村田LQP03TN27NJ02D贴片电感产品概述
一、产品基本信息
村田LQP03TN27NJ02D是muRata（村田）推出的高频贴片电感，属于村田LQP系列小型化电感产品。其封装规格为0201（公制0603），即英制尺寸0.02英寸×0.01英寸（约0.5mm×0.3mm），是当前电子设备中体积最小的贴片电感之一，适配高密度PCB设计需求。该产品针对射频、低功耗便携设备场景优化，兼具小体积与高频性能优势。
二、核心电性能参数详解
LQP03TN27NJ02D的电性能参数精准匹配高频应用需求，关键参数如下：
参数类型 具体数值 说明 电感值 27nH 固定电感量，满足射频电路匹配、滤波的基础电感需求 精度 ±5% 常规精度范围，保证批量生产一致性，适配大多数消费级/工业级场景 额定电流 140mA 最大允许直流工作电流，超过该值可能导致电感饱和、性能下降或损坏 直流电阻（DCR） 2.3Ω 直流工作状态下的电阻损耗，小电流场景下损耗可控，不影响电路效率 品质因数（Q值） 12@500MHz Q值=2πfL/R，反映电感储能与损耗的比值，500MHz下Q=12说明高频损耗低 自谐振频率（SRF） 2GHz 电感寄生电容与电感本身谐振的频率，工作频率需远低于SRF以保持电感特性三、适用应用场景
LQP03TN27NJ02D的小体积与高频性能使其适配以下典型场景：
- 射频通信终端：蓝牙5.0/5.1模块、Wi-Fi 2.4GHz频段收发器、物联网（IoT）终端的射频前端电路；
- 便携式电子设备：智能手机、智能手表、无线耳机的低功耗射频匹配网络、滤波电路；
- 高频滤波与匹配：射频收发器的阻抗匹配电路、低通/带通滤波器（针对500MHz~1.5GHz频段）；
- 小型化电源电路：低功耗设备（如智能手环）的DC-DC转换周边滤波（适配140mA以内小电流）。
四、产品优势特点
结合村田的工艺技术与参数设计，该产品具备以下核心优势：
- 超小体积适配高密度设计：0201封装可显著节省PCB空间，满足便携设备“轻薄化”需求；
- 高频性能优异：500MHz下Q值达12，自谐振频率2GHz，覆盖主流射频频段（2.4GHz以下）；
- 性能一致性稳定：村田成熟的薄膜电感工艺保证电感值精度±5%，批量产品参数偏差极小；
- 低损耗可靠性高：DCR仅2.3Ω，小电流下功耗低；贴片结构适配回流焊工艺，焊接可靠性强；
- 宽温范围适用：村田电感通常支持-40℃~+85℃工作温度，适配户外、工业场景的温度波动。
五、选型与使用注意事项
为保证电路性能稳定，需注意以下要点：
- 频率限制：实际工作频率应≤1.5GHz（远低于SRF 2GHz），避免谐振导致电感特性失效；
- 电流余量预留：若电路存在脉冲电流，需将连续工作电流控制在120mA以内（预留20%余量）；
- 焊接工艺要求：0201封装需采用精准回流焊温度曲线（峰值温度≤245℃，时间≤10s），避免虚焊或热损坏；
- 寄生参数考量：设计射频匹配电路时，需结合寄生电容（影响SRF）和DCR（影响损耗）优化参数，避免性能偏差。
综上，村田LQP03TN27NJ02D是一款专为高频小型化设备设计的高性能贴片电感，兼具小体积、高Q值、稳定精度等特点，是蓝牙、Wi-Fi、IoT终端等场景的理想选择。

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.
