VHF100505HQ33NJT 叠层高频电感产品概述

VHF100505HQ33NJT是风华高科(FH品牌)推出的0402封装叠层高频贴片电感,专为VHF(甚高频)及部分UHF(特高频)频段的射频、通信电路设计,兼具小型化、高Q值与稳定性能,适配便携电子设备的高密度集成需求。

一、产品基本信息

该电感的核心基础信息如下:

  • 产品型号:VHF100505HQ33NJT
  • 品牌:风华高科(FH)
  • 封装形式:0402(英制尺寸,对应公制1005,规格为1.0mm×0.5mm)
  • 产品类型:叠层高频贴片电感
  • 命名逻辑:型号中“VHF”为风华高频电感系列标识,“100505”对应封装尺寸(1005为长/宽,05为厚度),“HQ”表示高频优化设计,“33N”代表电感值33nH,“JT”为精度与封装补充标识。

二、核心电性能参数详解

该电感针对高频应用优化的关键参数如下:

  1. 电感值与精度:33nH ±5%
    电感量精准控制在33nH,±5%精度覆盖大多数射频电路的误差要求,避免因电感偏差导致信号失真或匹配失效。
  2. 额定电流:250mA(25℃环境下)
    指额定温度下允许持续通过的最大直流电流,超此值可能导致磁芯饱和、电感量下降甚至器件损坏,实际应用需预留温度余量。
  3. 直流电阻(DCR):典型值1Ω
    反映线圈直流损耗,低DCR可减少电路功耗、降低发热,提升设备能效与可靠性。
  4. 品质因数(Q值):8@100MHz
    Q值=2πfL/R(f为工作频率),代表电感储能与损耗之比。8的Q值在0402封装中属优异水平,有效减少信号损耗。
  5. 自谐振频率(SRF):1.3GHz
    电感寄生电容与电感量的谐振频率,低于SRF呈感性、高于呈容性。1.3GHz覆盖VHF(30-300MHz)至部分UHF频段,适用范围广。

三、结构与工艺特性

采用叠层陶瓷工艺,相比绕线电感具备明显优势:

  • 叠层陶瓷结构:线圈印刷于多层陶瓷基片,高温烧结一体化成型,体积小、一致性好,无绕线松动风险;
  • 高频优化设计:优化线圈匝数与陶瓷介电常数,降低寄生电容与高频损耗,提升Q值与SRF;
  • 高可靠性封装:符合IPC-J-STD-020标准,耐受回流焊峰值260℃,抗振动(10G)、抗冲击(50G)达工业级要求;
  • 环保合规:符合RoHS、REACH指令,无铅无卤,满足全球市场环保要求。

四、典型应用场景

适配以下高频电路与设备:

  1. 射频通信:FM收音机(88-108MHz)、对讲机(VHF136-174MHz)、WLAN 2.4GHz以下模块;
  2. 便携电子:智能手机、智能穿戴(手表)、无线耳机的射频前端与蓝牙模块;
  3. 高频滤波:电源滤波(抑制开关噪声)、信号滤波(滤除射频杂波);
  4. 谐振与匹配:LC谐振回路(振荡器、选频网络)、射频阻抗匹配(提升信号传输效率);
  5. 工业控制:小型化无线模块(ZigBee)的高频部分。

五、选型适配优势

相比同类产品,具备以下优势:

  1. 小型化集成:0402封装体积仅1.0mm×0.5mm,适配高密度PCB设计,满足便携设备轻薄化需求;
  2. 性能平衡:小封装下实现33nH电感量、±5%精度与8@100MHz Q值,无需在性能与体积间妥协;
  3. 品牌可靠性:风华高科被动元件龙头,产品一致性好、批量供货稳定,售后完善;
  4. 成本效益:叠层工艺比绕线电感成本低,适合大规模量产,降低终端BOM成本。

VHF100505HQ33NJT凭借小型化、高Q值与稳定性能,成为VHF/UHF频段射频电路的理想选择,广泛应用于通信、消费电子、工业控制等领域。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
