VHF060303HQ4N7BT02 高频叠层贴片电感产品概述

一、产品定位与核心属性

VHF060303HQ4N7BT02是风华电子(FH) 推出的高频专用叠层贴片电感,针对VHF(30MHz)至UHF(3GHz)频段的小功率射频电路设计,核心聚焦「小封装、高Q值、低损耗」三大特性,适配智能便携设备的高密度PCB布局与低功耗通信需求。

二、关键参数深度解析

  1. 电感值与精度:标称电感值4.7nH,叠层工艺保证电感值一致性(典型偏差±5%),满足射频电路对精准阻抗匹配的要求,避免信号反射损耗;
  2. 电流承载能力:额定直流电流300mA,此电流下电感值变化率≤10%(风华叠层电感典型规格),可有效避免大电流导致的磁饱和,保障电路稳定;
  3. 直流电阻(DCR):450mΩ低阻设计,大幅降低直流功耗,提升低功耗设备(如蓝牙手环、无线传感器)的电池续航能力;
  4. 品质因数(Q值):14@500MHz(Q=2πfL/DCR),高Q值意味着目标频段内能量损耗极小,是谐振电路、阻抗匹配网络的核心优势;
  5. 自谐振频率(SRF):6.2GHz,远高于常用工作频段(≤3GHz),实际使用中无「电感转电容」的寄生效应干扰,性能稳定可靠。

三、封装与结构优势

  1. 小尺寸封装:采用0201英制贴片封装(对应公制0603),尺寸仅0.6mm×0.3mm,可显著减少PCB占用面积,适配智能手环、蓝牙耳机等便携设备的高密度布局;
  2. 叠层结构设计:相比传统绕线电感,叠层工艺大幅降低寄生电容与电感,提升高频响应速度;同时一致性更好,批量生产中参数波动极小;
  3. 贴片兼容性:符合回流焊工艺标准,可直接集成于SMT生产线,生产效率高,焊接不良率控制在0.1%以内(风华行业标准)。

四、典型应用场景

  1. 蓝牙/WiFi射频模块:用于发射端的LC谐振匹配电路,在2.4GHz频段下(SRF6.2GHz覆盖该范围)提供稳定的阻抗变换,减少信号反射损耗;
  2. 无线传感器网络(WSN):低功耗节点的接收滤波电路,4.7nH电感配合电容实现带通滤波,抑制杂波干扰,保障数据传输可靠性;
  3. FM收音机与对讲机:中高频段(88MHz~1GHz)的调谐电路,高Q值保证收音灵敏度与音质,提升用户体验;
  4. 小型通信设备:如智能门锁、智能家居遥控器的射频收发电路,满足小电流(≤300mA)、小体积的设计需求。

五、可靠性与品牌保障

  1. 品牌背书:风华电子作为国内电感行业龙头,产品通过ISO9001、RoHS、REACH等认证,一致性与可靠性经10年以上市场验证;
  2. 环境适应性:工作温度范围-40℃~+85℃,符合工业级(如车载射频)与消费级设备的环境要求;
  3. 振动与冲击耐受:通过IEC 60068-2-6振动测试(10~2000Hz,1g加速度),可承受便携设备的日常跌落与振动。

六、选型与使用注意事项

  1. 电流限制:实际工作直流电流需≤300mA,若超过可能导致电感饱和,性能急剧下降;
  2. 频率范围:建议工作频率≤5GHz(远低于SRF6.2GHz),避免接近自谐振点影响性能;
  3. 焊盘设计:PCB焊盘需符合0201封装标准(推荐焊盘尺寸0.3mm×0.4mm),避免虚焊或短路;
  4. 应用匹配:高Q值电感适合谐振与匹配,若用于大电流滤波需选择额定电流更大的型号(如风华1008系列)。

该产品凭借小体积、高Q值、低损耗的综合优势,成为射频电路设计中「小功率高频场景」的优选电感之一。

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
