PDMCAT16128-103ML是谱罗德(PROD) 推出的一款插件式双路共模滤波器,专为中功率、高电压场景下的电磁干扰(EMI)抑制设计。其核心功能是过滤电路中的共模噪声(即两根导线同时相对于地的干扰信号),减少电磁辐射与传导干扰,帮助设备满足EMC认证要求;同时具备高耐压、低损耗、宽温适应等特点,适配工业控制、电源系统等严苛应用环境。
该产品的电气参数精准匹配工业级需求,核心参数及实际意义如下:
共模电感值:10mH@1kHz
在1kHz频段(低频干扰的典型范围,如电网波动、设备开关噪声)提供10mH的共模电感,能有效衰减低频共模噪声,避免干扰设备正常工作(如PLC误触发、通信信号畸变)。
额定电流:3A
持续工作电流达3A,覆盖中小功率设备(如小型变频器、PLC电源、1kW以内开关电源)的常规负载需求,无需额外降额设计,降低系统设计复杂度。
耐压性能:600VAC/3秒
额定AC电压600V,耐高压测试通过600VAC持续3秒,绝缘性能可靠——适配三相AC 380V系统时,安全裕量充足(约1.5倍),可应对电网瞬态过压风险。
直流电阻(DCR):75mΩ
极低的直流电阻意味着功耗低、发热小:按额定电流3A计算,功耗仅为(I^2R=3^2×0.075=0.675W),连续工作时温升可控(≤10℃),无需额外散热片,节省系统空间。
双路通道
支持双端共模滤波,可直接匹配AC输入电路(L/N线)或双路DC电路,安装灵活,无需额外并联组件。
封装与安装
采用插件式封装,尺寸为20×18mm,体积紧凑,可直接焊接于PCB板;插件结构无需复杂的表面贴装设备,适合批量生产,且焊接可靠性高(抗振动性能优于贴片),适配工业现场的振动环境。
宽温工作范围
工作温度覆盖(-25℃~+85℃),可适应户外低温(如北方冬季)、工业现场高温(如变频器柜内)等极端环境,满足不同地域与场景的应用需求。
可靠性设计
封装采用耐高温环氧树脂,结合高压测试验证,确保长期工作中绝缘性能不衰减;电感绕组采用高强度漆包线,抗老化性能优异,降低设备故障风险。
PDMCAT16128-103ML的参数特性使其适配以下核心场景:
该产品通过了基础EMC测试验证,能帮助设备快速满足GB/T 18245等国内EMC标准,是工业级设备电源滤波的高性价比选择。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
