B32921C3473M189 产品概述
一、产品简介
B32921C3473M189 为 TDK 品牌的安规电容器，属于 X2 类线间抑制用电容。标称电容值 47nF，容差 ±20%，额定工作电压（AC）305V，工作温度范围 -40℃ 到 +110℃，为插件径向引线封装，导脚间距 P=10mm。该器件专为工频交流电网的 EMI/RFI 抑制与跨线滤波设计，满足对人员和设备安全性的严格要求。
二、主要特性
- 容值：47nF（0.047µF），精度 ±20%
- 安规等级：X2（线对线）适用于跨线连接的抑制场合
- 额定电压：305VAC（工作电压）
- 工作温度：-40℃ ~ +110℃
- 封装形式：径向引线（插件），引脚间距 P = 10mm，便于通孔安装和自动化插件
- 品牌：TDK，工业级可靠性和一致性
三、典型应用场景
- 电源输入端的 EMI/RFI 抑制（跨火线与零线）
- 开关电源（SMPS）输入滤波与共模/差模抑制电路
- 家用电器、照明设备、功率控制器中的干扰抑制
- 工业控制、变频器、逆变器、电机驱动等对抗电网干扰的电路
- 任何要求 X2 安规电容器以满足安全标准的线路级滤波场合
四、安装与使用注意事项
- 按照电路板设计要求保证足够的爬电距离和电气间隙，X2 器件虽适用于跨线，但仍需满足所适用的安全标准和实际应用的间隙要求。
- 该为插件（通孔）封装，焊接时避免长时间高温接触以防内部材料热损伤；建议采用推荐的焊接曲线与工艺。
- 在使用中若需放电，建议并联放电电阻以保证断电后电容快速安全放电，避免触电风险。
- 不建议用作直流高压能量储存元件或高频谐振计时元件，其主要用途是交流线路的抑制与滤波。
- 避免在超过额定温度或长时间潮湿环境下使用；如需户外或恶劣环境使用，请评估额外防护措施。
五、存储与包装
- 建议在清洁、干燥、避免直接阳光照射的环境中存放，温度与湿度控制在器件规范范围内以延长寿命与保持电气特性稳定。
- 一般采用卷盘或托盘包装，便于自动化装配；运输过程中避免机械冲击与挤压。
六、小结
B32921C3473M189 是一款面向电网干扰抑制的高可靠性 X2 安规电容，47nF 的容值与 ±20% 的容差适合常见的输入滤波和跨线抑制需求。其径向插件（P=10mm）形式便于通孔装配，工作温度范围宽，适用于家电、工业与电源类产品中对安全性与电磁兼容性有要求的场合。在设计与使用中，应遵循安规间隙要求、合适的焊接工艺与必要的放电保护，以确保长期可靠运行。

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.
