MPXV1D0840L1R0 屏蔽功率电感产品概述

MPXV1D0840L1R0是KEMET(基美)推出的车规级高电流屏蔽功率电感,专为汽车电子及工业电源领域的大电流、低损耗场景设计,核心参数与可靠性满足AEC-Q200认证要求,是车载DC-DC转换器、电池管理系统(BMS)等应用的理想选择。

一、产品核心定位与典型应用场景

该电感聚焦中高频大电流功率电路,解决传统电感在大电流下饱和快、损耗高、EMI干扰大的问题,典型应用包括:

  1. 车载电源:12V/48V DC-DC转换器、车载充电器(OBC)的储能滤波;
  2. 电池管理:BMS高压回路的电流检测与滤波,支持高倍率充放电;
  3. 电机驱动:电动助力转向(EPS)、电子刹车(EBS)的电感储能;
  4. 工业电源:服务器电源、光伏逆变器的辅助电源模块,适配高功率密度需求。

二、关键电气性能参数解析

1. 电感量与精度

标称电感1µH,精度±20%,适配200kHz~2MHz中高频开关电源(Buck/Boost拓扑),电感量偏差小,避免输出电压波动。

2. 电流特性

  • 额定电流(Irms):20.8A:持续工作时DCR温升≤40K(行业常规),确保长期可靠性;
  • 饱和电流(Isat):28A:电感值下降≤10%时的峰值电流,比额定电流高34%,应对电机启动、负载突变等瞬态场景。

3. 低损耗设计

DCR最大4.2mΩ,同规格中低损耗水平,大电流下铜损(P=I²R)显著降低,电源效率提升1%~2%,减少散热需求。

4. 屏蔽EMI优势

磁屏蔽结构大幅降低电磁辐射,避免干扰车载传感器、通信模块,满足ISO 11452等汽车EMC标准。

三、机械与可靠性特性

1. 车规级认证

通过AEC-Q200认证,覆盖汽车级环境测试:

  • 工作温度:-40℃~+125℃(极端车载环境适配);
  • 振动冲击:10g/500Hz振动、100g冲击(符合汽车行驶场景);
  • 湿热耐久:85℃/85%RH测试,确保潮湿环境下性能稳定。

2. 封装特性

非标准SMD封装(0840系列),尺寸紧凑(推测8mm×4mm×3mm),适配高密度PCB布局;引脚兼容回流焊/波峰焊,支持自动化贴装。

四、品牌与品质背书

KEMET作为全球被动元器件龙头,车规产品以高可靠性、一致性著称:

  • 全流程管控:符合IATF 16949汽车质量管理体系;
  • 供应链稳定:全球生产基地满足汽车电子量产需求;
  • 技术支持:提供完整datasheet、仿真模型,助力快速设计。

五、选型与应用注意事项

  1. 电流匹配:持续电流≤20.8A,峰值电流≤28A(超峰值需降额);
  2. 散热设计:PCB预留散热焊盘,大电流场景搭配散热片;
  3. 电感验证:示波器测试纹波电流,确认1µH满足滤波需求;
  4. EMI优化:配合滤波电容、合理布局,满足汽车EMC要求。

综上,MPXV1D0840L1R0凭借高电流能力、低损耗、车规可靠性,成为汽车电子及工业电源的高性价比选择,可有效提升系统效率与稳定性。

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.

Electronic component model and package intelligence review on an ESD-safe inspection bench

Model & package intelligence

Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.

BOM matching and alternative component comparison workstation with protected IC samples

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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.

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
