FTC252008S2R2MBCA — 3A 2.2µH 功率电感器产品概述

一、产品简介

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。

二、主要特性

  • 电感值:2.2µH ±20%
  • 额定/饱和电流:3A(Irated / Isat)
  • 直流电阻(DCR):约 77mΩ(典型)
  • 封装形式:SMD,尺寸 2.0 × 2.5 mm
  • 适用场景:电源转换、输出滤波、EMI 抑制、小型功率模块

三、性能与应用建议

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)。

四、布板与热管理要点

  • 布局靠近开关节点,缩短进出线的走线长度,减小寄生电感和辐射。
  • 为减低温升和 DCR 损耗,可在电感下方或周边配合散热铜箔/平面,必要时添加过孔导热至内层或底层。
  • 与敏感模拟信号隔离,避免开关噪声耦合到高阻节点。
  • 焊接工艺采用无铅回流,遵循厂商推荐回流曲线以防引脚或结构损伤(具体回流参数请参照长江微电器件资料)。

五、选型与验证注意事项

  • 实际电感会随直流偏置(DC)和频率变化,建议在目标电路和工作点下测量真实电感值与损耗。
  • DCR 直接影响效率与温升,频繁处于接近额定电流时应校核温升与寿命。
  • 若电路有较大纹波电流或脉冲峰值,需关注电感的饱和特性与磁饱和后电感值下降对电路稳定性的影响。
  • 订购与库存时注意包装(卷带)与保管条件,避免长时间潮湿导致焊接问题。

六、典型应用举例

  • 移动电源 / USB PD 降压模块的输出滤波与储能元件
  • 手机、蓝牙设备、可穿戴设备的次级电源滤波
  • 工业类低功率开关电源、功率管理模组的输入/输出滤波

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。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
