MLZ2012M470WTD25 产品概述
MLZ2012M470WTD25 是 TDK 推出的 0805 封装叠层贴片电感，标称电感值 47 µH（公差 ±20%），面向对尺寸、车规可靠性有要求的汽车与工业电子应用。该器件通过 AEC‑Q200 车规认证，适合在严格的温度与振动环境中长期工作。
一、主要特性
- 电感值：47 µH，公差 ±20%
- 饱和电流（Isat）：50 mA（用户提供数据）
- 直流电阻（DCR）：约 3.7 Ω
- 额定电流：170 mA（用户提供数据）
- 封装：0805（2012 公制）表面贴装，叠层结构
- 车规等级：AEC‑Q200 认证
- 品牌：TDK
二、性能亮点与应用场景
- 小体积（0805）且通过车规认证，便于在空间受限的汽车仪表、车载控制单元（ECU）和传感器接口中使用。
- 高电感值适用于低频滤波、信号去耦、模拟电路阻抗匹配与工艺线 EMI 抑制。
- 叠层结构保证了小型化的同时具备良好的一致性和批量可重复性。
三、电气与热性能要点（设计须知）
- DCR 较高（约 3.7 Ω），在较大直流电流下会产生明显的 I^2·R 损耗。举例：在 170 mA 时，功耗约为 0.17^2×3.7 ≈ 0.107 W；在 50 mA 时功耗约 9 mW。需在热设计中考虑功耗与周边温升。
- 饱和电流与额定电流数据存在不一致（Isat=50 mA < 额定电流170 mA）。通常饱和电流应不小于工作电流，否则在较大电流下电感量会显著下降，影响滤波效果。请在最终设计前务必以 TDK 官方数据表为准并与供应商确认测试条件（例如 Isat 的定义：L 降低多少 % 时测得）。
- 温度与频率特性：叠层电感的电感值会随直流偏置、温度与频率变化，应在目标工作点测量或参考厂家频率响应曲线。
四、装配与使用建议
- 推荐按 0805 标准 PCB 焊盘布局进行设计，留意焊膏量与回流曲线，避免热应力造成裂纹。
- 回流焊温度与时间应遵循 TDK 的焊接规范，车规件对焊接工艺敏感度高，建议先做样板试验。
- 在存在大电流脉冲或需要低 DCR 的电源路径中，不建议使用该型号；可用作信号线滤波、传感器接口去耦等低电流场合。
五、选型与注意事项
- 在选择时，请重点核对 Isat、额定电流与 DCR 的定义与测量条件，避免因规格理解不一致导致性能不满足。
- 若目标应用有持续较大直流偏置或需更小损耗，应考虑更低 DCR、或更高截流电流（Isat）的型号。
- 如用于汽车电子，请同时关注温度等级、热循环与机械振动可靠性试验结果。
备注：以上基于您提供的参数整理。由于所给出的饱和电流与额定电流存在逻辑矛盾，建议下载并核对 TDK 官方数据表（datasheet）或咨询供应商，确保器件满足实际工作条件与可靠性要求。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
