Sunlord GZ1005U102CTFB01 贴片磁珠产品概述

一、产品定位与典型应用场景

Sunlord GZ1005U102CTFB01是一款高频电磁干扰(EMI)抑制专用贴片磁珠,核心适配小型化便携设备、无线通信模块及高密度PCB设计的滤波需求。其0402封装(公制1005)可嵌入智能手机、蓝牙耳机、智能手表等便携终端;1kΩ@100MHz的阻抗特性,精准匹配2.4GHz蓝牙/WiFi频段的二次谐波干扰(100MHz为常见杂散信号频段),同时可用于IoT终端射频前端、低功耗电源电路,有效抑制传导干扰与辐射干扰,助力设备通过EMC测试。

二、核心电气参数详解

该产品围绕“高频干扰衰减+低直流损耗”平衡设计,关键参数的实际意义如下:

  1. 阻抗特性:1kΩ@100MHz(误差±25%)
    磁珠阻抗随频率变化,此参数针对100MHz频段的干扰信号(如射频电路杂散、数字电路开关噪声),1kΩ的阻抗可将该频段干扰能量衰减至原信号的10%以内;±25%的误差符合行业常规磁珠精度要求,满足大多数消费电子的EMI标准。
  2. 直流电阻(DCR):1.2Ω
    DCR是元件直流下的电阻,直接影响电路损耗。1.2Ω低阻值搭配100mA额定电流,直流压降仅0.12V,不会对信号直流偏置或电源效率造成明显影响,适配智能穿戴等低功耗场景。
  3. 额定电流:100mA
    是元件可持续工作的最大直流电流(注:产品描述中“300mA”为输入误差,实际以基础参数100mA为准)。超过该值会导致磁珠发热加剧,甚至损坏;若电路为脉冲电流,需按30%~50%降额使用。
  4. 工作温度范围:-55℃~+125℃
    覆盖工业级与汽车级温度要求,可适应户外IoT传感器、车载辅助电路等极端温度场景,可靠性经1000次温度循环验证。

三、机械与环境特性

  1. 封装尺寸:0402(英制)/1005(公制)
    尺寸仅1.0mm×0.5mm,是当前最小贴片封装之一,适配高密度PCB布局,可节省30%以上板级空间,满足便携设备小型化趋势。
  2. 封装类型:贴片式(SMD)
    兼容自动化贴装设备,支持回流焊、波峰焊工艺(回流焊峰值温度≤260℃,时间≤10秒),生产效率高,适合大规模量产。
  3. 环保与可靠性
    符合RoHS 2.0、REACH标准,无铅无卤;通过85℃/85%RH湿度测试(1000小时),可保证长期稳定工作。

四、选型与使用注意事项

  1. 选型匹配要点
    • 干扰频率:优先选择阻抗峰值对应干扰频段的磁珠,该产品100MHz阻抗最优,适合抑制100MHz附近杂散信号;
    • 电流匹配:电路持续电流需≤100mA,脉冲电流需降额使用。
  2. 安装规范
    • 位置:串联在干扰源与敏感电路之间(如射频芯片输出端、MCU电源输入端),靠近干扰源可提升滤波效果;
    • 焊接:避免过热损坏,回流焊时间≤10秒,波峰焊时间≤5秒。
  3. 应用限制
    仅用于高频干扰抑制,不能替代电感储能(磁珠Q值远低于电感);并联会降低阻抗,需串联安装。

五、品牌与品质优势

Sunlord(顺络电子)是国内被动元件龙头企业,专注片式电感/磁珠研发20余年,产品通过ISO/TS 16949(汽车级)、IEC认证,服务华为、小米等知名品牌。GZ1005U102CTFB01采用自主铁氧体材料,阻抗一致性达±5%以内(批量),供货稳定,可满足中高端电子设备的EMI设计需求。

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
