MMZ1608Y121BTD25 产品概述

一 产品简介

MMZ1608Y121BTD25 是 TDK 推出的一款 0603(1608 公制)封装的磁珠,用于抑制印制板上的电磁干扰(EMI)和高频噪声。器件在 100 MHz 时标称阻抗为 120 Ω,适合对中低频至中频范围噪声进行衰减与滤波控制。单通道设计、体积小、适配表面贴装工艺,适用于移动设备、通信模块、消费电子和一般工业电子产品的电源与信号线滤波。

二 主要电气参数

  • 阻抗:120 Ω @ 100 MHz(标称)
  • 阻抗容差:±25%(器件间允许的阻抗变化)
  • 直流电阻(DCR):约 200 mΩ
  • 额定直流电流:500 mA(最大连续电流)
  • 通道数:1(单通道)
  • 工作温度:-55 ℃ 至 +125 ℃
  • 封装:0603(1608 公制)

备注:阻抗随频率变化,100 MHz 为参考点,实际设计时应参考完整频率响应曲线;±25% 为阻抗容差,实际阻抗可在约 90–150 Ω 范围内波动。

三 性能特点

  • 高频抑制效果明显:在 100 MHz 附近具有较高阻抗,有效衰减来自电源线与信号线的辐射和传导噪声。
  • 低 DCR:约 200 mΩ 的直流电阻在 500 mA 电流下引起的压降约为 0.1 V,能承受较小的直流负载而对供电影响有限。
  • 小型化封装:0603 尺寸适合高密度布局与自动化贴装。
  • 宽温工作范围:适合多数工业与消费类环境使用。

四 典型应用场景

  • 电源线去耦与输入滤波(DC-DC 输出、LDO 输入/输出)
  • 数字信号线的 EMI 抑制(高速接口附近配合旁路电容)
  • 无线通信模块、移动终端、物联网设备、智能穿戴等对空间有限且对噪声敏感的电路
  • 工业控制与消费电子中一般噪声抑制需求

五 设计与布局建议

  • 贴近噪声源放置:将磁珠放置在噪声源(如电源开关、IC 引脚)与受敏感节点之间,尽量靠近噪声源端焊接,最小化寄生走线。
  • 与旁路电容配合:与地或电源旁路电容共同使用可形成有效滤波网络,磁珠负责中高频衰减,电容负责低频旁路。
  • 短引线与对称焊盘:保持两端走线短且宽,避免引入不必要的寄生电感;采用厂家推荐的焊盘尺寸与回流工艺以确保可靠焊接。
  • 注意电流与压降:在设计中考虑 500 mA 额定电流时的压降与发热,必要时选用并联或更大电流等级器件。

六 可靠性、封装与采购提示

  • 封装为标准 0603 表面贴装,兼容无铅回流焊工艺;详细回流温度曲线与包装形式请参阅 TDK 正式资料与数据手册。
  • 建议在工程设计阶段索取并查阅原厂数据手册,确认完整的频率响应、热特性与机械可靠性测试结果。
  • 订购时请按完整料号(MMZ1608Y121BTD25)核对批次与包装卷盘(Reel)规格,避免混料。

七 使用注意事项

  • 避免超过额定电流与工作温度,以免造成阻抗退化或器件损坏。
  • 对于对噪声衰减有严格要求的系统,应做电磁兼容(EMC)试验并验证实际滤波效果,必要时调整器件型号或并联/串联组合以满足设计目标。

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
