FTC252008S2R2MBCA 是长江微电(cjiang)推出的一款小型表面贴装功率电感,标称电感值为 2.2µH,公差 ±20%,额定电流 3A,饱和电流(Isat)3A,直流电阻(DCR)约 77mΩ。封装为 SMD,外形尺寸 2.0×2.5mm,适用于对尺寸与电流承载有较高要求的移动电源、DC-DC 降压模块及电源滤波场合。
该器件面向中小功率开关电源应用。2.2µH 的量级适合常见降压(Buck)拓扑中作为储能与输出滤波电感,或用于输入侧去耦与噪声滤除。由于饱和电流与额定电流均标称为 3A,建议在实际设计中对电感的直流偏置效应进行评估,考虑到工作温度和电流波峰,实际使用电流最好有一定裕度(通常按 60%–80% 的安全系数设计)。
如需更详细的电气特性曲线、温度范围、回流焊规范或封装图纸,请直接参考长江微电(cjiang)提供的产品规格表与样品测试报告,以便在具体设计中获得最佳性能与可靠性。

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.
