FXL0518-100-M 产品概述

一、产品简介

FXL0518-100-M 是长江微电(cjiang)推出的一体成型功率电感,标称电感值 10 μH,公差 ±20%,面向中小功率开关电源滤波与储能场合。封装为 SMD,外形尺寸约 5.2 × 5.4 mm,适合表面贴装自动化生产,具有良好的机械强度和长期可靠性。

二、主要电气参数

  • 电感值:10 μH(±20%)
  • 额定电流:2.5 A(连续工作建议值)
  • 饱和电流(Isat):3 A(接近或超过时电感量显著下降)
  • 直流电阻(DCR):155 mΩ(典型值)
  • 类型:一体成型功率电感,SMD 封装

说明:DCR 为 155 mΩ 时,在额定电流 2.5 A 下的铜耗约为 P = I^2·R ≈ 0.97 W,需注意器件发热与周边温升。饱和电流 3 A 表示超过该电流时电感无法维持标称储能,电感量会明显下降,应避免长期运行在接近饱和区。

三、产品特性与优势

  • 小型化封装,便于高密度布局与表贴工艺;
  • 一体成型结构,强抗振动、耐焊接热循环;
  • 适用于中等电流等级的升降压转换器、功率滤波器与负载隔离;
  • 较高的饱和电流性能,短时承受峰值电流能力较好。

四、典型应用场景

  • 开关电源(DC-DC)输出滤波与储能电感;
  • LED 驱动电源与电流平滑回路;
  • 电池供电装置的能量滤波与瞬态抑制;
  • 工业控制、通信设备的功率管理模块。

五、设计与使用建议

  • 电流选型:为保证稳定性与寿命,建议对额定电流进行 20%~30% 余量设计,避免长期在 Isat 附近工作;
  • 热管理:由于 DCR 较大,在高电流工况下器件自身耗散接近 1W,应预留散热空间或采用良好散热层、过孔辅助手段;
  • PCB 布局:尽量将电感与 MOSFET/整流器及电容靠近布置,缩短高 di/dt 回路路径,增大铜厚或铜箔面积以降低导通损耗与热阻;
  • 焊接工艺:适配无铅回流工艺参数,按通用 SMD 元件焊接规范控制峰值温度与时间,避免过度加热影响性能;
  • 测试建议:感值测量时注意测试频率与施加的直流偏流,电感在 DC 偏置下会发生降低,应在设计时考虑偏磁特性。

六、选型与替代方案

当系统对铜耗、发热或效率要求较高时,若 155 mΩ 的 DCR 导致功率损耗不可接受,应考虑同等电感值但更低 DCR 或更大体积/更高等级额定电流的型号;若空间更受限且电流较小,可选用更小封装但电流等级相应下降的器件。

七、采购与质量提示

购买时请向供应方索取详细数据手册和电流-感值曲线、温升测试数据,以便在具体工作条件下评估性能。器件为 SMD 类元件,存储和贴装时请遵循防潮与 ESD 管理规范,避免长期潮湿环境存放。

总结:FXL0518-100-M 以其紧凑的 SMD 封装和较高的饱和电流适合中等功率电源滤波与储能应用,但需重视其 DCR 导致的功率损耗与热管理,合理的电流余量与 PCB 散热设计是保证稳定工作的关键。若需更详细的频率响应、温升或电流偏置曲线,请参考厂方数据手册或联系厂商技术支持。

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
