PSPMAA0805-470M-ANP 产品概述
一、概述
PSPMAA0805-470M-ANP 为 PROD（谱罗德）出品的一款功率贴片电感，额定电流 3A，饱和电流（Isat）4.5A，标称电感值 47 μH（公差 ±20%）。封装为 SMD，外形尺寸约 8.5×8.0 mm，适用于对纹波抑制和能量存储有中等要求的开关电源与直流滤波场合。
二、主要参数
- 电感值：47 μH ±20%
- 额定电流：3 A
- 饱和电流（Isat）：4.5 A（定义为电感下降到初值一定比例时的电流）
- 直流电阻（DCR）：155 mΩ
- 封装：SMD，8.5×8 mm
- 品牌：PROD（谱罗德）
三、产品特点
- 体积与电流能力平衡：8.5×8mm 的 SMD 封装在有限面积内提供较高的饱和电流（4.5A），适合多种中功率场景。
- 稳定性与成本优势：47 μH ±20% 的容差适用于滤波与去耦等对精度要求不高但需要成本可控的设计。
- 中等 DCR：155 mΩ 表明在高直流偏置下会有一定能量损耗，应在热设计中予以考虑。
四、典型应用
- 降压/升压 DC-DC 转换器（中功率段）
- 电源输入/输出滤波、EMI 抑制
- 工业控制、通信终端、车载电子（视认证情况）
- 电池管理与便携电源模块
五、封装与焊接建议
采用回流焊工艺焊接，遵循无铅回流曲线。板上留有适当热沉与铜箔有利于散热，焊盘设计应参考供应商推荐尺寸以确保焊点可靠性。初次焊接后建议进行温升验证以评估在额定电流下的实际温度上升。
六、选型与使用建议
- 若工作电流接近或超过额定 3A，应考虑更大余量或选用低 DCR/更高 Isat 的型号；
- 关注直流电阻带来的功率损耗（P = I^2·DCR），并在热设计中留有裕量；
- 在高温或高纹波条件下，注意电感值随电流偏置的变化及温漂特性。
七、可靠性与认证
该系列适合工业级应用，常见为无铅 RoHS 合规。具体环境试验（温度循环、振动、潮湿）与寿命数据请参考厂方技术资料或样品测试报告。
八、采购信息
型号：PSPMAA0805-470M-ANP，品牌：PROD（谱罗德）。订购时请确认批次、库存与技术支持服务，必要时可索取样品进行上板测试与热工验证。若需要更高精度或更低 DCR 的替代型号，可与供应商沟通定制或推荐方案。

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.
