PSPHAQ127-150M 产品概述

一、产品简介

PSPHAQ127-150M 是谱罗德(PROD)推出的一款功率电感,额定电流与饱和电流均为 5.1A,电感量为 15 μH,公差 ±20%。该器件采用 SMD 封装,外形尺寸 12×12 mm,专为开关电源和高电流滤波场景设计,旨在在有限体积内提供较低直流电阻和良好的储能性能,提升系统效率与电源稳定性。

二、主要参数

  • 型号:PSPHAQ127-150M
  • 品牌:PROD(谱罗德)
  • 电感值:15 μH,公差 ±20%
  • 额定电流(Irated):5.1 A(连续)
  • 饱和电流(Isat):5.1 A(定义为电感降额至指定比例时的电流)
  • 直流电阻(DCR):27 mΩ
  • 封装形式:SMD,外形 12 × 12 mm

三、性能特点与优势

  1. 高频开关兼容:适用于中低频率开关电源的储能与滤波,能在典型开关频率下稳定工作。
  2. 低 DCR 损耗小:27 mΩ 的直流电阻在同类尺寸功率电感中属于较低水平,有助于降低铜损、提高转换效率,尤其在 5A 量级电流下能显著减少发热。
  3. 饱和电流与额定电流一致:Isat 与 Irated 同为 5.1A,说明在该电流范围内电感量保持相对稳定,便于设计时按额定电流直接评估性能边界。
  4. SMD 贴片封装:12×12mm 的表面贴装设计,适合自动化生产,利于高密度布板和体积受限的电源模块集成。
  5. 可靠性考虑:谱罗德作为供应商,其功率电感通常经过温升与寿命测试,适合工业及商用级电源设计(具体可靠性数据请参照厂方规格书)。

四、典型应用场景

  • DC-DC 降压/升压转换器的能量储存元件(尤其是输出滤波)
  • 输入滤波与去耦,抑制开关器件造成的干扰
  • 电源管理模块与点对点供电系统
  • 汽车电子、工业电源和通信设备等需要 5A 级电流处理的场合

五、封装与可靠性要点

PSPHAQ127-150M 为 SMD 贴片元件,12×12 mm 的尺寸在散热与安装强度上有良好平衡。使用时建议:

  • 参考厂家推荐的焊盘布局与回流焊工艺,以保证焊接可靠性与电气性能。
  • 在高功率应用下注意 PCB 散热设计:加大铜皮、使用热过孔或散热垫以降低结温,减小 DCR 因温升而增加的损耗。
  • 考虑电感器件的磁屏蔽与磁耦合问题,合理安排器件间距与方向,避免相互影响。

六、选型建议与使用注意

  • 电流裕量:尽量留有裕量,若系统存在较大纹波电流或短时冲峰,建议选择额定电流或 Isat 明显高于实际峰值的器件。
  • 纹波电流影响:设计时评估交流纹波电流产生的附加损耗及温升,必要时使用热仿真或实际测量验证。
  • 电感公差:±20% 的电感公差在精密滤波或谐振应用中需考虑其对工作频率和环路性质的影响。
  • 饱和特性:虽然 Isat = 5.1A,但饱和并非瞬时失效,而是电感值下降,系统须保证在饱和区域仍能稳定工作或加保护措施。
  • 兼容性检查:在最终设计中,建议结合电路的具体开关频率、输出纹波、电源拓扑与工作温度,参考厂方完整规格书的频率响应、温升曲线及寿命数据完成最终确认。

总结:PSPHAQ127-150M 是一款适合 5A 级功率处理的通用型 SMD 功率电感,凭借 15 μH 的储能能力、较低的 DCR(27 mΩ)和紧凑 12×12 mm 封装,适用于多种开关电源和电源滤波应用。在设计使用中应关注纹波电流、温升与饱和裕量,以确保长期稳定可靠运行。若需更详细的频率特性、热性能或封装标准,请参阅谱罗德官方规格书或联系供应商获取样品与测试数据。

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.
