LQW15AN22NG80D 产品概述
一、产品简介
LQW15AN22NG80D 为村田（muRata）小型功率电感，封装尺寸为 0402（1.0 × 0.5 mm），电感值 22 nH，精度 ±2%，额定直流电流（Ir）780 mA，直流电阻（DCR）约 202 mΩ，非屏蔽结构。该器件针对高频电源及滤波场合设计，在超小体积下兼顾电流承载与频率特性，适合空间受限的移动和便携设备。
二、主要特性
- 电感值：22 nH，公差 ±2%（高精度等级，适用于对相位/频率稳定性要求高的电路）。
- 额定电流：780 mA，满足轻载到中等载流场景的电流需求。
- 直流电阻：约 202 mΩ，DCR 相对偏高，设计时应考虑功耗与发热。
- 封装：0402 超小型，利于高密度 PCB 布局。
- 类型：非屏蔽电感，磁通外泄相对较大，需注意对周围敏感器件的影响。
三、典型应用场景
- DC-DC 升降压转换器的输入/输出滤波与阻尼。
- 高频 EMI 滤波、射频旁路及阻抗匹配场合（需验证在工作频段的阻抗特性）。
- 手机、无线模块、可穿戴与便携式设备的电源管理与噪声抑制。
四、PCB 布局与使用建议
- 由于 DCR 较大，布局时尽量缩短与电源路径的走线，减小额外电阻与寄生电感。
- 非屏蔽结构可能有磁场外泄，敏感线路或天线应保持间距。
- 推荐使用制造商推荐的焊盘尺寸与回流曲线，避免热应力导致焊点开裂或器件位移。
- 在高温或接近额定电流时建议做热仿真与实际温升验证，必要时留有电流裕度。
五、选型与可靠性提示
- 若系统对功耗或发热敏感，优先考虑更低 DCR 或大包装电感；若受空间限制且需高精度，可采用本型号。
- 使用前应参考村田完整数据手册，查看频率响应、饱和曲线与温度特性曲线，以确保在目标工作点满足要求。
- 批量采购时注意封装标识与生产批次一致性，并做来料检验（LCR 与 DCR 测试）。

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.
