SMMS0650A-680M 一体成型电感产品概述

一、产品基本属性与定位

SMMS0650A-680M是顺翔诺(SXN)推出的车规级一体成型电感,采用表面贴装(SMD)封装,尺寸为7.1×6.6mm(长×宽),符合汽车电子行业AEC-Q200可靠性标准。产品聚焦车载电子、工业控制等对可靠性要求严苛的小型化电路场景,兼顾高集成度与电气性能稳定性,是替代传统绕线电感的高性价比方案。

二、核心电气性能参数

该电感的关键参数明确,为电路设计提供精准参考:

  • 电感值:68μH,精度±20%,满足中等功率电源转换的电感量需求(适配100kHz-1MHz开关频率);
  • 额定电流(Irms):1.7A,指环境温度25℃时,电感温升不超过40K的最大连续工作电流,是长期可靠运行的核心指标;
  • 饱和电流(Isat):2.2A,指电感值下降30%时的电流阈值,设计需留足余量(建议≤1.8A)以避免性能衰减;
  • 直流电阻(DCR):442mΩ,低电阻设计可降低功率损耗(1.7A下功耗约1.27W),提升电路效率。

三、封装与结构特点

作为一体成型电感,SMMS0650A-680M具有显著结构优势:

  • 一体成型工艺:磁芯与线圈通过模压固化为整体,无间隙松动,可耐受汽车级振动(10-2000Hz)与冲击(1000m/s²),可靠性远高于传统绕线电感;
  • 小封装高密度:7.1×6.6mm的紧凑尺寸适配车载PCB的小型化设计,同时保持足够的电感量与电流承载能力;
  • 低EMI特性:封闭磁路结构减少电磁辐射泄漏,降低对周边敏感电路(如ADAS传感器)的干扰,符合汽车电子EMC要求。

四、车规级可靠性保障

AEC-Q200认证是该电感的核心竞争力,意味着其通过了汽车电子行业的严苛测试:

  • 环境测试:-40℃至125℃宽温循环、高湿存储(85℃/85%RH);
  • 寿命测试:155℃高温老化、加速寿命评估(满足汽车10年/15万公里生命周期);
  • 机械测试:振动、冲击、跌落测试,确保在车载颠簸、碰撞场景下性能稳定。

五、典型应用场景

结合参数与车规特性,该电感适用于以下场景:

  1. 车载电源系统:DC-DC降压转换器(12V转5V/3.3V)、车载充电模块;
  2. ADAS与传感器供电:毫米波雷达、摄像头、超声波传感器的稳压电路;
  3. 车载照明:LED日间行车灯、氛围灯的驱动电路;
  4. 小型电机驱动:车载座椅调节、后视镜折叠电机的控制电路;
  5. 工业控制:小型PLC、伺服驱动器的辅助电源。

六、应用选型注意事项

为确保电路稳定运行,需注意以下要点:

  • 电流余量:实际工作电流需低于额定电流1.7A,饱和电流留20%以上余量(避免超过2.2A);
  • 功耗控制:DCR导致的功耗需纳入PCB散热设计(如增加散热铜箔);
  • 频率匹配:适用于100kHz-1MHz开关频率,超高频会导致电感值下降;
  • 焊接规范:贴片焊接温度需控制在260℃/10s以内,避免损坏磁芯。

SMMS0650A-680M凭借车规可靠性、小封装高密度与低EMI特性,成为车载电子小型化设计的优选电感之一。

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
