FRICM-5020-101是长江微电推出的SMD贴片式双路共模滤波器,专为抑制电子电路中的共模电磁干扰(EMI)设计,兼具中功率承载能力与高密度集成特性。产品核心解决“电路干扰超标+空间受限+宽温环境需求”的痛点,广泛适配消费电子、通信、汽车及工业领域的中功率电路模块,是实现EMC合规性的关键元件之一。
共模滤波器的核心是特定频率下的共模阻抗,该产品在100MHz频段(开关电源谐波、通信射频干扰的典型频段)提供100Ω阻抗,可有效衰减共模干扰信号,帮助电路通过EN55032、CISPR 22等EMC标准测试。
极低的DCR可显著降低功率损耗:当负载电流为6A时,单通道功率损耗仅0.468W,双路并联时损耗更低,避免元件发热影响电路可靠性,适合长期连续工作场景。
在25℃/500V DC条件下绝缘电阻≥10MΩ,确保电路间电气隔离,防止共模干扰串扰至信号处理等敏感模块。
产品采用SMD-4P(4引脚贴片封装),尺寸为5mm×5mm×2.0mm(长×宽×高),符合行业贴片封装规范:
FRICM-5020-101的性能匹配多领域中功率电路需求,典型应用包括:
产品工作温度范围为**-40℃~+125℃**,满足极端环境需求:
该产品凭借“高性能抑制+低损耗+宽温适配”的综合优势,成为中功率电路EMI治理的高性价比选择。

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.
