FH风华VHF100505HQ2N2BT贴片叠层电感产品概述

一、产品基本识别信息

该产品为风华高科(FH) 推出的高频贴片叠层电感,型号为VHF100505HQ2N2BT,核心特征如下:

  • 封装规格:英制0402(对应公制1.0mm×0.5mm×0.5mm,标准贴片高度),适配常规SMT自动化贴装;
  • 产品类型:叠层高频电感,采用陶瓷基片叠层工艺,无外露引线设计;
  • 标称电感值:2.2nH(射频电路常用匹配电感值)。

二、核心电性能参数及应用意义

产品关键参数明确了其适用场景,各参数的实际价值如下:

  1. 电感值(2.2nH):射频电路阻抗匹配、LC滤波、振荡器反馈网络的典型取值,覆盖蓝牙、WiFi、NFC等主流无线频段的匹配需求;
  2. 额定电流(900mA):工作时允许的最大直流电流(或交流峰值电流),满足多数射频模块(如蓝牙5.0、车联网T-Box)的电流需求,无需并联电感即可实现目标功能;
  3. 直流电阻(DCR:90mΩ):直流下的串联电阻,数值较低意味着电流通过时功耗小(计算功耗:(I^2R=0.9^2×0.09≈0.073W)),发热低,可靠性更高;
  4. 品质因数(Q值:8@100MHz):电感储能与损耗的比值,Q值越高则高频下信号损耗越小。该产品在100MHz频段Q值达8,适合射频前端的低损耗匹配;
  5. 自谐振频率(SRF:6GHz):超过此频率电感将呈容性,因此适用频段覆盖甚高频(VHF:30-300MHz)、特高频(UHF:300MHz-3GHz)及部分超高频(SHF:3-6GHz)低频段,适配5G sub-6GHz、WiFi 6E等新兴频段。

三、结构与工艺特点

该产品采用风华成熟的叠层陶瓷工艺,核心优势体现在:

  • 寄生参数极小:无引线叠层结构减少了寄生电感和电容,提升高频响应速度,避免信号失真;
  • 一致性优异:批量生产时电感值偏差控制在±5%以内(常规叠层电感标准),适合量产设备的一致性要求;
  • 耐环境性能:陶瓷基片耐高温、耐湿度,可通过常规回流焊工艺(峰值温度240-260℃,时间≤10秒),符合汽车电子、工业级设备的可靠性要求;
  • 小型化适配:0402封装仅为指甲盖的1/20大小,适配智能手机、智能穿戴、物联网模块等高密度PCB设计。

四、典型应用场景

结合参数特性,该产品主要用于以下高频电路:

  1. 无线通信模块:蓝牙(2.4GHz)、WiFi(2.4G/5G/6G)、NFC(13.56MHz)的天线匹配网络、射频前端滤波;
  2. 车载电子:车联网T-Box、车载蓝牙、无线充电的高频电路匹配;
  3. 消费电子:智能手机射频放大器、智能手表NFC线圈匹配、无线耳机蓝牙模块;
  4. 工业物联网:低功耗蓝牙(BLE)模块、LoRa网关的射频匹配网络;
  5. 射频测试设备:信号发生器、频谱分析仪的阻抗匹配组件。

五、选型与使用注意事项

  1. 频段匹配:避免在6GHz以上频段使用(此时电感呈容性,无法实现感性功能);
  2. 电流限制:工作电流不得超过900mA,否则可能导致电感饱和,电感值下降、损耗增加;
  3. 贴装工艺:回流焊温度曲线需符合风华电感要求,焊接后需检查焊点无虚焊、假焊;
  4. 布局设计:高频电路中需缩短电感与射频元件的走线长度,避免寄生耦合影响信号完整性;
  5. 储存条件:需在干燥环境(湿度≤60%)下储存,避免长期暴露在高湿度环境中导致性能下降。

六、产品优势总结

相较于同封装绕线电感,该叠层电感具备三大核心优势:

  • 高频性能更优:Q值更高、SRF覆盖更广,适合5G等新兴频段;
  • 可靠性更高:叠层工艺无引线断裂风险,耐温耐湿性能优于绕线电感;
  • 成本可控:批量应用时性价比高,适合中大规模量产设备。

该产品是射频电路小型化、高频化的优选电感元件,可满足多数消费电子、车载及工业物联网的高频匹配需求。

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.
