MHS171CRCT (0805) 红色发光二极管 — 产品概述
一、产品简介
MHS171CRCT 是 MEIHUA（美华）推出的 0805 封装红色发光二极管，侧贴（载带）包装，透明无色透镜，典型用于面板指示、状态灯和便携式电子设备的指示显示。器件在常规驱动条件下呈红色，外观小巧、发散角大，便于高密度贴装与广视角观察。
二、主要电光参数
- 正向电流（IF）：20 mA（额定）
- 最大耗散功率：60 mW
- 正向压降（Vf）：约 2.3 V（典型）
- 峰值波长：632 nm；支配波长/色坐标范围：617.5 nm ~ 629.5 nm
- 发光强度：约 112 mcd（典型，IF=20 mA 条件下）
- 发光角度：140°（宽视角）
- 工作温度范围：-40 ℃ ~ +85 ℃
说明：器件的电学功耗可由 Pd = Vf × IF 估算，按典型值 Pd = 2.3 V × 20 mA ≈ 46 mW，低于最大耗散功率 60 mW，仍需注意在高温或并联阵列时的热管理与降额。
三、封装与安装
0805（约 2.0 × 1.25 mm）小型表贴封装，侧贴载带便于 SMT 贴片机拾取。透明透镜与大视角设计利于指示灯均匀发光。推荐在 PCB 布局时为灯体留足焊盘长度以形成良好焊膏涂覆与焊点可靠性，避免靠近大面积铜箔以减小热梯度对发光效率的影响。
四、设计与驱动建议
- 驱动方式：恒流驱动优先；若采用限流电阻，计算公式 R = (VCC - Vf) / IF。示例：VCC=5 V 时，R ≈ (5 - 2.3) / 0.02 ≈ 135 Ω，可选 150 Ω 标准值。
- 禁止长期过流或超功率工作，以免加速光衰或损坏器件。高环境温度下应适当降额使用。
- 推荐采取抗静电保护措施，并按供应商建议的储存与回流焊工艺处理（遵循常规 SMT 回流规范）。
五、可靠性与注意事项
- 工作温度范围宽，适合工业级环境；但长期高温、高湿或频繁热循环会影响寿命与光输出。
- 裸片/未密封元件应避免潮湿吸收，若长时间暴露于潮湿环境，应按供应商说明进行干燥处理后贴装。
- 安装与测试时注意 ESD 防护，避免正向电流瞬态冲击。
六、典型应用
- 面板与机箱指示灯、状态指示（电源/通讯/故障指示）
- 家用电器与消费电子指示
- 小型信号灯、仪器仪表与指示模块
总结：MHS171CRCT 0805 红色 LED 以小型封装、宽视角与稳定的电光特性，适用于空间受限且需均匀指示光的场合。具体技术参数与可靠性试验数据建议参考美华提供的完整数据手册，并按实际应用环境做降额与热管理设计。

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.
