PSPNAQ3015-2R2M功率电感产品概述

一、产品核心参数与规格定义

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:

  • 电感值:2.2μH,精度±20%——满足中低功率电路的储能、滤波需求,宽精度范围适配成本敏感型设计;
  • 额定电流(Irms):1.79A——电感连续工作时,自身温升不超过常规限值(如20℃)的最大电流,是长期可靠工作的核心参考;
  • 饱和电流(Isat):1.9A——电感值下降至初始值80%时的峰值电流,是电路瞬间过载的性能边界;
  • 直流电阻(DCR):54mΩ——绕组的直流电阻,低DCR可显著减少铜损,提升电源转换效率。

二、设计特点与性能优势

该电感针对小型化、高效率场景优化,具备以下实用特点:

2.1 高密度小封装设计

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。

2.2 低损耗高效率

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。

2.3 稳定的电流承载能力

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。

2.4 宽温适应性

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。

三、典型应用场景

该电感主要适配中低功率电源电路,典型应用包括:

  1. 消费电子终端:智能手机、平板电脑、智能手表的DC-DC降压模块(5V转3.3V/1.8V),负责储能与滤波;
  2. 便携式设备:蓝牙耳机、智能手环、移动电源的小功率电源管理,低DCR降低电池功耗;
  3. IoT与智能家居:智能音箱、温湿度传感器、智能门锁的电源电路,紧凑封装适配小型化模块;
  4. 汽车电子辅助电路:车载USB充电接口、仪表盘背光电源的小功率DC-DC转换,宽温范围满足车载环境(-40℃至85℃)。

四、封装与焊接兼容性

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:

  • 回流焊工艺:支持无铅回流焊,峰值温度需控制在240℃以内(时间≤10秒),避免磁芯过热损坏;
  • PCB布局建议:电感焊盘需匹配电源回路铜箔面积,避免电流集中导致焊盘过热;周围预留1mm以上散热空间;
  • 存储要求:未开封产品需存于25℃±5℃、湿度40%~60%环境,避免受潮影响焊接性能。

五、选型与使用注意事项

  1. 电流选型:连续工作电流≤1.79A,峰值电流≤1.9A,避免过流导致电感饱和或过热;
  2. 精度适配:±20%精度适合电源滤波、DC-DC转换,若需高精度滤波(如射频电路)需换更高精度型号;
  3. 高温降额:100℃以上环境工作时,每升高10℃,额定电流降约5%,确保长期可靠性;
  4. 机械应力:焊接时避免过大压力,防止磁芯破裂或绕组变形,影响电感性能。

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。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
