MLZ1608M100WTD25 产品概述

一、产品简介

MLZ1608M100WTD25 为 TDK 出品的叠层贴片电感(0603/1608公制封装),名义电感值为 10 μH,公差 ±20%。该器件为车规级(符合 AEC‑Q200),适用于空间受限且对可靠性要求较高的电子系统。典型直流电阻(DCR)为 1.05 Ω,额定电流 250 mA,磁饱和电流(Isat)标称为 90 mA(通常定义为在该电流下电感值下降到规定比例时的临界值)。

二、主要特性与优势

  • 体积小(0603 / 1.6 × 0.8 mm),易于在高密度贴片布局中使用。
  • 车规等级 AEC‑Q200,经过汽车级可靠性验证,适合车载及严苛环境应用。
  • 叠层结构提供稳定的电感特性和良好的批次一致性。
  • 10 μH 的较大电感值适合滤波、去耦与低频噪声抑制应用。

三、应用场景

  • 传感器及模拟前端滤波,抑制共模/差模噪声。
  • 低电流电源滤波与 L–C 滤波器网络(适用于电流受限场合)。
  • 汽车电子子系统(车内网络、仪表、低速控制模块)需考虑电流与饱和特性。
  • 通信终端的干扰抑制与信号线滤波(在允许的电流范围内)。

四、关键电气参数解析

  • 电感值:10 μH ±20%(在制造商规定的测试条件下测量)。
  • 额定电流:250 mA —— 通常为在允许温升和可接受电阻损耗下的最大连续电流。
  • 饱和电流(Isat):90 mA —— 当电路中存在直流偏置或较大直流分量时,超过此值电感会明显下降(影响滤波性能),需要优先关注。
  • 直流电阻(DCR):1.05 Ω —— 相对较高,流经大电流时会引起明显的压降与 I^2R 损耗(例如在 250 mA 时约 0.26 V 压降和 ~66 mW 损耗),因此不推荐用于大电流功率路径。

五、封装与可靠性

0603(1608)封装适合自动贴装与回流焊工艺。器件已通过 AEC‑Q200 认证,表明其在温度循环、湿热、机械应力等汽车级可靠性试验中满足要求。设计时仍应考虑焊盘设计、热循环应力与 PCB 应力缓解。

六、选型建议与注意事项

  • 若电路中有直流偏置或持续较大直流电流,需注意 Isat(90 mA)远低于额定电流的情况:若需保持接近标称 10 μH,应确保通过电感的直流分量远低于 Isat。
  • 对于需要传输较大电流或减少压降的场合,建议选用更低 DCR 或更大封装的功率电感。
  • 在滤波设计中,可结合适当容值的电容组成 L‑C 或 π 型滤波器,以达到期望的截止频率和插入损耗。
  • 关注厂商数据表中的测试条件(测量频率、温度等)和环境限制,实际电感值会随频率、温度和偏置电流变化。
  • 进行样片验证时建议测量在实际工作点下的电感与损耗(包括在目标温度和直流偏置下的 L、DCR、温升)。

七、结论

MLZ1608M100WTD25 为一款体积小、车规级的 10 μH 叠层贴片电感,适合汽车及空间受限的低功耗滤波应用。设计时应重点考虑直流偏置导致的电感降额和相对较高的 DCR 带来的压降与功率损耗。若应用要求在较高直流电流下仍保有稳态电感性能,应优先选型更大封装或低 DCR 的电感产品。

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.
