MLZ2012M150WTD25 产品概述

一、产品简介

TDK MLZ2012M150WTD25 是一款车规级叠层贴片电感,标称电感量为 15 µH,公差 ±20%,封装为 0805(2012 套件)。该型号额定电流 250 mA,饱和电流(Isat)为 120 mA,直流电阻(DCR)约 950 mΩ,并通过 AEC‑Q200 车规可靠性认证,适用于对可靠性和温度稳定性有较高要求的电子设备。

二、主要性能与特点

  • 电感值:15 µH,适合较低频率的滤波和去耦应用。
  • 精度:±20%,满足一般电源滤波容差要求。
  • 电流能力:额定电流 250 mA(温升与长期工作参考),饱和电流 120 mA(超过该值电感量显著下降)。
  • 直流电阻:约 950 mΩ,影响功耗与压降,需在功率预算中考虑。
  • 结构:叠层工艺,体积小、寄生电容和自谐振频率适中。
  • 车规等级:符合 AEC‑Q200,适合汽车电子及高可靠性产品。

三、典型应用场景

  • 汽车电子中的低频电源滤波与去耦(例如车载 MCU、传感器供电)。
  • 电池供电便携设备的输入滤波与噪声抑制。
  • DC‑DC 变换器输入/输出滤波(尤其是空间受限场合)。
  • EMI/射频干扰抑制与模拟电路的噪声隔离。

四、选型与使用注意事项

  • 饱和电流(Isat)与额定电流不同:若电感工作时可能出现短脉冲或过载,应以 Isat 为界,避免电感值在工作点大幅下降。
  • DCR 与功耗:950 mΩ 的 DCR 在高电流下会产生可观的 I^2R 损耗与发热,设计时应计算压降和热量。
  • 温度与频率特性:叠层磁性材料在温度和直流偏置下会引起电感漂移,需预留裕量。
  • 封装与空间:0805 封装便于贴片自动化,但焊盘尺寸与 PCB 强度需按厂家推荐设计。

五、PCB 布局与焊接建议

  • 靠近噪声源或供电端放置以缩短回路长度,降低寄生阻抗。
  • 保持焊盘对称,避免应力集中;推荐使用厂商给出的焊盘尺寸和回流焊工艺曲线。
  • 回流焊温度应遵循 TDK 的焊接规范,避免超温或长时间加热导致性能退化。
  • 对于关键散热场合,注意周围铜箔面积分布,避免局部过热影响电感参数。

六、可靠性与认证

  • 通过 AEC‑Q200 说明该器件适用于汽车电子中常见的热循环、机械振动和长期工作可靠性验证。
  • 实际设计中仍应考虑电磁兼容、长期热老化及潮湿环境的封装影响,必要时进行系统级的环境应力测试。

七、采购与替换建议

  • 标准采购通常为带卷包装(tape‑and‑reel),具体卷盘数量与包装方式以供应商说明为准。
  • 替换时关注电感量、Isat、DCR、封装尺寸及 AEC‑Q200 等级的匹配,尽量选用同系列或同厂商同规格产品以保证一致性。

总结:MLZ2012M150WTD25 以其 15 µH 的电感值、车规认证和紧凑 0805 封装,适用于对可靠性和空间有要求的低频滤波与去耦场合。设计时应综合考虑饱和电流、DCR 与热管理,按制造商推荐的 PCB 与焊接工艺安装以保证性能与长期可靠性。若需详细电气特性曲线和回流焊档案,请参考 TDK 官方数据手册。

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
