PSPMAC1045H-101M-ANP — 产品概述

一、基本参数与型号简介

PSPMAC1045H-101M-ANP(品牌:PROD / 谱罗德)是一款表面贴装功率电感,标称电感值为100 µH,公差±20%。器件为SMD封装,外形尺寸约11 × 10 mm,面向电源滤波与储能应用。关键电气参数:额定电流(Ir)2 A,饱和电流(Isat)4 A,直流电阻(DCR)约300 mΩ。

二、主要特性

  • 电感值:100 µH(±20%),满足一般电源滤波与能量储存需求。
  • 电流能力:额定持续电流2 A,饱和电流4 A,提供较大的磁通裕量以应对瞬时峰值。
  • 低频到中频性能适用于降压转换器输出滤波、输入滤波及EMI抑制。
  • DCR = 300 mΩ,说明在额定电流下存在明显的铜损与温升,需要在热预算中考虑功耗影响。

三、典型应用

  • DC–DC 降压转换器(输出侧滤波与能量储存)
  • 电源输入滤波与去耦,抑制共模/差模噪声(视电路拓扑而定)
  • 工业、通信和消费类设备的中低频开关电源模块
  • 需要较大电感量且对体积有一定限制的应用场景

四、选型与设计注意事项

  • 电流与温升:按公式 P_loss = I^2 × DCR 估算功耗。例:在额定电流2 A时,P_loss ≈ 1.2 W,需评估封装和PCB散热是否能接受该损耗,必要时应选用更低DCR或并联方案。
  • 饱和裕度:Isat = 4 A 表示在此电流附近电感会显著下降。设计时应保证工作峰值电流低于Isat,常用做法是将峰值控制在Isat的70–90%以内以防止性能退化。
  • 电感公差:±20% 意味着实际电感在80–120 µH之间波动,关键滤波/谐振电路需评估容差对性能的影响。
  • 高频特性:该类功率电感在高频时会出现自谐振和损耗增加,选择时应结合器件频率响应和工作开关频率评估。

五、封装与安装建议

  • 封装尺寸11×10 mm,SMD 贴装。推荐遵循供应商推荐的焊盘尺寸与回流工艺参数,保证焊点可靠性。
  • 焊接:采用无铅回流焊,焊前检查焊膏印刷及贴装精度,必要时在大尺寸电感下使用点胶固定以防贴装过程中移位。
  • PCB布局:电感应靠近负载或滤波点放置,输入电容与电感形成回路路径应尽可能短且回路面积小,以减少寄生电感与辐射。

六、测试与可靠性验证

  • 建议在最终电路中测量实装后的直流电阻与电感值、温升及在工作频率下的AC损耗。
  • 做热循环、机械跌落与焊接可靠性测试以验证在实际应用环境下的长期稳定性。
  • 如对噪声、纹波电流或效率有严格要求,应在目标负载与开关频率下做完整的系统级评估。

总结:PSPMAC1045H-101M-ANP 是一款针对中等功率、需要较大电感量的SMD功率电感。其较高的DCR带来明显损耗,设计时应注意热管理与电流裕度;在合适的应用场景中可提供可靠的滤波与储能功能。欲获取更详细的机械图、焊盘建议及温度规范,请参考厂方完整数据手册或向供应商索取样品测试。

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.
