FTC252010S1R0MBCA 产品概述

一、产品简介

FTC252010S1R0MBCA 是长江微电(cjiang)推出的一款表贴功率电感,电感量为 1 μH,公差 ±20%,面向中高电流功率管理应用。该器件采用小型 SMD 封装,外形尺寸为 2.0 × 2.5 mm,设计用于在体积受限的电路板上实现高功率密度的滤波和能量存储。

二、主要参数

  • 电感值:1 μH(±20%)
  • 额定电流(Irms):4.5 A(连续工作时参考值)
  • 饱和电流(Isat):5.3 A(在此电流下电感值明显下降)
  • 直流电阻(DCR):约 25 mΩ
  • 封装:SMD,尺寸 2.0 × 2.5 mm
  • 品牌:cjiang(长江微电)
    (以上参数为选型参考,具体测试条件请以厂家数据表为准)

三、性能亮点

  • 高电流承载:额定电流 4.5A、饱和电流 5.3A,使其在中小功率降压转换器和输出滤波中能稳定工作,不易磁饱和。
  • 低功耗损耗:25 mΩ 的低 DCR 有利于减少 I^2R 损耗和温升,提高能效,适合对效率敏感的便携与工业电源。
  • 小型化封装:2×2.5 mm 的 SMD 封装便于在高密度 PCB 布局中节省空间,适合移动设备、电源模块和紧凑型电源设计。
  • 通用公差:±20% 常见于功率电感,便于在电源滤波和电感选择时与电路匹配。

四、典型应用

  • 同步/非同步降压转换器(buck)输出滤波和能量存储
  • 电源管理模块(PMIC)和点对点供电(VRM/POP)
  • 移动设备、平板、笔记本电源方案
  • LED 驱动与背光电源滤波
  • 工业控制与通信设备中的电源滤波与去耦

五、封装与安装建议

  • 焊接:适配无铅回流焊工艺,建议遵循厂家提供的回流温度曲线以保证焊点可靠性。
  • PCB 布局:为降低寄生阻抗和热阻,建议靠近电源开关器件布置,走短且宽的铜箔连接;尽量避免在电感下方放置敏感信号线。
  • 散热与压板:虽然功率电感自身非主要散热体,但合理的铜皮扩展和必要时增加过孔有助于热量扩散,减小温升。
  • 机械可靠性:在贴装和波峰/回流焊后,应避免在器件上施加过大机械应力,以防损伤内部绕组或磁芯。

六、选型与设计注意

  • 确认实际工作环境中的峰值电流与纹波电流,保证不超过 Isat 和额定电流,以免产生过大电感下降和温升。
  • 若对电感精度、温度系数或自谐频率有严格要求,应参考完整数据表并考虑样件测试。
  • 如需更低 DCR 或更高饱和电流,可考虑更大封装或同系列不同规格型号。

七、结论

FTC252010S1R0MBCA 以其 1 μH 的电感量、4.5A 额定电流与 5.3A 的饱和电流,以及小巧的 2×2.5 mm SMD 封装,适合中高电流、空间受限的电源管理场景。其低 DCR 特性有助于提升效率并降低温升,是移动电源、模块化电源和一般电源滤波设计中的实用选择。欲获取更详细的电气特性、温升曲线与推荐焊盘尺寸,请查阅长江微电官方数据手册或联系供应商技术支持。

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
