HZ1005U102TFB01 产品概述

一、产品简介

HZ1005U102TFB01 为 Sunlord(顺络)系列磁珠器件,标称在 100MHz 时阻抗 1kΩ,额定电流 250mA,直流电阻(DCR)约 1.1Ω,公差 ±25%。器件常见用于高频干扰抑制与 EMI 滤波,适合空间受限的表面贴装场合。描述中标注 0402 封装(对应 1005 公制尺寸,约 1.0 × 0.5 mm),单通道设计,用于在信号或电源线上串联以增加高频阻抗。

二、主要参数(关键指标)

  • 阻抗:1 kΩ @ 100 MHz(用于评价对射频噪声的抑制能力)
  • 直流电阻(DCR):1.1 Ω,公差 ±25%(影响直流压降与发热)
  • 额定电流:250 mA(最大连续允许电流,超过会产生过热或磁饱和)
  • 通道数:1(单端串联器件)
  • 封装:0402(体积小、适合高密度 PCB 布局)
  • 品牌:Sunlord(顺络)

三、性能与应用场景

HZ1005U102TFB01 在低至中频段电源与信号线上提供高频噪声抑制,典型应用包括:

  • 数字与高速信号线的射频干扰抑制(接口、时钟线)
  • 小电流供电轨的去耦与噪声抑制(便携设备、传感器前端)
  • 模块化电路中对 EMI 辐射的局部控制
    需注意:由于 DCR 较高(约 1.1 Ω),在高电流或对压降敏感的电源轨上可能引起明显电压降和发热,不适合作为大电流滤波元件。

四、封装与安装建议

  • 封装:0402(体积小,焊盘需按厂商推荐尺寸设计)。
  • 布局:尽量靠近噪声源或进入点串联放置,靠近接收端可提供末级滤波;避免直接靠近敏感模拟输入的参考节点。
  • 焊接:建议采用回流焊工艺,严格按照顺络推荐的回流曲线与峰值温度,避免过热导致性能退化或机械损伤。
  • 机械应力:0402 尺寸脆弱,贴装和回流后应避免强烈弯曲或机械冲击。

五、选型与注意事项

  • 电压降评价:在最大额定电流 250 mA 下,直流压降约 V = I × R ≈ 0.25 A × 1.1 Ω ≈ 0.275 V,应评估是否可接受;长期满载将产生发热。
  • 饱和与温升:磁珠并非磁芯电感,长期高流时可能出现温升或性能漂移,应留有安全裕度(建议在长期应用下进行电流降额)。
  • 替代方案:若需更低 DCR 或更大电流能力,可考虑更大封装或专用电感/大电流磁珠产品;若需要差模抑制,考虑共模滤波器。
  • 可靠性验证:关键电路应进行热循环、湿热和电流应力测试以验证长期稳定性。

六、检测与品质确认

  • 阻抗测量:使用阻抗分析仪或 VNA 在目标频率(如 100 MHz)测量阻抗特性曲线以验证 1 kΩ 指标。
  • DCR 测试:采用四线制欧姆表在常温下测量直流电阻并评估与公差范围的一致性。
  • 实机验证:在目标电路中评估 EMI 抑制效果、压降与温升,确保满足电磁兼容与热管理要求。

总结:HZ1005U102TFB01 适用于对高频噪声有较高阻抗需求且电流较小的场合,0402 小型封装利于高密度设计;选型时需重点关注其较高的 DCR 和电流限制,合理布置和降额使用可获得稳定的 EMI 抑制效果。若需详细封装尺寸、温度范围与回流工艺参数,建议参阅顺络正式资料或联系供应商获取完整数据手册。

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
