PSPMAA0503-150M-ANP 产品概述
一、产品简介
PSPMAA0503-150M-ANP（品牌：PROD/谱罗德）是一款面向功率滤波与能量储存的贴片功率电感。标称电感值为 15 µH，精度 ±20%，额定电流 2 A，饱和电流（Isat）3 A，直流电阻（DCR）192 mΩ。SMD 封装，外形尺寸为 5.4 × 5.2 mm，适合空间受限的中小功率电源应用。
二、主要电气特性
- 电感：15 µH ±20%（在无直流偏置测量条件下标称值）
- 额定电流：2 A（长期工作建议不超过此值以控制发热与电感衰减）
- 饱和电流：3 A（达到或接近此电流时电感量将显著下降）
- DCR：192 mΩ（影响导通损耗和效率）
- 封装尺寸：SMD，5.4 × 5.2 mm
基于 DCR，可估算铜损：在 2 A 时 P = I^2·DCR ≈ 0.768 W；在 3 A 时 P ≈ 1.728 W。实际功耗随环境温度与频率特性变化。
三、典型应用场景
- 开关电源（尤其为降压型 DC-DC 输出滤波）
- LED 驱动与驱动电流平滑
- 电池供电系统的能量传递与滤波
- 输入/输出 EMI 滤波器、瞬态抑制与噪声抑制场合
四、设计与选型建议
- 考虑直流偏置效应：电感在直流磁场下会下降，系统设计须校核带直流电流时的实际电感值。
- 留有裕量：建议工作电流在额定电流以下并与 Isat 保持足够距离（通常留 20–30% 余量）以避免磁饱和。
- 考虑 DCR 带来的功耗与热升：高 DCR 在高电流下会产生较多热量，应评估散热与整体效率。
- 容差 ±20%：对电感值敏感的滤波/谐振设计应按最差情形（-20%）检查频率响应与纹波抑制能力。
五、PCB 布局与焊接建议
- 将电感尽量靠近开关器件或负载放置，减小回路面积与寄生感抗。
- 输入/输出侧走线短且宽，降低额外 DCR 与寄生电感。
- 注意热路径，必要时在焊盘下或附近提供散热铜箔。
- 焊接按厂家推荐回流工艺，避免过高温度或超时引起元件性能退化（具体温度曲线请参照厂方资料）。
六、可靠性与检验建议
- 生产验证：建议测量电感值（含直流偏置）、DCR 与温升曲线以确认批次一致性。
- 应力与寿命：做热循环、湿热与振动试验以验证在目标应用下的可靠性。
- 如需在高温或高湿环境长期使用，应向供应商获取完整的环境规范与寿命数据。
七、封装与物料信息
- 物料型号：PSPMAA0503-150M-ANP
- 品牌：PROD（谱罗德）
- 封装：SMD，推荐在 PCB 布局前确认详细机械图和焊盘建议尺寸以保证可靠贴装与回流焊质量。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
