顺络SZ1005K102CTF片式铁氧体磁珠产品概述

一、产品基本信息

顺络(Sunlord)SZ1005K102CTF是一款针对高频电磁干扰(EMI)抑制设计的片式铁氧体磁珠,属于顺络成熟的片式磁珠系列产品。该元件采用小型化封装,核心功能是在特定频率范围内衰减干扰信号,同时保持直流信号的低损耗传输,广泛适配消费电子、通信、汽车电子等领域的电路设计需求。

二、关键性能参数详解

1. 阻抗特性(核心EMI抑制指标)

该磁珠的交流阻抗为1kΩ@100MHz,误差范围±25%。阻抗是磁珠抑制高频干扰的核心参数——在100MHz频率下,磁珠表现出较高的交流阻抗,可有效衰减该频段及附近的电磁干扰信号(如射频干扰、开关电源噪声);±25%的误差范围满足大多数电子设备的EMI抑制精度要求,无需额外的精准匹配设计。

2. 直流电阻(DCR)

直流电阻为1.2Ω,该参数直接影响磁珠的直流功耗和信号直流损失。1.2Ω属于低DCR设计,可显著降低磁珠在直流电路中的功率损耗(尤其适用于低功耗设备),同时减少对直流信号(如电源电压、低速数字信号)的压降影响,平衡了EMI抑制与信号完整性需求。

3. 额定电流

额定电流为200mA,指磁珠在工作温度范围内可长期稳定工作的最大直流电流。若电流超过该值,磁珠会因磁饱和或过热导致阻抗下降、性能失效,甚至损坏。200mA的额定电流满足大多数小型电子设备的电流需求(如智能手机单条数据线、可穿戴设备传感器线路)。

4. 环境适应性参数

  • 通道数:1(单通道设计),适用于单条信号线路或电源线的独立干扰抑制;
  • 工作温度:-55℃~+125℃,覆盖宽温环境,适配汽车电子、工业控制等极端温度场景,同时确保消费电子在日常使用中的性能稳定性。

三、封装与尺寸说明

根据顺络磁珠型号命名规则,“1005”对应公制1.0mm×0.5mm封装(英制0402封装),该封装体积小(仅约0.5mm²),适合高密度表面贴装(SMT)工艺,可有效节省PCB空间,适配智能手机、蓝牙耳机、智能手环等便携设备的紧凑布局,同时支持自动化批量生产,降低组装成本。

四、典型应用场景

SZ1005K102CTF的参数特性使其适配多种高频干扰抑制场景:

  1. 消费电子:智能手机、平板电脑、蓝牙耳机的音频线、数据线、电源模块,抑制电磁干扰导致的音频杂音、数据传输误码;
  2. 通信设备:路由器、交换机、基站的射频线路、电源滤波电路,提升信号抗干扰能力;
  3. 汽车电子:车载导航、行车记录仪、传感器(摄像头、雷达)的电路,抑制汽车内部点火干扰、电子设备互扰,满足宽温要求;
  4. 工业控制:工业传感器、PLC模块的信号线路,衰减电机、变频器产生的电磁干扰,确保数据可靠性。

五、产品核心优势

  1. 小型化与高密度适配:0402封装体积小,支持PCB高密度布局,适配便携设备小型化趋势;
  2. 宽温稳定性能:-55℃~+125℃全温范围性能稳定,阻抗与DCR变化小,满足极端环境需求;
  3. 低损耗平衡设计:1.2Ω低DCR减少直流损耗,1kΩ@100MHz阻抗满足高频干扰抑制,平衡信号完整性与EMI控制;
  4. 高可靠性:顺络成熟工艺保障产品一致性,符合RoHS环保标准,适合批量生产应用。

该产品凭借平衡的性能参数与小型化设计,成为各类电子设备EMI抑制方案中的高性价比选择,尤其适配对体积、功耗敏感的便携及汽车电子场景。

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
