SMDRH104R-100MT 磁胶屏蔽功率电感产品概述

SMDRH104R-100MT是顺翔诺(SXN)推出的一款磁胶屏蔽式表面贴装功率电感,专为中小功率DC-DC变换电路设计,兼顾高电流承载能力与低电磁干扰(EMI)特性,广泛适配消费电子、车载电子及工业电源模块等场景。以下从核心特性、参数、应用等维度展开概述。

一、产品定位与典型应用场景

该电感属于中小功率级磁胶屏蔽电感,核心优势是“低EMI+高电流密度”,典型应用覆盖三类场景:

  1. 消费电子终端:笔记本电脑、平板的电源管理模块(PMU)、LED背光驱动电路、便携式充电器;
  2. 车载电子:车载USB充电器、ADAS辅助系统的低功耗稳压电路、车载显示屏电源;
  3. 工业与通信:小型PLC传感器模块、路由器/交换机的DC-DC转换单元、物联网终端电源。

其磁胶屏蔽结构可有效降低对外辐射干扰,适配对EMI敏感的电路设计(如模拟信号电路周边)。

二、核心电气性能参数详解

关键参数直接决定产品适用场景,需重点关注以下指标:

参数名称 规格值 意义说明 电感值 10uH±20% 满足多数DC-DC电路的电感量需求,±20%精度在量产中易匹配,降低BOM成本 额定电流(Irms) 3.8A 25℃环境下,电感自身温升≤40℃的连续工作电流,设计需留20%~30%余量 饱和电流(Isat) 5.6A 电感值下降至额定值70%时的峰值电流,是瞬间过载的关键安全指标 直流电阻(DCR) 35mΩ 低铜损设计,可减少功率损耗(P=I²R),提升电源转换效率 封装尺寸 10.4×10.3mm 近似1010封装,PCB布局空间友好,适配主流回流焊设备

注:工作温度范围默认适配-40℃~125℃(磁胶屏蔽电感常规宽温特性),满足车载/工业环境需求。

三、结构与封装特性

该产品采用磁胶屏蔽+树脂封装结构,区别于传统金属屏蔽电感的核心优势:

  1. 低EMI表现:磁胶材料对电磁辐射的屏蔽效果优于金属,可减少对周边敏感电路(如音频、射频)的干扰;
  2. 低损耗与宽频适配:磁芯损耗小,支持100kHz~1MHz高频应用(适合现代开关电源的高频化趋势);
  3. 机械可靠性:树脂封装提升抗振动/抗冲击能力,适配车载(振动环境)、工业现场(机械应力场景);
  4. 焊接友好:表面贴装引脚间距合理,回流焊过程中不易出现虚焊,量产一致性好。

四、品牌与可靠性说明

顺翔诺(SXN)作为国内专注功率电感的制造商,该产品通过以下工艺确保可靠性:

  • 自动化生产:采用绕线、磁胶填充、封装一体化自动化设备,参数一致性误差≤5%;
  • 环保合规:符合RoHS 2.0标准,无铅无卤,适配出口市场;
  • 测试验证:通过高低温循环(-40℃125℃,1000次)、振动(102000Hz,加速度2g)等可靠性测试,满足工业级基本要求。

五、选型与使用注意事项

  1. 电流余量设计:连续工作电流需≤3A(留20%余量),峰值电流≤5.6A(避免电感饱和导致输出电压跌落);
  2. 温度补偿:若工作环境温度>25℃,每升高10℃,额定电流需降低约10%(如65℃环境下,额定电流≈3.04A);
  3. PCB布局:电感周边需留≥2mm散热空间,避免与模拟信号走线平行(减少EMI耦合);
  4. 精度适配:若电路对电感精度要求≥±10%(如精密DC-DC),需更换更高精度型号,该产品±20%仅适合常规场景。

总结

SMDRH104R-100MT以“磁胶屏蔽低EMI+高电流密度+低DCR”为核心竞争力,是中小功率DC-DC变换场景的高性价比选择,尤其适合对电磁干扰敏感、需宽温适配的应用。其封装尺寸与参数匹配性,可直接替代部分进口同规格电感,降低成本的同时保证性能稳定。

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
