SMMS1385-470MT 功率电感产品概述

一、产品核心定位与应用场景

SMMS1385-470MT是顺翔诺(SXN)推出的一款SMD贴片功率电感,聚焦中功率电源电路的高电流承载、低损耗及易集成需求,适用于车载、工业、消费电子等多领域的常规功率电感应用。其设计兼顾性能与成本,是DC-DC转换器、电源模块等场景的常用基础元件,可替代同类进口或国产中功率电感。

二、关键参数解析

该电感的核心参数直接决定了其应用适配性,具体解析如下:

  1. 电感值与精度:额定电感值47μH,精度±20%——符合功率电感对电感稳定性的基本要求,可适配大多数DC-DC转换器的电感选型范围(无需过高精度即可满足电源纹波控制);
  2. 电流承载能力:
    • 额定电流(Irms)5A:指电感连续工作时,电感值变化≤10%、温升在允许范围内的最大电流,是实际电路设计的核心参考;
    • 饱和电流(Isat)8A:电感值下降约30%(行业常规定义)时的极限电流,反映抗饱和能力——8A的饱和电流可应对电路瞬态过流或负载波动,降低失效风险;
  3. 直流电阻(DCR):72mΩ——绕组的直流电阻,低DCR可大幅降低铜损,提升电源转换效率(减少发热,延长电路寿命);
  4. 封装尺寸:13.8×12.8×8.80mm(长×宽×高)——贴片功率电感的标准尺寸,兼容常规SMT产线。

三、封装与尺寸说明

该电感采用SMD贴片封装,尺寸紧凑(13.8mm长×12.8mm宽×8.80mm高),可节省PCB布局空间,适合高密度集成的电源模块设计。

  • 封装设计适配常规SMT贴装流程,焊接温度建议控制在260℃/10s以内(避免高温损坏绕组绝缘);
  • 引脚间距符合行业标准,可与其他贴片元件协同布局,提升电路集成度(无需特殊设计即可嵌入多数电源板)。

四、性能优势与特点

  1. 高电流密度:额定5A、饱和8A的电流能力,可满足50W以内中功率电源需求(无需并联多个小电感,简化电路设计);
  2. 低损耗高效:72mΩ的低DCR配合磁芯材料优化,可将电源转换效率提升至90%以上(具体依电路拓扑而定);
  3. 宽温适应性:耐温范围-40℃至125℃(顺翔诺该型号符合车载/工业级标准),可适应高低温环境(如车载冬季低温、工业高温车间);
  4. 可靠性稳定:磁芯与绕组采用固封工艺,抗振动、抗冲击性能良好(可满足工业设备7×24小时运行需求);
  5. 成本可控:兼顾性能与成本,适合批量生产的电源产品选型(性价比优于同类进口电感)。

五、典型应用示例

  1. 车载电源:车载充电器(12V转5V/9V/12V)、汽车中控电源、LED车灯驱动电源;
  2. 工业电源:PLC辅助电源、伺服驱动器DC-DC模块、工业开关电源;
  3. 消费电子:65W-100W快充充电器、智能电视电源、LED显示屏驱动;
  4. 通信设备:基站电源模块、路由器/交换机电源、光模块辅助电源。

综上,SMMS1385-470MT凭借高电流承载、低损耗、易集成等特点,成为中功率电源领域的高性价比选型,可覆盖多行业的常规功率电感需求。

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
