HZ1005K102TFB01 顺络片式磁珠产品概述

HZ1005K102TFB01是国内电磁干扰(EMI)抑制领域龙头企业顺络电子(Sunlord)推出的0402封装高频片式磁珠,针对100MHz频段的电磁噪声抑制设计,兼具小型化、低损耗与可靠滤波性能,广泛适配便携式电子、IoT模块等高密度PCB场景。

一、产品核心定位与身份

作为顺络经典磁珠系列的一员,HZ1005K102TFB01聚焦100MHz频段的共模/差模干扰衰减,属于单通道片式磁珠,核心价值在于:在极小封装内实现对射频干扰的高效抑制,同时控制直流损耗与发热,满足现代电子设备“小型化+低功耗+抗干扰”的三重需求。

二、关键电气性能参数详解

磁珠的性能核心围绕“频率-阻抗特性”“直流损耗”“电流承载能力”三大维度,HZ1005K102TFB01的参数针对性强:

1. 阻抗特性(核心滤波指标)

阻抗为1kΩ±25%@100MHz:

  • 100MHz是消费电子、无线通信中常见的射频干扰频段(如WiFi 2.4G旁瓣、蓝牙二次谐波等),1kΩ阻抗可将该频段干扰衰减约20dB以上(工程经验值),有效降低信号误码率或电路噪声;
  • ±25%误差为行业常规精度,满足中低端电子设备滤波需求,若需高精度可选择顺络同系列高精度型号。

2. 直流电阻(DCR)与损耗

直流电阻为1.25Ω:
DCR直接影响线路直流压降与功耗,在250mA额定电流下,磁珠直流功耗仅为:
[ P = I^2 \times R = (0.25A)^2 \times 1.25Ω = 0.078W ]
发热可控,不额外消耗便携式设备电量,也避免过热导致的阻抗漂移。

3. 额定电流(安全工作边界)

额定电流为250mA(Irms):
这是持续工作的最大电流上限,超流会导致铁氧体磁饱和或过热,阻抗下降甚至损坏。设计需预留10%-20%电流余量,避免长期过载。

4. 单通道设计

仅支持1通道滤波,适合单路信号(射频天线、传感器输出)或单路电源(5V/3.3V支路)独立干扰抑制,不占用多通道额外空间。

三、封装与物理特性

HZ1005K102TFB01采用0402封装(公制1005,尺寸1.0mm×0.5mm×0.5mm典型值):

  • 适配高密度PCB设计,如智能手机主板、可穿戴设备(手环/耳机)、IoT传感器模块;
  • 顺络采用成熟叠层铁氧体工艺,一致性与可靠性突出,符合RoHS、REACH环保标准,兼容无铅焊接;
  • 工作温度范围**-40℃~+85℃**,满足工业级与消费级设备环境需求。

四、典型应用场景与价值

HZ1005K102TFB01性能匹配以下场景:

1. 消费电子终端

  • 智能手机/平板:射频前端(WiFi、蓝牙、GPS)信号滤波,抑制天线干扰;充电电路电源滤波,减少快充噪声;
  • 可穿戴设备:智能手环心率传感器、无线耳机音频信号线路滤波,兼顾小空间与抗干扰。

2. IoT与通信模块

  • 工业IoT传感器:温度、压力传感器电源/信号线路滤波,避免工厂高频噪声干扰数据传输;
  • 蓝牙/WiFi模块:内部射频匹配网络滤波,提升通信稳定性。

3. 小型电子设备

  • 智能手表:低功耗电路滤波;
  • 便携医疗设备:血糖监测仪信号线路滤波,确保数据准确。

五、选型与使用注意事项

  1. 选型匹配:
    若干扰频段偏离100MHz(如10MHz/1GHz),选顺络同系列HZ1005KxxxTFB01(xxx为阻抗代码,如101对应100Ω@100MHz);超250mA电流需升级至更高额定电流型号(如HZ1005K102TFC01,500mA)。

  2. PCB设计要点:

    • 磁珠靠近干扰源(射频芯片)或敏感器件(传感器)放置,避免长走线引入额外干扰;
    • 0402封装焊盘符合IPC标准,焊接避免虚焊(可通过X-Ray检测)。
  3. 环境注意:
    避免>85℃高温或高湿环境长期工作,否则加速铁氧体老化,导致阻抗下降。

综上,HZ1005K102TFB01是高性价比0402封装高频磁珠,顺络品牌背书与成熟工艺确保可靠性,适合空间敏感、需抑制100MHz频段干扰的电子设备,是便携式产品与IoT模块的常用滤波方案。

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.
