FTC303020D1R0MBCA是长江微电(cjiang)推出的一款小型化贴片功率电感,针对中小功率电源电路的储能与滤波需求设计,凭借紧凑封装、高电流承载能力及低损耗特性,在便携式电子、车载电子等领域具备广泛应用潜力。
该电感定位于中等电流密度的电源级应用,核心目标是在3x3mm的小型封装内,平衡“高电流承载”与“低损耗”两大需求——既满足便携式设备对空间的严格限制,又能支撑DC-DC转换器、LED驱动等电路的稳定工作,避免因电感饱和或损耗过高导致的效率下降、温升超标问题。
电感标称值为1uH±20%,精度20%符合电源类电感的典型需求(无需射频级的高精度),可适配Buck/Boost等DC-DC拓扑的电感值计算(如输入12V转5V、输出2A的Buck电路,电感值通常在0.47~10uH区间)。
DCR为14mΩ,属于同尺寸3x3封装电感中的低损耗水平——以额定电流6.5A计算,铜损仅为6.5²×0.014≈0.59W,远低于同电流竞品的平均损耗(约0.7~0.8W),能有效提升电源转换效率。
该电感采用3x3mm SMD贴片封装,属于小型化表面贴装器件,具备以下特点:
与市场同尺寸(3x3mm)功率电感相比,FTC303020D1R0MBCA的核心优势体现在:
该电感可广泛应用于以下领域:
总结:FTC303020D1R0MBCA是一款“小体积、高电流、低损耗”的贴片功率电感,适配多场景电源需求,尤其适合对空间和效率有双重要求的便携式与车载电子领域,是替代进口同类型器件的高性价比选择。

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.
