MHS110RGBCT 产品概述 — MEIHUA(美华)RGB LED,3×1.5mm SMD 共阳极

一、产品简介

MHS110RGBCT 是美华(MEIHUA)推出的一款小型高性价比 RGB 发光二极管,封装为 SMD 尺寸 1.5 × 3 mm,采用共阳极(Common-anode)结构与白色雾状透镜,侧贴(侧视/侧装)安装方式。透镜为磨砂扩散型,发光角度约 120°,适合需要宽广视角与均匀色彩混合的指示与装饰应用。

二、光电与电气参数要点

  • 波长(峰值):R 632 nm,G 518 nm,B 468 nm;实际波长范围:G 520–535 nm、B 465–475 nm、R 622 nm。
  • 正向电流(If):R/G/B 均可达 25 mA(最大额定)。建议常用驱动电流 10–20 mA 以平衡亮度与寿命。
  • 发光强度(Iv):G 180–450 mcd;R 72–180 mcd;B 28–71 mcd(各色典型/范围值,按测试条件而异)。
  • 正向压降(Vf):R 1.6–2.3 V;G 2.4–3.0 V;B 2.5–3.1 V。
  • 功率额定:R 120 mW;G 60 mW;B 60 mW(器件最大耗散能力,设计时留有裕量)。
  • 发光角度:120°(较宽视角,有利于均匀照明和视觉半径覆盖)。
  • 工作温度:-40 ℃ 至 +85 ℃。

三、抗静电与可靠性注意

抗静电能力(ESD)存在颜色间差异:R 色可达 2000 V,G 与 B 约 150 V。生产与装配时必须加强对 G、B 色的防静电保护:佩戴接地手环、使用防静电工作台、保持包装及搬运环境接地。长期工作建议留有电流裕量并避免持续高温环境。

四、驱动与电路建议(共阳极)

该器件为共阳极,内部阳极需接至正供电(例如 Vcc),各色通过下拉(sink)至地控制。驱动建议:

  • 使用限流电阻或恒流驱动器以控制 If;若采用电阻,计算公式 R = (Vcc - Vf) / If。
  • 以 5 V 供电、设计 If = 20 mA、取 Vf 中值(示例计算):
    • R:R ≈ (5 - 1.95)V / 0.02A ≈ 150 Ω;
    • G:R ≈ (5 - 2.70)V / 0.02A ≈ 120 Ω;
    • B:R ≈ (5 - 2.80)V / 0.02A ≈ 110 Ω。
  • 在 3.3 V 供电下,若 Vf 接近上限(G、B 可达 3.0–3.1 V),驱动电流会显著减小,可能无法达到额定亮度,需注意电源与 Vf 的匹配。
  • 推荐优先使用恒流驱动器或 PWM 控制以实现精确亮度与色彩混合。

五、机械与装配建议

  • 封装尺寸 1.5 × 3 mm,侧贴安装,布板时注意器件方向与发光方向保持一致,避免被遮挡。
  • 采用白色雾状透镜有利于色彩混合与柔和出光,适合直接视感要求高的面板或指示场合。
  • 推荐在 PCB 布局中为每颗 LED 留出散热通道和合理焊盘,避免贴片后热聚集影响寿命与亮度一致性。

六、典型应用场景

  • 消费电子指示灯、状态指示与菜单提示;
  • 小型背光、按键指示与面板装饰灯;
  • 穿戴设备、玩具与模型灯光效果;
  • 单板电脑或小型控制器的多色指示与色彩提示。

总结:MHS110RGBCT 以其小尺寸、宽视角及雾面透镜提供了良好的色彩混合与扩散效果,适合对外观与指示效果有要求的电子产品。在设计时应重视共阳极驱动方式、Vf 与供电电压的匹配以及对 G/B 色的防静电保护,以确保稳定性与长寿命。若需具体引脚脚位图、回流焊曲线或更多电光特性曲线,请参考厂方规格书或联系我们获取更详细资料。

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
