FTC404012S5R6MBCA 是长江微电(cjiang)推出的一款小型化一体成型T‑CORE贴片电感,封装尺寸为SMD 4.1×4.1mm。该型号采用扁线工艺与一体成型结构,实现体积小、散热与电流能力相对优化的设计。标称电感值为 5.6 μH,公差 ±20%,额定电流 3.0 A,饱和电流(Isat)4.5 A,直流电阻(DCR)116 mΩ,适用于对体积要求严格且需中等电流通断的开关电源与滤波场合。
在选择时,若系统对直流损耗敏感或需更高连续电流,可考虑 DCR 更低、额定电流更高的同类器件;若对电感精度要求高,可选择公差更严格的型号或配合并联/分拆电感方案。最终选型建议以完整的器件数据表为准,并结合实际温升测量与寿命验证。
备注:本文基于FTC404012S5R6MBCA 的主要参数与通用电源电感设计经验给出建议,具体详细电气测试条件与封装机械图请参见厂方数据手册或联系长江微电获取正式技术资料。

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.
