SMMS1350-100M 功率电感产品概述

SMMS1350-100M是顺翔诺(SXN)推出的一款贴片式功率电感,专为中功率直流转换及滤波场景设计,具备高电流承载能力、低损耗及小型化封装等特点,广泛适用于消费电子、车载、工业电源等领域。

一、产品基本信息

  • 产品类型:贴片功率电感
  • 品牌型号:顺翔诺(SXN)SMMS1350-100M
  • 核心标识:100代表电感值10μH,M代表精度±20%
  • 应用定位:中功率电路的储能、滤波与纹波抑制

二、核心电性能参数详解

1. 电感值与精度

SMMS1350-100M的标称电感值为10μH,精度±20%(实际范围8μH~12μH)。该精度满足绝大多数电源电路的设计需求,无需额外高精度补偿,可降低系统调试复杂度。

2. 电流承载能力

  • 额定电流(Idc):8A(直流连续电流),指电感在工作温度范围内持续承载的最大电流,此时电感值变化不超过30%,性能稳定;
  • 饱和电流(Isat):12A,指电感值下降至初始值70%时的极限电流。设计时需确保工作电流远低于饱和电流,避免电感饱和导致储能能力急剧下降、输出电压跌落。

3. 直流电阻(DCR)

产品DCR仅23mΩ,属于低阻设计。以额定电流8A为例,功率损耗为( P=I^2R=8^2×0.023=1.472W ),发热小,可有效提升电源转换效率,减少散热片等辅助设计成本。

4. 温度与频率特性

  • 工作温度范围:-40℃~125℃,适应车载、工业等极端环境;
  • 自谐振频率(SRF):约1.2MHz(典型值),在1MHz以下频率下电感性能稳定,适合低频至中频电源电路。

三、物理特性与封装规格

1. 封装尺寸

采用SMD贴片封装,具体尺寸为13.8mm(长)×12.6mm(宽)×5.0mm(高)(典型值),符合行业标准封装,便于PCB布局与自动化贴装。

2. 结构与材料

  • 磁芯:高性能铁粉芯,兼顾高磁导率与低损耗,适合大电流应用;
  • 绕组:多股漆包线绕制,减少趋肤效应影响,提升高频性能;
  • 包封材料:耐高温环氧树脂,具备抗振动、抗冲击、耐潮湿能力,符合RoHS环保标准;
  • 引脚:镀锡处理,焊接可靠性高,兼容无铅焊接。

四、典型应用场景

SMMS1350-100M的性能适配多种中功率电路:

  1. 开关电源(SMPS):DC-DC降压/升压转换器(如笔记本电脑、平板电源)的储能电感;
  2. 车载电子:车载充电器、LED大灯驱动、车载信息娱乐系统的电源滤波;
  3. 工业电源:PLC、变频器、伺服驱动器的辅助电源模块;
  4. 通信设备:路由器、基站电源的纹波抑制与EMI滤波;
  5. 消费电子:智能家居设备、游戏机的电源管理单元。

五、产品优势与价值

  1. 高电流余量:额定电流8A、饱和电流12A,设计余量充足,降低电流波动导致的失效风险;
  2. 低损耗高效:23mΩ低DCR减少发热,12V转5V/8A电源效率可达90%以上;
  3. 宽温可靠:-40℃~125℃工作范围,MTBF超10万小时,适应极端环境;
  4. 小型化布局:紧凑封装节省PCB空间,适合轻薄化产品设计;
  5. 成本效益:顺翔诺性价比优势,批量生产可降低整机BOM成本。

六、选型与使用注意事项

  1. 电流降额:85℃以上环境下,额定电流需降额30%~50%,避免过热;
  2. 电感值匹配:确认实际测量值(±20%范围内)是否满足电路要求;
  3. 焊接工艺:回流焊温度≤260℃(时间≤10s),避免磁芯或绕组损坏;
  4. 布局优化:电感靠近开关管与输出电容,减少回路面积,降低EMI干扰;
  5. 环保合规:符合RoHS、REACH标准,兼容无铅焊接,满足出口要求。

SMMS1350-100M凭借平衡的性能与成本优势,成为中功率电源电路的优选电感之一,可满足不同行业的可靠性与经济性需求。

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
