SMMS1385-100MT 功率电感产品概述

SMMS1385-100MT是顺翔诺(SXN)推出的一款贴片式功率电感,针对大电流、低损耗场景优化设计,具备紧凑封装、高饱和电流等核心优势,广泛适用于电源系统、工业电子、汽车电子等领域。以下从多维度详细介绍该产品。

一、产品基本信息

项目 详情 品牌 顺翔诺(SXN) 型号 SMMS1385-100MT 产品类型 SMD贴片功率电感 封装尺寸 13.8mm(长)×12.8mm(宽)×8.80mm(高) 电感值标识 100MT对应10μH(±20%精度)

二、核心电性能参数

该电感的关键参数直接决定了其应用适配性,具体解读如下:

  1. 电感值与精度:10μH±20%——满足大多数电源电路的电感量需求,±20%精度在工业及消费电子场景下足够稳定,无需过高精度带来的成本冗余。
  2. 额定电流(Irms):15A——指25℃环境下,电感表面温升不超过30℃时的持续工作最大电流,确保长期运行无过热风险。
  3. 饱和电流(Isat):18A——当电流达到该值时,电感值下降约30%(行业通用标准),是极限电流阈值,可应对瞬时浪涌(如电路启动瞬间)。
  4. 直流电阻(DCR):12mΩ——绕组的直流电阻,直接影响功耗((P=I^2×DCR)),15A电流下仅产生2.7W损耗,发热控制优异。

三、产品设计特点

  1. 紧凑封装适配高密度布局:13.8×12.8×8.8mm的小体积设计,适合服务器、通信设备等空间紧张的场景,有效节省PCB面积。
  2. 低损耗低发热:12mΩ低DCR+高电流承载能力,减少自身功率损耗,降低系统散热要求,可简化散热设计(如无需额外加散热片)。
  3. 高抗浪涌能力:18A饱和电流远高于15A额定电流,具备电流冗余,可应对电路中的瞬时过流,提升整机可靠性。
  4. 自动化生产适配:SMD封装支持回流焊、贴片机自动化生产,批量生产效率高,降低人工成本。

四、典型应用场景

该电感的性能匹配以下高频场景:

  1. 大电流DC-DC转换器:服务器电源12V转5V/3.3V模块(输出10-15A)、车载快充(QC3.0/PD的大电流降压电路)。
  2. 工业电源模块:PLC、变频器等设备的电源单元,需长期稳定输出大电流,适配工业环境的宽温需求。
  3. LED驱动电源:户外显示屏、工矿灯等大功率LED阵列的驱动电路,单路输出可覆盖10-15A需求。
  4. 储能与滤波电路:UPS不间断电源的储能电感、通信设备的EMI滤波电路,利用电感特性抑制电磁干扰。

五、应用注意事项

  1. 焊接规范:回流焊峰值温度≤260℃,焊接时间≤10s;手工焊烙铁温度≤350℃,时间≤3s(避免损坏绕组)。
  2. 电流限制:持续工作电流≤15A,瞬时浪涌≤18A(防止电感值下降影响电路性能)。
  3. 环境要求:工作温度范围-40℃~125℃,避免高温高湿环境(如户外需做防护)。
  4. 安装要求:贴装时对齐焊盘,禁止施加过大压力(防止绕组变形)。

六、选型优势对比

与同类10μH功率电感相比:

  • 同尺寸下,额定电流(15A)比普通产品高30%;
  • DCR(12mΩ)比竞品低20%,发热更小;
  • 饱和电流(18A)具备更充足的浪涌冗余。

综上,SMMS1385-100MT是一款高性价比的功率电感,可替代部分进口产品,适合对电流、体积、损耗有严格要求的场景。

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
