HSMR-C190 产品概述

一、产品简介

HSMR-C190 是 Broadcom(博通)推出的一款蓝色漫散射表面贴装芯片 LED,0603(1608 公制)封装。器件以窄带蓝光发射为主,适用于对体积和视角有严格要求的指示与背光应用。漫散射封装配合大视角设计,能在板面上提供均匀的可见指示效果,便于消费者电子、仪表及物联网终端的整机设计。

二、主要参数(一览)

  • 发光颜色:蓝色(漫散射)
  • 正向压降 Vf:3.4 V(典型)
  • 额定正向电流 If:20 mA
  • 最大/额定功率:78 mW(规格标注)
  • 在 If 时的典型电功率:3.4 V × 20 mA ≈ 68 mW
  • 峰值波长:469 nm
  • 名义波长:473 nm
  • 发光强度:55 mcd(典型测试条件下)
  • 发光角度:155°(宽视角)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:0603(1608 公制)漫散射芯片
  • 品牌:Broadcom(博通)

三、电学与光学性能说明

HSMR-C190 在典型 20 mA 驱动条件下表现稳定,正向压降约 3.4 V,发光强度 55 mcd(需参照厂方测试条件)。峰值发射约在 469 nm 附近,名义波长 473 nm,属近海洋蓝到纯蓝范围。155° 的半值角说明漫散射透镜提供了极宽的视场,适合做面光或广角指示。

需要注意的是:标称功率 78 mW 与 20 mA 工作时的实际耗能(≈68 mW)存在差异,通常可理解为器件允许的最大功耗边界与典型工作功耗之别。设计时应以最大允许功耗与环境温度、散热条件共同进行热平衡评估。

四、封装与机械特性

0603(1608)超小型 SMD 封装,适合高密度 PCB 布局与自动化贴装。漫散射外观能减少点光源直视眩光并提升板上可视均匀性。由于封装体积小,注意焊盘设计和回流焊工艺以确保可靠焊接并避免热应力损伤。

五、使用建议与常见计算

  • 驱动器选择:建议使用恒流驱动或串联限流电阻来稳定 LED 电流,避免过驱。
  • 限流电阻计算公式:R = (Vs − Vf) / If。举例:
    • 供电 5.0 V 时,R ≈ (5.0 − 3.4) / 0.02 = 80 Ω(常用 82 Ω)
    • 供电 12 V 时,R ≈ (12 − 3.4) / 0.02 = 430 Ω(常用 430 Ω 或 432 Ω)
    • 如果供电电压低于 3.4 V(例如 3.3 V),无法直接驱动该 LED,需提升供电电压或采用升压恒流源。
  • 热管理:尽管单颗功耗较低,但在高密度布局或高环境温度下应考虑电路板散热能力并进行必要的电流降额。
  • 焊接与搬运:遵循常规 SMD 回流焊工艺与 ESD 防护措施,避免长期高温或湿热环境贮存。

六、典型应用场景

  • 消费电子指示灯(电源、状态指示)
  • 仪表面板与医疗设备指示
  • 可穿戴与便携终端的状态提示
  • 交通/安防信号与近距离标识
  • 物联网设备与智能家居的视觉提示

七、环境适应性与可靠性要点

HSMR-C190 的工作温度范围为 -40 ℃ 至 +85 ℃,覆盖绝大多数工业与民用场景。设计时需考虑高温下的光输出衰减与颜色漂移,并对长期工作环境下的电流进行适当降额以延长寿命。建议在成品可靠性验证阶段执行焊接可靠性、湿热、温循环与寿命测试,以确认在特定整机条件下的表现。

八、选型与采购注意

在选型阶段请对比所需色点、亮度与视角需求,确认 55 mcd(典型)是否满足可视要求;若需更高亮度或更窄视角,应查看 Broadcom 的其他蓝色系列产品或联系供应商索取完整数据手册。批量采购前建议获取样品并在目标板上验证焊接、亮度与热特性。

如需更详细的电光数据、典型波形与封装尺寸图,请参考 Broadcom 官方数据手册或联系授权分销商获取完整规格说明。

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
