FAUL0420-6R8MT功率电感产品概述

一、核心参数总览

FAUL0420-6R8MT是长江微电(cjiang)推出的贴片功率电感,核心参数覆盖电感性能、可靠性与应用适配性,具体如下:

  • 电感值:6.8μH(精度±20%);
  • 电流能力:额定电流(温升电流)2.4A,饱和电流(Isat)2.5A;
  • 直流电阻(DCR):175mΩ;
  • 封装规格:0420(贴片尺寸4.2×4.4mm);
  • 可靠性认证:AEC-Q200车规等级;
  • 封装类型:SMD(表面贴装)。

这些参数明确了器件的性能边界,为不同场景的选型提供清晰参考。

二、关键性能指标解析

1. 电感值与精度

6.8μH是功率电感的典型常用值,适配大多数中低功率DC-DC转换电路(如降压/升压拓扑)。±20%的精度属于电感类器件的商业级常规精度,既满足电路对储能的基本要求,又避免了高精度器件的成本冗余,降低BOM设计压力。

2. 电流能力设计

  • 额定电流(2.4A):指电感在额定条件下,自身温升不超过行业标准(通常40℃)的最大持续工作电流,是实际应用的推荐上限;
  • 饱和电流(2.5A):指电感值下降30%时的临界瞬时电流(如电路启动浪涌)。

两者差值仅0.1A,说明磁芯饱和特性优异——电流波动对电感值的影响极小,适合对输出稳定性要求较高的场景(如车载传感器电源)。

3. 低损耗DCR设计

175mΩ的直流电阻属于同类封装的低损耗水平。以额定电流2.4A计算,电感直流损耗为:
( I^2 \times DCR = 2.4^2 \times 0.175 \approx 1W )
低损耗可有效降低电源模块整体功耗,提升设备续航(如便携式电子)或节能效果(如工业控制)。

4. 小型化封装优势

0420封装(4.2×4.4mm)比传统功率电感体积缩小约30%,适配空间受限场景(如手机快充模块、车载中控);SMD封装支持自动化贴装,大幅提升生产效率,降低人工成本。

三、车规级可靠性保障

FAUL0420-6R8MT通过AEC-Q200车规认证,满足汽车电子行业的严苛可靠性要求:

  • 宽温适应性:耐受-40℃至125℃(汽车级典型温区),适应极端天气下的车载环境;
  • 机械稳定性:通过振动(10-2000Hz)、冲击(1000m/s²)测试,可承受汽车行驶中的颠簸震动;
  • 耐久性:经过高温存储、湿热循环等老化测试,确保长期使用性能稳定,故障率低。

这一认证使其成为车载电子电源电路的可靠核心器件。

四、典型应用场景

结合参数与可靠性,FAUL0420-6R8MT适用于多领域:

  1. 车载电子:中控系统电源、仪表盘背光驱动、ADAS传感器(摄像头/雷达)辅助电源、车载无线充;
  2. 消费电子:智能手机/平板快充DC-DC模块、无线耳机充电盒电源、便携式蓝牙音箱供电;
  3. 工业控制:小型PLC电源、电机驱动低压辅助电源、物联网终端供电;
  4. 照明领域:汽车氛围灯、室内智能照明的低功率LED驱动储能电感。

五、品牌与品质背书

长江微电(cjiang)是国内专注电感研发的成熟厂商,拥有10余年功率电感制造经验,产品覆盖消费电子、汽车电子等领域。FAUL0420-6R8MT采用:

  • 优化磁芯材料(低损耗、高饱和);
  • 精密绕线工艺(确保电感值一致性);
  • 严格出厂测试(电感值、DCR、耐压等全检)。

品质稳定可靠,适合批量采购与长期使用。

六、产品总结

FAUL0420-6R8MT是一款平衡小型化、高可靠性与低损耗的贴片功率电感:

  • 车规认证使其在车载场景表现突出;
  • 紧凑封装适配消费电子、工业控制等空间受限场景;
  • 参数设计兼顾性能与成本,是电源设计工程师的实用选型。

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.
