LQP03HQ5N6H02D 产品概述

一、产品简介

LQP03HQ5N6H02D 为 muRata(村田)系列贴片厚膜电感,封装尺寸为 0201(0.6 × 0.3 mm 级别)。该器件以小型化与高频性能为设计目标,适合手机、无线模块及高频射频前端的小信号匹配与去耦场景。凭借紧凑尺寸与较高自谐频率,能在 GHz 级频段保持良好行为,便于高密度 PCB 布局。

二、主要电气参数

  • 电感值:5.6 nH
  • 公差:±3%
  • 额定直流电流:400 mA(连续)
  • 直流电阻(DCR):≈ 250 mΩ
  • 品质因数(Q):20 @ 500 MHz
  • 自谐振频率(SRF):5.5 GHz
  • 类型:厚膜电感(chip inductor)
  • 封装:0201(超小型贴片)

三、核心特点

  • 小体积:0201 封装适合高密度 SMT 布局,节省 PCB 面积。
  • 高频性能:SRF 高达 5.5 GHz,适用于微波频段匹配、滤波与谐振电路。
  • 较低 DCR:250 mΩ 的直流电阻在小电流应用中能够降低损耗,结合 Q=20 在 500 MHz 有良好选择性与插损控制。
  • 精度高:±3% 电感公差有利于精密匹配网络和可重复性生产。

四、典型应用

  • 射频匹配网络(L型、π型电感元件)
  • 微带滤波器与谐振电路(手机、蓝牙、Wi‑Fi 等)
  • 射频信号去耦与隔离(Bias‑T 中直流注入/隔离)
  • 高频接收前端、LNA 输入匹配与阻抗变换
  • 小型化消费电子与无线模组中的滤波/阻断用途

五、封装与焊接、PCB 布局建议

  • 使用标准 0201 SMT 贴装工艺,推荐遵循厂商的 PCB 焊盘图与回流焊曲线(避免过冲的热应力)。
  • 布局时尽量缩短信号线与电感引脚之间的走线长度,减少寄生电感/电容。
  • 系列电感应放置于信号路径短直处,避免弯折、急转或通过多处过孔。
  • 对于高频匹配场合,避免在电感下方形成大面积金属平面以减小与地的寄生电容;必要时可在地平面打窗或控制间距。
  • 为降低热阻与电流升温影响,评估实际 PCB 温升并在设计中留有电流裕量;400 mA 为器件标称额定值,连续工作时建议考虑一定的降额处理。

六、工程与设计注意事项

  • 高频特性受 PCB 邻近结构影响较大,建议在实际频段做 S 参数测量并在同样 PCB 布局下验证。
  • 对于滤波/阻抗变换电路,元件并联/串联时考虑寄生参数叠加,实际谐振频率会发生偏移。
  • 若用于 DC 供电注入或偏置网络,注意 DCR 导致的压降与功耗。
  • 在有严格相位/幅度要求的射频链路中,建议在工程样品阶段做温度与电流扫描测试以确认稳定性。

七、可靠性与测试建议

  • 遵循 IPC 推荐的 SMT 可靠性流程:回流焊后进行热循环、湿热与震动测试以验证焊接可靠性与电气参数漂移。
  • 对老化敏感的高频参数(Q、SRF、L)在不同温度、电流条件下做测量,建立退化模型与使用寿命评估。
  • 防止在装配过程中产生机械应力(取放或强压)导致芯片破裂。

八、总结

LQP03HQ5N6H02D 是一款面向高频、小信号应用的超小型厚膜电感,具有 5.6 nH、±3% 精度、SRF 5.5 GHz、Q=20(500 MHz)等性能,适用于射频匹配、滤波与去耦。工程设计时需重视 PCB 寄生影响、热与电流降额以及可靠性测试,按厂商数据手册与推荐工艺进行验证与量产控制。若需更详细的焊接曲线、封装图或 S 参数,请参考 muRata 官方数据手册或联系供应商获取完整资料。

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.
