SMDRI125-101MT 磁胶屏蔽功率电感产品概述

一、产品定位与核心特性

SMDRI125-101MT是顺翔诺(SXN)推出的一款磁胶屏蔽式贴片功率电感,针对中低功率电源电路设计,兼顾「低损耗、抗干扰、易生产」三大核心需求。其核心优势包括:

  • 磁胶屏蔽结构:有效抑制电磁辐射,减少对周边敏感电路的干扰;
  • 低直流电阻(DCR):160mΩ阻值降低工作热损耗,提升电源效率;
  • 高饱和电流:1.9A峰值电流满足脉冲场景需求,避免电感饱和;
  • 标准SMD封装:12.3×12.3mm尺寸适配自动化产线,焊接兼容性强。

二、关键电气参数详解

参数是选型的核心依据,SMDRI125-101MT的关键参数及实际意义如下:

  1. 电感值与精度:100uH ±20%
    采用行业通用标识「101」(前两位为有效数字,第三位为10的幂次),±20%精度覆盖多数电源滤波、储能场景,无需额外高精度要求;
  2. 额定电流(Irms):1.3A
    连续工作电流上限,若超过此值,电感温升会超出安全范围,缩短使用寿命;
  3. 饱和电流(Isat):1.9A
    电感值下降30%时的峰值电流,是电路允许的最大瞬时电流(如开关电源脉冲峰值);
  4. 直流电阻(DCR):160mΩ
    电感线圈的直流电阻,阻值越小热损耗(I²×DCR)越低,160mΩ在同规格中属于偏低水平;
  5. 屏蔽类型:磁胶屏蔽
    相比非屏蔽电感,电磁辐射降低60%以上,适合对信号纯净度要求高的设备。

三、机械与封装规格

SMDRI125-101MT采用表面贴装(SMD)封装,机械规格适配主流产线:

  • 外形尺寸:12.3mm×12.3mm(长宽),高度约5mm(行业125封装常规高度);
  • 引脚设计:标准贴片引脚(间距适配常规焊盘),支持回流焊、波峰焊;
  • 材质:铁氧体磁芯+漆包铜线,耐温范围-40℃~+125℃,满足宽温环境需求。

四、典型应用场景

因性能均衡,这款电感广泛用于以下场景:

  1. 开关电源:AC-DC适配器、DC-DC降压/升压模块的输出滤波与储能;
  2. 移动电子:笔记本、平板的电池管理单元(PMU);
  3. 车载电子:车载充电器、LED氛围灯驱动、小型车载控制器电源;
  4. LED照明:LED球泡、面板灯的恒流驱动电路(稳定储能);
  5. 工业控制:PLC、传感器模块的辅助电源滤波。

五、选型与使用注意事项

为保证电路可靠性,使用时需注意:

  1. 电流匹配:连续电流≤1.3A,峰值电流≤1.9A,避免电感饱和;
  2. 温升控制:1.3A工作时功耗约0.27W(1.3²×0.16),需预留散热空间(避免密集布局);
  3. 焊接工艺:回流焊峰值温度240℃~260℃,时间≤10秒,防止磁芯/线圈损坏;
  4. 环境防护:避免潮湿、腐蚀性气体环境,若需则加防护套;
  5. 精度确认:±20%精度需核对电路容忍度,高精度需求需测试筛选。

六、品牌与可靠性说明

顺翔诺(SXN)是国内电感专业厂家,SMDRI125-101MT通过RoHS环保认证,符合REACH标准,生产采用全自动绕线+屏蔽工艺,产品一致性达98%以上,适合批量生产。

这款电感以「高性价比+均衡性能」成为中低功率电源的常用选型,能满足多数消费电子、车载、工业场景的需求。

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
