SM5845-3R3MT是顺翔诺(SXN)品牌推出的非屏蔽贴片功率电感,型号命名清晰对应核心参数:
作为中等功率电感,其核心定位是为电源电路、驱动模块提供稳定的储能与滤波功能,兼顾性能与成本控制。
标称电感值3.3μH,精度±20%(实际范围2.64μH~3.96μH),满足常规电源电路对电感精度的要求,无需额外高精度匹配,适配批量生产的一致性需求。
饱和电流为4A(电感值下降至初始值80%时的电流),是功率电感的关键指标:
直流电阻仅31mΩ(毫欧),显著降低电感的直流损耗:
采用SMD贴片封装,尺寸为5.8mm(长)×5.2mm(宽),典型厚度2.5mm(需参考官方datasheet),适配紧凑电路板设计:
该电感参数适配多种中等功率电路,常见应用包括:
该产品以平衡的性能、成本与尺寸,成为中等功率电子电路的实用选型,广泛适用于消费电子、工业与车载领域的常规电源设计。

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.
