YLCM0904-103T 共模滤波器产品概述

一、产品定位与核心功能

YLCM0904-103T是益嘉源(YJYCOIN)推出的贴片式双路共模滤波器,核心作用是抑制电子电路中的共模电磁干扰(EMI),同时保留差模信号的正常传输。产品针对小功率、高密度PCB布局场景优化,可帮助终端设备满足电磁兼容(EMC)标准要求,避免干扰对信号精度、设备稳定性的影响。

二、关键参数深度解析

产品参数围绕“滤波效果、电流承载、环境适应性”三大维度设计,核心参数解析如下:

  1. 共模电感值:10mH@10kHz
    共模电感的感值是滤波性能的核心指标,10kHz频率下10mH的感值,可有效衰减中低频(10kHz~几MHz)的共模干扰(感值与干扰频率成反比,感值越大对低频干扰抑制越强),覆盖多数开关电源、信号电路的干扰频段。
  2. 额定电流:350mA
    连续工作的最大电流容量,满足小功率电路(如5V/1A电源滤波、低功耗传感器模块)的电流需求;若电流超过额定值,磁芯可能饱和,导致滤波性能下降。
  3. 直流电阻(DCR):1.3Ω
    绕组直流电阻极低,350mA电流下功率损耗仅约0.16W,发热控制优异,可长期稳定工作无过热风险。
  4. 绝缘与耐压性能
    • 耐电压250V:满足低压电路(12V/24V直流、110V交流)的绝缘安全要求,具备足够电压裕度;
    • 绝缘电阻100MΩ:绕组与磁芯、引脚间绝缘性能良好,防止漏电,提升电路安全性。
  5. 工作温度范围:-40℃~+125℃
    覆盖工业级宽温场景,可适应户外低温(北方冬季)、工业设备高温(控制柜内部)等极端环境,可靠性突出。

三、封装与工艺特性

YLCM0904-103T采用SMD-4P贴片封装,尺寸仅8.9mm×5.4mm,工艺优势明显:

  1. 高密度布局适配
    小型化贴片设计无需插件焊接,适合自动化贴装生产线,大幅节省PCB空间,尤其适合便携设备、小型模块的紧凑设计。
  2. 稳定的磁芯与绕组工艺
    采用高性能铁氧体磁芯(共模电感常用材料),绕组为细径漆包线绕制,工艺精度高,批量生产感值一致性好;引脚镀锡处理,焊接可靠性强,抗虚焊能力优异。
  3. 抗振动与冲击
    贴片引脚与PCB贴合紧密,相比插件电感抗振动、抗冲击性能更好,适合车载、工业现场等振动环境。

四、典型应用场景

产品因体积小、滤波性能均衡,广泛应用于以下场景:

  1. 消费电子
    小型家电(智能台灯、加湿器、蓝牙音箱)的开关电源滤波,抑制电源高频纹波;便携设备(智能手表、蓝牙耳机)的充电电路滤波,提升电磁兼容性。
  2. 工业控制
    低功率PLC模块、传感器节点(温度/压力传感器)的信号/电源滤波,衰减工业现场电磁干扰;小型工业电源输出端滤波,满足EMC认证要求。
  3. 通信设备
    WiFi、蓝牙、LoRa等无线模块的电源滤波,减少模块辐射干扰,提升通信稳定性;小型路由器、交换机的电源滤波。

五、选型核心优势

相比同类产品,YLCM0904-103T具有三大突出优势:

  1. 性能与体积平衡
    在8.9×5.4mm小体积内实现10mH感值,兼顾滤波效果与空间节省,适合高密度设计。
  2. 宽温可靠性
    -40℃+125℃工作温度范围,远超普通消费级产品(0℃70℃),覆盖工业、户外严苛场景。
  3. 成本可控
    国产益嘉源品牌的高性价比优势,在保证性能稳定的前提下,降低终端产品BOM成本,适合批量应用。

该产品凭借“小体积、宽温、高性价比”的特点,成为小功率电路EMI抑制的优选器件,可满足多数消费电子、工业控制、通信设备的滤波需求。

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
