场合，凭借130°大视角可实现宽视场的均匀显示。
六、注意事项与测试建议
- 选用限流电阻：R = (Vcc − Vf)/If，举例5V供电时R ≈ (5 − 2.35)/0.02 ≈ 132Ω（可选130Ω/150Ω标准值），电阻功率按I^2R计算；
- 在实际应用中建议进行光通量、颜色坐标及老化测试以确认一致性；
- 贴片取放需与反贴载带方向匹配，防止极性错误；
- 对于高速脉冲驱动或高亮度需求，应核对热阻与最大重复脉冲规格并咨询厂家数据表。
如需完整数据手册（包括典型光学曲线、回流焊曲线、尺寸图与电气特性曲线），建议向供应商索取最新规格书以便设计验证与量产控制。

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.
