WPN252012ER47MT 产品概述

一、主要参数

  • 型号:WPN252012ER47MT(顺络 Sunlord)
  • 电感值:470 nH,公差 ±20%
  • 额定电流(Irms):4.1 A
  • 饱和电流(Isat):7 A
  • 直流电阻(DCR):约 26 mΩ
  • 封装:1008(小型表面贴装)

二、产品特点

  • 高电流承载:额定电流 4.1A,饱和电流达 7A,适合大电流开关电源与功率滤波场合。
  • 低直流电阻:DCR 约 26 mΩ,有利于降低 I²R 损耗,提高效率并减小温升。
  • 小型化封装:1008 SMD,适配高密度 PCB 布局与自动化贴装。
  • 常用规格:470nH ±20% 适用于中低阻抗、需较大能量存储与滤波的设计。

三、典型应用

  • 同步降压/升压 DC-DC 转换器输出滤波或能量存储元件;
  • 电源管理模块(PMIC)、GPU/CPU 周边电源滤波;
  • 输入/输出电源去耦与纹波抑制;
  • 汽车电子、通信设备及工业电源中的电流滤波与能量缓冲。

四、选型与使用注意事项

  • 电流裕量:设计时建议保持工作峰值电流低于 Isat 的 60–80%,以避免明显的电感量下降和磁饱和。
  • 发热与功耗:按实际通过电流计算铜损 P = I² × DCR,评估温升并留足散热空间。
  • 直流偏置效应:在直流偏置下电感值会下降,需在目标工作电流条件下验证实际电感特性。
  • 布局建议:走线尽量短且截面积大,进出线孔(vias)数量适当,避免靠近热源或强干扰源。
  • 环境与可靠性:留意工作温度对 DCR 与电感值的影响,满足系统长期可靠性要求。

五、封装与安装

  • 1008 封装适合自动化贴片(SMT)生产,通常采用卷带(Tape & Reel)包装便于贴装。
  • 推荐按厂方提供的 PCB 阵列与回流焊工艺资料进行贴装与回流,避免过冲和长期高温暴露导致磁芯性能退化。

六、典型电路建议

  • 在降压转换器中作为输出电感时,依据开关频率、输入/输出电压与允许纹波电流计算所需 L 值与电流容限;若 ripple 电流较大,应评估电感在该电流下的电感衰减与损耗,并考虑并联或升容的方案。

七、订购与技术支持

  • 型号:WPN252012ER47MT,品牌:Sunlord(顺络)。
  • 选型时如需更详细的电感-电流特性曲线、频率响应、温升曲线或封装尺寸图纸,请向顺络官方或授权分销商索取产品规格书(Datasheet)与样品,以便在实际工况下验证并完成可靠性评估。

产品定位为面向中高电流、要求低损耗与小型化布局的功率电感,适合用于各类开关电源与功率滤波场景,选型时以实际工作电流、纹波需求与热管理为主导。

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
