PSPHAQ127-331M 产品概述
一、产品介绍
PSPHAQ127-331M 为谱罗德（PROD）出品的一款功率型贴片电感，额定与主要参数为：电感值 330 µH（±20%），额定电流 1.3 A，饱和电流 Isat 1.3 A，直流电阻 DCR 640 mΩ。封装为 SMD，外形尺寸 12 × 12 × 8.0 mm。该器件适用于需要大电感量且电流要求不高的电源滤波、储能与噪声抑制场合。
二、主要特性与性能要点
- 电感量：330 µH ±20%，适合低频滤波与直流磁能储存。
- 电流能力：额定电流与饱和电流均为 1.3 A，表明在接近该电流水平时磁芯将接近饱和状态，应避免长期满载运行。
- 直流电阻：约 640 mΩ，较高的 DCR 意味着在较大直流电流下会产生显著的 I^2·R 损耗与温升。
- 封装与结构：SMD 贴装，尺寸 12×12×8.0 mm，利于自动化贴装与紧凑布局。
三、典型应用场景
- 输入/输出滤波器：用于开关电源输入侧或输出侧的低频滤波，配合电解/陶瓷电容减少纹波。
- 能量储存：低频降压/升压转换器中作为能量传输/储存元件（适用于开关电流较小的场合）。
- 噪声抑制：直流母线或电源模块的共模/差模噪声抑制（视电路拓扑而定）。
四、选型建议
- 安全裕量：建议工作电流保留 30%–50% 余量，即在 ≤0.8 A 左右工作以避免饱和和过高损耗。
- 注意 DCR：若电路对效率或温升敏感，应权衡 DCR 带来的功耗，不适合长时间大电流高效率场合。
- 直流偏置影响：高直流偏置会降低有效电感值，实际设计时应参考厂方 L–I 曲线或样品测量结果。
五、安装与可靠性注意
- 焊接工艺：遵循无铅回流温度曲线，避免过长高温暴露以保护磁芯与引脚。
- 布局建议：尽量缩短与电容、电源走线的距离，以降低回路电感与 EMI。
- 测试检验：建议进行温升、振动与跌落等可靠性验证，特别是在汽车或工业级应用中。
六、采购与技术支持
型号：PSPHAQ127-331M，品牌：PROD（谱罗德）。采购时请确认完整数据手册、温度系数、L–I 曲线、包装方式（卷带/盒装）及认证信息，必要时获取样品进行实际电路验证。若需进一步针对特定应用的选型或并联/串联方案建议，可提供电路参数以便给出更具体的建议。

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.
