PSPMAQ0605H-330M-ANP 产品概述
一、产品简介
PSPMAQ0605H-330M-ANP 是谱罗德（PROD）推出的一款 SMD 型功率电感，标称电感值 33 μH，公差 ±20%，适用于中小功率开关电源与电源滤波场合。封装尺寸为 7.1 × 6.6 mm，针对板级自动贴装和回流焊工艺优化。
二、主要参数
- 电感：33 μH ±20%
- 额定电流（Irated）：2.5 A
- 饱和电流（Isat）：4.5 A
- 直流电阻（DCR）：210 mΩ（0.21 Ω）
- 封装：SMD，7.1 × 6.6 mm
- 品牌：PROD（谱罗德）
三、关键特性与优势
- 大电感值配合较高的饱和电流，适合需要较大磁通储能的降压/升压电路。
- 封装体积小，适用于空间受限的板级设计和便携式设备。
- SMD 封装利于自动化生产，可靠的焊接强度与机械稳定性。
四、典型应用场景
- 开关稳压器（DC‑DC 降压/升压）滤波与储能元件；
- 电源输入滤波（抑制大电流噪声）；
- LED 驱动与电机驱动等需要瞬态大电流的电源模块；
- EMI 抑制环节中的差模/共模滤波配合应用。
五、电气与热特性说明
- DCR 为 0.21 Ω，导致的直流功耗可用 P = I^2·R 估算：在额定电流 2.5 A 时，铜损约 1.31 W；在饱和电流 4.5 A 时，铜损约 4.25 W。实际温升还取决于 PCB 散热条件与脉冲/连续工作方式。
- 饱和电流表示线圈在较大直流偏置下磁芯接近饱和时的电流能力，超过 Isat 会导致电感值显著下降，应在设计中避免长期工作在饱和区。
- 开关纹波电流会增加等效损耗与温升，建议在计算损耗时考虑峰‑均方根（RMS）电流。
六、封装与安装建议
- 推荐短、宽的走线连接以降低额外串联电阻与寄生电感；关键焊盘处可设计热铜区域以改善散热。
- 回流焊工艺需遵循元器件耐温极限与厂商推荐的焊接曲线，避免长时间过高温度导致磁芯或包覆材料性能退化。
- 贴片时注意机械夹持与清洁，避免对电感主体施加过大力导致损伤。
七、选型建议与注意事项
- 若系统长期高负载工作，建议对额定电流做 20–30% 的余量，或选择更低 DCR 型号以降低损耗。
- 关注纹波电流与平均电流共同作用下的 RMS 值，基于 RMS 电流评估温升更为可靠。
- 在高频（上百 kHz 及更高）应用时需验证电感的频率响应与核心损耗，确保效率与温升满足要求。
八、采购与技术支持
如需样品或大量采购，请联系谱罗德授权经销商或代理，获取完整数据手册（包括温升曲线、频率特性、回流焊规范和可靠性测试报告），以便在具体项目中完成最终验证与可靠性评估。

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.
