FTC252012SR24MBCA 产品概述

一、产品简介

FTC252012SR24MBCA 是长江微电(cjiang)推出的一款低直流电阻、高电流承载能力的贴片功率电感。封装尺寸为 SMD 2.0×2.5 mm,额定电流 8A,磁饱和电流(Isat)9.3A,标称电感值 240 nH,公差 ±20%,直流电阻(DCR)约 10 mΩ。该器件专为中大电流点位(Point-of-Load)以及同步降压等电源应用设计,兼顾体积、热性能与电性能。

二、主要规格(关键信息)

  • 电感值:240 nH ±20%
  • 额定电流:8 A(连续载流能力,受温升与散热条件影响)
  • 饱和电流 Isat:9.3 A(厂家定义的饱和点电流)
  • 直流电阻 DCR:约 10 mΩ
  • 封装:SMD,2.0 × 2.5 mm
  • 品牌:cjiang(长江微电)

三、性能亮点

  • 小尺寸高电流:2×2.5 mm 的紧凑封装适合高密度板级布置,同时支持 8A 的连续电流,适合多相或串并联应用。
  • 低损耗:10 mΩ 的低 DCR 有利于减少铜耗,降低转换器的功率损耗与温升。
  • 宽松公差:±20% 公差适配高开关频率时的滤波与能量储存需求,兼容多种磁芯工艺。
  • 良好饱和特性:9.3A 的饱和电流为瞬态电流提供裕量,有利于短时负载冲击的稳定性。

四、典型应用场景

  • 同步降压 DC-DC 转换器(点位电感)
  • 多相电源模块与服务器电源管理
  • 通信设备、消费电子的电源滤波与储能
  • LED 驱动、工业电源与电池管理系统

五、设计与使用建议

  • 散热与布局:为发挥额定电流能力,建议靠近开关 MOSFET 与电容布置,缩短回流环路并加宽走线;在多层板中利用过孔引入散热层或铜铺设以降低温升。
  • 电流裕量:额定电流 8A 为长期工作限制,若存在较大瞬态或脉冲电流,应参考 Isat 9.3A 并预留安全裕量。
  • 损耗估算:静态铜耗近似为 P ≈ I_rms^2 × DCR;例如在连续 8A 条件下,P ≈ 8^2 × 0.01Ω ≈ 0.64W(实际 RMS 与温度影响需校正)。
  • 焊接工艺:建议采用标准无铅回流工艺进行贴装,遵循元件及基板的热循环限制,避免重复高温导致性能漂移。

六、可靠性与测试

该类功率电感通常需通过温升测试、浪涌电流测试与环境可靠性试验(高低温循环、湿热试验)以验证在目标应用下的寿命与稳定性。实际使用时建议在样机上进行热成像与长时运行验证。

七、选型要点

  • 如果系统对体积有严格限制且工作电流接近 5–8A,FTC252012SR24MBCA 是优选;若电流常态超过 8A 或要求更低电感误差,应选用更大封装或更高 Isat 的型号。
  • 对于对 DCR 和效率要求极高的设计,可考虑并联电感或选型更低 DCR 的功率电感以降低铜耗。

总结:FTC252012SR24MBCA 以紧凑封装、较低的 DCR 和较高的饱和电流性能,适合点位电感与中大电流 DC-DC 应用。在实际设计中应结合散热、版图与实际负载特性进行验证,以确保长期稳定运行。

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
