SMDRI129-330MT 磁胶屏蔽功率电感产品概述

一、产品定位与核心属性

SMDRI129-330MT是顺翔诺(SXN)推出的一款SMD贴片式磁胶屏蔽功率电感,专为中高功率电源电路的储能、滤波及EMI抑制需求设计。该产品采用12.5×12.5×10mm紧凑型封装,兼顾高电流承载能力与低损耗特性,可广泛适配消费电子、工业控制、通信设备及车载电源等多领域,是小体积高密度电源设计的优选组件。

二、关键参数详解

核心参数直接决定产品应用适配性,具体解读如下:

  1. 电感值与精度:标称33μH,精度±20%(实际范围26.4μH~39.6μH),满足大多数DC-DC转换器、滤波电路的电感量需求,且精度范围适配量产一致性要求;
  2. 电流承载能力:
    • 额定电流(Irms)3.6A:额定温度下持续工作时,电感值变化≤10%的安全电流上限;
    • 饱和电流(Isat)4.25A:电感值下降30%时的临界电流,为过载/瞬态脉冲场景提供裕量;
  3. 直流电阻(DCR):52mΩ低内阻,显著降低自身功耗(如3.6A工作电流下损耗仅≈0.67W),减少发热并提升电源效率;
  4. 屏蔽类型:磁胶屏蔽工艺,相比传统屏蔽/无屏蔽电感,可有效抑制电磁辐射,降低对周边电路的干扰,符合EMC标准。

三、封装与工艺特点

  1. 封装规格:12.5×12.5×10mm SMD贴片封装,尺寸紧凑,适配主流自动化生产线,可直接集成于高密度PCB,节省电路空间;
  2. 磁芯与屏蔽:采用高性能铁氧体磁芯+磁胶复合结构,磁胶层增强屏蔽效果的同时,提升磁芯抗振动、抗冲击性能,且优化温度特性(-40℃~125℃宽温范围);
  3. 线圈设计:高导电率漆包线紧密绕制,保证电感值稳定一致性,进一步降低线圈内阻。

四、典型应用场景

该产品参数特性适配多场景需求:

  1. DC-DC转换器:笔记本电脑、服务器的降压/升压模块,3.6A电流满足CPU、内存供电,低DCR减少电源损耗;
  2. LED驱动电源:大功率LED(路灯、显示屏)恒流电路,电感储能保证电流稳定,磁胶屏蔽降低电磁干扰;
  3. 通信设备:基站、路由器的电源滤波电路,高电流承载适配高功率模块,屏蔽特性满足EMC标准;
  4. 车载电子:车载充电器、中控电源,宽温范围适配车载环境,抗振动性能保证可靠性;
  5. 消费电子快充:手机/平板快充充电器的PFC/DC-DC电路,3.6A电流满足快充功率,小体积适配紧凑设计。

五、产品优势与市场价值

  1. 高电流密度:12.5mm封装实现3.6A额定电流,单位体积电流承载突出,适配小体积高密度电源;
  2. 低损耗高效:52mΩDCR降低自身功耗,提升电源转换效率(如12V转5V/3A场景,损耗占比仅≈0.5%);
  3. 抗干扰性能佳:磁胶屏蔽抑制EMI,减少电路调试难度,符合电子设备电磁兼容要求;
  4. 可靠性稳定:±20%精度、宽温范围及抗振动特性,保证长期工作稳定性,降低维护成本;
  5. 性价比高:顺翔诺成熟工艺,在保证性能前提下具备成本优势,适合批量应用。

总结

SMDRI129-330MT凭借紧凑封装、高电流承载、低损耗及抗干扰等核心优势,成为中高功率电源电路的高性价比选择,覆盖多领域应用需求,为电子设备的小型化、高效化设计提供可靠支撑。

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.

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
