FTC303020D1R5MBCA 是长江微电(cjiang)推出的一款表面贴装功率电感,封装尺寸 3.0×3.0mm(SMD),额定电感值 1.5µH,公差 ±20%。该器件针对空间受限且对大电流和低损耗有严格要求的开关电源及功率管理应用而设计,兼顾体积、抗饱和能力与导通损耗,适合主流降压转换器(Buck)、电源模块及点到点供电场景。
说明:基于 DCR 的直流损耗示例:若以额定电流 6.3A 连续工作,近似铜损 P = I^2·DCR ≈ 6.3^2×0.019 ≈ 0.75W,设计时应考虑热量管理与散热路径。
总结:FTC303020D1R5MBCA 以其 3×3mm 的小型化封装、大电流能力与较低的 DCR,为空间受限但需高效率与高电流通道的电源设计提供了平衡的方案;在实际应用中应重视热管理与电流裕度,以保证长期稳定运行。若需更详细的电气特性曲线、封装图与回流推荐,请向长江微电获取完整规格书。

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.
