PDSQAT2418-203MLB 为谱罗德(PROD)出品的插件式共模滤波器(共模扼流圈),双通道设计,标称共模电感 20mH(测试频率 1kHz),直流电阻(DCR)约 60mΩ,额定电流 4.5A。耐电压(隔离耐受)达 1kV,绝缘电阻 ≥100MΩ。工作温度范围 -40℃ 至 +105℃。外形尺寸约 24 × 31.5mm,适用于通过孔(THT)安装。
适用于开关电源(SMPS)、交流/直流输入滤波、通信设备、工业控制器、LCD/LED 驱动电源、车载电子(需注意车规认证要求)等场景,用于抑制供电线或信号线的共模干扰,改善电磁兼容(EMC)性能,降低整机辐射与传导噪声。
选择时应综合考虑工作电流、连续电流下电感衰减、工作温度与环境湿度及振动强度。若电路中存在较大直流分量或冲击电流,应评估磁芯的直流偏置特性并适当选用额定电流更高的型号。对车规或医疗等高可靠领域,建议向供应商确认相应的认证与试验报告(如温升、耐压、绝缘和寿命测试)。
长期运行时关注器件温升与外观变化,发现异常发热、开裂或焊点松动应及时更换。布线时尽量保持共模扼流圈与敏感器件有一定间距,避免热源直接辐射影响寿命。
总结:PDSQAT2418-203MLB 提供了较高的共模抑制、良好的电气隔离与宽温度适应性,是中低频共模干扰抑制与电源输入滤波的可靠选择。在设计与选型时应结合实际工作电流、温升和应用环境对器件进行合理余量设计。

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.
