MHQ1005P2N0BT000 产品概述

一、产品简介

MHQ1005P2N0BT000 为 TDK 旗下0402(公制1005)封装的叠层陶瓷片式电感,标称电感值为 2 nH,额定直流电流 1 A。该器件针对高频应用优化,具有较高的自谐振频率(约 8 GHz)和在射频频段仍保持良好品质因数(Q ≈ 23 @ 250 MHz),适用于射频匹配、电源去耦与 EMI 抑制等对体积和频率性能有严格要求的场景。

二、主要电气参数

  • 电感值:2 nH(标称)
  • 额定电流:1 A(直流额定值)
  • 直流电阻(DCR):典型约 30 mΩ(有资料也见 50 mΩ 标注,实际以 TDK 数据表为准)
  • 品质因数:Q = 23(测量点 250 MHz)
  • 自谐振频率(SRF):约 8 GHz
  • 封装:0402(1005 公制)
  • 类型:叠层陶瓷 SMD 电感

补充电气量化说明:在 250 MHz 时 Q = ωL / Rser,可估算得到该频点的等效串联电阻约 0.14 Ω(约 140 mΩ),这反映出交流损耗随着频率上升明显高于直流 DCR。

三、性能特点

  • 高频性能优异:自谐振频率高达 ~8 GHz,适合 GHz 级信号处理与滤波场合。
  • 小型化:0402 尺寸利于高密度 PCB 布局,适合移动终端与射频前端模块。
  • 合理的电流承载能力:1 A 额定电流满足小功率供电及去耦需求;需留意大电流下的温升与电感偏移。
  • 稳定性:陶瓷叠层结构对温度与频率有较好的稳定性,但在强 DC 偏置下电感会有一定下降,具体曲线请参考原厂曲线。

四、典型应用

  • 射频匹配网络、带通/带阻滤波器的阻抗元件
  • 高频去耦与旁路(GHz 区域)
  • 天线匹配与前端滤波(手机、Wi‑Fi、蓝牙)
  • EMI 抑制与信号线滤波(高速差分线时需配合其他元件)
  • 小型电源网络的谐振/共模滤波(注意电流与温升)

五、封装与 PCB 布局建议

  • 尽量缩短与电感相连的走线,减少串联电感与寄生电容引入的影响,特别是在射频路径上应采用最短引线。
  • 将电感放置于靠近器件或接口的去耦点,避免在电感附近布置大面积敏感走线或高频噪声源。
  • 对于射频匹配,推荐与地面、邻近元件之间留出足够距离以控制寄生电容;底层需要良好地线以提供稳定参考。
  • 焊接工艺遵循 SMD 陶瓷电感的常规回流曲线与焊盘设计,避免过度机械应力;焊盘尺寸参照 TDK 推荐 land pattern。

六、选型注意与替代建议

  • 直流电阻与温升:虽然典型 DCR 约 30 mΩ,但在高频下等效损耗更大;若设计中允许更低损耗或更高电流,请考虑更大封装或更高电流额定的型号。
  • 自谐振频率要求:若工作频率接近或高于 SRF,应选择更高 SRF 的电感或采用无源匹配网络替代。
  • 替代型号:可在 TDK 或其他厂商(如 Murata、Coilcraft)中查找相近电感值(2 nH)、0402 尺寸且高 SRF 的片式电感,比较 Q、DCR 与额定电流后替换。

七、可靠性、操作与数据核对

  • 储存与处理:避免强机械冲击与长期潮湿环境,装配前遵循厂商关于回流与干燥(若适用)的建议。
  • 数据核对:本文给出的参数基于提供信息与典型计算,实际设计中应以 TDK 官方数据表及样片测量为准,若对 DC 偏置特性、温漂或耐压有严格要求,请向厂商索取完整规格与曲线图。

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
