顺络SWPA5020S680MT功率电感产品概述

一、产品基本定位

顺络SWPA5020S680MT是一款小型化表面贴装(SMD)功率电感,属于顺络经典5020系列(封装尺寸5.0×5.0×2.0mm),核心针对中小电流、紧凑空间的电源电路设计,可满足便携式电子、物联网终端等低功耗场景的储能、滤波需求,是电源管理模块(PMIC)中DC-DC降压/升压电路的常用元件。

二、关键电气参数详解

该电感参数精准匹配低功耗应用,各参数意义及应用参考如下:

  1. 电感值与精度:标称68μH,精度±20%。此精度满足大多数电源滤波、储能需求(无需极高精度的场合),可避免因精度过高带来的成本增加;
  2. 额定电流(Irms):640mA。这是电感持续工作的最大允许电流(线圈温升不超过行业标准限值),应用电路的持续负载电流需低于该值,否则会导致电感过热、性能下降;
  3. 饱和电流(Isat):650mA。指电感值下降至初始值30%时的电流(行业通用判断标准),是峰值电流的上限——若电路峰值电流超过650mA,电感储能能力会显著降低,可能引发电源纹波增大、输出不稳定;
  4. 直流电阻(DCR):962mΩ。该值为电感线圈的直流电阻,直接影响功耗:小电流下(<600mA),线圈损耗(I²×R)可忽略(约0.35mW),能保证电源转换效率;

三、封装与物理特性

  • 封装形式:表面贴装(SMD),支持自动化贴装(SMT),适配常规回流焊工艺;
  • 尺寸规格:5.0×5.0×2.0mm(长×宽×高),属于小尺寸功率电感,可大幅节省PCB空间,适合智能手表、蓝牙耳机等微型设备的高密度布局;
  • 环保认证:符合RoHS 2.0、REACH等国际环保标准,无铅无卤,满足电子产品出口要求。

四、典型应用场景

该电感因小尺寸、中小电流的特性,广泛应用于以下场景:

  1. 便携式消费电子:智能手机、智能手表、蓝牙耳机的PMIC降压电路(如5V转3.3V/1.8V);
  2. 物联网(IoT)终端:传感器节点(如温湿度传感器、运动传感器)、低功耗网关的电源滤波与储能;
  3. 小型工业控制:微型PLC、远程监控模块的稳压电路;
  4. 车载低功耗模块:汽车仪表盘背光、胎压监测系统(TPMS)的辅助电源。

五、品牌与可靠性背书

顺络(Sunlord)是国内被动元件领域龙头企业,专注电感研发生产20余年,产品通过ISO 9001、IATF 16949等认证,SWPA5020S680MT经过以下可靠性测试:

  • 高低温循环(-40℃~+85℃,1000次);
  • 振动测试(10~2000Hz,加速度2g);
  • 湿度测试(85℃/85%RH,500h); 可靠性符合工业级与消费级产品要求,适合量产应用。

六、选型注意事项

  1. 电流匹配:持续负载电流≤640mA,峰值电流≤650mA;
  2. 空间确认:PCB布局需预留5.0×5.0mm的贴装空间(含焊盘);
  3. 精度需求:若需±10%精度,需切换至顺络其他高精度系列(如SWPA5020S680HT);
  4. 频率适配:该电感适合开关频率500kHz~2MHz的DC-DC电路(常规电源管理芯片的开关频率范围),若频率过高需考虑交流电阻(ACR)影响。

该产品以“小尺寸+中小电流”为核心优势,覆盖了多数低功耗电子设备的电源设计需求,是顺络在紧凑型功率电感领域的成熟产品。

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
