FTC252012SR47MBCD是长江微电(cjiang)推出的一款紧凑型贴片功率电感,主打「小空间大电流」的高密度电源设计需求。它采用SMD贴片封装,尺寸为2×2.5mm(长×宽,实际高度约1.2mm,对应行业252012封装命名规则),属于微型功率电感范畴,能在极小PCB空间内实现高电流承载能力,是消费电子、车载电子等领域的实用电源配套元件。
这款电感的核心参数直接决定了其应用场景,以下是关键参数的通俗解析:
电感值为470nH,精度±20%。470nH是中低频功率电路的常用值,能满足DC-DC转换器、降压/升压电路的电感滤波需求;±20%的精度在功率电路中属于合理范围——既保证了电路性能稳定,又避免了过高的制造成本。
DCR为13mΩ,属于低阻值范畴。低DCR意味着电感导通损耗小:以8A电流为例,损耗仅为(I^2R=8^2×0.013=0.832W),比普通20mΩ电感的损耗降低35%,能有效减少发热、提升电源转换效率,同时延长产品寿命。
SMD贴片封装,尺寸2×2.5mm,适合自动化SMT流水线贴装,生产效率高;紧凑尺寸可节省30%以上的PCB空间,尤其适合智能手机、车载控制器等对空间要求严格的产品。
长江微电(cjiang)是国内专注功率电感研发的厂商,这款电感具备以下可靠性优势:
这款电感的参数特性使其适配多种高密度功率电路:
综上,FTC252012SR47MBCD是一款针对高密度电源设计的高性价比功率电感,小封装、大电流、低损耗的特性使其在消费电子、车载等领域具备较强竞争力。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
