SMMS1385-6R8MT功率电感产品概述

顺翔诺(SXN)推出的SMMS1385-6R8MT是一款针对大功率场景设计的SMD贴片功率电感,凭借高电流承载能力、低损耗特性,广泛适配开关电源、车载电子等领域的电路需求。以下是产品的详细概述:

一、产品基本信息

SMMS1385-6R8MT属于顺翔诺功率电感系列,型号命名遵循行业常规逻辑:SMMS为系列标识(贴片功率电感),1385对应封装尺寸代码,6R8表示标称电感值6.8μH,MT为封装/工艺补充标识。产品采用无铅SMD贴片封装,符合RoHS环保标准,支持自动化贴装与回流焊接,可直接集成至各类PCB电路中。

二、核心电气参数解析

产品的关键电气参数决定了其应用场景与性能表现,具体如下:

  1. 电感值与精度:标称电感值6.8μH,精度±20%,满足大多数功率电路对电感值的偏差要求,无需额外高精度筛选;
  2. 额定电流(Irms):16A(有效值),指持续工作时允许的最大电流(交流/直流均可),在此电流下电感温度上升控制在行业常规范围(一般≤40℃);
  3. 饱和电流(Isat):20A,是电感值下降至标称值80%时的临界电流,该参数高于额定电流,为电路过载或瞬态电流提供安全余量,避免电感性能恶化;
  4. 直流电阻(DCR):10mΩ,反映电感绕组的铜损,低DCR可显著降低功率损耗、减少发热,提升电源转换效率(尤其在大电流场景下优势明显)。

三、物理特性与封装设计

SMMS1385-6R8MT采用紧凑SMD贴片封装,具体尺寸为13.8mm(长)×12.8mm(宽)×8.80mm(高),属于中小体积功率电感,适配常规PCB布局空间。封装设计具备以下特点:

  • 引脚间距符合行业标准,可兼容主流贴片机的自动化生产;
  • 磁芯结构优化(推测为铁氧体/合金复合磁芯,符合功率电感常规设计),兼顾电感值稳定性与电流承载能力;
  • 表面镀层采用无铅工艺,符合欧盟RoHS指令,无有害物质排放。

四、主要应用领域

凭借高电流、低损耗的核心优势,SMMS1385-6R8MT可覆盖以下典型场景:

  1. 开关电源:AC/DC变换器、DC/DC降压/升压模块(如24V转12V、10A以上的电源电路);
  2. 车载电子:车载充电器、电机驱动(如电动座椅、车窗电机控制)、车载电源管理单元(PMU);
  3. 工业控制:伺服系统、变频器、工业电源(如PLC供电模块);
  4. 通信设备:基站电源、服务器电源、光模块供电电路;
  5. 消费电子:大功率快充充电器(如65W以上PD充电器)、LED大功率驱动电源。

五、产品优势与特点

与同类功率电感相比,SMMS1385-6R8MT具备以下核心优势:

  1. 高电流余量:额定电流16A、饱和电流20A,满足大功率场景的持续与瞬态电流需求,避免过载损坏;
  2. 低损耗设计:10mΩ低DCR大幅降低铜损,减少发热,提升电源效率(可降低电源模块的散热成本);
  3. 性能稳定可靠:在额定电流范围内电感值波动小,饱和电流阈值明确,可保障电路长期稳定运行;
  4. 集成度高:紧凑贴片封装节省PCB空间,适配高密度电路设计;
  5. 环保合规:无铅工艺符合RoHS标准,满足出口与高端产品的环保要求。

六、选型与使用注意事项

  1. 电流选型:电路最大工作电流需小于额定电流16A,且瞬态电流需低于饱和电流20A,避免电感饱和导致性能下降;
  2. 电感值偏差:±20%的精度需在电路设计中考虑(如搭配滤波电容优化纹波);
  3. 焊接要求:采用回流焊工艺时,需遵循常规贴片电感的温度曲线(一般峰值温度230-250℃,时间≤30s);
  4. 散热考虑:大电流工作时需保证PCB布局的散热路径(如增加铜箔面积),避免局部过热。

综上,SMMS1385-6R8MT是一款高性价比的大电流贴片功率电感,可满足多领域大功率电路的需求,是电源设计工程师的实用选型之一。

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
