MHS190CGCT 产品概述

一. 基本特性

MHS190CGCT 是美华(MEIHUA)推出的一款小体积高性价比侧贴式发光二极管(LED),封装规格为 0603(实尺寸 0.6 × 1.6 mm),采用无色透明透镜,发出黄绿色光(黄绿色/绿黄调)。该器件设计用于低功耗、低电流指示和背光场合,适合贴片自动化生产和高密度电路板应用。工作环境温度范围为 -40 ℃ 至 +85 ℃,适应一般消费电子和工业控制的温度要求。

二. 光学与电气参数

  • 发光颜色:黄绿色
  • 发光波长:565.5 nm ~ 573.5 nm(峰值波长 575 nm)
  • 正向正负压降(Vf,典型值):2.2 V(以 If = 5 mA 时为参考)
  • 正向电流(If):5 mA(典型工作点)
  • 功率:60 mW(最大功耗/额定功率)
  • 发光强度:22.5 mcd(典型值,通常是在指定测试条件下测得)
  • 发光角度:120°(半强度角较宽,适合面照式指示)
    以上参数为器件典型值或额定值,具体设计时应参考厂商完整数据手册并考虑工况校正。

三. 封装与机械特征

  • 封装形式:SMD(表面贴装)0603
  • 实际外形尺寸:0.6 mm × 1.6 mm(小尺寸、适合高密度 PCB 布局)
  • 透镜颜色/形状:无色透明透镜,光分布均匀,便于实现较宽的视角
  • 载带方式:侧贴(适配常见贴片机与回流焊工艺)
    该封装便于自动化贴装,适用于有限空间的面板及指示灯列阵。设计 PCB 时建议采用厂方推荐的焊盘和阻焊孔,以保证良好焊接和热可靠性。

四. 典型应用场景

  • 按键/指示灯:电源、状态指示、通信指示等低电流指示用途
  • 可穿戴设备与便携终端:低功耗环境下的提示灯
  • 仪器仪表面板与控制面板:需要小尺寸指示且视角较宽的场合
  • 家电与消费电子:LED 状态指示与信号提示
    MHS190CGCT 以其低功耗、稳定光色及小尺寸优势,适合对空间和功耗有较高要求的产品设计。

五. 选型与电路设计建议

  • 驱动电流:推荐典型工作电流为 5 mA,以保证发光强度和寿命的平衡。若需要更高亮度可适当短时增加电流,但应注意热量和寿命影响。
  • 限流电阻举例:若使用 5 V 电源并以 If = 5 mA 工作,限流电阻可按 R = (Vcc − Vf) / If 计算,即 R ≈ (5.0 − 2.2) / 0.005 ≈ 560 Ω;若使用 3.3 V 电源,R ≈ (3.3 − 2.2) / 0.005 ≈ 220 Ω。实际选型时应考虑零件容差与电源波动。
  • 驱动方式:建议采用恒流源或串联限流电阻的稳态驱动;避免直接脉冲过驱以免热累积或寿命下降。
  • 电磁兼容与滤波:在需要 PWM 调光时建议加前端滤波或软启动以避免电磁干扰。

六. 装配与可靠性注意事项

  • 回流焊:0603 SMD 通常采用回流焊工艺,遵循厂方建议的回流温度曲线(通常对应无铅回流峰值温度约 245–260 ℃,具体以数据手册为准)。
  • 防静电措施:LED 对静电敏感,装配和测试环节应采取 ESD 防护(佩戴接地手环、使用防静电台垫等)。
  • 湿敏与储存:如长期储存建议遵循湿敏等级(若数据手册规定)进行密封防潮包装;如包装打开后高温回流前需做烘烤以去除吸湿。
  • 工作环境:长期在接近或超过额定温度(+85 ℃)的环境中使用会影响光输出与寿命,设计时应预留热量管理空间。

七. 采购与品牌信息

  • 产品型号:MHS190CGCT(黄绿色,0603 封装)
  • 品牌:MEIHUA(美华)
    在选型和批量采购前建议索取厂商完整数据手册与样品进行实板验证,确认光色、亮度与焊接兼容性满足最终产品要求。如需进一步的焊盘建议、回流曲线或可靠性试验数据,可联系供货商获取详细资料。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
