EPZ1005D121-2R0T 产品概述

一、产品简介

EPZ1005D121-2R0T 为顺络(Sunlord)系列高频磁珠(ferrite bead),封装为0402(国际尺寸1005),用于电源与信号线的高频干扰抑制。该器件在 100MHz 时阻抗为 120Ω,适合对中高频段噪声进行吸收与阻尼,常用于便携式设备、通信模块、消费电子等空间受限且对 EMI 有严格要求的场合。

二、主要技术参数

  • 阻抗:120Ω @ 100MHz(典型值)
  • 阻抗误差:±25%
  • 直流电阻 (DCR):50mΩ
  • 额定电流:2A
  • 通道数:单通道(1)
  • 工作温度范围:-55℃ ~ +125℃
  • 品牌:Sunlord(顺络)
  • 封装:0402(1005)

三、产品特性

  • 高频阻抗高:在 100MHz 附近表现出较大的阻抗值,有效抑制高频辐射与传导噪声。
  • 低直流电阻:50mΩ 的 DCR 在保证滤波效果的同时将压降与功耗控制在较低水平,适用于小电流至中等电流的电源线应用。
  • 宽温区可靠性:工作温度覆盖 -55℃ 至 +125℃,可满足工业级温度要求。
  • 小型化封装:0402 尺寸便于在高密度 PCB 上布局,适合移动设备与模块化设计。

四、典型应用场景

  • 手机、平板、可穿戴设备等便携终端的电源线与信号线 EMI 抑制。
  • 无线通信模块(Wi‑Fi、蓝牙、NB‑IoT 等)外围滤波。
  • 电源管理 IC(PMIC)输入/输出端的噪声抑制。
  • 电源轨和敏感模拟前端的干扰隔离。

五、选型与使用注意

  • 电流裕度:额定电流 2A 为器件长期可靠工作的上限,设计时建议留有裕度,考虑峰值电流与长期温升。
  • 频率匹配:磁珠的阻抗随频率变化显著,应结合目标干扰频段(如开关电源噪声或射频带宽)选取合适阻抗曲线。
  • 串联使用:若需更高阻抗或更强抑制,可考虑多颗串联;但需注意总体 DCR 与压降累加。
  • 与旁路电容配合:磁珠常与去耦电容形成 π 型或 T 型滤波网络,以提高低至中高频段的抑制效果。

六、焊接与 PCB 布局建议

  • 布局靠近噪声源(例如电源开关管、LDO 输入端)放置,尽量置于器件与去耦电容之间的路径上。
  • 0402 尺寸对焊盘规格敏感,请参考顺络推荐焊盘尺寸并控制锡膏量,避免虚焊或桥接。
  • 推荐采用回流焊工艺,遵循厂家推荐的回流温度曲线以避免热应力导致基材裂纹。
  • 机械应力规避:在板边或金属插拔孔附近布局时注意避免受力集中。

七、可靠性与测试

  • 常规测试包含阻抗频响测量(在 100MHz 验证 120Ω±25%)、DCR 测量、耐温循环以及回流后电气性能验证。
  • 注意长期高温大电流环境下的自热与电性漂移,必要时做加速寿命测试以评估失效模式。

八、包装与订购信息

  • 封装:0402 卷装供料,适配自动贴片机。
  • 订购时请标注完整料号 EPZ1005D121-2R0T,确认批次与规格要求;如需样品或大量采购可联系顺络或其授权分销商获取技术支持与可靠性报告。

以上为 EPZ1005D121-2R0T 的产品概述与实用建议,如需阻抗曲线、等效电路模型或回流曲线等详细资料,可进一步索取产品规格书(Datasheet)与应用笔记。

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
