PCAQ1211MW-202 是谱罗德(PROD)推出的一款表面贴装式共模滤波器,适用于双通道线路的共模干扰抑制。器件额定电流为4A,额定电压与耐电压均为125V,适配一般低压电源及信号线的电磁兼容(EMC)处理需求。封装尺寸为12.0 × 10.8 × 6.4 mm,体积紧凑,便于高速线路与开关电源的板级布局。
适用于需抑制共模干扰的双通道电源和信号线,典型应用包括但不限于:
器件为 SMD 封装(12×10.8×6.4 mm),建议贴片在干扰源与接口之间靠近接口侧放置,以缩短共模回路环路,增强滤波效果。布线时保证两路线对称通过器件,地线回流路径应尽量短且低阻,以避免将共模能量转为差模辐射。对于接近额定电流使用场景,需考虑散热与周边元件留有足够空隙。
如需样品、详细电气特性曲线或阻抗随频率变化的数据,请联系谱罗德(PROD)或其授权代理获取完整数据手册与应用资料。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
