YLCM0905C-471T共模滤波器产品概述

一、产品核心定位

YLCM0905C-471T是益嘉源(YJYCOIN)推出的一款小型化表面贴装共模滤波器,专为电子电路中的共模电磁干扰(EMI)抑制设计。产品兼顾低频段电感特性与高频段阻抗性能,适配小功率、宽温环境下的电路应用,可有效过滤电源或信号线路中的共模噪声,帮助设备满足EMC电磁兼容标准,降低干扰对电路稳定性的影响。

二、关键电气性能解析

1. 宽频段干扰抑制能力

  • 低频共模电感:1kHz频率下电感值为470uH,可针对性抑制市电频率(50/60Hz)附近的共模干扰,解决电源输入侧的低频噪声问题;
  • 高频阻抗特性:50MHz频率下阻抗达800Ω,对射频范围内的共模噪声(如无线通信干扰、射频辐射)有显著抑制效果,实现低-高频段全覆盖。

2. 电流与电压适配性

  • 额定电流:1.1A,满足小功率电子设备的持续工作需求(如5V/2A电路的单路电流、12V/1A电源系统);
  • 额定电压:50V,覆盖直流或交流峰值电压场景,适配低压电源(12V、24V)、信号线路等常见应用。

3. 低损耗与可靠性

  • 直流电阻(DCR):仅140mΩ,低损耗特性可减少电路发热,提升系统效率,尤其适合对功耗敏感的便携设备(如无线耳机充电盒)或长时间工作的工业电路;
  • 环境与绝缘:工作温度范围-40℃~+80℃(工业级温区),可适应户外、车载等宽温场景;绝缘电阻≥10MΩ,确保电路间电气隔离可靠,防止短路或漏电风险。

三、封装与生产适配性

产品采用SMD小型化封装,尺寸为9.2mm×6mm×5mm(长×宽×高),具备以下优势:

  • 空间节省:适配高密度PCB板设计,适合便携设备、小型模块的紧凑布局;
  • 自动化生产:支持标准回流焊工艺(焊接温度遵循240℃左右峰值曲线),可直接集成到SMT产线,提升生产效率;
  • 机械可靠性:外壳采用绝缘封装材料,抗机械冲击能力强,可耐受运输、安装过程中的轻微振动。

四、典型应用场景

1. 消费电子电源

  • 手机充电器、笔记本适配器、智能音箱、路由器等设备的电源输入线路,过滤市电引入的共模噪声,满足CE、FCC等EMC认证要求;

2. 工业控制设备

  • PLC(可编程逻辑控制器)、传感器节点、小型变频器的信号/电源接口,抑制工业现场的电磁干扰(如电机启动噪声),提升设备稳定性;

3. 通信终端

  • 4G/5G路由器、无线AP的射频前端或电源模块,过滤共模噪声对信号传输的干扰,优化通信质量;

4. 车载低压电路

  • 车载充电器、车载显示屏的辅助电源,适配-40℃~+80℃的车载环境,抑制汽车点火系统、电机产生的电磁干扰。

五、使用注意事项

  1. 电流匹配:电路工作电流需低于1.1A额定值,避免过载导致产品发热或性能下降;
  2. 电压限制:电路峰值电压不得超过50V,防止绝缘击穿;
  3. 封装适配:PCB焊盘尺寸需匹配9.2×6mm封装,确保焊接牢固;
  4. 布局建议:建议靠近干扰源(如电源输入接口、射频天线端)安装,减少干扰耦合路径;
  5. 存储条件:未使用产品需存储在干燥、常温环境(-10℃~+40℃,湿度≤60%),避免受潮影响绝缘性能。

YLCM0905C-471T凭借宽频段滤波、小体积、高可靠性等特点,成为小功率电子设备EMI整改的优选组件,可覆盖消费电子、工业、通信等多领域应用需求。

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
