SMMS1050-2R2M是顺翔诺(SXN)推出的大电流低损耗表面贴装功率电感,针对电源系统的储能、滤波及EMI抑制需求设计,核心价值聚焦于「高电流承载能力+低损耗发热+紧凑封装适配」,可覆盖工业、车载、消费电子等多领域的中等功率应用场景。
电感值为2.2μH±20%,属于功率电感常用规格,精度满足工业级设备(±20%)的滤波/储能需求,无需额外校准即可适配常规DC-DC转换器、LED驱动等电路。
直流电阻(DCR):8.2mΩ:采用粗线径漆包线绕制,大幅降低铜损(功率损耗公式:(P=I^2R))。以13A额定电流计算,单只电感损耗仅约1.4W,显著减少电源系统发热,提升转换效率(如快充效率可超90%)。
采用铁氧体磁芯+多层漆包线绕制结构:铁氧体磁芯具备高饱和磁通密度,保障大电流下的稳定性;多层绕线减少趋肤效应(高频下电流集中在导线表面),进一步降低损耗。
工作温度范围为**-40℃+125℃**,满足工业级(-40℃+85℃)及车载级(-40℃~+125℃)环境要求,可在极端温度下长期稳定工作。
如需更大电流(如26A),可并联2只同型号电感,但需注意:
SMMS1050-2R2M凭借「高电流、低损耗、紧凑封装」的综合优势,成为中等功率电源系统的高性价比选择,可有效降低系统设计复杂度,提升电源效率与可靠性。

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.
