CBG100505U301T 片式磁珠产品概述

一、产品基本信息

CBG100505U301T是风华高科(FH品牌) 推出的单通道片式磁珠,型号命名清晰对应核心特性:

  • 「100505」:封装标识,对应英制0402(公制1005),尺寸为1.0mm×0.5mm×0.5mm,属于超小型片式封装;
  • 「U301T」:阻抗特性标识,代表100MHz频率下阻抗300Ω(±25%误差)。

该产品定位为通用型EMI/RFI滤波元件,专为低电流、高密度电路设计,可覆盖消费电子、通信、工业控制等多领域的噪声抑制需求。

二、核心电气参数解析

磁珠的性能核心在于「直流损耗小、交流干扰抑制强」,该产品关键参数如下:

1. 阻抗特性(300Ω@100MHz ±25%)

磁珠阻抗随频率呈「低频低阻、高频高阻」特性,100MHz是射频干扰(如WiFi、蓝牙杂散)的典型频段。300Ω的阻抗可有效衰减该频段内的噪声信号,同时避免对低频有用信号(如音频、直流电源)的干扰。±25%的误差范围符合通用型元件的量产标准,可满足多数常规应用。

2. 直流电阻(DCR:800mΩ)

低DCR是该产品的核心优势之一:800mΩ的直流电阻意味着在直流信号传输路径中,压降和功耗极小(如100mA电流下,压降仅0.08V),适合对电源效率要求高的便携式设备(如智能手机、无线耳机),避免因磁珠损耗影响电池续航。

3. 额定电流(100mA)

连续工作额定电流为100mA,是磁珠允许的最大直流电流(无明显性能衰减)。应用时需确保电路工作电流不超过该值,否则可能导致磁珠过热、阻抗漂移甚至失效——这一参数适配多数低功耗电路(如传感器、音频模块),但需注意大功率场景需选择更高额定电流的型号。

三、典型应用场景

该磁珠针对低电流、高频干扰抑制场景优化,主要应用包括:

1. 消费电子终端

  • 智能手机/平板:音频电路、射频前端滤波(抑制WiFi/蓝牙杂散),保证音质纯净与信号稳定;
  • 无线耳机:充电电路与信号线路滤波,降低电磁噪声对音质的影响;
  • 智能穿戴:手表/手环的传感器接口滤波,防止环境噪声干扰健康数据采集。

2. 通信设备

  • 路由器/交换机:以太网端口信号滤波,抑制高速数据传输中的EMI,降低误码率;
  • 小型基站:射频模块滤波,优化信号质量,减少邻道干扰。

3. 工业控制与物联网

  • PLC/传感器模块:工业现场传感器接口滤波,避免电机、电网噪声影响数据精度;
  • 智能家居:智能插座、灯光控制器的电源线路滤波,提升设备抗干扰能力。

4. 汽车电子(低功耗场景)

  • 车载显示屏:背光驱动电路滤波,适配车载环境温度与电磁干扰;
  • 胎压监测:传感器信号线路滤波,保证数据传输稳定(需结合官方温度范围验证)。

四、封装与可靠性特点

1. 小型化封装优势

0402封装尺寸仅1.0mm×0.5mm×0.5mm,可节省PCB布局空间,适配高密度设计(如智能手机主板、小型物联网模块),是便携设备的理想选择。

2. 焊接与环境适应性

  • 兼容常规回流焊工艺,支持无铅焊接(符合RoHS标准),适配自动化生产;
  • 风华磁珠常规温度范围为**-40℃至+85℃**,满足工业级与消费电子的环境需求(具体需参考官方 datasheet 确认)。

3. 机械可靠性

采用风华成熟的片式元件工艺,结构稳定,抗机械应力能力较强,批量贴装不良率低,适合量产应用。

五、选型优势总结

相比同类0402封装磁珠,CBG100505U301T的核心优势在于:

  1. 频段精准匹配:100MHz频段300Ω阻抗针对性强,滤波效果明确;
  2. 低损耗设计:800mΩ DCR兼顾直流传输效率与交流滤波,适配低功耗设备;
  3. 性价比突出:风华品牌保障可靠性,成本控制良好,适合量产;
  4. 应用灵活:单通道设计适配多种信号/电源线路,布局自由度高。

该产品是低电流、高频干扰抑制场景的高性价比选择,可满足多数消费电子、通信设备的EMI滤波需求。

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.
