LQP03TNR27J02D 产品概述
一、产品简介
LQP03TNR27J02D 是 muRata（村田）出品的一款厚膜贴片电感，封装为 0201 小尺寸，电感量 270 nH，精度 ±5%。该器件面向微型化、高密度的射频与小信号电路，兼顾尺寸紧凑与稳定性要求。
二、主要电气参数
- 电感值：270 nH（±5%）
- 直流电阻 (DCR)：15 Ω
- 品质因数 Q：5 @ 100 MHz
- 自谐振频率 (SRF)：450 MHz
- 额定电流：60 mA
- 类型：厚膜电感
- 封装：0201
三、性能解读与适用场景
- 由于 DCR 较高（15 Ω），该电感在直流或低频通路会产生明显压降和功耗，不适合用于大电流或电源滤波主回路。
- Q≈5（100 MHz）说明在射频工作频段有中等损耗，适合用于阻抗匹配、射频阻断（小电流 RF choke）、带通/带阻网络的谐振元件或滤波器的微调。
- SRF=450 MHz 意味着在此频率以下电感值较为可靠，高于自谐频率时电感行为开始失真，因此选择工作频段应低于 SRF 较多以保证线性。
- 0201 超小封装利于手机、可穿戴、蓝牙/IoT 芯片周边的高密度布局，但对贴装精度与回流工艺要求较高。
四、封装与焊接建议
- 小尺寸封装对贴片机精度和锡膏印刷品质敏感，推荐使用精细锡膏模板与稳定的回流曲线。
- 回流时避免过急的温度梯度以减少陶瓷或厚膜层裂纹风险。
- 焊后如需钎焊或波峰，应确认工艺对 0201 的兼容性并做好可靠性验证。
五、选型与使用注意事项
- 若电路有持续高电流或要求低 DCR，应选用更大封装或金属线圈型电感；60 mA 的额定电流适合射频前端与信号路径而非电源主回路。
- 在高频滤波或谐振设计中，应考虑 Q 与 SRF 对带宽和损耗的影响，必要时进行实际板级调试并测量 S 参数。
- 环境温度升高会降低额定电流裕度，设计时应考虑热降额与实际 PCB 散热条件。
六、典型电路建议
- 用作天线馈线处的微型 RF choke，阻隔直流或低频干扰，同时尺寸小便于集成。
- 在滤波与谐振网络中与电容配合形成低通/带通结构，注意匹配 Q 与器件容差对中心频率的影响。
LQP03TNR27J02D 以其微型化与稳定厚膜工艺适合追求尺寸与集成度的射频与小信号应用，但在选型与布局时需充分考虑其高 DCR 与低额定电流的限制。

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.
