FTC252010SR47MBCA 功率电感产品概述

FTC252010SR47MBCA是长江微电(cjiang)推出的一款小型化SMD贴片功率电感,专为高密度PCB设计中的中高电流电源场景优化,具备小体积、低损耗、高电流密度等核心特点,可广泛适配消费电子、便携式设备及汽车电子等领域的电源需求。

一、产品基本定位

该电感属于长江微电功率电感系列,采用表面贴装(SMD)工艺,封装尺寸紧凑(2×2.5mm),核心定位是解决小体积与中高电流承载能力的平衡问题——既满足便携式设备对PCB空间的严苛要求,又能稳定支撑5-7A的中功率电源场景,是高密度电子系统的理想电感选型。

二、核心电气参数详解

作为功率电感,其电气参数直接决定应用场景适配性,关键参数如下:

  1. 电感值与精度:标称电感值470nH,精度±20%——满足工业级功率应用对电感值的基本要求,无需超高精度即可稳定实现DC-DC转换、滤波等功能;
  2. 额定电流(Irms):6.1A——指电感在额定温度(125℃)下可连续稳定工作的均方根电流,此时电感值变化不超过10%,是持续负载场景的核心参考;
  3. 饱和电流(Isat):6.9A——磁芯饱和时的临界电流(电感值下降约30%),可应对脉冲负载(如CPU突发功耗、LED启动电流波动),避免磁芯饱和导致的电路异常;
  4. 直流电阻(DCR):15mΩ——低DCR设计显著降低铜损,减少电感自身发热,提升电源转换效率(如在5V转3.3V的降压电路中,损耗可控制在1%以内);
  5. 封装尺寸:SMD 2×2.5mm(对应2520封装)——长宽2.0mm×2.5mm,高度约1.0mm,兼容主流回流焊工艺,适配自动化生产。

三、工艺与可靠性特点

  1. 磁芯与绕线工艺:采用高性能铁氧体磁芯+漆包线绕制,磁芯饱和特性稳定,绕线工艺紧凑,确保小体积下的电流承载能力;
  2. 环保与耐温性:引脚采用无铅工艺,符合RoHS环保标准;耐焊接温度可达260℃/10s,适配常规SMT生产流程;
  3. 机械稳定性:封装结构牢固,引脚与磁芯结合紧密,可承受振动、冲击等环境应力(符合消费电子/汽车电子可靠性标准)。

四、典型应用场景

该电感的参数特性使其适配多类中高电流、小体积需求场景:

  1. 消费电子:智能手机、平板电脑的CPU/内存供电DC-DC降压电路(如5V转1.8V/2.5V);
  2. 便携式设备:蓝牙耳机、智能手表的电源管理模块(低DCR降低待机功耗);
  3. 汽车电子:车载USB充电口、仪表盘背光电路的小功率电源(耐温性适配车载环境);
  4. 工业控制:小型PLC、传感器节点的低功耗电源(稳定承载脉冲负载);
  5. LED驱动:小功率LED背光、应急照明的恒流驱动电路(饱和电流应对启动浪涌)。

五、选型参考与注意事项

  1. 优势匹配:若需小体积+中电流(5-7A),该型号是理想选择;若需更高电流(10A以上),可选择长江微电同系列更大封装(如3030、4040);
  2. 精度适配:±20%精度满足大部分功率应用,若需高精度(±10%),需切换至长江微电高精度电感系列;
  3. 温度考量:额定电流基于125℃环境,若实际工作温度低于125℃,可适当提升负载电流(需参考降额曲线);
  4. PCB设计:需确保电感焊盘与PCB走线匹配(避免走线过细导致额外损耗),并预留散热空间(虽DCR低,但大电流下仍需注意)。

总结:FTC252010SR47MBCA以紧凑封装实现了中高电流承载能力与低损耗的平衡,是消费电子、便携式设备等领域高密度电源设计的高性价比选择。

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
