SMNR4030-100MT是顺翔诺(SXN) 推出的一款磁胶屏蔽功率电感,采用SMD贴片封装,外形尺寸为4×4×3mm(长×宽×高),属于小型化功率电感范畴,专为中小功率电子设备的电源管理场景设计。
该电感的关键参数明确且匹配中小功率应用需求,具体如下:
标称电感值为10μH,精度±20%,即实际电感值范围在8μH12μH之间。此电感值属于中低电感范畴,适配开关频率100kHz1MHz的DC-DC转换器(如降压型Buck电路),能有效抑制纹波电压并保证能量存储效率。
直流电阻为130mΩ,属于低损耗设计。DCR是电感铜绕组的直流电阻,电流通过时产生的铜损为(I^2×DCR),130mΩ的低阻值可显著降低功率损耗,减少发热,提升电源转换效率(尤其在1A1.5A电流区间,损耗仅0.13W0.29W)。
4×4mm的贴片 footprint 配合3mm高度,符合现代电子设备“轻薄化”趋势,可直接贴装于PCB板,无需额外插件空间,适配高密度电路设计。
采用磁胶屏蔽结构,可有效抑制电感工作时产生的电磁辐射(EMI),减少对周边敏感电路(如射频模块、传感器)的干扰,无需额外添加EMI滤波元件,节省PCB空间与成本。
4×4×3mm的紧凑体积,可集成于智能手机、智能手表等便携设备的电源管理模块(PMIC)周边,不影响设备整体厚度,适配“小型化”设计需求。
除130mΩ低DCR外,磁胶材料的铁损(磁芯损耗)也较低,整体功率损耗控制良好;饱和电流余量充足,长期工作不易出现磁芯饱和或绕组过热问题,可靠性符合消费电子、工业控制场景的使用要求。
该电感的参数与设计特点,使其适配以下场景:
智能手表、手环的低功耗电源电路(如3.7V锂电池转1.8V/0.5A),兼顾小体积与稳定电流输出。
微型PLC、传感器节点的电源部分(如24V转5V/0.6A),磁胶屏蔽可减少工业环境中的电磁干扰。
智能家电(如智能灯泡、传感器)、智能家居节点的电源模块,适配低功耗、小体积设计。
SMNR4030-100MT是一款小体积、高电流、低损耗、抗干扰的磁胶屏蔽功率电感,兼顾性能与成本,适配中小功率电子设备的电源管理场景,是顺翔诺针对便携、可穿戴、IoT等领域推出的高性价比产品。
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.
