FM-B1921RGBA-SH 产品概述
一、产品简介
FM-B1921RGBA-SH 为国星光电推出的共阳极表面贴装小型RGB发光二极管，封装尺寸约 2.1×2.2mm（SMD），体积紧凑（长 2.15mm、宽 2.05mm、高 1.9mm），发光角度 110°，适合高密度安装与小型化背光、指示与显示应用。
二、光学与电气特性（典型值）
- 波长：R 624nm；G 525nm；B 474nm。
- 正向电流（额定）：R 15mA；G 8mA；B 5mA。
- 正向压降（Vf）：R 2.1V；G 2.8V；B 2.8V。
- 发光强度（典型）：R 260mcd；G 405mcd；B 60mcd（在各自额定电流下）。
- 功率（典型）：R 60mW；G 90mW；B 90mW。
- 工作温度范围：-30℃ ~ +85℃。
- 引脚配置：共阳极（便于多通道驱动和矩阵扫描）。
三、应用建议
- 适用于便携式设备指示灯、状态显示、装饰照明、按键背光、小尺寸显示模组等需要三色混光或单色指示的场合。
- 共阳极设计利于用低侧开关或驱动器实现颜色控制，便于与微控制器或LED驱动芯片配合使用。
- 建议采用限流电阻或恒流驱动，保证各色在额定电流下稳定工作并延长寿命。举例（以 5V 电源为例）：R 通道约 200Ω，G 通道约 270Ω，B 通道约 470Ω（仅供参考，实际按系统电压与所需亮度调整）。
四、封装与可靠性要点
- SMD 正贴封装，推荐按国星光电提供的回流焊工艺规范进行焊接，避免超出推荐温度曲线。
- 工作与存储环境应避免超过额定温度区间并防止长时间湿热与机械冲击。
- 使用时注意静电防护与适当散热安排，尤其在高占空比或连续点亮场景下。
五、总结
FM-B1921RGBA-SH 以小巧的 SMD 封装、共阳极驱动便利性和较宽的发光角度为特点，R/G/B 三色亮度分布均衡，适合嵌入式显示与指示应用。选型时请参考上述电气光学参数并结合实际驱动方案与散热条件进行验证。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
