SMNR4030-2R2MT 功率电感产品概述

一、产品基本信息

SMNR4030-2R2MT是顺翔诺(SXN)品牌推出的磁胶屏蔽表面贴装功率电感,专为中小功率电源电路设计。型号命名规则清晰:“4030”对应封装尺寸(长×宽×高)为4mm×4mm×3mm,“2R2”表示标称电感值2.2μH,“MT”为磁胶屏蔽类型标识。该产品采用SMD(表面贴装器件)封装,适配自动化贴装生产线,可满足消费电子、工业控制等领域的小型化设计需求。

二、核心电气参数解析

SMNR4030-2R2MT的电气参数针对电源应用场景优化,关键性能如下:

  1. 电感值与精度:标称电感值2.2μH,精度±20%,满足多数DC-DC转换器的电感偏差要求,无需额外筛选即可适配常规电源电路。
  2. 电流承载能力:
    • 额定电流(Irms):4.1A,指25℃环境下长期工作、温升不超过允许值(通常≤40℃)的连续电流,可稳定支撑中等功率负载(如便携设备的主电源)。
    • 饱和电流(Isat):2.95A,指电感值下降至初始值80%时的电流,是避免磁饱和的关键阈值——电路峰值电流需控制在此值内,防止电感性能突变(如纹波增大、效率下降)。
  3. 直流电阻(DCR):39mΩ,属于低阻设计,可有效降低直流损耗,减少电感发热,提升电源转换效率(大电流场景下,低DCR的优势更显著)。

三、结构与封装特点

  1. 磁胶屏蔽结构:采用磁胶材料屏蔽,相比普通金属屏蔽电感,抗电磁干扰(EMI)性能更优——可减少电感对外辐射干扰,同时降低外界干扰对自身的影响,适合通信设备、医疗电子等对EMI敏感的场景。
  2. 小型化SMD封装:4mm×4mm×3mm的紧凑尺寸,适配0402(英制)/4030(公制)封装标准,可显著节省PCB空间,满足智能穿戴、便携设备等“轻薄化”设计需求。
  3. 贴装兼容性:表面贴装设计支持回流焊工艺,适配自动化生产流程,降低人工成本,提高量产效率。

四、典型应用场景

SMNR4030-2R2MT的参数特性使其广泛适用于以下场景:

  1. 消费电子电源:笔记本电脑、平板电脑、智能手表等便携设备的DC-DC降压转换器(如12V转5V、5V转3.3V),满足小体积、中电流的电源需求。
  2. LED驱动电路:小功率LED照明(台灯、屏幕背光)的恒流/恒压驱动模块,低DCR可减少驱动损耗,提升LED亮度稳定性。
  3. 工业控制模块:PLC(可编程逻辑控制器)、传感器节点的电源模块,磁胶屏蔽可降低工业环境中的电磁干扰影响。
  4. 车载电子:汽车中控屏、车灯辅助电源等低功率车载电路(需结合品牌可靠性验证,顺翔诺产品通常满足工业级基础要求)。

五、产品优势与价值

  1. EMI性能优异:磁胶屏蔽有效抑制电磁辐射,减少电路间干扰,降低系统EMI整改成本。
  2. 效率与发热平衡:低DCR(39mΩ)与合理的电流承载能力,可在保证功率输出的同时,减少电感自身发热,提升电源系统的可靠性与效率。
  3. 小型化适配性:4×4×3mm封装满足当前电子设备“高密度集成”趋势,可嵌入到紧凑PCB设计中。
  4. 成本与可靠性平衡:顺翔诺作为专业电感品牌,产品一致性好、贴装良率高,可降低客户的采购与生产综合成本。

该产品通过优化结构与参数,在“小型化、低损耗、抗干扰”三个核心维度实现平衡,是中小功率电源电路的高性价比选择。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
