PSPHAQ127-470M 产品概述
一、产品简介
PSPHAQ127-470M 是谱罗德（PROD）推出的一款功率型贴片电感，标称电感值 47 µH，公差 ±20%，适用于中低频开关电源与滤波电路。封装为 SMD，外形尺寸 12×12 mm，设计兼顾较大电感量与中等电流能力，适配空间受限但对电感值有要求的方案。
二、主要技术参数
- 电感值：47 µH（±20%）
- 额定电流：3.2 A
- 饱和电流（Isat）：3.2 A
- 直流电阻（DCR）：100 mΩ
- 封装形式：SMD，12×12 mm
- 品牌：PROD（谱罗德）
三、性能特性与工程含义
- 高电感量：47 µH 在较低开关频率系统（例如几十 kHz 至数百 kHz）中能有效抑制纹波与提供能量储存。
- 电流能力与饱和：额定电流与饱和电流均为 3.2 A，说明器件在接近额定电流时可能进入磁饱和区，设计时应留有裕量以免电感值骤降。
- 损耗评估：DCR 为 0.1 Ω，对应满载时的直流损耗 P = I^2·R。以 3.2 A 为例，P ≈ 3.2^2 × 0.1 ≈ 1.02 W，需注意温升与散热。
四、典型应用场景
- 降压（Buck）/升压（Boost）开关电源滤波与储能元件（中低频）
- 输入/输出滤波（电源模块、适配器）
- 汽车电子、工业控制与通信设备中对中等电流、高电感量的场合
五、封装与布局建议
- 采用 SMD 12×12 mm 尺寸，建议按厂家推荐的焊盘布局进行 PCB 设计，保证焊点充分湿润与可靠焊接。
- 由于 DCR 较高且满载损耗可达 1 W 以上，布局时应预留良好热散路径，可在焊盘下方或周围设计热铜皮和过孔以利散热。
- 推荐在贴装与回流焊工艺中遵循制造商的温度曲线与工艺规范，避免过热或机械应力损伤。
六、选型与使用注意事项
- 若系统连续工作电流接近或超过 3.2 A，建议选择额定电流更高、DCR 更低的电感，或并联多个电感以降低损耗与温升。
- 对于需在高频（MHz 级）下工作或要求极低纹波电流的场合，应评估电感的交流特性与自谐频率，必要时向供应商索取实际频率响应与饱和曲线。
- 在初期样机评估阶段，务必测量实际电感、DCR 及温升，验证在目标工作点下的性能并做相应热设计。
如需具体频率响应曲线、温升测试数据或 PCB 焊盘建议图，可联系供应商或提供样品进行测量与验证。

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.
