PSPCAQ75-222K 产品概述
一、产品简介
PSPCAQ75-222K 是谱罗德（PROD）推出的一款表面贴装功率电感，标称电感值为 2.2 mH，公差 ±10%，针对低电流、电磁滤波和能量存储场合设计。封装为 SMD，尺寸 7.8 × 7 mm，适合体积受限但需要较大电感量的 PCB 应用。
二、关键参数一览
- 电感值：2.2 mH（±10%）
- 额定电流：260 mA
- 饱和电流（Isat）：260 mA
- 直流电阻（DCR）：4.85 Ω
- 封装形式：SMD，外形 7.8 × 7 mm
- 品牌：PROD（谱罗德）
三、性能特点与优势
- 大电感值：2.2 mH 能有效抑制低频纹波，适用于输入/输出滤波与降噪场合。
- 紧凑封装：SMD 形式便于自动贴装加工，7.8×7mm 在占板面积与电感量之间取得平衡。
- 稳定性：公差 ±10% 满足一般电源滤波和被动网络的电感精度需求。
四、注意事项与选型建议
- DCR 较大：4.85 Ω 的直流电阻在接近额定电流时会产生显著功耗（P = I^2·DCR），在 260 mA 下约 0.33 W，需关注温升与系统热设计。
- 电流裕量：饱和电流与额定电流相同，建议在实际应用中留出裕量（通常取额定电流的 50%~80%）以避免饱和与性能退化。
- 测试条件确认：实际电感值与频率、直流偏置有关，选型时向供应商确认测试频率与偏流条件。
五、应用场景
- 低电流 DC-DC 输出滤波或输入滤波（便携设备、传感器电源）。
- 模拟电路与音频电源去耦，抑制低频干扰。
- EMI 滤波网络中的低频储能元件。
六、封装与安装建议
- 采用推荐焊盘尺寸并保证良好焊接质量以降低接触电阻与热阻。
- 贴片回流工艺需遵循厂家推荐的温度曲线，避免过热引起磁性材料性能变化。
- 布局时尽量缩短与关键器件（如二极管、电容）的连接走线，减小寄生阻抗和电磁耦合。
七、可靠性与测试
- 使用前建议在预期工作温度和电流条件下进行温升与电感保持测试。
- 对长期可靠性关注磁心材料的老化、焊接可靠性和热循环影响，必要时要求厂方提供相关认证与实验数据。
总结：PSPCAQ75-222K 适合对电感值要求较高且电流较低的滤波与能量存储场合。在选型与设计时需特别注意其较高的 DCR 与电流裕量，结合系统热设计与测试验证可获得稳定可靠的应用效果。

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.
