GZ1608D221TF 产品概述

一、产品概述

GZ1608D221TF 是顺络(Sunlord)品牌的一款0603封装磁珠元件,主要用于电源与信号线的电磁干扰(EMI)抑制与去耦。该器件在100MHz时阻抗为220Ω,阻抗误差±25%,直流电阻(DCR)为300mΩ,额定通过电流为300mA,工作温度范围为-55℃至+125℃,为单通道(单线)器件,适合表面贴装工艺。

二、主要参数(关键指标)

  • 阻抗:220Ω @ 100MHz(±25%)
  • 直流电阻(DCR):0.30Ω(300mΩ)
  • 额定电流:300mA
  • 封装:0603(1608公制)
  • 通道数:1
  • 工作温度:-55℃ ~ +125℃

计算参考:在额定电流下,电压压降 ≈ I×R = 0.3A×0.3Ω = 0.09V(90mV);功耗 ≈ I²R = 0.3²×0.3 = 0.027W(27mW),在实际设计中应考虑这些损耗及热升。

三、典型应用

  • 电源输入/输出线的EMI抑制与去耦,尤其是中低频至高频噪声(以100MHz为参考点)。
  • 便携式设备、通信模块、IoT终端的供电滤波与噪声隔离。
  • USB、电池管理与射频前端电路中的干扰抑制(注意对高速差分信号的影响需评估)。
  • 数字电路的局部噪声隔离与地电位分离。

四、设计与布局建议

  • 靠近噪声源或受干扰的负载端放置,常见做法是在IC电源引脚与去耦电容之间布置,以形成有效的滤波网络。
  • 对于高频敏感信号(高速差分对、射频传输线),应评估磁珠带来的串联阻抗对信号完整性的影响,必要时选择更低阻抗或专用滤波器。
  • 注意DCR带来的压降,在电流接近额定值时可能影响供电电压,关键电源轨建议预留裕量或选择更高额定电流的器件。
  • 建议遵循厂商的PCB开窗/阻焊和回流焊工艺建议;如无具体数据,请按常规0603贴片元件的回流温度曲线处理,并避免二次返修多次加热。

五、可靠性与注意事项

  • 使用环境温度不可超过-55℃~+125℃范围,长期超温会影响磁性材料特性与阻抗稳定性。
  • 阻抗标注为100MHz参考值,实际应用中不同频率下阻抗特性会变化,设计时应结合系统频谱选择合适型号。
  • 存储与搬运时注意防潮、防震;在焊接前遵循来料的抗湿包装及干燥要求。

六、选型建议与替代

  • 若系统电流高于300mA,或对压降敏感,应选择额定电流更高、DCR更低的磁珠型号或改用共模/差模滤波器。
  • 若需要更严格的阻抗公差或在不同频段有明确滤波需求,可参考同阻抗带宽更宽或多频点标注的磁珠产品。
  • 购买或替代时,以“阻抗@100MHz=220Ω、DCR≤300mΩ、额定电流≥300mA、封装0603”为主要筛选条件,并优先参考顺络官方datasheet以获得完整的频率特性与热机理说明。

总结:GZ1608D221TF 为一款适用于一般电源与EMI抑制场景的0603磁珠,提供在100MHz处较高的阻抗值,适合对中高频噪声抑制有要求且电流在300mA以内的便携与消费类电子设计。请在最终设计中结合实际频谱、压降和热预算进行验证。

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.
