HVU202B变容二极管产品概述

HVU202B是SHIKUES(时科)推出的一款独立式变容二极管,针对射频调谐、信号滤波等高频电路场景优化设计,具备低漏电流、宽温适应性、稳定电容特性等核心优势,适配消费电子、汽车电子及工业控制等多领域应用。

一、产品定位与核心应用场景

HVU202B定位于中低压高频调谐元件,核心用于需要精确电容调谐的电路模块,典型应用包括:

  • 便携式电子设备:蓝牙/WiFi射频前端、FM收音机调谐电路(适配低功耗电池供电需求);
  • 汽车电子:车载通信模块、低频信号调谐单元(满足-55℃至+100℃宽温环境);
  • 工业控制:信号滤波电路、传感器前端调谐(适应高低温及高可靠性要求);
  • 小型通信终端:无线耳机、物联网节点的射频调谐模块(小封装适配高密度布局)。

二、关键电气参数详解

HVU202B的核心参数平衡了调谐性能与可靠性,关键指标如下:

  1. 反向耐压与漏电流:直流反向耐压(Vr)28V,满足多数射频调谐电路的偏置电压需求;反向电流(Ir)仅10nA@28V,低漏电流可显著降低电路功耗,减少信号干扰,尤其适合便携设备。
  2. 电容特性:标称电容(CT)17pF,匹配常见调谐电路容值范围;电容比6.2@C1V/C4V,1V至4V偏置电压下电容变化可预测且稳定,无需复杂补偿电路即可实现精确频率调谐。
  3. 串联电阻与损耗:串联电阻(Rs)低至450mΩ,有效降低高频信号传输损耗,提升电路效率,避免电阻发热导致的性能衰减。
  4. 宽温适应性:工作结温覆盖-55℃至+100℃,可适应北方户外低温、汽车仪表盘高温等复杂场景,可靠性符合工业级标准。

三、封装形式与可靠性设计

HVU202B采用SOD-323表面贴装封装(尺寸1.6mm×0.8mm),具备以下优势:

  • 体积紧凑:适配小型化电子设备的高密度布局,如无线耳机、智能手表等终端;
  • 独立式配置:无内部并联/串联元件,电路设计灵活性高,可按需组合使用;
  • 可靠性保障:封装符合RoHS标准,耐振动、耐冲击性能优异,长期工作无参数漂移,适合批量生产。

四、品牌与技术优势

SHIKUES(时科)作为半导体元器件专业品牌,HVU202B继承了其核心技术优势:

  • 一致性优异:批量生产参数偏差≤±5%,同一批次产品电容、漏电流等指标稳定,便于电路调试;
  • 成本效益平衡:优化封装与制造工艺,在保证性能的前提下控制成本,适配中低端至中高端产品需求;
  • 技术支持完善:提供调谐电路参考方案,帮助客户快速完成开发与验证。

五、应用注意事项

使用HVU202B需注意:

  • 偏置电压不超过28V,避免反向击穿;
  • 焊接温度控制在260℃以内(符合SOD-323封装规范);
  • 高功率射频电路中需预留散热空间,避免结温超过100℃。

综上,HVU202B凭借稳定的电容特性、低功耗、宽温适应性及小型化封装,成为射频调谐领域的高性价比选择,可满足多场景下的精确电容调谐需求。

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
