PSPMAA1265H-4R7M-ANF 产品概述

一、产品简介

PSPMAA1265H-4R7M-ANF 是谱罗德(PROD)推出的一款一体成型功率电感,额定电感值为 4.7 μH(公差 ±20%)。该器件为表面贴装(SMD)封装,尺寸 13.2 × 12.8 mm,专为大电流电源路径设计,适用于开关电源和电源管理模块中的滤波与储能应用。

二、主要参数

  • 电感值:4.7 μH ±20%
  • 额定电流(Ir):14 A
  • 饱和电流(Isat):25 A(常规定义为电感下降到初始值一定比例时的电流)
  • 直流电阻(DCR):约 8 mΩ
  • 类型:一体成型功率电感(Molded SMD)
  • 封装尺寸:13.2 × 12.8 mm
  • 品牌:PROD(谱罗德)

三、产品特点与优势

  • 低 DCR:约 8 mΩ 的低直流电阻可有效降低 conduction 损耗,提高转换效率,适合高效率要求的电源设计。
  • 大电流能力:14 A 的额定电流与 25 A 的饱和电流保证在大电流、强纹波场景下仍能保持稳定电感值。
  • 一体成型封装:机械强度高,抗振动、耐焊接工艺,便于自动贴装和回流焊接。
  • 紧凑尺寸:13.2 × 12.8 mm 的 SMD 外形在同等电流等级下节省 PCB 面积,适用于中高功率密度的电源模块。
  • 稳定性好:针对功率应用优化的磁芯和绕组结构,保证在温升和磁通变化下的可靠性。

四、典型应用场景

  • 同步/非同步降压转换器(Buck converters)
  • DC-DC 电源模块与输出滤波
  • 汽车电子电源(在满足相应认证和温度等级下)
  • LED 驱动电源、高功率驱动模块
  • 电池管理系统(BMS)和便携式电源/充电器
  • 工业电源及伺服驱动前端滤波

五、设计与布局建议

  • 放置位置:建议将电感尽量靠近开关管与输出电容,减少开关回路的环路面积以降低 EMI。
  • 散热处理:高电流工作时会产生热量,建议在电感下方及周围采用多过孔(via)连通散热层或在 PCB 引线处做铜腹加厚以利散热。
  • 饱和裕量:系统设计时应为峰值电流与纹波电流预留裕量,避免接近 Isat,保证电感值稳定。
  • 焊接建议:遵循制造商回流焊温度曲线,避免长时间高温;回流后建议检查焊点可靠性。
  • 布线注意:输入与输出电容器应靠近电感与开关器件,减小寄生电感与电阻带来的性能损失。

六、使用注意事项

  • 电流容限:若长期在接近或超过额定电流 14 A 工作,会导致温升与磁芯损耗增加,应考虑降额使用或选择更大规格型号。
  • 饱和与非线性:在瞬态大电流冲击下可能出现磁芯部分饱和,设计时应考虑短时脉冲电流的影响。
  • 环境与可靠性:工作环境温度、湿度及振动会影响寿命与性能,若用于汽车或工业级应用,请确认对应的环境规范与验证要求。
  • 测试与验证:建议在目标电路中做热成像与效率测试,评估在实际纹波与负载条件下的电感升温与性能表现。

七、采购与封装信息

  • 型号:PSPMAA1265H-4R7M-ANF
  • 品牌:PROD(谱罗德)
  • 封装形式:SMD(13.2 × 12.8 mm)
  • 建议在工程选型阶段索取样品并参考厂商提供的完整数据手册(包含电感随频率变化曲线、温升测试、回流焊曲线与可靠性数据)以完成最终验证。

如需在特定系统(例如某型号降压转换器或汽车 12V/48V 总线)中替换或对比该型号与其他电感,请提供工作电流、最大纹波、允许温升与目标效率,我可以给出更具体的匹配与选型建议。

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
