FRICM-5020-101共模滤波器产品概述

一、产品定位与核心价值

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。

二、关键性能参数解析

1. 共模抑制能力:100Ω@100MHz(核心指标)

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。

2. 功率承载能力:6A额定电流+50V额定电压

  • 6A额定电流:满足DC-DC转换器、小型开关电源、汽车辅助模块等中功率电路的电流需求(峰值电流兼容1.2倍额定值,即7.2A);
  • 50V额定电压:覆盖12V/24V/48V等常见低压直流系统,避免过压击穿风险。

3. 低损耗特性:13mΩ直流电阻(DCR)

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。

4. 绝缘可靠性:10MΩ绝缘电阻

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。

三、封装与物理特性

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:

  • 引脚间距适配0.8mm/1.0mm PCB焊盘,兼容自动化SMT贴装;
  • 小型化设计节省PCB空间,适合路由器主板、车载控制器等高密度集成电路;
  • 封装材料为耐高温环氧树脂,可承受回流焊工艺(峰值温度≤260℃,回流时间≤30s)。

四、典型应用场景

FRICM-5020-101的性能匹配多领域中功率电路需求,典型应用包括:

  1. 通信设备:路由器、交换机、光模块的电源滤波,抑制射频干扰对信号传输的影响;
  2. 汽车电子:车载T-Box、ADAS辅助驾驶模块的12V/24V电源滤波,适应宽温环境;
  3. 工业控制:PLC、伺服驱动器的DC-DC转换电路滤波,减少工业现场电磁干扰;
  4. 消费电子:智能家电(扫地机器人、投影仪)的开关电源滤波,提升EMC合规性。

五、环境适应性说明

产品工作温度范围为**-40℃~+125℃**,满足极端环境需求:

  • 低温场景:户外通信基站、车载冬季低温(-40℃)下稳定工作;
  • 高温场景:工业控制柜、车载发动机舱(125℃)下无性能衰减;
  • 存储温度:-55℃~+150℃,便于供应链存储与运输。

六、选型与使用注意事项

  1. 参数限制:需在额定电流(≤6A)、额定电压(≤50V)范围内使用,避免过流/过压失效;
  2. PCB布局:建议靠近干扰源(如开关电源输出端)或负载端布局,缩短干扰路径;
  3. 焊接工艺:回流焊遵循IPC标准,峰值温度不超260℃,避免多次焊接;
  4. 静电防护:贴片时采用ESD防护,防止静电损坏内部绕组。

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。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
