FRICM-5020-251共模滤波器产品概述

一、产品定位与核心应用

FRICM-5020-251是长江微电(cjiang)推出的SMD封装双路共模滤波器,核心定位为解决电子设备中电源/信号线路的共模电磁干扰(EMI)问题,尤其适配需要大电流承载、宽温环境稳定工作的场景。产品通过优化阻抗特性与封装设计,平衡了滤波性能、功率容量与空间效率,可帮助终端设备快速满足EMC合规要求,同时降低设计复杂度。

二、关键性能参数解析

产品参数围绕“干扰抑制+功率适配+环境耐受”三大核心设计,关键指标的实际意义如下:

  1. 通道数2:双路并行滤波结构,可同时对两路独立线路(如电源正负极、差分信号)进行共模噪声衰减,适配多线路设计需求;
  2. 额定电流5A:持续工作电流容量满足中小功率电路(如笔记本电源、车载充电器)的电流需求,无需并联多个滤波器,简化布局;
  3. 阻抗250Ω@100MHz:在100MHz频段(WiFi、蓝牙等无线通信干扰的典型频段)具有高共模阻抗,可有效衰减共模噪声(衰减量约15dB以上,实测值依线路匹配略有差异);
  4. 额定电压50V:覆盖直流/交流峰值电压范围,适配大多数消费电子、汽车电子的电源电压(如12V/24V系统、36V工业电源);
  5. 直流电阻(DCR)20mΩ:极低直流损耗,减少功率消耗与发热,提升设备续航(尤其适合电池供电类产品);
  6. 工作温度-40℃~+125℃:工业级宽温范围,可稳定工作于低温环境(如北方户外设备)与高温环境(如车载仪表、工业控制器内部);
  7. 绝缘电阻10MΩ:确保线路间电气隔离可靠,防止短路风险,符合安全标准要求。

三、封装与可靠性设计

产品采用SMD-4P(4引脚贴片)5x5mm封装,具有以下设计优势:

  1. 空间效率:5mm×5mm小尺寸节省PCB布局空间,适配紧凑型设备(如智能手表充电模块、车载OBD诊断器);
  2. 生产适配:SMD封装支持自动化贴装,符合无铅回流焊工艺(峰值温度260℃,满足行业标准),提升生产效率;
  3. 可靠性保障:长江微电采用耐高温环氧树脂封装材料,抗振动冲击性能(满足汽车电子MIL-STD-202标准),宽温下无老化、开裂问题,长期工作失效率低。

四、典型应用场景

FRICM-5020-251的参数特性使其适配多领域应用:

  1. 消费电子:笔记本电脑电源适配器、智能音箱、平板的电源滤波,抑制开关电源的高频噪声,避免干扰无线信号;
  2. 汽车电子:车载USB充电器、LED车灯控制器、胎压监测系统(TPMS),宽温性能适应车内-40℃~+85℃的工作环境;
  3. 工业控制:PLC输入输出模块、伺服电机驱动器、工业传感器,抗车间电磁干扰,提升设备稳定性;
  4. 通信设备:5G小基站、路由器、交换机的以太网接口滤波,减少电磁辐射,满足通信设备EMC标准。

五、选型优势总结

相比同类产品,FRICM-5020-251的核心优势在于性能平衡与场景适配:

  1. 无需妥协:大电流(5A)与高频滤波(250Ω@100MHz)兼顾,无需通过并联滤波器实现大电流,降低成本;
  2. 宽温无压力:-40℃~+125℃覆盖工业、汽车场景,减少环境限制;
  3. 低损耗高效:20mΩ DCR降低发热,提升设备效率(尤其适合电池供电产品);
  4. 品牌可靠:长江微电成熟工艺,批量一致性好,售后保障完善。

该产品已通过RoHS、REACH等环保认证,可直接用于出口产品设计,是中小功率电子设备EMI滤波的高性价比选择。

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
