CUW43T-513T-AU 共模滤波器产品概述

一、产品定位与核心类别

CUW43T-513T-AU是奇力新(Chilisin)推出的小型化表面贴装(SMD)共模滤波器,核心作用是抑制电子电路中的共模电磁干扰(EMI),同时保留差模信号传输。其4.5×3.2mm的紧凑封装,兼顾了滤波性能与安装空间效率,主要适配低功耗、高密度PCB设计的场景,是消费电子、IoT终端、汽车电子等领域的常用滤波器件。

二、核心电性能参数详解

该产品的电性能参数针对实际应用场景做了精准优化,关键参数的实际意义如下:

  1. 电感值:51μH@100kHz
    在100kHz频段(开关电源、DC-DC转换器的典型噪声频段)提供稳定的共模电感,可有效阻挡该频段的干扰信号进入敏感电路;
  2. 额定电流:200mA
    适配低功耗电路(如IoT传感器、小型控制器),满足大多数便携式设备的工作电流需求,无需额外降额设计;
  3. 高频阻抗:2.8kΩ@10MHz
    在10MHz高频段具备较强的共模干扰抑制能力,覆盖蓝牙、WiFi等无线通信的部分干扰频段,减少射频模块的信号串扰;
  4. 电压规格:额定电压50V、耐电压125V
    额定电压覆盖常规直流电源(如12V、24V系统),耐电压125V(是额定电压的2.5倍)可应对电源波动或瞬态过压,提升电路可靠性;
  5. 直流电阻(DCR):1Ω
    直流损耗低,减少电源路径的能量损失,尤其适合电池供电设备延长续航时间(如智能手表、无线耳机);
  6. 工作温度范围:-40℃~+125℃
    覆盖宽温环境,可用于汽车发动机舱、工业现场等温度变化剧烈的场景,无需额外温度补偿。

三、封装与典型应用场景

  1. 封装特性:
    采用SMD 4.5×3.2mm小型贴片封装,无引线设计,支持自动化贴装,适配高密度PCB布局(如智能手机主板、IoT模块),可节省30%以上的安装空间;
  2. 典型应用:
    • 消费电子:智能手机、平板电脑的充电电路滤波,抑制电源噪声对射频模块的干扰;
    • IoT终端:智能家居传感器、可穿戴设备的信号滤波,平衡小体积与EMI抑制需求;
    • 汽车电子:车载小型控制器(座椅调节、车窗控制)的电源滤波,宽温范围满足车载环境要求;
    • 工业控制:小型PLC、传感器节点的信号滤波,提升工业现场的抗干扰能力。

四、性能优势与设计特点

该产品在性能与实用性上具备以下突出特点:

  1. 宽频段覆盖:同时兼顾100kHz(开关电源噪声)和10MHz(无线干扰)频段,无需并联其他滤波器,简化电路设计;
  2. 低损耗设计:DCR仅1Ω,直流损耗远低于同类常规产品,减少电池供电设备的静态功耗;
  3. 高可靠性:耐电压125V、宽温范围覆盖极端环境,经振动、湿度测试验证,可稳定工作于 harsh 场景;
  4. 小型化适配:4.5×3.2mm封装可直接替换传统较大体积的共模滤波器,无需调整PCB布局,提升产品迭代效率。

五、可靠性验证与环境适应性

奇力新对该产品的可靠性做了严格测试,确保符合工业级应用要求:

  • 温度循环测试(-40℃~+125℃,循环1000次):验证宽温下的电感值、DCR无衰减;
  • 过压测试(125V持续1分钟):确认耐电压能力符合规格;
  • 振动测试(符合IPC-9701标准):验证贴片封装在10Hz~2000Hz振动下的可靠性;
  • 湿度测试(85℃/85%RH,1000小时):确保高湿环境下的绝缘电阻无下降。

总结

CUW43T-513T-AU共模滤波器通过紧凑封装、宽频段滤波、低损耗设计,精准匹配低功耗小型化设备的EMI抑制需求,同时具备宽温、高耐压等可靠性特点,是奇力新在滤波器件领域的成熟产品,可广泛应用于消费电子、IoT、汽车电子等多个领域。

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.
