LQP03TN47NH02D 产品概述 — muRata(村田)47nH 0201 贴片厚膜电感

一、主要参数和性能概览

  • 产品型号:LQP03TN47NH02D
  • 品牌:muRata(村田)
  • 封装:0201(超小型片式)
  • 电感值:47 nH ±3%
  • 额定电流:100 mA
  • 直流电阻(DCR):3.6 Ω
  • 品质因数(Q):9 @ 300 MHz
  • 自谐振频率(SRF):1.3 GHz
  • 类型:厚膜片式电感(chip inductor)

该器件以超小封装实现中高频段的电感功能,适合对面积与高度有限制且侧重射频/高频特性的应用场景。

二、主要特性与优势

  • 体积极小:0201 封装节省 PCB 面积,适用于空间受限的移动终端、穿戴设备及紧凑型无线模块。
  • 高频性能匹配:Q 值在 300 MHz 时为 9,自谐振频率 1.3 GHz,适用于 VHF/UHF 以及更高频段的匹配和滤波用途。
  • 稳定精度:±3% 电感公差,利于频率设计与滤波器重现性。
  • 易于贴装:适配常规贴片回流工艺,可与 SMD 自动贴装设备配合使用。

三、典型应用场景

  • 射频网络:匹配网络、谐振回路、带通/带阻滤波器的元件。
  • 无线通信模块:射频输入/输出匹配、阻抗变换、电感型负载等。
  • EMI/ESD 抑制:高速信号线上用于高频噪声抑制(注意电流与 DCR 限制)。
  • 高频测试与实验板:短连线、高频滤波与谐振电路实验验证元件。

示例参数计算:在 300 MHz 时理想感抗 XL = 2πfL ≈ 2π×300e6×47e-9 ≈ 88.6 Ω;在频率接近 SRF(1.3 GHz)附近,器件会出现并联谐振行为并逐渐转为电容性响应,因此实际工作频率应低于 SRF 以保持电感性特征。

四、设计与选型建议

  • 频率范围:建议在 SRF 以下使用(通常比 SRF 低 2–3 倍能获得稳健的电感性行为),在接近 SRF 时应验证电路响应。
  • 功率与发热:以额定电流 100 mA 计算,最大直流功耗 P = I^2·DCR ≈ 0.1^2×3.6 ≈ 36 mW,器件 DCR 较大时在持续直流或低频大电流场合会产生较明显的压降与发热,必要时应降低工作电流或更换大电流型号。
  • 器件并联/串联:若需提高电流承载或降低等效 DCR,请优先采用型号规格更高的组件;并联多个 0201 小电感会改变等效电感值并带来布局复杂性,需在仿真与测量后确认。
  • 布局建议:尽量缩短与地/信号引线的走线长度,避免在高频信号旁产生额外寄生电感或耦合。贴片朝向与焊盘布局按厂商推荐的 land pattern 设计,保证焊接可靠性与电气性能。

五、焊接与可靠性注意事项

  • 回流焊工艺:可采用无铅回流焊(参考 JEDEC/J-STD-020 曲线),避免超出厂商推荐的最高回流温度和时间。
  • 机械应力:0201 封装极小,避免在贴装、测试或外力作用下产生过大机械应力,以防断裂或性能退化。
  • 清洗与助焊剂:推荐使用与器件兼容的无清洗或低残留助焊剂,避免腐蚀或残余导致长期可靠性问题。

六、测试与验证要点

  • 高频参数测量:用矢量网络分析仪(VNA)测量 S 参数以确定实际频率响应、插损与谐振点;在目标频段测量 Q、等效串联电阻(ESR)和 SRF。
  • DCR 与电流测试:用精密电阻表或四线测量确认 DCR,并在实际电流工况下测量电压降与温升,验证实际功耗。
  • 环境与寿命试验:在温度循环、湿热、振动等可靠性试验中验证焊点与电感性能稳定性。

七、包装与采购建议

  • 该型号通常以卷带(tape & reel)方式供应,适用于自动贴装。
  • 在选型过程中,若电流或 DCR 要求更严格,可向村田查询相近封装但不同规格的电感系列以做替代。
  • 采购时请确认批次、封装版本与完整的规格书(datasheet),并在量产前进行基于自身电路的样品验证。

总结:LQP03TN47NH02D 为 muRata 提供的一款适用于中高频应用的 0201 厚膜片式电感,具备高频良好特性与极小封装优势,但在直流电阻与电流承载方面需在设计期给予充分考虑与验证,确保在目标应用中性能与可靠性满足要求。

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.
