YI201209U201-4R0T磁珠产品概述

YI201209U201-4R0T是益嘉源(YJYCOIN)推出的一款0805封装高频电磁干扰抑制磁珠,专为大电流场景下的电源/信号线路噪声过滤设计,平衡了高频干扰抑制能力与低直流损耗特性,适用于多种工业、消费及通信类电子设备。

一、产品核心特性定位

该磁珠的核心设计围绕「高频噪声抑制+大电流承载+低损耗」三大需求展开:

  • 针对100MHz左右的高频干扰提供明确的阻抗抑制(200Ω@100MHz);
  • 支持最大4A直流电流持续工作,适配电源模块等大电流回路;
  • 低直流电阻(35mΩ)减少电流通过时的功率损耗,避免设备过热。

二、关键参数详解

1. 高频阻抗特性

在100MHz频段下阻抗为200Ω,误差范围±25%(即150Ω~250Ω)。该参数是磁珠抑制EMI的核心指标:100MHz是电子设备中常见的干扰频段(如开关电源纹波、射频电路杂散),200Ω的阻抗可有效衰减该频段的噪声信号,提升电路抗干扰能力。

2. 直流特性

  • 直流电阻(DCR):35mΩ:低DCR意味着电流通过时的压降小(U=I×R),4A电流下仅产生0.14V压降,功率损耗仅0.56W,避免磁珠自身发热影响可靠性;
  • 额定电流:4A:指磁珠在25℃环境下可长期持续工作的最大直流电流,若环境温度升高需降额使用(常规磁珠温度每升高10℃,额定电流约降额10%)。

3. 通道与封装

  • 单通道设计,适配常规单端线路滤波;
  • 封装为0805(英制)/2012(公制),尺寸为2.0mm×1.2mm×0.8mm(典型值),符合小型化电子设备的布局要求。

三、典型应用场景

该磁珠因兼顾大电流与高频抑制,主要应用于以下场景:

  1. 消费电子电源模块:笔记本电脑、平板电脑的DC-DC转换电路,滤除开关电源产生的100MHz左右纹波噪声;
  2. 工业控制设备:PLC、变频器的电源输入/输出线路,抑制工业环境中的电磁干扰,保障控制信号稳定;
  3. 通信基站设备:基站电源的滤波回路,衰减射频杂散干扰,提升信号传输质量;
  4. 车载电子辅助电路:车载充电器、中控系统的电源线路(工作温度范围适配车载环境)。

四、环境适应性

  • 工作温度:-40℃+125℃,覆盖工业级(-40+85℃)及部分汽车级(-40~+125℃)场景;
  • 存储温度:-55℃~+150℃,可耐受极端存储环境;
  • 湿度要求:95%RH以下(非凝结状态),适应潮湿环境。

五、品牌与可靠性说明

益嘉源(YJYCOIN)是国内专注于被动元器件研发生产的品牌,该磁珠通过以下可靠性测试:

  • 温度循环测试(-40℃~+125℃,循环100次);
  • 焊接可靠性测试(回流焊温度曲线);
  • 湿度老化测试(85℃/85%RH,1000小时);
    符合RoHS环保标准,无铅无卤,满足绿色电子设计需求。

该产品通过平衡高频抑制与大电流承载能力,成为中小功率电子设备EMI滤波的实用选择,适配多种复杂应用场景。

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
