LQP03HQ3N9B02D 产品概述

一、产品简介

LQP03HQ3N9B02D 为村田(muRata)出品的超小型贴片电感,封装为 0201(超小型 SMD),额定电感 3.9 nH。该器件专为高频应用设计,在 500 MHz 时具有约 20 的品质因数(Q),自谐振频率(SRF)约 7 GHz。典型直流电阻(DCR)约 170 mΩ,额定直流电流为 500 mA,适合对体积与高频性能有严格要求的终端产品。

关键参数一览:

  • 电感值:3.9 nH
  • 额定电流:500 mA
  • 直流电阻(DCR):170 mΩ
  • 品质因数(Q):20 (@500 MHz)
  • 自谐振频率(SRF):约 7 GHz
  • 封装:0201(贴片)

二、主要特性

  • 体积极小,适合空间受限的移动设备与高密度 PCB 布局。
  • 高频性能良好:在 VHF/UHF 及部分 GHz 频段仍能维持合理 Q 值,适用于射频匹配与滤波。
  • SRF 较高(约 7 GHz),在多数通讯频段(如 2.4 GHz、LTE 低频段等)以内仍可作为有用的无源元件使用,但接近 SRF 时电感值和损耗会显著变化。
  • DCR 相对偏高(170 mΩ),意味着在直流/低频大电流路径上会有一定功耗和压降,应在设计中予以考虑。

三、典型应用场景

  • 射频阻抗匹配网络(手机、蓝牙、Wi‑Fi、射频前端小信号匹配)
  • 高频滤波与谐振电路中的串联/并联元件
  • 信号链的去耦与旁路(对频段和功率有针对性要求时)
  • 微型化电子产品中作为高频旁路或短路元件使用

四、设计与使用注意事项

  • 布局:尽量靠近需要匹配或滤波的器件放置,连接走线尽可能短且宽度适配,以减少寄生电感与损耗。
  • 功率与温升:额定电流 500 mA 为最大持续值,超过会导致温升、参数漂移或元件损坏。直流电阻较大时需注意功耗(P = I^2·R)。
  • 频率特性:电感随频率靠近 SRF 时下降并最终表现为电容性,应在目标工作频段内测试实际电感与 Q 值。
  • 焊接可靠性:遵循厂商推荐的回流焊曲线与焊盘设计,避免过高温度和机械应力导致开裂或性能退化。
  • PCB 参考:在靠近地平面或有大面积金属区域时,电感的自谐振与寄生参数会变化,设计时应留意器件周边金属布局。

五、测试与可靠性建议

  • 在样机阶段使用 LCR 表与矢量网络分析仪(VNA)分别测量直流电阻、频率响应、Q 值与 SRF,以获取器件在实际 PCB 上的等效参数。
  • 进行温度循环与回流焊试验验证焊接可靠性;对长期工作在高温或高电流环境的应用,应做加速老化试验确认稳定性。
  • 关注批次一致性,必要时向供应商索取最新器件规格书与封装出货信息。

六、总结

LQP03HQ3N9B02D 是一款面向高频、要求极小封装空间的贴片电感,适用于射频匹配、滤波等应用场景。设计时需综合考虑其较高的 DCR 与电流承载能力限制,合理布线与热管理,并在目标频段内进行实际测量验证,以确保系统性能与可靠性。若需替代或批量采购,建议参考村田最新规格书并与供应链确认可供货性。

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.
