PCAQ3216B-601ATE 是谱罗德(PROD)推出的一款小型表面贴装共模滤波器(Common Mode Choke),封装形式为 SMD-4P,外形尺寸 3.2 × 1.6 mm。器件为双通道结构,面向需要对共模干扰进行抑制且电流需求较小的信号链路与低功耗电源线路。其典型应用包括移动设备、消费电子、通信模块以及工业控制等对 EMI 抑制和信号完整性有要求的场合。
这些参数表明该器件在高频段具备较高的共模阻抗,适合用来降低 100 MHz 附近的共模干扰,同时低频压降和发热都较小,适用于小电流应用。
注意:由于额定电流为 250 mA,本件不适合作为大电流功率滤波元件,应用于信号线或弱电源路径。
器件 DCR 为 800 mΩ,满载 250 mA 时的功耗约为 I^2·R = 0.0625·0.8 ≈ 0.05 W(50 mW),发热量较小,但在高环境温度或多器件密集布板时仍需注意散热与温升。工作温度范围覆盖 -25 ℃ 至 +100 ℃,适用于常见行业环境。耐压与绝缘电阻指标确保器件在信号隔离与耐压测试中具备可靠性。
小结:PCAQ3216B-601ATE 以其高频共模阻抗、小巧封装和低功耗特性,适合在受限空间内对信号线进行共模干扰抑制。在选型与布局时应综合考虑额定电流、DCR 与工作温度,结合板级测试验证滤波效果。

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.
