MHS171CYCT 0805 黄色侧发光 LED 产品概述

一、主要参数

  • 型号:MHS171CYCT
  • 品牌:MEIHUA(美华)
  • 封装:0805(表面贴装)
  • 发光颜色:黄色(透明透镜、侧发光)
  • 波长范围:582.5 nm ~ 591.5 nm
  • 峰值波长:590 nm
  • 正向电流(If):20 mA(最大/标准驱动)
  • 正向压降(Vf):2.35 V(在 If = 20 mA 时典型值)
  • 发光强度:180 mcd(典型值)
  • 发光角度(视角):140°
  • 功率(Pd):70 mW(最大功耗)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 载带方式:侧贴(Tape & Reel 侧向装带)
  • 透镜颜色:无色透明

二、产品特点

  • 小体积封装:0805 尺寸适合高密度 SMT 布局,占板面积小,便于批量贴装。
  • 侧发光结构:光线主要从侧面发出,适合边缘指示、面板侧照或薄型显示背景光设计。
  • 宽视角(140°):提供较宽的可视范围,适用于指示与视觉可见性要求不高但均匀度要求较高的场合。
  • 黄色光谱(~590 nm):典型偏暖黄色,视觉亮度高,常用作状态指示或提示光。
  • 工业级温度范围:-40 ℃ 至 +85 ℃,适合多数工业与商用环境。

三、典型应用场景

  • 面板指示灯、状态指示(设备运行/报警/准备)
  • 仪器仪表及家电指示(按钮指示、背光)
  • 便携设备与移动终端的信号灯
  • 汽车非安全部位指示(需确认汽车规范要求)
  • 标识、指示牌与装饰照明(均匀侧光效果)

四、电气与光学设计说明

  • 正向电压与电流:在 If = 20 mA 时 Vf 约为 2.35 V。器件最大允许电流为 20 mA,超过此值可能缩短寿命或损坏。
  • 功率计算:器件在 20 mA 时的耗散约为 P = Vf × If = 2.35 V × 0.02 A ≈ 47 mW,低于规格的最大耗散 70 mW;但在高环境温度或多个并联密集布局时需注意热堆积。
  • 电流限制建议:使用限流电阻或恒流驱动器。限流电阻计算:
    • 5 V 电源:R = (5 V − 2.35 V) / 0.02 A ≈ 132.5 Ω → 可选 120 Ω~150 Ω(考虑容差)
    • 3.3 V 电源:R = (3.3 V − 2.35 V) / 0.02 A ≈ 47.5 Ω → 可选 47 Ω~51 Ω
  • PWM 调光:建议使用恒流源或在 PWM 控制下确保平均电流与峰值电流均不超过额定值;高频 PWM 有助于避免可见闪烁。
  • 光学一致性:若在阵列中使用,建议按色彩/亮度分bin挑选,保证显示均匀性。

五、封装与装配注意事项

  • 尺寸与焊盘设计:0805 为常见 SMD 尺寸,建议参考制造商或 IPC 标准的焊盘尺寸与焊膏覆盖率,控制焊料量以避免器件倾斜或光学受影响。
  • 回流焊工艺:按通用无铅回流曲线(JEDEC/IPC 建议)进行,避免峰值温度过高或保温时间过长;若无厂方精确曲线,推荐遵循 PCB 组装供应商的通用回流规范(峰值 ≤ 260 ℃,时间短促)。
  • 载带与贴装:侧贴(Side-feed)载带,适配常见贴片机;贴装方向与透镜朝向需依据光路设计调整。
  • ESD 与机械保护:LED 为静电敏感器件,生产/装配/检验过程中需采取防静电措施;避免在装配时对透镜施加过大压力以免影响光学性能。

六、可靠性与储存

  • 环境与老化:工作温度范围 -40 ℃ 至 +85 ℃,长期在高温高湿环境会影响寿命与亮度,建议按环境要求进行降额使用。
  • 储存条件:建议避光、干燥、常温保存;若为防潮包装(MSL),在开封后按对应 MSL 要求进行回流焊。
  • 测试与验证:建议在设计验证阶段进行热循环、振动、寿命与光通衰减测试,确保在目标应用中满足可靠性需求。

七、选型建议与注意事项

  • 驱动方式优先选择恒流驱动,若使用电阻限流需考虑电源波动与容差。
  • 在多 LED 阵列设计中注意热管理与分流匹配,避免单点过热导致亮度不均或失效。
  • 若要求严格的颜色一致性或亮度等级,应向供应商索取 bin 信息或样品进行比对。
  • 在对接汽车或医疗等高可靠场景时,请确认是否满足相应行业规范并与厂商沟通定制规格或可靠性验证。

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
