FXL0420-R47-M 产品概述

一、产品简介

FXL0420-R47-M 为长江微电(cjiang/长江微电)推出的一款表面贴装一体成型功率电感,额定电流 7.5A,饱和电流(Isat)9.5A,标称电感值 470nH,允许偏差 ±20%。封装为 SMD,外形尺寸约 4.2×4.4mm,适合空间受限但需较大电流承载能力的电源应用场合。

二、主要规格与典型参数

  • 电感值:470 nH ±20%
  • 额定电流(Ir):7.5 A(长期工作推荐值)
  • 饱和电流(Isat):9.5 A(在此电流下电感值显著下降)
  • 直流电阻(DCR):约 14 mΩ
  • 封装:SMD,一体成型,尺寸 4.2 × 4.4 mm
  • 类型:功率电感 / 一体成型电感

三、主要特性

  • 高电流承载:适用于中高电流点负载与降压开关电源(buck)滤波场景。
  • 低直流电阻:14 mΩ 的 DCR 有利于降低导通功耗,但在高电流下仍需关注热量产生。
  • 一体成型结构:机械强度高、抗冲击振动能力强,便于贴片加工与自动化生产。
  • 紧凑封装:4.2×4.4mm 小体积,有助于高密度 PCB 布局。

四、典型应用

  • DC-DC 降压转换器(点负载电感)
  • 电源滤波器与输出滤波阵列
  • 通信设备、电源模块、工业控制、消费类电子的电源管理
    (在特定要求严格的汽车或医疗应用中,请依据系统认证要求核实器件合规性)

五、选型建议与使用注意

  • 工作电流建议不超过额定电流 7.5A,以保证长期稳定与温升可控;短时冲击电流可接近或达到 Isat,但会导致电感降低。
  • 考虑功耗与温升:在 Ir = 7.5A 时,电损 P ≈ I^2·DCR = 7.5^2 × 0.014 ≈ 0.79 W;须设计足够的散热路径(增强 PCB 铜箔面积、良好焊盘和热散布)。
  • 高频性能与纹波电流:根据具体换流频率与纹波电流计算有效电感值与损耗,必要时配合布局优化与磁屏蔽措施。
  • 焊接工艺:支持常规回流焊,但避免长时间波峰或过高回流温度导致材料应力,遵循厂商回流曲线。

六、封装与机械安装

  • SMD 封装利于自动贴装与回流焊接;推荐使用厂家提供的 PCB 焊盘示意图以确保良好电气热性能。
  • 尺寸 4.2×4.4mm,安装时注意边缘间距及周围元件散热影响,避免底层空气隔热过多。

七、可靠性与热管理

  • 长期可靠性依赖于温升控制与电流裕量,建议在设计初期进行热仿真与测温验证。
  • 对于频繁大电流脉冲场景,应评估磁饱和对输出电流波形与系统稳定性的影响,并留足安全裕量。

八、订购与替代方案

  • 型号:FXL0420-R47-M,品牌:cjiang(长江微电)。订购时请核对电感值、公差、额定/饱和电流与 DCR。
  • 如需更低 DCR 或更小尺寸,可与供应商沟通替代型号或定制解决方案;同类规格可参考其它厂商的 470nH/高电流功率电感以比较性能与成本。

如需我为您的具体电源拓扑计算电感值、纹波电流影响或给出 PCB 布局建议,可提供输入/输出电压、开关频率、纹波要求等参数,便于做针对性优化。

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
