SMMS1385-220MT是顺翔诺(SXN)品牌推出的贴片式功率电感,专为中功率电源电路设计。型号中“SMMS”为系列标识,“1385”对应封装尺寸参数,“220”明确电感标称值为22μH(“MT”为精度及封装后缀)。产品采用SMD贴片封装,尺寸为13.8mm(长)×12.8mm(宽)×8.80mm(高),适配自动化贴装工艺,可直接集成于高密度PCB布局场景。
该电感的关键参数直接决定其在电源电路中的适用性,具体如下
电感标称值为22μH,精度范围±20%,即实际电感值在17.6μH~26.4μH之间波动。这一精度可满足绝大多数电源电路需求(如DC-DC转换、滤波),无需过度追求高精度,同时降低生产与选型成本。
产品DCR为22.8mΩ,属于低阻设计。DCR是绕组直流损耗核心参数,低阻意味着大电流下铜损(I²×R)显著降低,可提升电源转换效率3%~5%,减少散热需求(无需额外散热片)。
SMMS1385-220MT采用小型化贴片封装,具备以下工艺优势:
SMMS1385-220MT凭借高电流承载、低阻高效与小型化设计,成为中功率电源电路的高性价比选择,广泛适配消费电子、通信、工业等领域。

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.
