FAUL0518-2R2MT 功率电感产品概述

一、产品基本定位与核心身份

FAUL0518-2R2MT是长江微电(cjiang)推出的车规级SMD功率电感,专为需要大电流承载、高可靠性的电源电路设计。作为功率电感家族的一员,其核心定位是满足汽车电子、工业电源等场景对“小尺寸、低损耗、高电流”的综合需求,同时通过AEC-Q200车规认证,确保在严苛环境下的稳定工作。

二、关键电气性能参数详解

该电感的核心电气参数直接决定应用边界,需重点关注以下维度:

  1. 电感值与精度:标称电感值为2.2μH,精度±20%。此范围适配中等功率的DC-DC转换、滤波场景,±20%的精度可覆盖大多数功率电路的设计余量,无需额外高精度匹配。
  2. 电流承载能力:
    • 额定电流(Irms):5A(有效值)。指连续工作时,因直流电阻(DCR)产生的温升不超规格的最大电流,是日常应用的安全上限;
    • 饱和电流(Isat):6A。指电感值下降30%时的峰值电流(磁芯饱和临界点),仅作为过流参考极限(不建议长期工作在此电流下)。
  3. 直流电阻(DCR):35mΩ(典型值)。低DCR是核心优势——大电流工作时,功率损耗(P=I²·R)显著降低,减少发热并提升电源效率,适合车载、工业等效率敏感场景。

三、物理封装与工艺特点

  1. 封装尺寸:采用SMD贴片封装,具体为5.4mm×5.2mm×1.6mm(长×宽×高)。紧凑尺寸可节省PCB空间,适配小型化车载模块、工业电源等产品。
  2. 工艺特性:
    • 磁芯与绕组:采用高性能铁氧体磁芯(主流功率电感设计),配合低电阻漆包线,兼顾电感稳定性与低DCR;
    • 贴片可靠性:封装适配自动化贴装,焊接兼容性符合IPC标准;
    • 耐温性:结合车规认证,材料可承受-40℃~125℃宽温范围,满足汽车环境温度波动。

四、车规级可靠性认证

FAUL0518-2R2MT通过AEC-Q200认证(汽车电子核心可靠性标准),涵盖以下关键测试:

  • 温度循环:-40℃~125℃循环,验证极端温度下的性能稳定性;
  • 湿度与温度结合(HAST):模拟高湿高温环境,检测封装密封性;
  • 振动与冲击:符合汽车行驶中的振动(路面颠簸)、冲击(碰撞)要求;
  • 耐久性:长期工作后的性能衰减测试,确保车载生命周期可靠性。

五、典型应用场景

基于电气性能与车规特性,核心应用包括:

  1. 车载电子:车载DC-DC转换器、OBC(车载充电器)辅助电源、ADAS传感器电源;
  2. 工业电源:小型开关电源(100W以内)、LED驱动电源(大电流输出);
  3. 消费电子:65W以上快充充电器、移动电源升压/降压模块;
  4. 通信设备:路由器、交换机的电源滤波电路。

六、选型与应用注意事项

  1. 电流匹配:连续电流≤5A(额定),峰值电流≤6A(饱和),避免长期过流导致磁芯饱和或发热超标;
  2. 精度适配:±20%精度适合功率电路,若需更高精度(如≤10%)需谨慎选型;
  3. 焊接工艺:回流焊遵循长江微电温度曲线(峰值245℃±5℃,时间≤30s),避免手工焊温度过高;
  4. 环境温度:工作温度控制在-40℃~125℃(车规标准),超出可能导致性能下降;
  5. PCB布局:靠近电源输出端或DC-DC芯片电感脚,减少走线长度以降低寄生电感。

总结

FAUL0518-2R2MT凭借“小尺寸、低DCR、高电流、车规可靠性”的综合优势,成为车载电子、工业电源等领域的高性价比选择,可有效满足效率与可靠性双重需求。

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
