HSMC-C191 产品概述
一、产品简介
HSMC-C191 是 Broadcom（博通）推出的一款高视角红色扩散芯片型表面贴装 LED。器件为矩形平顶扩散透镜、白色透镜罩，外观为红色发光，适用于需要高可视性、广视角提示灯和面板指示的应用场景。
二、主要参数
- 制造商：Broadcom Limited
- 型号：HSMC-C191（基本产品编号 HSMC-C191）
- 封装：0603（1608 公制），片式 LED，卷带（TR）包装
- 尺寸：1.60 mm × 0.80 mm；高度（最大）0.60 mm
- 透镜样式：矩形，平顶，白色散射透镜
- 发光颜色：红色（主波长 626 nm，峰值波长 637 nm）
- 光学特性：视角 170°；毫烛光等级 90 mcd（在测试条件下）
- 电气特性：典型正向电压 Vf = 1.9 V（测试电流 20 mA）
- 封装状态：有源
三、光电特性说明
HSMC-C191 在 20 mA 测试电流下具有约 90 mcd 的亮度，配合 170° 的大视角设计，在正面及较大偏角处均有良好可见性。主/峰波长（626/637 nm）保证了典型的红色显示效果，白色散射透镜有助于指示光的均匀分布和减少眩光。
四、封装与机械特性
0603 小封装（1608 公制）体积小、适合高密度 PCB 布局。矩形平顶扩散透镜在外观一致性和视角控制上表现良好。器件为表面贴装类型，兼容常见贴装设备与回流焊工艺。
五、典型应用
- 面板与设备状态指示灯
- 消费电子与移动设备指示
- 物联网设备、穿戴式电子提示灯
- 键盘/背光指示（低功耗指示）
- 电子玩具与一般信号指示
六、使用与焊接建议
- 推荐按器件制造商数据手册提供的回流焊工艺曲线进行焊接；若使用无铅工艺，应遵循典型无铅回流限温与时间。
- 器件存在静电敏感性，建议在防静电环境（ESD）下操作并佩戴防护用品。
- 未使用的卷带请保持原封防潮包装，避免长时间暴露在高湿环境。若开封，应按干燥密封保管建议处理。
七、驱动电路示例与电阻计算
作为指示灯，常用简单的限流电阻驱动。限流电阻 R = (Vsup - Vf) / I。例如：
- 5.0 V 电源，I = 20 mA：R ≈ (5.0 - 1.9) / 0.02 = 155 Ω（可选标准值 150 Ω 或 160 Ω）
- 3.3 V 电源，I = 20 mA：R ≈ (3.3 - 1.9) / 0.02 = 70 Ω（可选 68 Ω）
根据实际需求可降低电流以延长寿命或降低功耗，常见工作电流范围可低于 20 mA。
八、包装与采购注意事项
封装形式为卷带（TR），适合自动贴片生产线。订购与设计时建议参考 Broadcom 官方数据手册以获取详细的焊盘推荐图、精确电气/光学曲线和可靠性规范，确保在目标应用中满足性能与寿命要求。

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.
