SMMS252010-2R2M是顺翔诺(SXN)推出的一款贴片式功率电感,专为小型化电子设备的电源管理电路设计,兼具小体积、合理电流承载能力与高效能特性,广泛适配消费电子、物联网终端等领域的中低功率场景。
该电感型号遵循行业通用命名规则:SMMS代表顺翔诺贴片功率电感系列;252010对应封装尺寸(结合产品描述为2×2.5mm贴片封装);2R2表示标称电感值为2.2微亨(μH);M为精度代码,对应±20%误差范围。作为一款SMD-2(双引脚贴片)电感,其核心定位是满足小型化设备的DC-DC转换、滤波等电源电路需求,平衡体积与性能。
标称电感值为2.2μH,精度±20%,即实际电感值范围为1.76μH~2.64μH。该精度范围符合大多数电源电路的设计容差要求,无需额外高精度补偿,降低电路设计复杂度。
直流电阻为70mΩ,属于同体积功率电感中的低阻水平。低DCR可显著减少铜损(功率损耗P=I²·R),提升电源转换效率,尤其在小电流场景下(如1A负载),铜损仅约70mW,对设备续航影响极小。
基于功率电感的典型特性,SMMS252010-2R2M适配100kHz~5MHz的工作频率范围,可满足常见DC-DC降压转换器(如Buck电路)的频率需求。
采用SMD-2双引脚贴片封装,尺寸为2mm(长)×2.5mm(宽),厚度符合功率电感的常规设计(结合型号252010推测为1mm左右)。小体积设计使其可集成于0402(英制)或1005(公制)等小型贴片元件的布局中,适配高密度PCB设计。
支持回流焊、波峰焊等自动化贴装工艺,焊接温度需遵循厂商规范(一般回流焊峰值温度≤245℃,时间≤10秒),确保封装与引脚的可靠性。
SMMS252010-2R2M的参数与封装特性,使其广泛应用于以下场景:
综上,SMMS252010-2R2M是一款性能均衡、适配性强的贴片功率电感,可满足多数小型化电子设备的电源管理需求,是性价比与可靠性兼具的选型方案。

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.
