SMMS1050-2R2M功率电感产品概述

一、产品定位与核心价值

SMMS1050-2R2M是顺翔诺(SXN)推出的大电流低损耗表面贴装功率电感,针对电源系统的储能、滤波及EMI抑制需求设计,核心价值聚焦于「高电流承载能力+低损耗发热+紧凑封装适配」,可覆盖工业、车载、消费电子等多领域的中等功率应用场景。

二、关键电气性能参数解析

1. 电感特性与精度

电感值为2.2μH±20%,属于功率电感常用规格,精度满足工业级设备(±20%)的滤波/储能需求,无需额外校准即可适配常规DC-DC转换器、LED驱动等电路。

2. 电流承载能力

  • 额定电流(Irms):13A:指电感持续工作时,自身温度上升≤40℃(行业标准)的最大电流,可稳定支撑中等功率负载(如65W快充、100W车载充电器)的持续输出;
  • 饱和电流(Isat):20A:电感值下降30%时的临界电流,是重载启动、瞬间负载波动(如电机启动、电池快充峰值)的关键保障——当系统峰值电流≤20A时,电感不会因磁芯饱和导致性能突变,避免电源失效。

3. 低损耗特性

直流电阻(DCR):8.2mΩ:采用粗线径漆包线绕制,大幅降低铜损(功率损耗公式:(P=I^2R))。以13A额定电流计算,单只电感损耗仅约1.4W,显著减少电源系统发热,提升转换效率(如快充效率可超90%)。

三、物理特性与封装规格

1. 封装与尺寸

  • 封装类型:SMD(表面贴装),适配自动化贴装生产线;
  • 外形尺寸:11.5mm×10mm(长×宽),属于紧凑型1050系列(行业通常以「长×宽」命名,如1050对应10mm×5mm,但本型号为定制化紧凑尺寸),高度约8mm(常规功率电感高度),可满足高密度PCB设计需求(如笔记本电源、服务器模块的紧凑布局)。

2. 结构与材料

采用铁氧体磁芯+多层漆包线绕制结构:铁氧体磁芯具备高饱和磁通密度,保障大电流下的稳定性;多层绕线减少趋肤效应(高频下电流集中在导线表面),进一步降低损耗。

四、典型应用场景

1. 消费电子电源

  • 大功率快充(65W/100W):12V转5V/3A输出端的滤波电感,低DCR降低充电器发热,饱和电流支撑快充峰值电流;
  • 游戏主机/显示器电源:12V转3.3V/10A输出,13A额定电流满足持续负载,2.2μH电感抑制纹波。

2. 车载电子系统

  • 车载充电器(QC3.0/PD快充):适配-40℃~+125℃车载温度范围,抗振动结构满足汽车行驶中的振动要求;
  • 电机控制器:无刷电机启动时的瞬间峰值电流(≤20A)可被饱和电流覆盖,避免电感失效。

3. 工业电源与设备

  • PLC(可编程逻辑控制器)电源模块:24V转5V/5A输出,稳定承载工业设备的持续负载;
  • 伺服驱动器:储能电感支撑电机的动态负载波动,提升系统响应速度。

五、可靠性与适用环境

1. 温度适应性

工作温度范围为**-40℃+125℃**,满足工业级(-40℃+85℃)及车载级(-40℃~+125℃)环境要求,可在极端温度下长期稳定工作。

2. 焊接与抗振动

  • 焊接兼容性:适配回流焊、波峰焊工艺,焊盘设计符合IPC-A-610标准,焊接可靠性高;
  • 抗振动性能:磁芯与绕线采用环氧树脂固定,可承受10G(10~2000Hz)的振动测试,满足运输及现场振动需求。

六、选型与使用注意事项

1. 电流匹配原则

  • 实际工作电流需≤13A(额定电流),避免长期过流导致电感过热老化;
  • 瞬间峰值电流需≤20A(饱和电流),否则可能因磁芯饱和导致电感值骤降,引发电源纹波超标、输出电压不稳定。

2. PCB设计要点

  • 电感下方避免走线:减少涡流损耗,提升电感效率;
  • 焊盘尺寸匹配:需预留足够焊盘面积(建议≥12mm×11mm),确保焊接强度;
  • 散热设计:13A工作时损耗约1.4W,需在PCB上增加散热铜箔或散热片,避免局部过热。

3. 并联使用建议

如需更大电流(如26A),可并联2只同型号电感,但需注意:

  • 电感值、DCR一致性需≤5%,避免电流分配不均;
  • 并联后电感值变为2.2μH/2=1.1μH,需根据电路需求调整。

SMMS1050-2R2M凭借「高电流、低损耗、紧凑封装」的综合优势,成为中等功率电源系统的高性价比选择,可有效降低系统设计复杂度,提升电源效率与可靠性。

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.
