FTC322512SR68MBCA 产品概述

一、概述

FTC322512SR68MBCA 是长江微电(cjiang)推出的一款面向中高电流开关电源和电源管理模块的表面贴装功率电感器。器件外形为 SMD 封装,尺寸为 2.5 × 3.2 mm,标称电感值 680 nH,公差 ±20%,具有较低直流电阻和较高额定电流能力,适合用于降压转换器的能量储存与滤波环节。

二、主要电气参数

  • 电感值(L):680 nH(0.68 µH),公差 ±20%
  • 额定电流(Irated / I RMS):7.3 A(持续工作条件下推荐值)
  • 饱和电流(Isat):8.1 A(在此电流水平下电感值降至额定值的指定百分比)
  • 直流电阻(DCR):18 mΩ(典型值,影响功耗与温升)
  • 封装:SMD,外形尺寸 2.5 × 3.2 mm(便于高密度 PCB 布局)
    以上参数为器件典型规格,实际值会随工作温度和直流偏置电流发生变化,选型时应考虑 DC-bias 和温升影响。

三、产品特点与优势

  • 小尺寸高电流:2.5×3.2 mm 的紧凑封装在保持高电流能力(7.3 A)同时,有利于减小电源模组体积。
  • 低 DCR:约 18 mΩ 的低直流电阻可降低铜损,提升效率并减少器件发热。
  • 高饱和电流裕量:8.1 A 的饱和电流保证在瞬态或峰值负载情况下仍能维持较稳定的电感特性。
  • SMD 工艺兼容:适配常见 SMT 贴装与回流焊工艺,便于自动化生产与可靠装配。
  • 适用广泛:适合用于移动电源、笔记本、机顶盒、路由器、工业电源、车载电子(在满足相关可靠性与认证要求下)等电源转换与滤波场景。

四、典型应用场景

  • 同步/非同步降压(Buck)转换器的电感储能元件。
  • 输出滤波电感,用于降低输出纹波电流与电压。
  • 多相电源模块的相间电感选择,支持高电流分配。
  • 功率管理子系统中的能量转移与抑制电磁干扰(EMI)用途。

五、PCB 布局与使用建议

  • 靠近开关管与二极管/功率 MOSFET:将电感尽量靠近开关器件与输出电容,最小化开关回路面积以降低 EMI。
  • 宽短铜箔与良好散热:为降低铜损并帮助散热,建议使用宽且短的连接线,必要时在电感下方或附近增加散热铜箔及热铜柱/过孔。
  • 输入输出电容靠近布置:输入侧和输出侧的去耦电容应尽量靠近电感与开关器件放置以优化性能。
  • 考虑 DC-bias 影响:在实际电流工作点下电感值会下降,选型时应参考器件电感随直流偏置曲线并留有裕量。
  • 回流焊兼容:器件适用于标准 SMT 回流焊流程(建议遵循制造商的焊接温度曲线和 JEDEC 推荐规范)。

六、可靠性与选型注意事项

  • 温升与功耗:基于 DCR 与工作电流计算功耗 P = I^2·DCR,并评估温升与长期可靠性。
  • 峰值与脉冲电流:若系统存在较大脉冲电流或短时峰值,应确保峰值电流不超过 Isat,以免电感饱和影响性能。
  • 环境与认证:若用于车规或工业级场景,请向供应商确认是否有相应的可靠性测试、温度等级与认证(如车规 AEC-Q 等)。
  • 合规性:多数制造商会提供 RoHS 等环保合规声明,具体合规证书请向供应商索取。

七、采购与技术支持

FTC322512SR68MBCA 为长江微电(cjiang)系列功率电感产品,订购时请确认完整料号与包装形式(卷装、带盘等)、批次与规格书。对于大批量应用或特殊环境(高温、汽车级)要求,建议与厂家或授权分销商沟通样片测试、生命周期支持与长期供货保障。

如需器件详细的电感随频率/电流/温度的典型曲线、机械尺寸图或回流焊工艺建议,可联系供应商获取完整规格书与应用说明。

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
