YLM9070-701T共模滤波器产品概述

一、产品定位与核心价值

YLM9070-701T是益嘉源(YJYCOIN)推出的双路表面贴装共模滤波器,专为中功率电路的共模电磁干扰(EMI)抑制设计。其核心价值在于平衡了「高噪声抑制能力」与「低功率损耗」,以紧凑封装适配高密度PCB布局,可帮助设备快速满足EMC认证要求,广泛覆盖电源滤波、差分信号传输等场景。

二、关键性能参数详解

该产品的核心参数直接支撑应用性能,具体解读如下:

  1. 通道数:2
    双路并行设计,适配差分信号(如USB、以太网)或双电源回路,无需额外并联元件即可实现多路共模抑制,简化电路设计。
  2. 额定电流:5A(持续)
    满足中功率设备(如LED驱动、小型开关电源)的持续工作需求,避免过载导致的性能衰减或元件损坏。
  3. 共模阻抗:700Ω@100MHz
    这是抑制共模噪声的核心指标——100MHz是EMI测试的关键窗口,700Ω的高阻抗可有效衰减该频段内的共模干扰,降低设备对外辐射与传导噪声。
  4. 额定电压:80V DC/AC
    覆盖多数中低压电路(如12V/24V电源、车载12V系统),满足基本电气安全要求,避免过压击穿。
  5. 直流电阻(DCR):10mΩ(典型值)
    极低DCR大幅减少功率损耗(5A时仅0.25W),降低元件发热,提升系统效率与长期可靠性。
  6. 绝缘电阻:≥10MΩ(100V DC)
    保证两路通道与地之间的电气隔离,避免短路或信号串扰,提升电路稳定性。

三、封装与物理特性

YLM9070-701T采用SMD表面贴装封装,尺寸为9.0mm×7.0mm×4.8mm(长×宽×高),具备以下优势:

  • 小体积适配高密度设计:适合笔记本电脑、车载中控、工业控制模块等空间受限设备,不占用过多PCB面积。
  • 自动化生产兼容:标准SMD封装支持回流焊、波峰焊等工艺,提升生产效率与批量一致性。
  • 抗振动可靠性:封装引脚设计合理,焊接后可承受工业/车载环境的振动冲击,降低失效风险。

四、典型应用场景

结合参数特性,该产品的核心应用场景包括:

  1. 开关电源滤波:用于LED驱动电源、小型AC-DC电源的EMC整改,抑制开关管产生的100MHz左右共模噪声。
  2. 差分信号传输:适配USB 2.0/3.0、HDMI、以太网等接口,减少信号线上的共模干扰,提升传输稳定性(如避免HDMI画面闪烁)。
  3. 车载电子系统:车载USB充电口、中控显示屏电源滤波,满足车载宽温(-30℃~100℃)与EMC法规要求。
  4. 工业控制设备:PLC、传感器模块的电源与信号滤波,避免工业环境电磁干扰影响设备精度(如传感器误触发)。

五、可靠性与环境适应性

该产品的环境适应性与可靠性表现如下:

  • 宽温工作范围:-30℃~+100℃,覆盖北方户外低温、密闭机箱高温等场景,无需额外散热设计。
  • 环保合规:符合RoHS无铅要求,适配全球市场准入(如欧盟CE、中国CCC)。
  • 长期可靠性:经过老化测试与振动测试,典型平均无故障时间(MTBF)≥10万小时,适合工业级长期运行需求。

六、应用与选型注意事项

  1. 电流/电压降额:实际工作电流需≤5A(峰值电流建议降额30%),工作电压≤80V,避免过流/过压损坏。
  2. 焊接工艺:回流焊峰值温度控制在230℃~250℃(时间≤30s),避免高温导致封装变形或性能衰减。
  3. PCB布局:尽量靠近干扰源(如开关电源输出端),引脚与地之间预留≥0.5mm间距,防止短路。
  4. 差模配合:若需同时抑制差模噪声,可配合X电容(如0.1μF/100V)使用,提升整体滤波效果。

综上,YLM9070-701T以「高抑制、低损耗、小体积」为核心优势,是中功率电路EMI整改的高性价比选择。

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.
