TDK MHQ0402PSA15NHT000 贴片叠层电感产品概述

TDK作为全球电子元器件领域的标杆企业,推出的MHQ0402PSA15NHT000是一款针对高频小电流场景优化的01005封装叠层贴片电感。该产品凭借小型化设计、优异的高频性能及稳定的电气特性,广泛适配便携式电子设备、物联网终端等高密度电路需求,是射频前端、无线模块等场景的理想解决方案。

一、产品基本定位

该电感属于TDK小型化高频电感系列,采用陶瓷叠层工艺制造,核心面向低功耗、高频段、高密度PCB设计的应用场景。其型号命名中,“0402”对应公制封装尺寸,“15NH”明确电感值,“PSA”代表叠层电感特性,精准体现了产品的性能定位——为紧凑化电子设备提供可靠的射频信号调理支持。

二、核心电气参数详解

1. 电感值与精度

电感值为15nH,精度控制在**±3%** 范围内。该精度满足大多数高频电路的阻抗匹配需求,避免因电感偏差导致信号反射或损耗增加,尤其适合批量生产中对一致性要求较高的场景(如智能手机射频模块)。

2. 额定电流与损耗

额定电流为120mA(指电感表面温度上升不超过额定值时的最大持续电流),适配低功耗电路的电流需求;直流电阻(DCR)为1.68Ω,叠层工艺有效降低了内部电阻损耗,减少了电路的功率消耗,延长了电池续航时间(针对便携式设备)。

3. 高频性能指标

  • 品质因数(Q值):8@500MHz。Q值越高,电感的储能/损耗比越大,信号完整性越好,适合射频滤波、谐振等对损耗敏感的应用;
  • 自谐振频率(SRF):2.7GHz。该频率远高于主流工作频段(如2.4GHz蓝牙、500MHz以下GPS),避免了电感在工作频率下的谐振效应,保证电路性能稳定。

三、封装与物理特性

该电感采用01005封装(公制0402,英制01005),尺寸仅为0.4mm×0.2mm×0.2mm(典型值),是目前小型化贴片电感的主流封装之一,可大幅节省PCB空间,适配智能手机、智能手表等紧凑设计的设备。

物理特性方面,采用陶瓷叠层结构,具有以下优势:

  • 耐高温性能:可承受回流焊温度(峰值260℃左右),焊接兼容性强;
  • 抗机械应力:陶瓷材料稳定性高,不易因振动、冲击导致参数漂移;
  • 环保合规:符合RoHS、REACH等环保标准,满足全球市场准入要求。

四、典型应用场景

  1. 便携式电子设备:智能手机/平板的射频前端(天线匹配、滤波器)、蓝牙耳机的蓝牙模块(2.4GHz频段阻抗匹配)、智能手表的无线充电辅助电路;
  2. 物联网终端:低功耗Wi-Fi模块、蓝牙Beacon的射频滤波电路;
  3. 汽车电子:小型传感器(如胎压监测TPMS)的信号调理电路;
  4. 消费电子:便携式音箱的射频抗干扰电路。

五、产品核心优势

  1. 小型化高密度:01005封装为PCB布局节省约70%空间(对比0603封装),适配当前设备“轻薄化”趋势;
  2. 高频低损耗:Q值8@500MHz及DCR1.68Ω的组合,有效降低射频信号损耗,提升传输效率;
  3. 高稳定性:陶瓷叠层结构的温度系数低(典型值±30ppm/℃),环境温度变化对电感值影响小;
  4. 品牌可靠性:TDK成熟的叠层电感工艺保证了批量产品的一致性,降低了终端设备的生产良率风险。

六、适用注意事项

  1. 电流限制:避免超过120mA的额定电流,否则可能导致电感过热、参数漂移甚至损坏;
  2. 频率范围:建议工作频率低于2.7GHz(自谐振频率),若需在2.7GHz以上应用,需重新评估电路性能;
  3. 焊接工艺:采用符合IPC标准的回流焊曲线,避免焊接温度过高或时间过长损伤陶瓷结构;
  4. 存储条件:存储于常温(-40℃~85℃)干燥环境,避免潮湿导致引脚氧化影响焊接。

综上,TDK MHQ0402PSA15NHT000电感凭借小型化、高频低损耗、高稳定性等特性,成为便携式电子、物联网等领域的高性价比选择,可有效满足高密度电路的设计需求。

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.
