FTC404012S2R2MBCA 产品概述

FTC404012S2R2MBCA 是 cjiang(长江微电)推出的一款小型化一体成型功率电感,采用T‑CORE结构与扁线绕制工艺,体积小、散热好,适用于中高密度开关电源及点载负载场合。凭借较低的直流电阻与较高的额定电流能力,在体积与性能之间取得良好平衡,能有效提升电源效率并降低温升。

一、主要特性

  • 感值:2.2 μH,公差 ±20%
  • 额定电流:5.0 A(持续工作)
  • 饱和电流(Isat):6.5 A(感值下降到指定比例时的参考)
  • 直流电阻(DCR):45 mΩ(典型)
  • 结构:小型一体成型T‑CORE,扁线工艺,感值偏小设计
  • 封装:SMD,外形尺寸 4.1 × 4.1 mm
  • 品牌:cjiang(长江微电)

二、性能与优势

  • 小体积一体成型:节省PCB空间,适合集成度高的电源模块与移动设备。
  • 扁线工艺:线径较大、截面积均匀,有利于降低DCR、减小铜损和温升,同时改善交流损耗特性。
  • 高电流能力:5A额定电流与6.5A饱和电流可满足中大电流点载应用,具有更好的动态负载响应。
  • 稳定性好:T‑CORE结构在磁路闭合和机械强度上优势明显,有利于抑制振动与电磁干扰。

三、典型应用场景

  • DC‑DC 降压/升压转换器(尤其是点对点电源、VRM)
  • 电源模块与电源管理模块(PMIC)中的能量储存与滤波
  • LED 驱动电源、车载电子(对环境适配需参照车规认证)
  • 通信设备与消费电子中的电源前端滤波或储能元件

四、封装与焊接建议

  • 封装为SMD贴片,建议按厂商推荐的PCB焊盘布局进行布局,以保证良好焊接质量与散热路径。
  • 兼容常规回流焊工艺,但需注意温度曲线与湿敏等级(请参照产品数据手册)。
  • 布局时尽量缩短与功率开关器件的连线,优化回流环路以降低EMI;必要时配合输入输出旁路电容和磁屏蔽设计。

五、选型与注意事项

  • 根据系统最大峰值电流选择额定电流与饱和裕量,确保在瞬态情况下不进入饱和区。
  • 考虑DCR对效率的影响:45 mΩ在多数中高电流场合具备较好表现,但对极高效率要求应权衡。
  • 温升评估:在目标电流下进行热仿真或样机测试,确认工作温度符合系统可靠性要求。
  • 若用于汽车或工业级应用,建议向厂商确认温度等级、振动、寿命及相关认证信息。

FTC404012S2R2MBCA 以小体积、高电流处理能力和低DCR为主要卖点,适合对体积和效率有较高要求的电源设计。最终设计中建议结合实际工作频率、负载波形与热环境做样机评估,确保长期稳定可靠运行。若需数据手册或详细电气特性曲线,请联系长江微电官方获取完整资料。

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
