PSPNAQ252012-2R2M是PROD(谱罗德)针对中低功率电路推出的小型化功率电感,核心参数精准匹配便携电子设备的电源管理需求:
该电感采用252012小型化SMD封装,是当前便携设备中空间优化的主流选择:
标称2.2μH±20%的电感值,覆盖了DC-DC转换器的常用范围(典型降压电路电感多在1μH~10μH之间)。±20%的精度无需额外的精密匹配,可通过反馈环路调整保证稳压精度,同时降低了元器件成本。
低DCR是该电感的核心优势:在1.85A额定电流下,导通损耗仅为0.54W(公式:P=I²×R),相比同尺寸200mΩ电感,损耗降低约20%,可有效减少电路发热,延长电池供电设备的续航时间(如智能手表单次充电续航提升5%~8%)。
结合小型化、低损耗、电流裕量充足的特点,该电感主要适用于以下场景:
该电感是便携电子设备电源管理的高性价比选择,兼顾小型化、低损耗与可靠性,可有效降低电路设计的复杂度与成本。

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.
