LQG15HS2N2B02D 产品概述
一、产品简介
LQG15HS2N2B02D 为村田（muRata）系列贴片叠层电感，封装规格为 0402（1.0 × 0.5 mm 级别），额定电感量 2.2 nH。该器件面向高频与空间受限应用，兼顾射频性能与电流承载能力，适合移动终端、射频前端、滤波与阻抗匹配等场景。
二、主要参数
- 电感值：2.2 nH
- 直流电阻（DCR）：90 mΩ
- 品质因数（Q）：8 @ 100 MHz
- 自谐振频率（SRF）：6 GHz
- 额定电流：900 mA
- 类型：叠层电感（多层陶瓷芯片）
- 封装：0402（贴片）
三、特性与优势
- 小封装、高密度：0402 封装适合高密度 PCB 布局，节省空间。
- 高频适应性好：SRF 达 6 GHz，在 GHz 级应用中仍保持合理阻抗特性，适用于射频匹配与谐振电路。
- 平衡的损耗与电阻：DCR 为 90 mΩ，在小尺寸器件中表现出较低的直流损耗，有利于降低功耗与发热。
- 适度电流承载：900 mA 的额定电流使其在一些低功率电源滤波或供电回路中可直接使用，减少因电感饱和或温升带来的性能退化风险。
四、典型应用
- 射频输入输出端的阻抗匹配与谐振电路
- 高频滤波器（如 EMI 滤波、带通/低通网络）
- 无线通信模块、蓝牙/Wi‑Fi 前端匹配元件
- 空间受限的移动设备与可穿戴设备中的去耦与噪声抑制
- 低功耗 DC‑DC 转换器的旁路与滤波（在电流与损耗允许范围内）
五、PCB 布局与使用建议
- 尽量靠近信号源或器件放置，缩短信号回路的寄生电感与面积，获得更好的高频性能。
- 焊盘、走线应保持对称与最短，避免不必要的并联回路以降低 EMI 风险。
- 在靠近高频开关或天线时，注意隔离与地平面设计，避免互相耦合。
- 考虑直流偏置对电感值的影响：接近额定电流时电感可能下降，设计时应留有裕量。
- 贴片封装对回流焊工艺敏感，遵循厂商推荐的焊接温度曲线与吸湿处理规范以保证可靠性。
六、选型与注意事项
- 检查工作频段：若电路主要工作在接近或超过 SRF 的频率，需评估器件表现是否满足需求。
- 评估实际电流与热耗：长期接近或超过额定电流会引起温升与电感变化，必要时选择更高电流等级。
- 器件公差与温漂：实际应用中电感值会受制造公差及温度影响，关键电路建议做容差与温度裕量设计。
- 可靠性需求：若应用在高震动或高温环境，确认封装及基板配套工艺满足长期可靠性指标。
总结：LQG15HS2N2B02D 是一款针对高频和空间受限场合设计的 2.2 nH 0402 叠层电感，结合较低 DCR、6 GHz SRF 与 900 mA 的额定电流，在射频匹配、滤波与便携设备电路中具有良好的实用性。使用时建议关注直流偏置、布局和焊接工艺以确保性能稳定。

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.
