SMMS1040-100M 功率电感产品概述

SMMS1040-100M是顺翔诺(SXN)推出的贴片式功率电感,针对中功率电源电路设计,以紧凑封装实现稳定储能与滤波功能,适配多种电子设备的电源模块场景。以下从核心参数、封装特性、电气性能及应用等维度展开详细概述。

一、核心参数精准梳理

该电感的关键技术参数明确,覆盖中功率电路的基础需求:

  • 电感值:10μH,为功率电路提供稳定储能容量;
  • 精度:±20%,满足大多数非超精密电源应用的误差要求;
  • 额定电流(Is):5.5A,指电感在额定工作温度下允许的最大连续电流,保证长期可靠性;
  • 饱和电流(Isat):8.5A,磁芯饱和时电感值下降至指定阈值(行业常规20%)的临界电流,为瞬态过载提供缓冲;
  • 直流电阻(DCR):37mΩ,低导通电阻可降低功率损耗,提升电源转换效率。

二、封装与物理特性

SMMS1040-100M采用表面贴装(SMD)工艺,物理尺寸为11.5×10×4mm(长×宽×高),属于紧凑型贴片封装:

  • 尺寸适配高密度PCB布局,可减少电源模块占用空间,适合小型化电子设备;
  • 贴片式设计支持自动化贴装生产,提升下游厂商生产效率;
  • 品牌为顺翔诺(SXN),具备工业级品质管控基础,参数一致性较好。

三、电气性能深度解析

各参数的实际表现直接影响电源电路的稳定性与效率:

  1. 电感值与精度:10μH的电感量可满足DC-DC转换器的储能需求,±20%精度虽不支持超精密应用,但覆盖消费电子、工业控制等多数场景,且降低工艺成本;
  2. 额定电流与饱和电流:5.5A额定电流保证连续工作时电感温升可控(行业常规≤40K),避免磁芯过热老化;8.5A饱和电流比额定电流高3A,可应对开关电源启动瞬态尖峰电流,防止电感失效;
  3. 低直流电阻:37mΩ的DCR显著降低导通损耗——例如5A工作电流下,损耗仅为0.925W,远低于高DCR电感,有助于提升电源效率并减少发热。

四、典型应用场景

基于参数特性,SMMS1040-100M适用于以下场景:

  1. 开关电源(DC-DC转换器):笔记本电脑、显示器、机顶盒等设备的电源模块,5.5A额定电流覆盖中功率需求,低DCR提升续航;
  2. 车载电子:12V/24V车载系统的辅助电源(如音响、导航),饱和电流冗余设计可应对车载电压波动与瞬态电流;
  3. 工业控制:PLC、伺服驱动器的小功率电源部分,贴片封装适配集成化设计,稳定参数满足工业级可靠性;
  4. 通信设备:路由器、交换机的电源模块,紧凑尺寸适配高密度布局,低损耗保证长期稳定运行。

五、选型与应用优势总结

对比同类同参数级别的功率电感,SMMS1040-100M具备以下优势:

  • 紧凑封装与高集成度:11.5×10×4mm尺寸在同电流等级中属于小型化设计,节省PCB空间;
  • 效率与可靠性平衡:低DCR提升电源效率,高饱和电流增强瞬态过载能力,降低故障风险;
  • 成本与性能适配:±20%精度满足多数应用需求,同时控制生产与采购成本,适合量产;
  • 贴片工艺兼容性:支持自动化贴装,适配下游规模化生产流程,减少人工成本。

综上,SMMS1040-100M是一款针对中功率电源电路优化的贴片功率电感,以稳定性能、紧凑封装及高性价比,成为消费电子、车载、工业控制等领域的实用选型。

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
