LQP03HQ1N4B02D 产品概述 — muRata 0201 贴片厚膜电感
一、产品简介
LQP03HQ1N4B02D 为村田（muRata）生产的超小型厚膜贴片电感，封装 0201（0603 公制），电感值 1.4 nH。面向高频射频匹配与微型化电路，兼顾低直流损耗与高自谐振频率，适用于空间受限且对频率响应要求高的应用。
二、主要电气参数
- 电感值：1.4 nH
- 额定电流：1.1 A（最大直流通过能力，须注意温升）
- 直流电阻（DCR）：40 mΩ（典型值）
- 品质因数（Q）：20 @ 500 MHz
- 自谐振频率（SRF）：12 GHz
- 类型：厚膜电感（高频特性优良）
三、性能特点与优势
该器件尺寸极小，便于高密度布局；低 DCR 降低直流损耗，改善功率传输效率；Q 值和 SRF 指示其在多 GHz 频段仍能保持有效感抗，适合射频匹配、阻抗调节与谐振回路。厚膜结构在温度与机械应力下表现稳定，适合大批量表面贴装工艺。
四、典型应用场景
- 无线通信前端匹配网络（手机、WLAN、蓝牙）
- 射频滤波和阻抗调谐电路
- 高频混频器/放大器的偏置与去耦元件
- 紧凑型模块与天线匹配网络
五、设计与装配注意事项
在 PCB 布局上尽量缩短连接线以减少寄生电感和损耗；控制焊膏量与回流曲线，避免过量应力导致机械破坏；考虑额定电流与温升，如用于直流偏置应评估热裕量。高频设计时需基于实际 PCB 寄生参数做仿真与调试。
六、选型建议与可靠性
选择时综合考虑 SRF、Q、DCR 与额定电流，若工作频率接近 SRF，应确认器件仍能提供期望的相位与幅值特性。muRata 的厚膜工艺在可靠性与一致性方面表现出色，适用于需长期稳定性的消费电子与工业应用。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
