PSPNAQ3015-2R2M是谱罗德(PROD)品牌推出的表面贴装(SMD)功率电感,封装尺寸为3×3×1.5mm(长×宽×高),适配高密度PCB布局。核心参数及意义如下:
该电感针对小型化、高效率场景优化,具备以下实用特点:
3×3×1.5mm的紧凑尺寸符合SMD 1212(英制封装标识)标准,可直接集成于手机、IoT设备等对空间要求苛刻的终端产品,有效缩小整机体积,适配轻薄化设计趋势。
54mΩ的低DCR设计,在1.79A额定电流下,铜损功率仅约0.17W(计算:(P=I^2R=1.79^2×0.054)),热积累低,无需额外散热设计即可长期稳定工作,尤其适合便携式设备延长电池续航。
额定电流与饱和电流差值仅0.11A,说明磁芯材料线性度较好——接近额定电流时,电感值变化可控,避免因电感骤降导致DC-DC转换器纹波增大、效率下降。
采用高性能磁芯材料(常规功率电感常用铁氧体或合金磁芯),典型工作温度覆盖**-40℃至125℃**,可满足工业级(如车载辅助电路)及消费级场景的温度需求,可靠性高。
该电感主要适配中低功率电源电路,典型应用包括:
该电感采用无铅SMD封装,符合IPC-A-610标准,焊接及存储需注意:
PSPNAQ3015-2R2M以“小体积、高效率、宽温适配”为核心优势,是中低功率消费电子、IoT设备电源设计的高性价比选择。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
