PSPMAA0402-1R0M-ANP 产品概述
一、产品简介
PSPMAA0402-1R0M-ANP 是谱罗德（PROD）推出的一款表面贴装功率电感，封装尺寸为 4.5×4.1 mm。该器件在紧凑体积下提供 1.0 μH 的电感值与良好的大电流处理能力，适合要求高效率与小型化的开关电源和电源管理应用。
二、主要参数
- 电感值：1.0 μH，公差 ±20%
- 额定电流（Irms）：4.5 A
- 饱和电流（Isat）：7 A（在规定电流下电感降至指定比例时）
- 直流电阻（DCR）：约 27 mΩ
- 封装形式：SMD，尺寸 4.5 × 4.1 mm
这些参数表明器件在中高电流场合具有较低损耗和良好的抗饱和能力。
三、产品特点
- 大电流承载能力：额定 4.5 A，饱和点 7 A，可满足中高功率密度转换器的需求。
- 低直流电阻：约 27 mΩ，减小铜损与温升，提高系统效率。
- 紧凑结构：小尺寸便于高密度 PCB 布局与自动化贴装。
- 电磁兼容性与稳定性：设计优化以减少漏磁与寄生参数，对频繁开关工作点表现稳定。
四、典型应用场景
- 同步降压（Buck）转换器输出滤波与能量存储。
- 电源管理模块、点对点供电、VRM 前端滤波。
- 工业控制、通信设备、服务器与消费类电子的开关电源子系统。
- 需要在受限空间中实现高电流滤波与稳压的场合。
五、布局与焊接建议
- 缩短输入输出回路的回路面积，降低寄生电感和电磁干扰（EMI）。
- 推荐在电感两端采用宽铜箔焊盘并与散热平面良好连接，以利热量散发。
- 回流焊遵循厂商给定的温度曲线，避免超出峰值温度引起性能退化或机械损伤。
- 如需并联以提升电流能力，确保各分支对称布局并匹配阻抗。
六、可靠性与测试建议
- 在设计验证阶段进行温升测量、热循环、振动与长时间寿命测试，确认在实际工作条件下的电气与机械稳定性。
- 对于高温或连续高电流工况，建议留有安全裕量或选择更高额定电流的型号以提高可靠性。
- 建议关注频率响应与饱和特性，以避免工作点进入线圈饱和区影响系统稳定性。
七、采购与包装信息
- 品牌：PROD（谱罗德）；型号：PSPMAA0402-1R0M-ANP。
- 常见为标准 SMD 卷带包装，适配自动化贴装生产线。
- 具体样品、最小起订量、价格和交期等请联系谱罗德经销商或官方销售渠道获取。

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.
