LQP03HQ1N2B02D 产品概述

一、产品简介

LQP03HQ1N2B02D 是村田(muRata)生产的一款超小型厚膜贴片电感,封装规格为 0201(公制约 0.6×0.3 mm)。电感量为 1.2 nH,专为高频射频线路与紧凑型电子产品中用作阻抗匹配、滤波与共模/偏置阻断等用途设计。体积极小、性能稳定,适合空间受限且对高频性能有要求的应用。

二、主要规格

  • 电感值:1.2 nH
  • 额定电流(Irms):1.1 A
  • 直流电阻(DCR):40 mΩ
  • 品质因数(Q):20 @ 500 MHz
  • 自谐振频率(SRF):13 GHz
  • 类型:厚膜电感(薄膜/厚膜工艺)
  • 封装:0201(贴片)
  • 品牌:muRata(村田)

三、性能解读与设计要点

  • Q 值 20(@500 MHz)表示在该频段插入损耗较低,适合用于射频匹配网络与窄带滤波器。
  • 13 GHz 的自谐振频率表明器件在 GHz 级别内保持电感性,超出该频率将出现电容耦合与寄生谐振,应避免在接近 SRF 的频段作为纯电感使用。
  • 40 mΩ 的 DCR 对低频电源路径有一定影响,需在直流功率路径上评估压降与发热。
  • 额定电流 1.1 A 为连续通流能力,实际使用中应考虑温升与去磁饱和(建议留有裕量,按实际应用环境适度降额)。

四、封装与 PCB 布局建议

  • 0201 尺寸非常小,焊盘设计应参考厂商推荐尺寸,保证良好焊接润湿并留有适当焊膏覆盖。
  • 尽量靠近需滤波或偏置的器件放置,减小串联引线长度以降低寄生电感与损耗。
  • 对与地有关的滤波器件,确保附近有低阻抗回流路径(充足的过孔或地平面),避免环路面积增大造成 EMI 问题。

五、焊接与可靠性

  • 采用常规无铅回流焊接工艺;推荐遵循村田官方资料中的回流温度曲线与处理流程以保证可靠性。
  • 小封装对贴装精度要求高,注意抖动控制与贴装机压力设置。
  • 在高温或高湿环境下应进行可靠性验证(Thermal shock、Humidity、Mechanical shock),重点关注焊点强度与电感漂移。

六、典型应用场景

  • 手机、无线模组中的射频匹配与调谐电路
  • 高频滤波器、颈阻(shunt/series)网络
  • 高频电源去耦与偏置阻断(结合电容)
  • 紧凑型射频前端与天线匹配单元(BALUN、滤波阵列等)

七、测量与验证

  • 高频特性建议使用矢量网络分析仪(VNA)测量阻抗与 Q 值,观察插损与相位随频率的变化。
  • DCR 可用四端测量或高精度毫欧表测定;在实际电路中还需测量通流时的温升。
  • 在设计验证阶段做板上测试,评估装配应力与回流焊后性能一致性。

八、选型与采购建议

  • 若工作频段接近 SRF 或需要更高 Q,请咨询厂商或选择更高 SRF / Q 的器件。
  • 在大电流或功率敏感应用中,考虑 DCR 与降额使用,必要时选择更大尺寸或更低 DCR 的型号。
  • 采购时确认封装(0201)、批次与 RoHS 合规性,并索取完整数据手册与推荐焊接曲线以保证量产一致性。

以上为 LQP03HQ1N2B02D 的概述与实用设计要点,建议在最终设计时参考村田官方数据手册并在目标板级环境中进行充分验证。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
