FXL0420-1R0-M 产品概述

一、产品简介

FXL0420-1R0-M 是长江微电(cjiang)推出的一款面向功率电源的表面贴装一体成型电感。标称电感值为 1 µH,公差 ±20%,额定电流 6 A,饱和电流(Isat)为 7 A,直流电阻(DCR)约 27 mΩ。器件封装为 SMD,外形尺寸 4.2 × 4.4 mm,适用于空间受限且需高电流承载能力的功率转换场合。

二、主要特性

  • 电感值:1 µH(±20%)
  • 额定电流:6 A,饱和电流:7 A(Isat)
  • 直流电阻:27 mΩ(典型)
  • 封装:SMD,尺寸 4.2 × 4.4 mm
  • 类型:一体成型(molded)功率电感,结构紧凑,机械强度好
  • 适合高开关频率下的电源滤波与储能应用

三、典型应用

  • DC-DC 降压/升压稳压器(buck/boost)中的能量存储电感
  • 电源输入输出滤波,降低纹波和电磁干扰
  • 电动终端、通信设备和工业控制中的点位电源
  • 高密度电源模块和移动设备电源管理

四、设计与使用建议

  • 饱和与去磁:工作电流接近 Isat 时电感量会明显下降,常建议在额定电流下留有裕量(如工作电流 ≤ 80% 额定值)以避免磁饱和导致性能退化。
  • 损耗计算:铜损主要由 DCR 决定,近似损耗 P ≈ I_rms^2 × DCR;高纹波电流应以有效值(I_rms)计算损耗并评估温升。
  • 布局与焊接:靠近磁芯位置避免热源叠加,焊盘设计参照厂商推荐尺寸以保证可靠焊接与热扩散。符合回流焊工艺,但应按供应商的最高回流温度曲线进行。
  • 高频特性:在高频开关应用中,注意电感在 DC 偏置下的感值下降与自谐频率(SRF)影响,应结合实际开关频率验证滤波效果。

五、选型与注意事项

  • 若系统纹波电流较大或峰值电流接近 Isat,应优先选择额定电流更高或 DCR 更低的型号以降低损耗和温升。
  • 环境温度、封装散热条件和焊点质量都会影响额定电流能力,实际应用中应进行样机验证。
  • 对 EMI 要求严格的场合,注意与电容、布线共同设计以优化共模/差模抑制效果。

六、结论

FXL0420-1R0-M 提供了 1 µH、6 A 额定电流的紧凑型解决方案,适合对体积与电流容量有双重要求的功率电源设计。合理的电流裕量、良好的 PCB 布局及热管理,是保证长期稳定运行的关键。对于需要在有限空间内实现高效率电源转换的应用,FXL0420-1R0-M 是一种实用且性价比高的选择。

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
