顺络SZ1005K750TF片式磁珠产品概述

顺络电子(Sunlord)推出的SZ1005K750TF是一款针对电磁干扰(EMI)抑制设计的片式多层磁珠,采用0402(公制1005)小型封装,凭借精准的阻抗匹配、低直流损耗及宽温适应性,广泛适用于射频通信、电源滤波等场景。

一、产品基本信息与封装特点

SZ1005K750TF属于顺络常规片式磁珠产品线,采用0402封装(公制尺寸1.0mm×0.5mm),体积小巧,可有效节省PCB布局空间,适配便携设备、小型模块的高密度设计需求。产品为单通道无极性结构,焊接安装便捷,符合RoHS无铅环保标准,兼容回流焊、波峰焊等常规贴片工艺。

二、核心电气参数解析

磁珠性能核心围绕高频阻抗、直流损耗及电流承载能力展开,SZ1005K750TF的参数设计平衡了滤波效果与实际应用需求:

  1. 高频阻抗特性:100MHz频率下阻抗为75Ω,误差±25%。该阻抗精准匹配有线电视(CATV)、卫星接收、数字广播等75Ω射频系统,可有效抑制100MHz频段内的电磁干扰,保证信号传输信噪比;±25%公差符合行业通用标准,满足多数工程精度需求。
  2. 直流电阻(DCR):典型值300mΩ,属于低DCR设计。磁珠串联信号/电源回路时,低DCR可减少直流损耗——以额定电流600mA计算,压降仅0.18V,对1V、3.3V等低压电路友好,不影响系统效率。
  3. 额定电流承载:最大工作电流600mA,额定电流范围内磁芯无饱和,阻抗特性稳定,可满足小型电源模块、IoT终端等中低功率电路滤波需求。

三、典型应用场景

SZ1005K750TF的参数特性使其适用于以下场景:

  1. 75Ω射频通信系统:机顶盒、有线电视终端、卫星接收器的射频前端,抑制100MHz左右杂波,提升信号质量;
  2. 小型电源滤波:手机、平板、智能手表等便携设备电源回路,过滤高频噪声,兼顾效率;
  3. 工业级IoT终端:-55℃~+125℃宽温适配户外传感器、工业控制器,避免设备间电磁干扰;
  4. 消费电子EMC整改:路由器、智能音箱等信号线路,满足电磁兼容(EMC)标准,通过认证测试。

四、可靠性与环境适应性

  1. 宽温工作范围:-55℃至+125℃,覆盖工业级(-40℃~+85℃)及部分汽车级场景,高低温交替环境下长期稳定;
  2. 封装可靠性:采用顺络多层陶瓷工艺,抗机械应力(振动、冲击)能力强,耐回流焊峰值温度(260℃),无长期性能衰减;
  3. 抗干扰稳定性:高频阻抗对差模、共模干扰均有抑制作用,100MHz频段滤波效果显著,降低电磁辐射与传导干扰。

五、选型与应用注意事项

  1. 选型匹配:电路阻抗75Ω、干扰集中100MHz、电流≤600mA时优先选择;电流需求更高(如1A+)可考虑顺络SZ1608系列(0603封装);
  2. 安装建议:焊盘与封装尺寸匹配,避免虚焊;靠近干扰源/敏感元件布局,最大化滤波效果;
  3. 电流余量:实际工作电流建议不超额定电流80%(480mA),预留余量提升长期可靠性。

总结:顺络SZ1005K750TF以精准阻抗匹配、低损耗及宽温适应性,成为射频通信、电源滤波等领域常用元件,有效解决多数通用场景的EMI抑制需求。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
