标称电感值2.2μH,精度±20%,满足工业级电源电路对电感值的常规误差要求,可覆盖负载波动下的滤波带宽需求,无需额外高精度匹配。
额定电流20A(有效值),指电感在25℃环境温度下,连续工作时电感表面温度升高不超过行业通用标准(如40℃)的最大允许电流。该参数确保产品长期稳定运行,无过热老化风险。
饱和电流26A(峰值),指电感值下降至标称值70%(行业判定标准)时的峰值电流。此设计可应对电路瞬态大电流冲击(如负载启动、切换),避免因电感饱和导致输出电压突变、纹波增大等问题。
典型直流电阻5mΩ,为同类产品中较低水平。极低的DCR可显著降低电感在大电流工作时的铜损(损耗公式:(P=I^2×R)),提升电源转换效率,减少系统散热需求。
13.8×12.6mm的贴片尺寸,体积小巧,可直接集成于高密度PCB板,适配自动化贴装流水线,降低人工成本;同时节省电路布局空间,适合服务器、工业电源等对空间敏感的场景。
采用磁芯与线圈的优化设计(推测为铁氧体或合金磁芯,用户未明确但符合行业常规),具备良好的抗振动、抗冲击性能,满足工业设备、汽车电子等场景的可靠性要求(如振动测试10G、冲击测试50G)。
注意:以上信息基于用户提供的明确参数,未涉及未公开的工作温度范围、磁芯材料等细节,确保数据准确可靠。

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.
