Sunlord GZ2012D471TF 片式磁珠产品概述

一、产品定位与命名解析

Sunlord GZ2012D471TF是顺络电子推出的高频EMI滤波片式磁珠,核心用于抑制100MHz频段的电磁干扰(EMI),属于工业级宽温适配的小型化无源器件。

命名规则拆解:

  • GZ:顺络磁珠系列通用标识;
  • 2012:公制封装尺寸(对应英制0805),即封装规格为2.0mm×1.2mm;
  • D:系列细分标识(代表特定工艺/性能梯度);
  • 471:阻抗值编码(47×10¹=470Ω),对应频率为100MHz;
  • TF:子系列标识(适配高频滤波场景)。

二、核心电气性能参数

该磁珠的电气性能聚焦100MHz高频干扰抑制,关键参数如下:

  1. 阻抗特性:
    额定阻抗470Ω±25% @100MHz,此规格针对电子设备中常见的100MHz频段杂波(如射频电路杂散、开关电源噪声)设计,阻抗精度满足工业级滤波需求。

  2. 通道数:
    单通道设计,需串联于信号/电源线路中(并联无滤波效果),适配单条线路的噪声抑制。

  3. 温度适应性:
    工作温度范围-55℃+125℃,覆盖工业环境(-40℃+85℃)及部分汽车级场景(-55℃~+125℃),极端温度下电气性能无显著漂移。

补充:磁珠通过“高频阻抗→热能转化”原理工作,不影响直流/低频信号传输,仅衰减目标频段的电磁噪声。

三、封装与工艺特点

  1. 小型化片式封装:
    0805(英制)/2012(公制)封装,尺寸紧凑(约2.0mm×1.2mm×0.8mm),适合高密度PCB布局(如智能手机、路由器等小型设备),节省空间。

  2. 表面贴装兼容:
    采用SMT工艺设计,可通过自动贴片机高效安装,兼容回流焊/波峰焊流程,生产效率高。

  3. 稳定结构设计:
    陶瓷基片+铁氧体磁性材料复合结构,抗振动、抗冲击性能优异(符合IEC 60068-2-6振动测试标准),长期使用无性能衰减。

四、典型应用场景

该磁珠的宽温特性与高频阻抗适配多领域EMI滤波需求:

  1. 通信设备:
    路由器、基站射频模块、光纤收发器等,抑制100MHz附近的杂散信号,提升信号传输质量。

  2. 消费电子:
    智能手机、智能穿戴设备的射频前端(RF)、蓝牙/WiFi模块,减少电磁干扰对无线通信的影响。

  3. 工业控制:
    PLC控制器、传感器节点、工业物联网网关,适配-55℃~+125℃的极端工业环境,防护电磁干扰导致的误触发。

  4. 汽车电子:
    车载信息娱乐系统、ADAS传感器(如毫米波雷达),满足车载级温度要求,保障系统EMC合规性。

  5. 电源电路:
    DC-DC转换器输出端、LED驱动电源,衰减开关电源产生的100MHz高频噪声。

五、环境适应性与可靠性

  1. 宽温稳定性:
    -55℃~+125℃范围内,阻抗变化率≤10%(典型值),无性能突变,适合高低温交替的恶劣环境。

  2. 可靠性认证:
    符合RoHS、REACH环保指令,无铅无卤;通过顺络内部可靠性测试(如湿热老化、盐雾测试),平均无故障时间(MTBF)≥10^6小时。

  3. 一致性保障:
    顺络自动化生产工艺确保批量产品阻抗一致性(±25%误差范围内离散度小),降低系统设计风险。

六、使用注意事项

  1. 安装方式:
    必须串联于待滤波线路(信号/电源),避免并联;需确认线路电流不超过磁珠额定电流(参考 datasheet:该型号额定电流约100mA@25℃),防止磁珠饱和(饱和后阻抗急剧下降,失去滤波效果)。

  2. PCB布局:
    尽量靠近干扰源(如开关电源、射频芯片)或受保护电路,缩短走线长度(≤5mm),减少二次耦合干扰。

  3. 选型替换:
    若需更高阻抗(如1kΩ@100MHz),可选择同系列GZ2012D102TF;若需更低频率滤波,可参考同封装的低频磁珠型号。

该产品凭借宽温特性、高频阻抗精度及小型化封装,成为工业、通信、汽车电子等领域EMI滤波的高性价比选择。

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.
