FAUL0420-2R2MT — 5A 功率电感产品概述

一、产品概况

FAUL0420-2R2MT 是长江微电(cjiang)面向车规与工业级电源应用开发的一款 SMD 功率电感。封装为 0420(尺寸约 4.2 × 4.4 mm),具有 2.2 µH±20% 的标称电感值和较低的直流电阻,适用于要求高电流、稳定工作与空间受限的电源场合。该器件符合 AEC‑Q200 车规等级,支持高可靠性和批量量产应用。

二、主要参数

  • 品牌:cjiang(长江微电)
  • 型号:FAUL0420-2R2MT
  • 电感值:2.2 µH,公差 ±20%
  • 额定电流(Irms):4.5 A(连续工作建议电流,要考虑温度与环境)
  • 饱和电流(Isat):5.0 A(在该电流附近电感开始显著下降)
  • 直流电阻(DCR):典型 58 mΩ(在 25°C 条件下测量)
  • 封装:SMD,0420(实际外形约 4.2 × 4.4 mm)
  • 封装形式:片式贴片,适配自动贴装/回流焊接
  • 车规等级:AEC‑Q200

三、主要特性与优势

  • 高电流承载能力:4.5 A 的额定电流和 5 A 的饱和电流使其适用于中高电流的开关稳压器(如降压转换器)和电流滤波场景。
  • 低 DCR:58 mΩ 的低直流电阻有助于降低 I²R 损耗,提高能效,减少温升。
  • 车规认证:AEC‑Q200 认证保证在汽车工作环境下的稳定性与可靠性,适合车载电源、ADAS、通信模块等关键系统。
  • 紧凑封装:4.2 × 4.4 mm 的 SMD 外形兼顾磁性能与 PCB 空间利用率,便于表面贴装自动化生产。
  • 适用温度与环境:设计用于严苛工作环境,具有良好的热稳定性与机械可靠性(详见产品规格书的温度特性与寿命测试)。

四、典型应用

  • 汽车电子:车载 DC‑DC 降压模块、车载充电系统、车身与信息娱乐电源管理。
  • 电源管理:同步降压(buck)稳压器的储能/滤波电感、电流滤波器。
  • 工业与通讯:工业控制电源、通信基站设备、电源模块化设计。
  • 通用消费电子:需要中高电流的电源模块,尤其在空间受限场合替代传统电感。

五、封装、焊接与包装

  • 封装类型:SMD 0420,适配自动贴装;外形紧凑,便于多层 PCB 布局。
  • 焊接建议:建议采用标准无铅回流焊工艺(遵循 JEDEC 回流曲线);注意器件在回流焊过程中的热循环限制,避免超出厂家推荐的峰值温度与时间。
  • 包装方式:通常采用卷带(Tape & Reel)形式,便于 SMT 自动化生产线使用。具体包装数量与规格以报价单或规格书为准。

六、选型与使用建议

  • 留有饱和裕量:在选型时应考虑最大瞬态电流与纹波电流,尽量将工作电流低于 Isat,以避免电感值剧降影响开关稳压器性能。
  • 考虑温升与散热:DCR 的损耗会伴随温度上升而增加,建议评估 PCB 铜箔面积、过孔散热和周边元件布局以控制温度。
  • DC 偏置影响:电感值随直流偏置电流会有下降,应在目标工作点验证实际电感以保证滤波/储能需求满足。
  • 布线建议:输入端与地之间的滤波回路应尽量缩短高频回路面积,输出侧电感与电容靠近稳压芯片布置以减小环路噪声。

七、可靠性与认证

  • 车规等级:通过 AEC‑Q200 测试,满足汽车电子在温度循环、机械振动与湿热等严苛条件下的可靠性要求。
  • 环保合规:符合常见环保要求(如 RoHS);具体合规证明/证书可向供应商索取。

八、订购与资料支持

  • 订购型号:FAUL0420-2R2MT(请在采购时注明工作批次与需求量以便确认交期)
  • 技术资料:建议在设计前索取最新版规格书(包含电感随电流曲线、温升测试、回流焊曲线和推荐 PCB 封装)以及样品进行实机验证。
  • 品牌与服务:长江微电(cjiang)提供技术支持与可靠性测试报告,可配合客户进行应用评估与量产支持。

如需针对目标电源拓扑(例如某款 buck 芯片)进行具体的电感选型验证或索取规格书与样品,我可以协助梳理测试方案与设计注意事项。

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
