SMNR8040-102MT是顺翔诺(SXN)针对小型化、低EMI需求推出的贴片功率电感,采用磁胶屏蔽设计,兼具小体积与高可靠性,适用于各类便携及低功耗电子设备的电源管理与滤波场景。
该电感定位于中小功率密度电源系统的储能与EMI抑制,聚焦便携电子、IoT终端、小型通信模块等细分领域。其小体积(8×8mm贴片封装)、低功耗(低DCR)与磁胶屏蔽特性,可有效适配设备的紧凑布局与电磁兼容要求,是替代传统非屏蔽电感的优选方案。
电感标称值为1mH(102标识),精度±20%,满足大多数电源滤波、DC-DC转换的储能需求。电感值在额定电流范围内保持稳定,无明显饱和衰减(饱和电流与额定电流一致),可确保电路工作性能一致性。
DCR标称值为3.64Ω,在400mA工作电流下,功耗约为0.58mW(P=I²R),属于低功耗水平,可有效降低电源系统的热损耗,延长设备续航。
采用SMD 8×8mm贴片封装(行业标准8040封装,长8mm×宽8mm),引脚间距符合IPC-A-610规范,适配自动化SMT贴装,兼容各类小型化PCB布局。
磁胶屏蔽是SMNR8040-102MT的核心设计亮点,相比传统非屏蔽电感,具备三大优势:
符合SMT回流焊规范,峰值温度260℃±5℃(时间≤10s),引脚采用镀锡工艺,焊接牢固,无虚焊风险;
在额定工作条件下,平均无故障时间(MTBF)超过10万小时,长期工作后电感值、DCR变化率均控制在5%以内;
引脚采用ESD防护设计,可承受8kV接触放电与15kV空气放电,避免生产、使用过程中的静电损坏。

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.
