PROD谱罗德PDMCAT221413-202MLB是一款中大功率插件式共模滤波器,核心作用是抑制电路中的共模干扰(如电网波动、开关器件噪声),帮助设备满足EMC电磁兼容标准。其参数设计精准匹配多类工业及新能源场景,典型应用包括:
该产品围绕“中大功率滤波+高可靠性”需求设计,关键指标具备明确的应用指向性:
共模电感的电感量是干扰抑制的核心,2mH@1kHz覆盖1kHz-1MHz中低频段(共模干扰高发区)。相比小电感产品,2mH可有效衰减电网50/60Hz波动带来的低频共模噪声,且1kHz测试频率下电感值稳定,避免高频饱和。
14A持续额定电流是核心优势,适配中大功率负载。实际应用中,负载电流≤14A时无磁饱和,滤波性能稳定;短期过载(如启动瞬间)可通过磁芯裕量避免性能突变,无需额外降额设计。
1.5kV AC耐压测试(持续3秒) 符合IEC 60950等安规标准,确保高电压环境下绝缘可靠,避免共模高压击穿绝缘层,降低短路风险,适合电网侧或高压输入场景。
15mΩ低DCR 大幅减少热损耗:满载14A时,损耗仅为 ( I^2R = 14^2 \times 0.015 = 2.94W ),发热远低于同类产品。低损耗不仅提升设备效率,还延长产品寿命,适应长时间连续工作。
宽温范围 覆盖工业及户外极端环境:-25℃适配北方冬季户外设备,+105℃承受电源内部高温(如开关器件热辐射),无需额外散热,降低系统成本。
采用28mm×18.5mm插件封装,在保证性能的前提下节省PCB空间,适配紧凑型设备(如车载电源)。插件引脚焊接可靠性高于贴片,适合批量生产中的人工/自动焊接,减少虚焊风险。
绕组与磁芯间采用耐高温绝缘材料包裹,通过1.5kV AC耐压测试;引脚镀锡处理,提升焊接附着力与抗氧化能力,适应潮湿/盐雾环境(需配合防护)。
该产品针对中大功率设备的共模滤波痛点,实现性能与成本的平衡:
产品已通过传导发射等EMC测试,可帮助设备快速通过CE、FCC认证,是工业电源、光伏逆变器、通信设备等领域的高性价比解决方案。
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.
