PSPHAQ127-270M — PROD（谱罗德） 4A 27µH 功率电感 产品概述
一、产品简介
PSPHAQ127-270M 是谱罗德（PROD）推出的一款表面贴装功率电感，感值为 27µH，公差 ±20%。该器件为 SMD 封装，外形尺寸为 12×12mm，设计用于中低频开关电源和功率滤波场合。额定电流 4A，饱和电流（Isat）4A，直流电阻（DCR）约 46mΩ，适合对体积和电流能力有平衡要求的电源电路。
二、主要参数一览
- 型号：PSPHAQ127-270M
- 品牌：PROD（谱罗德）
- 电感值：27µH
- 精度：±20%
- 额定电流：4A
- 饱和电流（Isat）：4A
- 直流电阻（DCR）：46mΩ（典型值）
- 封装形式：SMD（表面贴装）
- 尺寸：12×12 mm
三、特性与优势
- 电流能力与体积平衡：12×12mm 的 SMD 封装在保持紧凑体积的同时，支持 4A 等级的连续电流，适合板级电源设计。
- 饱和电流匹配：Isat 与额定电流一致，说明在接近额定电流时磁芯进入饱和的临界较明显，设计时可考虑预留裕量以避免大幅度感值下降。
- 低至中等 DCR：46mΩ 的直流电阻在该尺寸与电流等级下属合理范围，有助于降低铜损，提高转换效率。
- 生产适配性：SMD 12×12mm 规格便于自动化贴装和回流焊工艺，利于批量生产和高密度 PCB 布局。
四、典型应用场景
- DC–DC 降压/升压转换器中的能量储存与滤波（尤其在中低频开关频率下）
- 电源输入滤波与输出滤波，抑制纹波与噪声
- LED 驱动、电机驱动与便携式电源模块
- 通信设备、电源管理模块和工业电子的 EMI 抑制回路
五、设计与使用注意事项
- 电流与饱和：尽量使实际工作电流（含直流偏置与纹波分量）低于 Isat，以避免感值在峰值电流时显著下降。对有较大纹波电流的方案建议留有裕度或选用 Isat 更高的型号。
- 损耗与温升：DCR 会导致功耗 P = I^2 × DCR，连续高电流运行会产生热量，应评估器件附近散热条件及环境温度，必要时进行热仿真与热管理。
- 回流焊工艺：遵循厂家推荐的回流温度曲线，避免过高回流温度或长时间高温暴露，以免影响磁芯材料与焊点可靠性。
- 布局建议：尽量缩短与电源开关元件、二极管等的连线长度，配置合适的旁路电容以形成低阻抗回路，减小辐射与环路干扰。
六、选型建议
- 若电路存在较大峰值电流或短时冲击电流，应选择额定电流与 Isat 更高的型号或在设计中增加裕量。
- 若追求更低损耗和更高效率，可选用同级别中 DCR 更小的器件；但需权衡体积与成本。
- 对于高开关频率应用，需关注高频特性（如饱和后频率响应、自谐频率等），必要时向厂商索取频率特性曲线和热稳定性数据进行验证。
如需该型号更详细的电气特性曲线、温升测试数据、回流焊工艺推荐或 3D 尺寸图纸，我可以协助整理并与谱罗德的规格资料对照提供进一步的选型支持。

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.
