SWPA5040S6R8MT 产品概述

一 概述

SWPA5040S6R8MT 是顺络(Sunlord)推出的一款贴片功率电感,标称电感值 6.8 µH,容差 ±20%,适用于各类开关电源和电源管理模块。器件采用紧凑 SMD 封装(5 × 5 mm),提供较高的额定电流和良好的抗磁饱和特性,适合中小功率 DC–DC 转换器或滤波电路使用。

二 主要参数

  • 电感值:6.8 µH(±20%,范围≈5.44 µH ~ 8.16 µH)
  • 额定电流(Irated):2.5 A(连续工作)
  • 饱和电流(Isat):2.9 A(超过该电流电感量将明显下降)
  • 直流电阻(DCR):约 56 mΩ
  • 封装:SMD,5 × 5 mm
  • 品牌:Sunlord(顺络)
    产品型号:SWPA5040S6R8MT

三 主要特性

  • 紧凑体积、适配 SMD 自动贴片与回流焊工艺,便于高密度 PCB 设计。
  • 较高的额定电流与饱和电流,适合较大纹波电流场合。
  • 低 DCR 降低铜损,提高转换效率;注意 DCR 导致的功耗与温升。
  • ±20% 容差适用于一般功率滤波与储能应用,需在设计中考虑容差影响。

四 典型应用

  • 同步/非同步降压 (Buck) 转换器与升压 (Boost) 模块。
  • 模块化电源、点对点供电、负载开关滤波。
  • 输入/输出滤波器、功率整流与能量储存单元。
  • 工业控制、通信设备与消费类电子的电源前端。

五 使用建议与 PCB 布局要点

  • 将电感尽量靠近开关管与整流二极管或 MOSFET,缩短电感—开关—电容回路路径以降低辐射与寄生。
  • 输入/输出电容与电感之间走短、粗的铜箔,必要时使用多通孔(via)分担电流。
  • 为降低温升,避免电感下方大面积无铜区,必要时在下层布置散热铜箔或热通孔。
  • 在高纹波或脉冲电流场合,尽量保证连续工作电流低于额定电流,以延长寿命并控制温升;峰值电流不应超过 Isat。

六 热与损耗计算提示

  • 由于 DCR 存在,功耗 P ≈ I^2 × DCR。若连续电流为 2.5 A,则 P ≈ 2.5^2 × 0.056 ≈ 0.35 W(约值),需评估 PCB 散热能力与周围元件耐温性。
  • 在实际选型时建议保留裕量(例如按额定电流的 70–90% 运行),并结合实际温升测试确认可靠性。

七 封装与订购信息

  • 尺寸优势适用于自动化贴装与回流焊流程,常见包装方式为带卷(Tape & Reel)。
  • 订购时请使用完整型号 SWPA5040S6R8MT,并向供应商索取最新尺寸图与回流焊曲线,以便确认高度和装配要求。

八 小结

SWPA5040S6R8MT 以 5×5 mm 的紧凑封装在中小功率电源领域提供了 6.8 µH 电感、2.5 A 连续电流与 2.9 A 饱和电流的平衡性能。设计时需关注 DCR 导致的损耗与温升,并通过合理 PCB 布局和裕量设计保证长期稳定运行。如需更详细的电感随电流、频率特性曲线或封装尺寸与回流规范,请参照顺络官方数据表或联系供应商获取完整规格书。

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
