MHS190CRCT 0603 红色发光二极管 产品概述
一、核心参数
MHS190CRCT 是美华（MEIHUA）出品的红色 SMD 发光二极管，封装为 0603（0.6 × 1.6 mm），载带方式为侧贴。主要电光参数：正向电压 Vf ≈ 2.2 V，额定正向电流 If 5 mA，最大功率耗散约 60 mW；峰值波长 632 nm（光谱范围 617.5–633.5 nm）。透镜为无色透明，典型发光强度 45 mcd，半角发光角度约 120°。工作温度范围 -40 ℃ 至 +85 ℃。
二、光电性能说明
该器件发出典型的纯红光，峰值 632 nm，适合指示与面板显示类应用。45 mcd 的亮度在 5 mA 驱动下属于中等指示亮度，配合 120° 宽视角，能够在较大面角范围内保持明显可见性。由于额定功耗 60 mW，设计时需保证 If 与功耗不超过额定值以避免热衰减和寿命降低。
三、封装与机械特性
0603 尺寸使其非常适合空间受限的移动设备、可穿戴终端及微型控制面板。透明透镜利于颜色纯度和光线散射控制。侧贴载带便于高速贴装器件方向控制和自动化生产。建议在 PCB 布局时考虑散热路径与焊盘尺寸匹配，保证焊点可靠性和热管理。
四、典型应用场景
- 工业与消费电子的状态指示灯（电源、工作指示、报警等）
- 仪表与控制面板的小型信号显示
- 可穿戴设备与智能终端的指示标识
- 需要宽视角且功耗受限的背光或指示场合
五、安装焊接与使用建议
- 驱动与限流：推荐恒流驱动或在串联中加入限流电阻。举例：直流 5 V 时，R = (5 - 2.2) / 5 mA ≈ 560 Ω；3.3 V 时，R ≈ 220 Ω（仅作示例，实际电路请根据允许误差与功耗校核）。
- 焊接工艺：采用无铅回流焊装配，按器件制造商回流曲线执行，避免超时高温造成光衰或封装损伤。
- 防静电：为半导体器件，应采取 ESD 防护措施（佩戴手环、使用接地台面等）。
六、可靠性与储存注意
- 工作时应避免长期过流或过热，功耗与结温超限会加速光衰和失效。
- 储存时保持干燥，未封装的元件应按湿敏等级处理并在推荐时间内回流。
- 使用环境需考虑温度范围（-40 ℃ 至 +85 ℃）与可能的化学腐蚀性气氛，避免长期暴露在高湿或腐蚀性气体中。
总结：MHS190CRCT 0603 红色 LED 以其小巧体积、稳定的红色光谱与宽视角特性，适合空间受限且需中等亮度指示的电子产品。设计时注意限流、热管理与回流焊工艺，可获得长期稳定的指示效果。

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.
