SPH252012HR24MT是顺络电子(Sunlord)针对中低功率电源管理场景推出的贴片功率电感,凭借小体积、高电流承载能力与低损耗特性,成为消费电子、工业控制、车载电子等领域高密度电路设计的优选器件。
该电感聚焦DC-DC转换电路的储能与滤波需求,核心设计目标是在紧凑封装下实现“高电流密度+低损耗+宽温可靠性”:既满足便携设备对小体积的要求,又能支撑工业/车载场景的宽温与高可靠性需求,同时通过低DCR降低电源转换损耗,提升系统效率。
标称电感值240nH,精度±20%——适配大多数降压/升压DC-DC电路的电感量需求(常规区间100nH~1μH),20%精度平衡了批量生产的成本与性能,避免因精度过高导致成本上升,同时满足电路对纹波抑制的基本要求。
额定电流(Irms)与饱和电流(Isat)均为4A——
直流电阻仅18mΩ——功率电感效率的核心指标:铜损P=I²×R,4A电流下铜损仅0.288W(同类竞品DCR多在25mΩ以上,铜损超0.4W)。低DCR可显著降低电源模块发热,减少散热设计难度,延长设备寿命。
采用SMD贴片封装,尺寸标识为252012(公制:2.5mm×2.0mm×1.2mm)或英制1008(0.10英寸×0.08英寸),属于小尺寸功率电感,适合高密度PCB布局(如笔记本主板、小型电源模块的紧凑空间)。

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.
