CLH1005T-3N9S-S 产品概述

一、概述

CLH1005T-3N9S-S 是 chilisin(奇力新)推出的一款贴片叠层电感,0402 尺寸(对应业界 1005 公制),名义电感值 3.9 nH。该器件针对小尺寸、高频应用优化,直流电阻为 180 mΩ,品质因数 Q=8(100 MHz),自谐振频率(SRF)约 6.1 GHz,额定直流电流 400 mA。结构紧凑,适合空间受限的表贴板级设计。

二、主要电气特性与意义

  • 电感值:3.9 nH,适合射频匹配、移相、谐振和阻抗补偿等高频场合。
  • 直流电阻(DCR):≈180 mΩ,表示直流损耗,影响直流通流能力与功耗。
  • 品质因数(Q):8@100 MHz,表明在 100 MHz 附近器件有中等选择性与损耗表现,适合需要一定 Q 值但不强调极高 Q 的电路。
  • 自谐振频率(SRF):6.1 GHz,器件在 SRF 以下表现为电感性,超过 SRF 后行为趋向电容性,因此在选型时应保证工作频段低于 SRF。
  • 额定电流:400 mA,表示在该电流下器件能维持标称性能且不过度温升或磁饱和。

三、典型应用场景

  • 射频前端:阻抗匹配、谐振回路与阻容耦合网络等。
  • 高频滤波器:作为带通或带阻滤波器单元,尤其在 GHz 级频段附近表现稳定。
  • 信号调谐与串联阻抗:用于高速数字线或射频线路的串联补偿与移相设计。
  • EMI/噪声抑制:配合电容用于高频噪声抑制和去耦,适用于移动终端、无线模块与射频子系统。

四、封装与工艺要点

0402 小型化封装便于高密度布板,但对焊接、回流曲线和贴装定位要求较高。推荐采用标准回流焊工艺,避免手工过热或机械应力(如强烈刮擦、弯折)对器件造成破坏。板上布局时应保证焊盘尺寸与厂方推荐一致,以确保良好焊接与热散。

五、布局与使用建议

  • 将电感尽量靠近需要的端点(如滤波器输入/输出或射频器件引脚)以减小走线寄生。
  • 在高频运行时,建议验证器件在实际布局下的等效阻抗(S 参数),因为走线和邻近元件会改变实际响应。
  • 对于接近额定电流的应用,应留有裕度,关注温升和可能的磁饱和效应;必要时选用更大电流等级或更低 DCR 的型号。
  • 在多层板上合理利用地平面以改善接地并降低辐射。

六、测试与质量确认

在最终设计中,应通过网络分析仪测量器件在目标频段的 L、Q 与 S11/S21,以确认实际工作点的性能。直流电阻可用微欧表或四线制测量确认。若设计对长期稳定性或高温特性敏感,应进行温度循环与老化测试。

七、选型注意事项与替代方案

在选型时,若系统要求更高 Q、更大电流或更低 DCR,可考虑同系列或其他型号的同类叠层电感作为替代。设计评估时优先对比 SRF、DCR 与额定电流三项关键指标,确保在目标工作频段和电流条件下满足性能与可靠性要求。

如需更详细的封装尺寸图、回流曲线或典型等效电路图,可参考厂商数据手册或联系供应商获取样片与测试报告。

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.

Replenishment inquiry Typical RFQ workflow
