YI201209U102-1R0T 磁珠产品概述

一、产品核心定位与应用场景

YI201209U102-1R0T是一款0805封装的高频干扰抑制磁珠,针对100MHz频段噪声设计,兼顾中等功率承载能力与宽温可靠性,适用于多场景的EMI(电磁干扰)抑制需求:

  • 消费电子:手机、平板、智能穿戴的电源模块滤波(抑制射频电路与数字电路间的交叉干扰);
  • 汽车电子:车载中控、传感器电路(宽温-40℃~+125℃适配发动机舱等极端环境);
  • 工业控制:PLC、伺服驱动器的数字信号滤波(防止工业噪声影响控制精度);
  • 通信设备:基站射频前端、路由器电源滤波(衰减100MHz左右的杂波信号)。

二、关键性能参数详解

磁珠的核心价值体现在高频阻抗特性与直流损耗控制,本产品参数针对性强:

1. 阻抗与精度

  • 标称阻抗:1kΩ@100MHz(磁珠阻抗随频率变化,100MHz为峰值阻抗频段,可有效衰减该频段的共模/差模噪声);
  • 精度:±25%(行业通用精度,满足多数通用场景需求,无需过度依赖高精度型号)。

2. 直流损耗(DCR)

  • 直流电阻:300mΩ(DCR越小,直流功耗越低);
  • 实际损耗:1A电流下,直流功耗=I²×R=1W×0.3Ω=0.3W,发热可控,不影响电路效率。

3. 电流与温度范围

  • 额定电流:1A(工作温度范围内允许通过的最大直流电流,超过则可能因过热导致阻抗下降);
  • 工作温度:-40℃~+125℃(宽温设计,覆盖汽车级、工业级应用的环境要求)。

4. 基础结构

  • 通道数:1(单通道磁珠,结构简单,适合单点滤波或单路电源/信号干扰抑制)。

三、封装与可靠性设计

1. 封装尺寸

采用0805封装(英制:2.0mm×1.2mm;公制:2012),体积小、重量轻,适配高密度PCB设计(如小型化智能设备、贴片式模块)。

2. 可靠性保障

  • 封装材料:陶瓷-树脂复合结构,耐高温、抗机械应力,兼容回流焊、波峰焊工艺;
  • 焊接可靠性:引脚符合IPC标准,焊点牢固,长期使用无脱落风险;
  • 环境适应性:通过盐雾测试(5%NaCl溶液,48h),抗腐蚀能力满足户外/工业场景需求。

四、品牌与品质保障

本产品由YJYCOIN(益嘉源) 生产,该品牌为国内磁珠领域知名制造商,具备以下优势:

  • 环保认证:符合RoHS 2.0、REACH标准,无铅无卤;
  • 质量体系:通过ISO9001质量管理体系认证,批次一致性达98%以上;
  • 技术支持:提供选型验证、焊接工艺指导,部分场景可定制参数。

五、选型与使用注意事项

1. 阻抗匹配验证

若目标干扰频率偏离100MHz(如80MHz或120MHz),需通过频谱仪测试实际衰减效果,避免选型偏差。

2. 电流降额使用

  • 常温(25℃):建议实际电流≤0.8A(额定电流的80%);
  • 高温(>100℃):建议降额至0.6A,防止过热失效。

3. 布局与焊接建议

  • 布局:磁珠尽量靠近干扰源(如电源输入、芯片引脚),减少布线长度;
  • 焊接:回流焊峰值温度≤245℃,时间<30s;波峰焊温度≤260℃,时间<5s,避免过焊损坏封装。

4. 并联/串联场景

  • 若需更高阻抗(如2kΩ),可将2个同型号磁珠串联;
  • 若需更大电流(如2A),可将2个同型号磁珠并联(注意阻抗变为500Ω@100MHz)。

总结

YI201209U102-1R0T是一款高性价比的通用型磁珠,兼顾高频滤波、中等功率承载与宽温可靠性,适配消费电子、汽车电子、工业控制等多领域,是PCB设计中抑制100MHz频段噪声的优选元件。

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
