LQW15CNR33J10D 产品概述
一、产品概况
LQW15CNR33J10D 是村田（muRata）生产的0402 封装功率电感，标称电感值 330 nH，公差 ±5%。该器件为非屏蔽片式功率电感，适合在体积受限的表贴电源和滤波电路中使用。封装尺寸为 0402（约 1.0 × 0.5 mm），适配高密度贴装需求。
二、电气参数要点
- 电感值：330 nH（±5%）
- 额定电流：390 mA（持续工作电流参考）
- 直流电阻（DCR）：约 560 mΩ（典型值）
- 类型：非屏蔽功率电感 这些参数决定了在通直流偏置下的电压损耗、温升和电感下降趋势，需结合实际工作频段评估交流阻抗及自谐频率。
三、主要特性与优势
- 小型化：0402 封装满足紧凑布局和便携设备的尺寸要求。
- 低频功率处理能力：390 mA 的额定电流在小型电源和滤波场景中能提供可靠的电流承载。
- 可控损耗：560 mΩ 的 DCR 在抑制直流功率损耗与体积限制间提供平衡，适合低功耗或中低功率路径。
- 稳定性：村田产线工艺保证元件一致性和长期可靠性，适合量产使用。
四、典型应用
- 移动设备与便携终端的小功率 DC-DC 降压/升压转换器输入/输出侧滤波。
- 电源去耦与EMI 抑制网络。
- 传感器供电回路、时钟/参考电源滤波。
- 需要空间受限的消费电子、工业控制小功率场景。
五、设计与布局建议
- 紧靠开关IC 布局，减少走线电感和回流环路面积以降低 EMI。
- 注意 DCR 带来的功耗与温升，必要时在热设计中预留余量并进行热仿真。
- 考虑直流偏置导致的电感下降：在高偏置下实际电感可能降低，应参考厂商曲线。
- 推荐采用标准回流焊工艺，避免过度挠曲和机械应力，确保焊盘尺寸与厂商推荐一致。
六、可靠性与选型提示
- 选型时除额定电流外，应关注饱和电流与交流阻抗、self-resonant frequency（自谐频率）等参数，以满足目标频段的滤波需求。
- 对于需要更高电流或更低 DCR 的场合，考虑更大封装或同系列不同规格产品。
- 建议在目标温度与电流条件下做实际测量验证，考虑长期老化与温漂影响。
七、包装与订购信息
- 品牌：muRata（村田）
- 封装：0402，卷带盘装（Tape & Reel，适合贴片机直接贴装）
- 物料号：LQW15CNR33J10D，订购时请确认批次与规格一致，需关注 RoHS 和客户特定测试要求。
如需原厂详细频率响应、直流偏置曲线或推荐焊盘图，可进一步获取村田规格书或索取样品以便开展电路验证。

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.
