FC-SE2014-220M是方成(FC)品牌针对中大功率电源电路设计的扁平线功率电感,采用SMD贴片封装,聚焦“高电流承载、低损耗、高可靠性”三大核心需求,适配服务器、工业控制、新能源等领域的自动化生产与严苛场景。
标称电感值为22μH,公差±20%,满足多数DC-DC转换器、滤波电路的电感量设计需求——公差范围可通过电路裕量计算覆盖,无需额外复杂补偿。
仅10.65mΩ,得益于扁平线绕制工艺:导线表面积大,高频趋肤效应影响小,相比同电感值的圆线电感DCR降低约25%-30%,可显著减少铜损,提升电源转换效率(每1A电流损耗仅约10mW)。
支持100kHz-2MHz的开关频率,覆盖主流DC-DC转换器(如Buck、Boost拓扑)的工作频段,满足中高频电源电路需求。
替代传统圆线,增加导线有效导电面积,降低高频损耗;导线间接触紧密,散热路径更短,热阻比圆线电感低约15%。
选用低损耗铁氧体合金复合磁芯,饱和磁通密度高,保证15A极限电流下仍能维持稳定电感特性,避免磁饱和导致的电路输出电压波动。
采用2014规格贴片封装(20mm×14mm×10mm,典型值),无外露引线,减少寄生电感(≤1nH)与电阻,提升电路高频响应;适配标准SMT生产线,焊接良率≥99%。
支持**-40℃至+125℃**,满足工业级(-40℃+85℃)、车载级(-40℃+125℃)场景,极端温度下性能无明显衰减。
符合RoHS、REACH标准,无铅环保;耐高温回流焊(峰值260℃,持续≤30秒),适配无铅焊接工艺,避免焊接缺陷。
磁芯与导线采用环氧树脂固定,通过振动测试(10-2000Hz,1.5G)与冲击测试(1000m/s²,11ms),适合车载、户外设备等振动场景。
FC-SE2014-220M通过“低损耗、高电流、高可靠”的性能组合,成为中大功率电源电路的高性价比选型,适配多行业的自动化生产与严苛场景需求。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
