HZ1005K182TFB03 产品概述

一、产品简介

HZ1005K182TFB03 是顺络(Sunlord)的一款表面贴装磁珠(ferrite bead),规格为 0402(公制 1005)。该器件在 100MHz 时的阻抗为 1.8kΩ,公差 ±25%;直流电阻(DCR)为 2.2Ω;额定电流为 200mA;通道数为单通道(1)。该型号适用于对高频噪声有较强抑制需求且空间受限的移动设备、射频前端及电源滤波场合。

二、关键电气参数与物理特性

  • 阻抗:1.8kΩ @ 100MHz(±25%)——在高频区有显著衰减效果,对射频干扰抑制能力强。
  • 直流电阻(DCR):2.2Ω——相对较高,使用时需关注直流压降及功耗。
  • 额定电流:200mA——超过该电流可能导致温升或参数退化,应按实际工作电流留有余量。
  • 封装/尺寸:0402(1005),适合高密度设计,占用板面小。
  • 通道数:1(单线磁珠),适用于单电源或单信号线的滤波。

三、应用场景与选型建议

  • 典型应用:移动终端电源滤波、射频模块输入/输出、基带与射频之间的噪声隔离、USB/数据线高频干扰抑制等。
  • 选型要点:若线路直流电流接近或超过 200mA,应优先选择额定电流更高、DCR 更低的型号;若对低频噪声也有要求,可与旁路电容配合构建低通滤波网络。注意 0402 尺寸限制了热耗散能力与电流承载,适用于小电流场合。

四、PCB 布局与焊接注意事项

  • 布局:磁珠应尽量靠近噪声源或电路入口处放置,实现源端抑制;对电源线,建议在电源入口与负载之间串联使用。
  • 焊盘与镀层:遵循顺络提供的推荐焊盘尺寸,若无资料,可参考常规 0402 焊盘(焊盘长度约 0.5–0.7mm,间距尽量小以保证焊接可靠性)。
  • 回流焊:可采用无铅回流工艺,遵守器件耐温限制与回流曲线,避免长时间过高温度以免影响特性。

五、可靠性与测试验证

  • 测试方法:阻抗在 100MHz 时可用阻抗分析仪或网络分析仪测量;DCR 可用四线法或高精度万用表测量。
  • 可靠性关注:高 DCR 意味着通过时可能有显著功耗与发热,长期工作在额定电流附近可能导致参数漂移或失效,建议在设计时留足裕量并进行热仿真/实测。
  • 环境适应:常规电子级储存与处理,避免潮湿与机械应力;在高温高湿环境下应关注长期阻抗变化。

六、替代与配套建议

  • 若需更大电流或更低 DCR,可选用更大封装(0603、0805)或同厂其他低阻型磁珠。
  • 在需要形成更好低频抑制时,可与陶瓷旁路电容并联,构成有源/被动滤波组合,实现宽频带抑制。

总结:HZ1005K182TFB03 以其在 100MHz 附近的高阻抗特性,适合用于高频干扰抑制与射频隔离,但 2.2Ω 的 DCR 与 200mA 的限流特性决定了它更适合小电流、对高频噪声抑制有严格要求的应用场景。最终选型与布板应结合实际电流、热设计与系统频谱特性,参照顺络官方资料核对详细焊盘与热参数。

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.
