LQP03HQ18NH02D 产品概述
一、产品简介
LQP03HQ18NH02D 是村田（muRata）出品的超小型0201封装贴片电感，标称电感值为 18 nH，公差 ±3%。该器件直流电阻（DCR）约 800 mΩ，额定直流电流 250 mA，在 500 MHz 时品质因数 Q≈20，自谐振频率（SRF）约 3.5 GHz。体积极小、频率响应良好，适合高密度与高频电路应用。
二、主要特点
- 极小封装：0201，占板面积小，有利于紧凑型与移动终端设计。
- 高精度：±3% 电感公差，利于精密匹配与滤波网络设计。
- 高频性能：Q=20@500MHz 与 SRF=3.5GHz，适合 VHF/UHF 及射频前端应用。
- 低电流容量：额定电流 250 mA，适合信号链而非大电流电源滤波。
- 较高 DCR：800 mΩ，需在电路设计中考虑功耗与直流压降。
三、典型应用场景
- 射频匹配网络、阻抗变换与谐振回路。
- 高频滤波器与带通/带阻结构。
- 天线匹配元件、收发模块输入输出匹配。
- 高频信号路径的去耦与隔离（低电流应用场合）。
四、设计与使用建议
- 直流偏置影响：在有直流通过时电感值可能下降，应评估工作电流下的有效电感。
- 电流限制：额定 250 mA，不宜用于大电流滤波或电源线感。
- 布局注意：尽量缩短与电感相连的走线，避免靠近大电流迹线与噪声源以降低寄生耦合。
- 温度与回流焊：遵循厂商回流温度曲线，避免超温导致性能退化或焊接故障。
- 测试验证：在目标频段进行矢量网络分析测量，确认实际 Q 值与 SRF 满足设计需求。
五、可靠性与采购建议
- 选型时参考村田完整数据手册，核实卷带包装、可追溯批号与环境等级（如钎焊耐温、湿度敏感等级）。
- 在样机验证阶段建议做热循环、振动及长期可靠性测试，以确认小型封装在终端产品中的稳定性。
如需进一步的封装尺寸图、回流曲线或批量供应信息，请根据型号 LQP03HQ18NH02D 向村田或授权分销商索取完整数据手册与样品。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
