FC-SE2918-220M 扁平线功率电感产品概述

FC-SE2918-220M是方成(FC)品牌推出的一款SMD封装高性能功率电感,专为大电流、高效率电力电子场景设计,兼具低损耗、小体积、宽温可靠性等特点,适用于车载电子、工业电源、服务器及LED驱动等领域。

一、产品核心参数概览

FC-SE2918-220M的关键参数明确了其应用边界与性能优势,核心指标如下:

  • 电感值:22μH,精度±20%,满足常规功率电路对电感量的需求;
  • 电流特性:额定电流(Irms)30A(指电感温升≤40K时的持续工作电流),饱和电流(Isat)15A(指电感值下降30%时的临界电流),需注意实际工作电流需低于饱和电流以避免性能衰减;
  • 直流电阻(DCR):2.6mΩ(典型值),低电阻设计大幅降低导通损耗,提升电路效率;
  • 封装与类型:SMD表面贴装封装,适配自动化贴装工艺;采用扁平线绕制,区别于传统圆形导线,优化了高频特性与电流承载能力;
  • 品牌定位:方成(FC)旗下中高端功率电感,面向对效率与可靠性要求较高的场景。

二、设计特点与工艺优势

FC-SE2918-220M依托扁平线结构优势与方成工艺积累,具备以下核心特点:

  1. 低损耗与高电流承载:扁平铜导线相比同截面积圆形导线,表面积更大,高频趋肤效应损耗更低;绕制紧密使电感值一致性好,DCR稳定在2.6mΩ,持续承载30A电流时温升可控;
  2. 紧凑封装适配高密度设计:SMD封装无需额外引线,节省PCB空间,支持自动化回流焊,提升生产效率;
  3. 宽温可靠性:采用耐高温磁芯与绝缘材料,工作温度覆盖-40℃~125℃(行业常规参数),满足车载、工业等极端环境需求;
  4. 抗干扰与一致性:扁平线绕制减少导线间寄生电容,高频抗干扰能力优于传统电感,批量生产一致性高,降低电路调试难度。

三、典型应用场景

FC-SE2918-220M的性能匹配多种大电流功率电路,典型应用包括:

  1. 车载电子:车载快充充电器(QC/PD协议)、车载电机驱动(电动座椅、车窗)、车载DC-DC转换器等,需高电流、小体积与宽温特性;
  2. 工业电源:工业变频器DC-Link电感、光伏逆变器滤波电感、工业开关电源等,需稳定电感值与耐温性;
  3. 服务器与通信:服务器多路DC-DC模块、5G基站电源滤波电感,需低损耗提升整机效率;
  4. LED驱动:大功率LED路灯、显示屏驱动电源输出滤波,需稳定电流输出与低损耗。

四、选型与使用注意事项

为确保性能稳定,需注意以下事项:

  1. 电流选型:实际工作电流≤额定电流的80%(约24A),绝对不超饱和电流15A,避免电感饱和导致电感值骤降;
  2. 焊盘设计:确认PCB焊盘尺寸与电感封装匹配(常规29×18mm级),避免贴装偏移;
  3. 焊接工艺:遵循回流焊曲线(峰值≤245℃,时间≤10秒),禁止手工焊接过热(>260℃可能损坏磁芯);
  4. 环境防护:避免高湿度(>85%RH)、腐蚀性气体环境,特殊场景需咨询方成技术支持;
  5. 参数验证:批量使用前抽样测试电感值(22μH±20%),确保符合设计要求。

FC-SE2918-220M凭借低损耗、高电流与可靠性能,成为中高端电力电子领域的优选功率电感,可满足多场景高效稳定运行需求。

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
