SMMS1350-2R2M 功率电感产品概述

一、产品基本信息

  • 品牌:顺翔诺(SXN)
  • 型号定义:SMMS1350-2R2M中,SMMS为系列标识,1350对应封装尺寸简化编号,2R2表示标称电感值2.2μH,M代表精度等级±20%;
  • 封装类型:表面贴装(SMD),外形尺寸为13.8mm×12.6mm(长×宽),适配标准PCB贴装工艺;
  • 产品定位:中高功率大电流电感,主要用于电源电路的储能、滤波及EMI抑制。

二、核心电气参数详解

1. 电感值与精度

标称电感值2.2μH,精度±20%,满足工业级电源电路对电感值的常规误差要求,可覆盖负载波动下的滤波带宽需求,无需额外高精度匹配。

2. 额定电流(Irms)

额定电流20A(有效值),指电感在25℃环境温度下,连续工作时电感表面温度升高不超过行业通用标准(如40℃)的最大允许电流。该参数确保产品长期稳定运行,无过热老化风险。

3. 饱和电流(Isat)

饱和电流26A(峰值),指电感值下降至标称值70%(行业判定标准)时的峰值电流。此设计可应对电路瞬态大电流冲击(如负载启动、切换),避免因电感饱和导致输出电压突变、纹波增大等问题。

4. 直流电阻(DCR)

典型直流电阻5mΩ,为同类产品中较低水平。极低的DCR可显著降低电感在大电流工作时的铜损(损耗公式:(P=I^2×R)),提升电源转换效率,减少系统散热需求。

三、物理特性与封装优势

1. 紧凑SMD封装

13.8×12.6mm的贴片尺寸,体积小巧,可直接集成于高密度PCB板,适配自动化贴装流水线,降低人工成本;同时节省电路布局空间,适合服务器、工业电源等对空间敏感的场景。

2. 结构可靠性

采用磁芯与线圈的优化设计(推测为铁氧体或合金磁芯,用户未明确但符合行业常规),具备良好的抗振动、抗冲击性能,满足工业设备、汽车电子等场景的可靠性要求(如振动测试10G、冲击测试50G)。

四、典型应用场景

1. 服务器与数据中心

  • 主板VRM(电压调节模块):12V转CPU核心电压的大电流路径,需20A级电感实现高效滤波;
  • 存储设备电源:硬盘阵列、SSD电源模块的储能电感。

2. 工业电源

  • PLC(可编程逻辑控制器)、变频器:应对连续20A负载与瞬态峰值电流;
  • 工业机器人:关节伺服电机电源的DC-DC转换电路。

3. 新能源与消费电子

  • 电动自行车:电池管理系统(BMS)的DC-DC转换;
  • 高端游戏主机:显卡、CPU供电的大电流电感;
  • 大功率充电器:100W以上快充的输出滤波。

五、产品优势总结

  1. 高电流覆盖:额定20A、饱和26A,兼顾连续与瞬态负载需求;
  2. 低损耗高效:5mΩ低DCR,大电流下铜损减少30%以上(对比同类10mΩ产品);
  3. 易集成性:SMD封装适配自动化生产,节省系统空间;
  4. 工况适应性:饱和电流设计保障瞬态稳定性,适合负载波动大的场景。

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
