SMMS1040-470M是顺翔诺(SXN)推出的一款贴片式功率电感,专为中功率电子电路的储能、滤波及EMI抑制需求设计,采用紧凑SMD封装,兼顾电流能力与体积优势,适用于多种消费电子、车载及工业应用场景。
顺翔诺(SXN)作为国内专业电感制造厂商,其SMMS系列以高可靠性、宽电流范围及紧凑体积为核心特点。SMMS1040-470M属于该系列中功率型号,型号中“1040”对应封装尺寸(11.5×10×4mm),“470M”表示电感值47μH(“M”代表±20%精度),整体定位为中功率电路的核心电感元件。
该电感的电气性能是应用设计的关键依据,各参数含义及意义如下:
电感值为47μH±20%,实际范围在37.6μH~56.4μH之间。此范围满足大多数中功率DC-DC转换器、LED驱动电源的滤波及储能需求,精度设计兼顾成本与电路适配性,避免过高精度导致不必要的成本增加。
直流电阻为155mΩ,是绕组固有电阻,直接影响功耗(功耗=I²×DCR)。在3A额定电流下,功耗约1.4W,设计需预留PCB散热面积,避免温度过高降低寿命。
SMMS1040-470M采用SMD贴片封装,物理尺寸为11.5mm(长)×10mm(宽)×4mm(高),具有以下特点:
结合性能特点,该电感典型应用包括:
笔记本电脑、显示器、路由器等设备的降压/升压模块,3A额定电流满足中功率输出,47μH电感抑制纹波,提升电源效率。
车载充电器、显示屏、行车记录仪的电源电路,紧凑体积适配车载空间,4.5A饱和电流应对启动、负载突变的峰值冲击。
中功率LED照明(面板灯、汽车辅助灯)的驱动电路,47μH电感稳定电流,提升光效与寿命。
小型PLC、传感器节点的辅助电路,宽电流范围适配工业复杂工况,可靠性强。
SMMS1040-470M以平衡的性能、紧凑体积及可靠设计,成为中功率电子设备电源电路的优选元件,可有效提升电路效率与稳定性。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
