PROD谱罗德PSPCAQ32-100M是一款针对小功率电源电路优化的表面贴装功率电感,核心参数明确且适配主流应用需求:
该电感采用SMD表面贴装封装,具体尺寸为:
3.0mm(长)×3.5mm(宽)×2.1mm(高)
小尺寸设计是其核心优势之一:可显著节省PCB布局空间,适配高密度、小型化电子设备(如可穿戴设备、物联网终端)的紧凑设计需求,避免因体积过大限制设备形态。
电流稳定性突出
额定电流与饱和电流均为900mA,意味着在设备实际工作电流范围内(≤900mA),电感值变化可控,不会因电流波动导致电感性能骤降,有效保障电源电路输出电压/电流的稳定性。
低损耗低发热
330mΩ的直流电阻处于同尺寸电感的较低水平,可降低铜损(电流通过电感线圈的能量损耗),减少工作时的热量产生——既提升电路效率,又降低对散热设计的要求(无需额外加装散热片)。
精度适配通用场景
±20%的电感精度符合工业级电源电路的设计标准,可覆盖大多数小功率DC-DC转换、EMI滤波等应用,无需额外投入高精度电感的成本。
结合参数与封装特点,该电感主要适用于以下场景:
可穿戴设备电源管理
如蓝牙耳机、智能手环、智能手表的升压/降压DC-DC电路——小尺寸适配设备紧凑空间,低损耗保障续航时长(避免因电感发热导致电池能量浪费)。
物联网终端节点
如环境传感器、智能门锁的低功耗电源模块——900mA电流满足节点工作需求,稳定性能保障数据传输可靠性(不会因电感性能波动导致传感器误判)。
小型移动电源
便携充电宝的升压电路(3.7V锂电池升压至5V)——小尺寸提升移动电源便携性,低DCR减少充电/放电过程中的能量损耗(提升转化率)。
小型家电控制电路
如智能台灯、加湿器、小型风扇的电源滤波电路——稳定性能保障设备工作稳定性,小尺寸适配家电小型化设计趋势。
电流限制
实际工作电流需严格控制在额定电流(900mA)以内,避免超过饱和电流导致电感值大幅下降,影响电路功能(如电源输出电压不稳定)。
焊接规范
采用回流焊工艺时,需遵循电感焊接温度曲线(峰值温度≤260℃,回流时间≤10秒),避免过热损坏线圈绝缘层或磁芯。
PCB布局建议
尽量将电感靠近电源管理芯片布局,缩短输入/输出线路长度——减少线路损耗,同时降低电磁干扰(EMI)对周边电路的影响。
存储环境
存储时保持干燥(湿度≤60%),避免引脚氧化影响焊接质量;远离腐蚀性气体与高温环境(≤85℃),防止磁芯性能老化。
PROD谱罗德PSPCAQ32-100M功率电感凭借小尺寸、低损耗、电流稳定性优异等特点,精准匹配小功率电子设备的电源管理需求,是可穿戴设备、物联网终端、小型移动电源等场景的高性价比选型。其兼顾性能与成本,能有效简化电路设计并提升设备可靠性,适合批量应用于消费电子、物联网等领域。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
