SMDRH105R-6R8NT 磁胶屏蔽功率电感产品概述

一、产品核心定位与基本属性

SMDRH105R-6R8NT是顺翔诺(SXN)品牌推出的贴片式磁胶屏蔽功率电感,属于中功率电感范畴,专为大电流、低损耗、低EMI的电子系统设计。采用SMD贴片封装,适配自动化贴装工艺,无需额外引线;磁胶屏蔽结构有效抑制电磁干扰,提升系统兼容性与稳定性,可满足工业、车载、消费电子等多领域的电源设计需求。

二、关键电气参数解析

该电感的核心参数直接决定其应用场景,具体如下:

1. 电感特性参数

电感值标称6.8μH,精度范围存在两种表述(产品描述标注±20%,基础参数表标注±30%),实际选型需参考原厂最新 datasheet 确认。电感值的稳定性是功率电感的核心指标,直接影响DC-DC转换效率及输出纹波控制效果。

2. 电流承载能力

  • 额定电流(Irms):5.35A:指电感在连续工作状态下,自身温度不超过额定温升(通常为40℃)的最大电流,是日常连续负载的安全上限;
  • 饱和电流(Isat):7A:指电感值下降至初始值80%时的峰值电流,是脉冲/瞬态负载的极限阈值。两者结合可覆盖“连续负载+瞬态冲击”的典型场景需求,避免电感饱和导致的性能下降。

3. 直流电阻(DCR)

DCR为20mΩ,属于低阻设计。低DCR可显著降低电流通过时的功率损耗(P=I²R),减少电感自身发热,同时提升电源转换效率(每降低1mΩ DCR,1A电流下可减少1mW损耗),降低系统整体功耗与热管理压力。

三、结构与封装优势

1. 磁胶屏蔽设计

区别于开放式电感,磁胶屏蔽结构通过磁胶包裹磁芯,有效抑制漏磁扩散,降低电磁干扰(EMI)。这一特性使其适合对EMI要求严格的领域(如车载电子、通信设备),减少对周边敏感电路的干扰,提升系统抗干扰能力。

2. 紧凑SMD封装

封装尺寸为10.4mm×10.3mm(长×宽),高度通常为5~7mm(需参考原厂 datasheet),属于中小尺寸贴片封装。紧凑的物理尺寸适配高密度PCB布局,可节省电路板空间,满足小型化电子设备(如笔记本适配器、车载充电器)的设计需求。

四、典型应用场景

基于参数特性,SMDRH105R-6R8NT适用于以下中功率电子系统:

  1. 开关电源/DC-DC转换器:如笔记本电脑适配器、LED驱动电源、工业电源模块;
  2. 车载电子设备:车载充电器、中控系统电源、车载音响电源(满足车载环境的振动与温度要求);
  3. 消费电子:智能家电电源、平板电脑快充模块、便携式储能设备;
  4. 工业控制:PLC模块电源、伺服电机驱动电源、机器人关节控制器。

五、可靠性与选型注意事项

1. 可靠性特点

磁胶屏蔽结构提升了电感的抗振动、抗冲击能力(符合车载级振动标准),同时低DCR设计减少了热应力,延长了产品使用寿命(典型MTBF可达10万小时以上)。需注意:电感实际工作温度需控制在额定范围(-40℃~+125℃)内,避免超过饱和电流导致电感值不可逆下降。

2. 选型要点

  • 连续负载电流需低于5.35A,瞬态峰值电流需低于7A;
  • 若系统对纹波要求严格,需确认电感精度(±20%/±30%)是否匹配;
  • 结合PCB布局空间确认封装尺寸是否适配,避免贴装干涉。

SMDRH105R-6R8NT凭借“低损耗、高电流承载、低EMI、紧凑封装”的综合优势,成为中功率电子系统的实用型电感选择,可有效平衡性能与成本,适配多场景电源设计需求。

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.
