PSPMAA063T-150M-ANP 产品概述

一、产品简介

PSPMAA063T-150M-ANP 是谱罗德(PROD)推出的一款表面贴装功率电感,具有紧凑封装与较高电流承载能力,适用于中小功率开关电源与电源滤波场合。器件以稳定的感值和可接受的直流电阻在功率管理电路中提供磁能储存与纹波滤除功能,是进行功率变换和输出滤波的常用器件之一。

二、主要参数与性能

  • 电感值:15 μH
  • 精度:±20%
  • 额定电流(Irated):3.0 A(连续工作时建议不超过此值以控制温升)
  • 饱和电流(Isat):3.5 A(接近电感开始明显降额的电流)
  • 直流电阻(DCR):135 mΩ(影响导通损耗与系统效率)
  • 封装形式:SMD,尺寸 7.1 × 6.6 mm
  • 品牌:PROD(谱罗德)
  • 型号:PSPMAA063T-150M-ANP

器件特点:

  • 中等电感值与中高电流承载能力的组合,适配常见的降压/升压转换器设计;
  • SMD 封装便于自动化贴装与量产应用;
  • 较低的 DCR 在 3A 级别中有助于降低功率损耗,但在高效率设计中仍需评估整体损耗预算。

三、典型应用场景

  • 3A 级别单片降压(Buck)转换器输出滤波;
  • 升压(Boost)或 SEPIC 等拓扑中的能量存储/传输元件;
  • DC-DC 模块、笔记本电源子电源、车载辅助电源和嵌入式系统电源;
  • 输入/输出电源滤波、纹波抑制及电磁干扰(EMI)抑制的初级级联元件。

四、选型要点与使用建议

  1. 电流留量
    • 额定电流为 3A,饱和电流为 3.5A,Isat 与 Irated 相差有限。若电路存在较大峰值电流或冲击电流,应选用额定和饱和裕量更高的型号或加以电流限制,避免工作点进入饱和区导致电感骤降与电路失稳。
  2. DCR 与效率权衡
    • 135 mΩ 的 DCR 在 3A 工作条件下会产生显著的 I^2R 损耗(例如在 3A 下约 1.22W),设计时需评估允许的温升与整体效率,必要时考虑并行或更低 DCR 的替代器件。
  3. 频率与核心损耗
    • 本类功率电感通常适用于几十 kHz 到几百 kHz 的开关频率。高频下核心损耗与绕组损耗会增加,应结合实际频率、纹波电流和温度特性做损耗估算。
  4. 温升与散热
    • 在实际电路中,注意器件周边散热和 PCB 铜箔面积,增大接地/散热铜面积、减少串联电阻可降低温升。
  5. 布局建议
    • 电感应靠近开关器件或输出端放置,输入与输出走短宽导线,减少环路面积;避免在高磁场敏感元件附近放置。

五、封装与焊接注意事项

  • PSPMAA063T-150M-ANP 为 SMD 封装(7.1×6.6 mm),适合自动贴片与回流焊工艺。建议按无铅回流焊规范(IPC/JEDEC 指南)进行焊接,使用合适的回流曲线并避免重复高温循环以防影响磁芯与粘结材料性能。
  • 贴片时注意基板焊盘尺寸与贴装方向,使用推荐的 PCB land pattern 可确保焊点可靠性与机械强度。
  • 装配后避免对电感施加过大机械应力(弯曲、挤压),以免引起磁芯开裂或连接失效。

六、可靠性与测试建议

  • 在设计验证阶段,应进行温升测试、直流电阻测量、感值随偏置电流的变化测试以及纹波电流下的损耗测试,确认在目标工作点下的性能满足系统需求。
  • 建议做瞬态电流冲击与振动/冲击可靠性测试,尤其在车载或工业应用中,以验证焊接与结构可靠性。

七、常见问题与采购信息

  • 若电路存在频繁大电流峰值,建议选用 Isat 与 Irated 有更大裕量的电感或提高散热/并联方案;
  • 采购时可向供应商确认器件的供货包装(通常为卷带 Tape & Reel)、批次测试报告以及在高温或高频条件下的特性曲线;
  • 产品型号:PSPMAA063T-150M-ANP,品牌:PROD(谱罗德)。如需进一步的频率特性曲线、温升数据或样品验证,可联系厂家或正规代理获取详细规格书与样品测试支持。

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.
