LQW18AN5N6C00D 产品概述

一、产品简介

LQW18AN5N6C00D 是村田(muRata)生产的一款0603 封装非屏蔽功率电感,标称电感值为 5.6 nH,额定电流 750 mA,直流电阻(DCR)约为 82 mΩ。该器件体积小、适用于高密度表贴电路,主要用于高频滤波、去耦与电源路径阻抗管理等场合。属于 SMD 功率电感系列,兼顾电流承载能力与微小封装下的低阻抗特性。

二、主要电气参数

  • 电感值(L):5.6 nH(标称)
  • 额定直流电流:750 mA(连续工作参考值)
  • 直流电阻(DCR):82 mΩ(典型值)
  • 类型:非屏蔽电感(unshielded)
  • 封装:0603(俗称 1608 公制)

这些参数表明该电感在低纳亨量级别具有较低的电阻损耗,适合高频路径上的干扰抑制与阻抗调节。

三、性能与典型应用场景

  • 高频 EMI / RFI 抑制:5.6 nH 为较低感值,适合 GHz 级别或高频带的共模/差模噪声抑制与匹配。
  • 电源去耦与滤波:用于 DC-DC 转换器输出端或开关节点的旁路与谐振控制,结合电容可形成低通或带阻滤波网络。
  • 射频链路与高速数字信号:在需要控制阻抗或吸收高频干扰的信号线上可用作小电感阻尼单元。
  • 移动设备与消费电子:适配小尺寸 PCB 与高密度布局场景。

注意:非屏蔽结构在高频下可能产生一定的磁场泄漏,需要在对电磁兼容(EMC)敏感的应用中评估干扰影响或采用屏蔽型器件替代。

四、功耗与热特性评估

基于给定 DCR 可计算器件在额定电流下的损耗与压降:

  • 电阻压降 V = I × R = 0.75 A × 0.082 Ω ≈ 0.0615 V
  • 铜耗 P = I^2 × R = (0.75^2) × 0.082 ≈ 0.046 W(约 46 mW)

尽管损耗较小,但在实际设计中应考虑:

  • 连续工作时的温升与散热路径(小尺寸器件对热积累更敏感)。
  • 电感随直流偏置电流的磁饱和或电感值下降;实际电感值会随直流电流增加而降低,应在电路仿真或实测中确认是否满足滤波需求。
  • 建议在长期连续工作时对额定电流进行适当降额(常见经验为 70%–80%),以保证可靠性与温升余量。

五、封装、安装与可靠性要点

  • 0603 封装便于高密度贴装,但对焊接与机械应力更敏感。推荐遵循村田的回流焊接曲线并严格控制焊接工艺参数。
  • PCB 着陆窗(pad)应满足标准 0603 SMD 封装要求,保证良好焊接湿润与机械支撑;避免在靠近器件底部形成气泡或焊膏过量。
  • 清洗与残焊处理需符合常用工业规范,避免腐蚀或焊渣影响器件长期性能。
  • 由于为非屏蔽结构,器件附近应避免对敏感信号线产生磁耦合;必要时通过布局、地平面或增加屏蔽器件来降低干扰。

六、选型与使用建议

  • 若设计对电磁泄漏敏感或需要更稳定的电感值,优先考虑屏蔽型或更大体积的电感元件。
  • 在滤波器设计中,结合电容选取合适的谐振频率,并关注电感在工作电流下的实际值。
  • 对于高温或连续高功率应用,应参考厂方 datasheet 的温升与最大工作温度,必要时使用频率扫描与温升测试验证。
  • 采购前应确认供应包装(卷带、盘装等)、批次与储存条件,避免受潮或高温导致性能偏移。

七、质量与采购参考

村田作为国际知名的被动元件供应商,该型号通常有稳定的制造工艺与质量控制。正式设计和量产前应查阅并保存最新官方 datasheet,以获取完整的电气、热与机械规格、测试条件和建议的 PCB 布局图。订购时确认完整型号(LQW18AN5N6C00D)、包装方式与数量,并考虑样品验证以确保与系统兼容。

如需更详细的测试曲线(电感随频率/直流电流的变化、温升曲线等),建议直接参考村田官网 datasheet 或向销售工程师索取完整规格表与应用笔记。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
