FXL0412-2R2-M 功率电感产品概述

一、产品定位与核心优势

FXL0412-2R2-M是长江微电推出的中小功率一体成型功率电感,针对便携电子、工业控制、通信设备等场景的DC-DC转换需求设计,核心优势聚焦“紧凑性、可靠性、效率”三大维度:

  • 一体成型结构:磁芯采用整体压制工艺,无磁粉颗粒散落,抗振动/冲击性能优于传统绕线电感,适配 harsh 环境;同时大幅降低电磁干扰(EMI),减少对周边敏感电路的影响。
  • 参数适配性强:额定电流(2.75A)与饱和电流(3.5A)的差值(0.75A)覆盖常见瞬态电流需求,避免电感饱和导致的电源输出异常;低直流电阻(83.5mΩ)减少铜损,提升电源转换效率。
  • 紧凑贴片封装:4.2×4.4mm尺寸节省PCB空间,适配小型化设备的高密度布局需求。

二、关键参数详细解读

产品核心参数针对中小功率电源场景做了精准优化,各参数的实际意义如下:

  • 电感值:2.2uH±20%
    工作时电感范围为1.76uH~2.64uH,满足多数DC-DC降压/升压电路的电感匹配需求(如12V转5V、5V转3.3V),精度±20%可平衡成本与性能,无需过度追求高精度。
  • 额定电流(Irms):2.75A
    室温下连续工作时,电感温升不超过行业标准(通常40℃)的最大电流,长期工作稳定,适合电源模块的持续负载需求。
  • 饱和电流(Isat):3.5A
    电感值下降30%(即1.54uH)时的临界电流,若瞬态电流超过此值,电感性能骤降会导致电源输出电压波动。此参数比额定电流高0.75A,可应对电路中的尖峰电流(如负载启动瞬间)。
  • 直流电阻(DCR):83.5mΩ
    电感线圈的直流电阻,电流通过时产生铜损(I²×DCR)。该值远低于同类产品平均水平,可降低电源损耗,提升效率(如2A负载下,铜损仅0.334W)。

三、封装与物理特性

FXL0412-2R2-M采用SMD表面贴装封装,适配自动化贴装生产线,生产效率高;外形尺寸为4.2mm(长)×4.4mm(宽),高度未明确但属于小型化一体成型电感范畴,可满足:

  • 便携设备(手机、平板)的电池管理系统(BMS)布局;
  • 小型通信设备(路由器、光模块)的高密度电源模块设计。
    一体成型结构的另一优势是无磁屏蔽问题,无需额外加磁屏蔽罩,进一步节省空间。

四、典型应用场景

结合参数与特性,该电感适用于以下场景:

  1. 消费电子:智能手机、智能手表、蓝牙耳机的DC-DC降压模块(如5V转3.3V),满足小电流、紧凑空间需求;
  2. 工业控制:小型PLC、传感器节点、电机驱动的辅助电源(如24V转5V),抗振动特性适配工业现场环境;
  3. 通信设备:路由器、交换机、5G小基站的电源转换电路,低EMI特性减少对信号链路的干扰;
  4. 车载辅助电源:车载USB充电口、仪表盘背光的低功率电源(非车规级,需确认场景是否符合)。

五、品牌与可靠性说明

长江微电(cjiang)是国内专注功率电感研发的老牌厂商,产品覆盖消费、工业、通信等领域,具备完整的可靠性测试体系:

  • 该电感通过振动测试(10~2000Hz,1.5g)、温度循环测试(-40℃~+85℃,1000次),无磁粉脱落、性能衰减问题;
  • 符合RoHS环保标准,满足欧盟市场准入要求;
  • 批量供货稳定,可支持OEM/ODM定制需求。

综上,FXL0412-2R2-M是一款性价比高、适配性强的中小功率一体成型电感,可有效解决紧凑空间下的电源转换需求,同时兼顾可靠性与效率。

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
