SMMS1070-2R2MT功率电感产品概述
一、产品基本定位与核心特性
SMMS1070-2R2MT是顺翔诺（SXN）推出的中大功率贴片功率电感，专为电源系统的高电流、紧凑化需求设计。核心特性可概括为：
- 2.2μH标准电感值覆盖多数DC-DC拓扑需求；
- 34.5A额定电流+30A饱和电流支撑高负载场景；
- 5mΩ低DCR大幅降低铜损；
- 11.2×10.2mm SMD封装适配自动化生产与设备小型化。
二、关键电气参数详解
1. 电感值与精度
标称电感值2.2μH，精度±20%（实际范围1.76μH~2.64μH），符合工业电源对电感偏差的常规要求，无需额外校准即可匹配Buck、Boost等拓扑的工作逻辑。
2. 电流承载能力
- 额定电流（Irms=34.5A）：25℃环境下，电感温升≤40K的连续工作电流，确保长期稳定性（无过热衰减）；
- 饱和电流（Isat=30A）：电感值下降30%的电流阈值——该设计使电感在30A以内时，电感特性稳定，适配负载波动（如服务器CPU瞬态电流需求）。
3. 直流电阻（DCR=5mΩ）
采用低电阻漆包线绕制，铜损公式为(P=I^2·R)，在34.5A额定电流下，铜损仅约5.95W，比同封装竞品平均低15%，可提升电源转换效率1%~2%。
三、机械封装与工艺说明
SMMS1070-2R2MT采用表面贴装（SMD）封装，外形尺寸11.2mm（长）×10.2mm（宽），适配常规贴片生产线吸嘴规格，支持回流焊工艺（无引脚设计减少焊接缺陷）。
内部采用铁硅铝磁芯（顺翔诺专利优化），绕线工艺为多层密绕，既提升电流密度（单位面积承载电流），又减少漏磁干扰，适合对EMI要求严格的场景。
四、典型应用场景
- 服务器/数据中心电源：CPU、内存供电模块（12V转1V/2V大电流DC-DC），满足高算力下的瞬态电流需求；
- 工业控制电源：PLC、伺服驱动器电源单元，支持7×24小时连续高负载工作；
- 新能源设备：电动车车载充电机、光伏逆变器DC-DC环节，低损耗提升能源转换效率；
- 通信基站电源：5G基站射频单元供电，紧凑封装适配设备小型化设计。
五、性能优势总结
相较于同尺寸（11×10mm级）竞品，SMMS1070-2R2MT具备三大核心优势：
- 高电流密度：11.2×10.2mm封装承载34.5A额定电流，比竞品平均高10%；
- 低损耗设计：5mΩ DCR+优化磁芯，整体损耗降低15%以上；
- 可靠性稳定：饱和电流与额定电流的合理匹配（避免过载时电感突变），延长使用寿命至5万小时以上。
该产品兼顾性能与成本，是中大功率电源系统小型化升级的优选方案。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
