FTC322512S3R3MBCA 产品概述

一、产品简介

FTC322512S3R3MBCA 为长江微电(cjiang)推出的一款功率贴片电感,封装尺寸为 2.5 × 3.2 mm,标称电感值 3.3 μH,公差 ±20%。该器件面向中等电流、空间受限的开关电源与电源滤波场景,兼顾体积与导通能力,适合表贴自动化生产。

二、主要电气参数

  • 电感值:3.3 μH(±20%)
  • 额定电流(Irated):2.9 A(持续允许电流)
  • 饱和电流(Isat):3.7 A(电感显著下降前的参考值)
  • 直流电阻(DCR):75 mΩ(典型)
    这些参数表明器件适用于约 2–3 A 级别的点载流与中小功率降压/升压转换器。

三、产品特点与优势

  • 小型化:2.5×3.2 mm 封装,节省 PCB 面积,适合集成化设计。
  • 中等电流承载:2.9 A 额定电流满足常见 PoL(Point-of-Load)与输入/输出滤波需求。
  • 工艺兼容:SMD 型式便于回流焊接与自动化贴装,提高生产效率。
  • 较低 DCR:75 mΩ 在同尺寸器件中具有竞争力,但在高电流下仍需关注功耗。

四、典型应用

  • 手机/平板/便携式设备的电源模块与点载电源
  • DC-DC 降压/升压转换器(中小功率)
  • 输入/输出滤波器、电源整流后端滤波
  • 工业控制与通信设备的局部稳压电源

五、使用建议与版图要点

  • 电流和热管理:在额定电流 2.9 A 下,近似直流损耗 P = I^2·DCR = 2.9^2×0.075 ≈ 0.63 W;设计时需保证足够的铜箔散热与通孔/散热层以降低结温。
  • 工作裕量:尽量将工作电流控制在额定值以下,并留有裕量避免长期接近 Isat(3.7 A),以防电感量下降影响环路稳定。
  • 布局建议:电感与开关器件、输入/输出电容尽量靠近,走短粗的 PCB 路径,保持完整的地平面以降低寄生与 EMI。
  • 焊接可靠性:遵循标准回流焊曲线与厂方焊接指南,避免超出推荐温度/时间导致性能退化。

六、注意事项与采购信息

  • 规格波动:电感值 ±20% 为典型公差,关键设计应以实际测量或更严公差器件为准。
  • 测试与验证:在最终电路中进行热循环、寿命与电流应力测试,验证在预期工作条件下的稳定性。
  • 订购:型号 FTC322512S3R3MBCA,品牌:长江微电(cjiang);采购时确认包装形式、出货卷带或托盘及批次信息。

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
