YLM9070-302T共模滤波器产品概述

一、产品定位与核心功能

YLM9070-302T是益嘉源(YJYCOIN)推出的表面贴装式共模滤波器,专为抑制电子电路中的共模电磁干扰(EMI)设计,可有效过滤电源线路、信号线路中的共模噪声,提升设备的电磁兼容性(EMC)。该器件采用双路通道设计,兼顾滤波性能与电路兼容性,适配中小功率电子系统的干扰抑制需求,是消费电子、工业控制等领域的实用型EMI解决方案。

二、关键性能参数详解

1. 电气性能核心指标

  • 通道数:2:双路并行滤波设计,可同时对两路电源或信号线路进行共模干扰抑制,无需额外并联器件,简化电路布局,提升设计效率。
  • 额定电流:3A:支持中小功率电路(如12V/24V直流电源系统)的连续工作,满足消费电子、工业控制等场景的电流需求,避免因电流过载导致滤波性能衰减。
  • 共模阻抗:3kΩ@100MHz:在100MHz高频频段(常见EMI干扰集中区)具有高阻抗特性,可显著衰减共模噪声,有效解决高频干扰导致的信号失真、设备误触发问题。
  • 额定电压:80V:适配低压直流系统,覆盖大部分消费电子、通信设备的电源电压范围,无需额外降压/升压转换,降低电路复杂度。
  • 直流电阻(DCR):70mΩ:低DCR设计可有效降低器件自身功耗,减少发热,提升系统整体效率,避免因长期发热导致的性能不稳定。
  • 绝缘电阻:10MΩ:满足电气绝缘要求,防止线路间短路,保障设备安全稳定运行,符合基本安规标准。

2. 环境适应性参数

  • 工作温度:-30℃~+100℃:宽温范围覆盖户外低温环境(如北方冬季户外设备)、工业高温场景(如电机控制柜),满足极端环境下的可靠性需求,减少环境温度对性能的影响。

三、封装与可靠性设计

YLM9070-302T采用SMD表面贴装封装,尺寸为9×7×4.8mm,具有以下设计优势:

  • 小型化适配:紧凑尺寸适配高密度PCB布局,节省电路空间,满足便携式设备(如智能手机充电模块)、小型化电子模块的设计需求。
  • 自动化兼容:表面贴装工艺支持SMT自动化生产,提高生产效率,降低人工成本,适合批量制造场景。
  • 可靠性保障:封装材料具备良好的耐温、耐湿性能,配合宽温工作范围,可长期稳定工作于复杂环境,降低器件故障率。

四、典型应用场景

该器件适用于多个电子领域的共模干扰抑制,典型场景包括:

  1. 消费电子:智能手机、平板、笔记本电脑的充电电路,过滤电源线上的高频共模噪声,提升充电稳定性与信号质量,避免干扰影响音频、数据传输。
  2. 工业控制:PLC、伺服驱动器、变频器的电源线路,抑制电机运行产生的电磁干扰,避免影响周边敏感电路(如传感器、控制模块)。
  3. 通信设备:路由器、交换机、基站的电源与信号线路,过滤高频干扰,保障数据传输的稳定性,减少丢包、误码问题。
  4. 汽车电子:车载信息娱乐系统、车身控制器的电源线路,适应车载-40℃~+85℃的温区要求,提升系统抗干扰能力,避免电磁干扰导致的车载设备异常。

五、选型与应用注意事项

  1. 电流负载限制:实际工作电流需低于额定3A,若需更高电流,需并联多器件或选择更高规格产品,避免器件饱和导致滤波性能下降。
  2. PCB布局建议:尽量靠近干扰源(如电源输入端口)或负载端,减少线路寄生干扰;避免与高频信号线路平行布线,防止串扰。
  3. 焊接工艺要求:参考SMD焊接规范(如回流焊温度不超过260℃,焊接时间不超过10秒),避免过温损坏器件内部结构。
  4. 安规匹配:需结合设备整体安规要求,确保绝缘距离、爬电距离符合相关标准(如GB 4943),避免安全隐患。

YLM9070-302T凭借高性价比、宽温适配、低功耗等优势,成为中小功率电子系统EMI抑制的优选器件,可有效提升设备的电磁兼容性与可靠性。

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
