Sunlord MPL1608S4R7MHT 贴片叠层电感产品概述

一、产品基本定位与封装特性

MPL1608S4R7MHT是顺络电子(Sunlord)推出的一款0603封装叠层贴片电感,专为高密度表面贴装设计,属于小型化电感系列。其封装尺寸对应公制1608(1.6mm×0.8mm),符合行业标准0603规范,适配自动化贴装设备,可有效节省PCB空间,满足便携式电子设备的小型化需求。作为叠层电感,该产品采用多层陶瓷介质与金属线圈一体化烧结工艺,无引线结构,具备体积小、一致性好、抗振动能力强等核心特点。

二、核心电气参数详解

该电感的关键参数明确,可覆盖多数小功率电路需求:

  1. 电感值与精度:标称电感值为4.7μH,精度±20%,满足普通滤波、储能电路的电感容差要求,无需额外高精度匹配;
  2. 电流特性:额定电流(Irms)为620mA,指电感在额定工作温度下长期稳定工作的最大交流电流有效值;饱和电流(Isat)为100mA,指电感值下降至初始值10%时的最大直流电流,直流应用需严格控制此电流;
  3. 直流电阻(DCR):450mΩ的低电阻设计,可减少电流通过时的功率损耗,提升电路效率,尤其适合低功耗应用场景;
  4. 自谐振频率(SRF):40MHz,表明在40MHz以下频率范围内,该电感主要表现为感性元件,可用于中低频(几十MHz内)的滤波、匹配电路。

三、工艺与材料优势

顺络的叠层电感工艺赋予该产品多项核心优势:

  • 陶瓷介质稳定性:采用高性能陶瓷材料作为介质,电感值随温度变化小,温度系数低,工作环境变化时性能稳定;
  • 一体化烧结结构:多层金属线圈与陶瓷介质一体化烧结,无焊接点,避免了传统绕线电感的引线损耗与接触电阻,同时提升机械强度;
  • EMI抑制能力:叠层结构的寄生参数(寄生电容、电阻)更小,对电磁干扰的抑制效果优于部分绕线电感,适合对EMI要求较高的电路。

四、典型应用场景

结合参数与工艺特点,MPL1608S4R7MHT主要适用于以下场景:

  1. 消费电子终端:手机、平板电脑的电源滤波电路(如DC-DC转换模块的输出滤波),满足小功率电源的储能需求;
  2. 便携式智能设备:蓝牙耳机、智能手环、智能手表的信号滤波与电源管理模块,适配设备的小型化设计;
  3. 物联网传感器节点:低功耗传感器的供电电路与射频前端滤波,符合节点设备的低功耗、小体积要求;
  4. 小型电子模块:蓝牙模块、WiFi模块的匹配电路,利用其40MHz以下的感性特性实现信号滤波。

五、可靠性与环境适应性

该产品具备良好的可靠性与环境适应性:

  • 环保合规:符合RoHS 2.0、REACH等国际环保标准,无有害物质,满足绿色电子设计要求;
  • 工作温度范围:典型工作温度为-40℃至+85℃,可适应多数户外与室内应用环境;
  • 耐焊接性能:支持260℃回流焊工艺(3次以内),贴装过程中性能稳定,无开裂或参数漂移;
  • 机械强度:一体化烧结结构抗振动、抗冲击能力强,适合运输与使用过程中的机械应力环境。

六、选型与使用注意事项

为确保电路性能,使用时需注意以下几点:

  1. 电流限制:直流应用需严格控制电流不超过100mA(饱和电流),交流应用需确保电流有效值不超过620mA,避免电感过热或性能下降;
  2. 频率匹配:电路工作频率应远低于40MHz(自谐振频率),若频率接近或超过40MHz,电感可能呈现容性,影响电路功能;
  3. 封装与焊盘:需采用与0603封装匹配的PCB焊盘设计,避免焊盘过大或过小导致贴装不良;
  4. 精度需求:若电路对电感精度要求高于±20%,需选择顺络其他高精度系列产品(如±10%或±5%精度的电感)。

总结:MPL1608S4R7MHT是一款性价比突出的小型化叠层贴片电感,体积紧凑、性能稳定,适合小功率、中低频的消费电子与便携式设备应用,是顺络电子针对高密度贴装场景推出的经典产品之一。

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.
