PSPMAA0803H-220M-ANP 产品概述
一、产品简介
PSPMAA0803H-220M-ANP 是谱罗德（PROD）推出的一款功率型贴片电感，标称电感量 22µH、精度 ±20%，面向中大电流开关电源与滤波电路。器件为 SMD 封装，外形尺寸 8.0×8.5×3.0 mm，低外形高度便于板级组装与有限空间内的电源模块设计。
二、主要参数
- 电感值：22 µH（±20%）
- 额定电流（Irms）：3 A（连续）
- 饱和电流（Isat）：5 A（磁芯起饱和、感值急降的近似界限）
- 直流电阻（DCR）：130 mΩ
- 封装：SMD，尺寸 8.0×8.5×3.0 mm
- 品牌：PROD（谱罗德）
- 型号：PSPMAA0803H-220M-ANP
三、产品特点
- 适配中功率场合：3A 连续电流能力与 5A 的峰值饱和电流，适合降压转换器的输出电感或输入滤波器使用。
- 紧凑封装：8.0×8.5×3.0 mm 的占板面积与低高度，便于模块化和高密度 PCB 布局。
- 可控功耗：DCR 为 130 mΩ，在满足电感要求的同时需注意铜损与温升管理。
四、典型应用
- DC–DC 降压转换器（输出滤波/储能电感）
- 输入滤波和EMI 抑制电路
- LED 驱动与电源管理模块
- 工业与消费类电源模块、通信设备及车载低压电源（需按车规要求验证）
五、设计与使用注意事项
- 电流热损耗估算：在额定 3 A 时，铜损约为 I^2·DCR = 3^2×0.13 ≈ 1.17 W，器件会明显发热。请在布局时留出散热空间并评估温升对电感值与绝缘的影响。
- 饱和处理：Isat=5A 表明短时冲击或脉冲电流可达此值，但长期超过额定电流会造成电感值下降与过热，建议对峰值和占空比进行评估与保护。
- PCB 布局：电感与相关电源回路应尽量缩短回流路径，沉铜与过孔可改善散热与电流承载能力。
- 焊接与可靠性：遵循推荐回流曲线完成 SMT 焊接，避免过多重复加热；存储与运输避免受潮与机械冲击。
- 测试建议：在目标工作频率与温度下验证电感值、直流电阻、温升与饱和特性，必要时索取完整测试曲线（L‑I、L‑f、温升曲线）。
六、可靠性与采购建议
选择器件前建议获取厂方完整数据手册与样品进行实装验证，关注批次一致性与老化特性。采购时注明型号 PSPMAA0803H-220M-ANP 与所需包装（卷带/盒装）以便对接；如用于车规或关键应用，请与供应商确认相关认证与寿命测试结果。
如需更详细的频率响应、饱和曲线与回流焊工艺参数，我可以帮您整理一份所需的测试项清单以便向供应商索取完整数据手册。

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.
