YI201209U101-6R0T 磁珠产品概述

一、产品基本信息

YI201209U101-6R0T是益嘉源(YJYCOIN) 推出的一款贴片磁珠,核心功能为电路电磁干扰(EMI)抑制。产品采用0805封装(英制尺寸,对应公制2012),属于小型化表面贴装元件,适配高密度PCB设计需求。型号中“2012”对应封装尺寸,“101”表示100Ω(@100MHz)阻抗,“6R0”代表6A额定电流,清晰体现核心参数特征,是中大功率电路滤波的优选元件。

二、核心电气参数详解

磁珠性能的核心围绕高频阻抗、直流损耗、电流承载能力展开,本产品关键参数及意义如下:

  1. 高频阻抗:100Ω±25%(@100MHz)—— 磁珠阻抗随频率变化,100MHz是电子设备中常见干扰频段(如开关电源噪声、射频杂波),该阻抗值可针对性抑制此频段电磁干扰;
  2. 直流电阻(DCR):20mΩ—— 低DCR意味着直流电流通过时损耗极小,避免磁珠自身发热导致电路效率下降;
  3. 额定电流:6A—— 持续工作的最大允许电流,是大电流电路滤波的核心指标,保证6A负载下磁芯不发生饱和,性能稳定;
  4. 工作温度范围:-40℃~+125℃—— 覆盖工业级应用温度区间,适应极端环境(如低温户外、高温电源内部)的长期工作。

三、典型应用场景

结合产品“大电流、宽温、小型化”特点,主要适用于以下场景:

  1. 电源滤波:DC-DC转换器输出端、服务器/充电器等大电流电源线路,过滤开关噪声,提升电源质量;
  2. 工业控制设备:PLC、变频器等工业设备的信号/电源线路,应对车间复杂电磁环境,同时适配-40℃~+125℃宽温工况;
  3. 汽车电子:车载电源、传感器线路的EMI防护(宽温特性满足基础汽车级应用需求);
  4. 通信设备:路由器、基站射频周边电路,抑制100MHz频段杂波,保证信号传输质量;
  5. 消费电子:笔记本电脑、显示器电源模块,在小型化PCB中实现高效滤波,不占用额外空间。

四、性能优势与特点

  1. 低损耗高效:20mΩ DCR大幅降低直流功耗,避免磁珠发热,提升电路整体效率;
  2. 针对性干扰抑制:100Ω@100MHz阻抗匹配常见干扰频段,抑制效果明确;
  3. 大电流承载:6A额定电流满足多数中大功率电路需求,无需并联多颗磁珠,节省PCB空间;
  4. 宽温可靠:-40℃~+125℃工作范围,保证极端环境下性能稳定;
  5. 小型化集成:0805封装适配高密度设计,符合现代电子设备小型化趋势。

五、使用注意事项

  1. 电流裕量:实际工作电流建议不超过额定电流的80%(≤4.8A),避免长期过载导致磁芯饱和;
  2. 焊接工艺:回流焊需遵循0805封装标准曲线(峰值温度240℃~260℃,时间≤10s),防止焊接损伤;
  3. 布局建议:磁珠靠近噪声源(如开关管)或负载端,减少寄生耦合,提升滤波效果;
  4. 频率匹配:若干扰频率偏离100MHz,需通过 datasheet 确认对应阻抗值,确保抑制效果;
  5. 存储防护:存储温度-55℃~+150℃,湿度≤90%非凝结,避免引脚氧化影响性能。

本产品凭借明确的参数指标和实用的性能特点,可广泛应用于需大电流滤波与EMI抑制的各类电子设备,是工业、通信、消费电子领域的可靠选择。

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
