FH风华VHF100505HQ82NJT 贴片叠层高频电感产品概述

一、产品定位与核心特性

FH风华VHF100505HQ82NJT是一款针对甚高频(VHF)频段优化的0402封装贴片叠层电感,聚焦小型化射频电路的高频性能需求,兼顾电流承载能力与能量损耗控制,适配消费电子、汽车电子等领域的中低功耗模块设计。其核心优势在于小体积集成、高频Q值稳定及批量参数一致性,可替代传统绕线电感实现更紧凑的PCB布局。

二、关键电气参数详解

该电感的电气参数经过精准校准,满足射频电路对电感性能的严格要求:

  • 电感值:标称82nH,精度±5%,覆盖工业级射频匹配、滤波等常规场景,批次间偏差极小;
  • 额定电流:500mA(直流叠加电流),可有效抑制工作电流下的磁饱和现象,保证电感值稳定不漂移;
  • 直流电阻(DCR):240mΩ,低电阻设计显著降低功耗与发热,提升模块整体效率(尤其适合低功耗设备);
  • 品质因数(Q值):8@100MHz,高Q值意味着高频下能量损耗低,信号完整性表现优异,可减少射频链路的噪声干扰;
  • 自谐振频率(SRF):750MHz,谐振点远高于VHF频段(30~300MHz)上限,避免工作频段内的谐振损耗,保证射频性能稳定。

三、物理结构与封装优势

VHF100505HQ82NJT采用叠层陶瓷结构(多层陶瓷介质+内电极叠合成型),相比传统绕线电感具有明显优势:

  • 体积紧凑:0402封装(尺寸约1.0mm×0.5mm×0.5mm),适配蓝牙耳机、智能手环等小型化设备的高密度PCB布局;
  • 一致性优异:叠层工艺避免绕线电感的匝数误差,电感值、Q值等参数一致性达±2%以内,适合批量生产;
  • 抗环境干扰:陶瓷介质耐温、抗振动性能优于绕线电感,可应用于车载、工业控制等振动环境;
  • 贴片式设计:兼容自动化SMT生产,焊接效率高,且无引线寄生电感,提升射频电路的匹配精度。

四、典型应用场景

基于高频性能与小体积优势,该电感主要应用于以下场景:

  1. 消费电子射频模块:蓝牙(BLE)、WiFi(2.4G频段辅助匹配)、2G/3G移动通信终端的射频前端滤波/匹配电路;
  2. 汽车电子:胎压监测系统(TPMS)、车载蓝牙模块的信号耦合/滤波电感;
  3. 无线传感器网络:低功耗无线节点(如智能安防、环境监测)的射频收发电路;
  4. 小型通信设备:对讲机、儿童手表的VHF频段射频模块电感匹配。

五、可靠性与质量保障

作为风华电子(FH)的成熟产品,VHF100505HQ82NJT具备可靠的质量体系:

  • 品牌背书:风华是国内被动元件龙头企业,产品符合IEC、JIS等国际标准,通过ISO9001质量认证;
  • 环保合规:符合RoHS 2.0、REACH标准,无铅无镉,满足全球市场环保要求;
  • 宽温耐候:工作温度范围-40℃~+85℃,抗温湿度变化能力强,可适应不同地域环境;
  • 批量稳定性:每批次产品经全参数测试,性能差异极小,降低终端厂商的测试与筛选成本。

六、选型与使用注意事项

为保证电感性能稳定,使用时需注意以下要点:

  1. 电流限制:工作直流电流不得超过500mA,避免磁饱和导致电感值下降(可通过串联电阻或降额设计保障);
  2. 频率匹配:工作频率需远离自谐振频率750MHz(建议工作在30~500MHz范围内),避免谐振损耗;
  3. PCB布局:尽量靠近射频芯片放置,走线宽度≤0.2mm,减少寄生电感与信号串扰;
  4. 焊接规范:遵循0402封装回流焊工艺(峰值温度≤260℃,时间≤10秒),避免过热损坏陶瓷叠层结构。

该电感凭借高频性能、小体积与可靠性,成为VHF频段射频电路的高性价比选型,可满足消费电子、汽车电子等领域的批量应用需求。

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.
