CGA0402C0G2R2C500GT 多层陶瓷电容器产品概述

一、产品核心定位与设计目标

CGA0402C0G2R2C500GT是HRE芯声推出的高频稳定型多层陶瓷电容器(MLCC),针对高密度集成、高频电路对容值稳定性的严苛需求设计。其核心定位为小体积(0402封装)、宽温稳定(C0G温度系数)、高可靠性的通用型电容,适用于通信、消费电子、工业控制等多领域的高频滤波、耦合及谐振电路。

二、关键参数与性能特性

该产品的核心参数及性能优势如下:

  1. 容值与精度:标称容值2.2pF,容差典型值±5%(符合C0G介电材料的高精度特性),无容值老化现象(Class 1陶瓷电容固有特性);
  2. 额定电压:直流额定电压50V,交流应用需按降额规则(交流峰值电压不超过额定直流电压的70%);
  3. 温度稳定性:采用EIA Class 1(C0G)介电材料,温度系数为±30ppm/℃(-55℃~125℃范围内),容值随温度变化极小,满足射频电路对容值稳定的核心要求;
  4. 高频特性:低损耗角正切(tanδ≤0.15%@1kHz),适合1GHz以上射频电路的信号传输,无明显信号衰减;
  5. 封装规格:0402英寸封装(对应公制1005,尺寸1.0mm×0.5mm×0.5mm),兼容标准SMT贴装工艺,适配高密度PCB设计;
  6. 环保与可靠性:符合RoHS 2.0及无铅焊接要求,端电极采用银-镍-锡三层结构,耐焊接热(260℃回流焊10秒内无失效),机械强度满足IEC 60068-2-21弯折测试标准。

三、封装与可靠性设计细节

  1. 端电极结构:三层复合电极设计——内层银层保证电导率,中间镍层阻隔银迁移(避免长期使用后性能下降),外层锡层提升焊接兼容性,减少虚焊/冷焊风险;
  2. 陶瓷介质:采用高纯度钛酸钡基C0G陶瓷,晶粒致密性高,漏电流典型值≤10nA(25℃、50V条件下),抗潮湿能力强;
  3. 机械防护:封装边缘采用圆角设计,减少贴装时的应力集中,抗弯折半径≥2mm,适配振动场景(如车载电子);
  4. 温度适应性:工作温度范围-55℃125℃,存储温度-40℃85℃,覆盖工业级及大部分汽车电子(非高温严苛场景)的温度需求。

四、典型应用领域

  1. 通信设备:WiFi 6/6E模块、蓝牙5.0/5.2射频前端的滤波/耦合电容,5G小基站中频电路;
  2. 消费电子:智能手机GPS/NFC模块、智能穿戴设备高频信号调理电路;
  3. 工业控制:PLC、伺服驱动器电源滤波,传感器信号耦合电路;
  4. 医疗设备:便携式监护仪、血糖仪高频电路(对容值稳定要求高的信号采集模块);
  5. 汽车电子:车载信息娱乐系统(IVI)蓝牙/WiFi模块(若为车规认证版本,可扩展至ADAS传感器辅助电路)。

五、选型与替换参考

若需替换该产品,需保证以下参数一致:

  • 封装:0402(1005公制);
  • 温度系数:C0G(Class 1);
  • 容值:2.2pF±5%;
  • 额定电压:50V DC;
  • 端电极:无铅(Sn/Pb除外)。

常用替换型号:

  • 村田:GRM1555C1H2R2CA02D;
  • TDK:C1005C0G2R2C500;
  • 三星:CL05B2R2CB5NNNC。

注意:若应用场景需车规认证(如AEC-Q200),需选择对应车规版本,普通版本不建议用于汽车动力系统等严苛场景。

该产品以高性价比、稳定性能适配中高端电子设备的高频设计需求,是0402封装C0G电容的主流选型之一。

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
