CBW100505U050T 片式磁珠产品概述

CBW100505U050T是风华电子(FH)推出的0402封装高频干扰抑制磁珠,专为小型化电子设备的EMI(电磁干扰)滤波设计,具备低直流损耗、宽温适应、高可靠性等核心优势,广泛覆盖消费电子、通信、汽车电子等多领域应用场景。

一、产品基本信息

  • 品牌型号:风华(FH)CBW100505U050T
  • 封装类型:0402(公制对应1005封装,尺寸为1.0mm×0.5mm×0.5mm)
  • 核心定位:针对100MHz频段干扰优化的片式磁珠,平衡滤波性能与直流传输损耗
  • 产品类型:非屏蔽型铁氧体片式磁珠

二、核心电性能参数

该磁珠的关键电性能参数直接决定其滤波能力与应用边界,具体如下:

  1. 标称阻抗:5Ω ±20% @ 100MHz(磁珠阻抗随频率动态变化,此为典型干扰频段的阻抗值)
  2. 直流电阻(DCR):40mΩ max(低DCR设计,大幅降低直流供电或低频信号的功率损耗)
  3. 额定电流:1.8A(直流电流承载能力,保证工作温度不超过额定值;若需更高电流,可通过并联实现)
  4. 阻抗频率特性:低频段(≤10MHz)阻抗<1Ω,不影响信号/电源正常传输;100MHz频段阻抗达5Ω,有效抑制高频噪声;高频段(>1GHz)阻抗进一步提升,覆盖宽干扰频段。

三、封装与物理特性

0402封装的小型化设计适配现代电子设备的轻薄化需求,物理特性符合行业标准:

  • 尺寸规格:长1.0±0.2mm、宽0.5±0.2mm、高0.5±0.2mm(符合IPC-J-STD-001标准)
  • 引脚工艺:两端电极采用镀锡/镀银复合工艺,焊接兼容性强(支持回流焊、波峰焊)
  • 磁芯材料:高性能锰锌铁氧体,保证高频损耗与宽温稳定性
  • 外壳防护:耐高温树脂封装,防护磁芯并提升焊接可靠性(避免高温开裂)

四、典型应用场景

CBW100505U050T的特性使其适用于多领域的EMI滤波需求:

  1. 消费电子:智能手机、平板电脑、智能手表的电源线路滤波(抑制充电噪声)、射频信号线滤波(减少蓝牙/WiFi杂波干扰)
  2. 通信设备:5G基站、路由器、无线模块的射频前端滤波(抑制杂波发射)、电源模块滤波(提升供电稳定性)
  3. 汽车电子:车载导航、ADAS传感器、车机系统的低噪声电路滤波(宽温-55℃~125℃符合汽车级AEC-Q200要求)
  4. 工业控制:PLC、伺服电机驱动器、传感器模块的抗干扰设计(避免工业环境电磁干扰)
  5. 医疗设备:便携式监护仪、血糖仪的信号净化(保证生理信号采集准确)

五、环境适应性与可靠性

该磁珠具备优异的环境适应能力,满足严苛工况需求:

  • 工作温度:-55℃至+125℃(覆盖工业、汽车、航空航天等恶劣环境)
  • 存储温度:-40℃至+85℃(长期存储无性能衰减)
  • 焊接可靠性:回流焊峰值温度260℃(时间≤10s),波峰焊温度250℃(时间≤5s),无电极脱落、磁芯开裂风险
  • 寿命测试:在额定条件下(125℃、1.8A),工作寿命可达10万小时以上

六、选型与使用注意事项

为保证滤波效果与可靠性,需注意以下要点:

  1. 频率匹配:本产品针对100MHz左右干扰优化,若目标干扰频率偏离,需核对风华官方datasheet的阻抗曲线
  2. 电流限制:实际工作电流需≤1.8A,避免过热导致阻抗下降(并联2个可将额定电流提升至3.6A)
  3. 布局建议:磁珠应靠近干扰源(如电源输出端)或敏感电路(如射频前端),减少干扰耦合路径
  4. 焊接工艺:严格遵循风华推荐参数,避免虚焊(可通过X-Ray检测电极焊接覆盖率)
  5. 串联/并联规则:串联可提升阻抗(2个串联阻抗约10Ω@100MHz),并联可提升电流,需注意阻抗/电流的线性关系

总结

CBW100505U050T是一款性能均衡的0402封装磁珠,以低DCR、宽温适应、高可靠性为核心优势,解决了小型化设备的高频干扰痛点,是消费电子、通信、汽车电子等领域的理想EMI滤波器件。

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.
