PSPMAA1265H-330M-ANF 产品概述
一、产品简介
PSPMAA1265H-330M-ANF 是谱罗德（PROD）推出的一体成型功率电感，标称电感值 33 μH，公差 ±20%，为表面贴装（SMD-2P）封装，外形尺寸 12.8 × 13.2 mm。该器件针对高电流开关电源与电源滤波场合设计，兼顾体积与散热能力，适合要求较大直流电流承载的输出滤波或能量储存场合。
二、主要技术参数
- 电感值：33 μH ±20%
- 额定电流（Ir）：7 A
- 饱和电流（Isat）：8 A（定义：电感降至额定值一定百分比时的电流）
- 直流电阻（DCR）：50 mΩ
- 封装：SMD-2P，尺寸 12.8 × 13.2 mm
- 类型：一体成型功率电感（molded）
三、性能特点
- 高电流承载：7 A 的额定电流适合中大电流的电源输出级与功率滤波。
- 可控饱和特性：8 A 的饱和电流为短时或峰值电流提供保护，但连续工作应以额定电流为准并留有裕量。
- 较低 DCR：50 mΩ 的直流电阻在高电流下仍会带来损耗（例如 7 A 时 P≈2.45 W），须在系统热设计中考虑散热与温升。
- 一体成型结构：机械强度与可回流焊工艺兼容，便于自动贴装与批量生产。
四、典型应用
- DC-DC 降压/升压转换器的输出滤波电感
- 电源管理模块（PMIC）、点对点供电
- LED 驱动、电机驱动与能量存储回路中需承载较大直流分量的场合
- 通信、电源备份系统等需要紧凑尺寸与较高电流能力的应用
五、封装与安装注意事项
- 按照厂家推荐的 PCB 版图布局焊盘设计，确保焊点充足以降低接触与焊接引起的热阻。
- 采用符合工业标准的回流焊工艺（参考厂商回流温度曲线），避免超温损伤封装材料。
- 布局时为降低热堆积，应在电感周围预留散热空间，必要时设计散热铜箔或热通孔。
六、选型与设计建议
- 电流裕量：建议实际工作电流低于额定电流（例如保留 20%-30% 的余量），以避免接近饱和区导致电感值下降。
- 损耗评估：按 P = I^2 × DCR 估算铜损，结合开关频率下的交流损耗与温升做热仿真。
- 频率特性：电感值在高频和加直流偏置时会下降，设计时应以实际工况测量或向供应商索取频率/电流特性曲线。
七、测试与维护建议
- 对样品进行温升、直流偏置下的电感变化以及饱和特性测试，验证在目标工作点的稳定性。
- 在长期运行中关注电感温度和焊点状态，定期检查有无过热或机械应力导致的裂纹。
如需器件详细的频率响应、温漂曲线、回流焊规范或更具体的应用电路建议，可联系供应商索取完整数据手册与应用说明书。

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.
