LQG15HS4N7B02D 产品概述
一、产品简介
LQG15HS4N7B02D 为村田（muRata）生产的叠层贴片电感，封装规格为 0402（1.0 × 0.5 mm 尺寸级别）。标称电感值为 4.7 nH，公差 ±0.1 nH，属于小尺寸、高密度电路常用的射频/高频电感元件，适用于空间受限的移动终端、射频前端及高频滤波匹配网络。
二、主要电气参数
- 电感值：4.7 nH ±0.1 nH（约 ±2.1%）
- 额定直流电流：700 mA
- 直流电阻（DCR）：160 mΩ
- 品质因数（Q）：8 @ 100 MHz
- 自谐振频率（SRF）：6 GHz
- 类型：叠层电感，贴片（0402）
三、频率特性与典型应用
该器件在低于自谐频率（约 6 GHz）范围内表现为电感性元件，适合用于：
- RF 匹配网络（天线匹配、射频滤波）
- 偏置堵路/射频旁路（bias choke）
- 高频滤波与阻抗调节
由于 Q 值在 100 MHz 时约为 8，属于中等损耗类型，适合对插入损耗容忍较高或需要小体积的场合，而非追求超高 Q 的谐振回路。
四、封装与装配注意
0402 小尺寸对贴装与焊接工艺敏感：
- 推荐按厂家推荐的 PCB 焊盘尺寸与焊膏印刷模板进行布局，确保良好焊接可靠性。
- 采用标准回流焊工艺，避免超温或长时间高温循环以防元件损伤或电感值漂移。
- 元件为非极性，可任意方向贴装；但在高密度设计中应注意与其他元件之间的磁耦合与热影响。
五、设计与选型建议
- 工作频段应尽量低于 SRF，以保持电感性特性；靠近 SRF 时电感值会明显变化且可能产生并联/串联谐振。
- DCR 较大（160 mΩ），在对直流损耗或功率损耗敏感的应用中需评估发热与电压降。
- 额定电流 700 mA 需要考虑直流偏置导致的电感降低，设计时建议留有余量避免饱和效应影响电路性能。
- 若需更高 Q 或更低 DCR，可参考更大尺寸或不同材料的型号。
六、测试与可靠性
- 推荐使用网络分析仪测量阻抗/相位和 S 参数以确认实装频率响应，测试时注意去除测试夹具影响（去嵌入）。
- 在实际工程中应进行温度循环和回流后测试，验证电感、DCR 与 SRF 的漂移满足长期可靠性需求。
总体而言，LQG15HS4N7B02D 以其小体积与良好的高频特性，适合在空间受限的射频前端与高速信号路径中作为通用型小电感件使用。

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.
