CGA0402C0G820J500GT 陶瓷电容产品概述

CGA0402C0G820J500GT是国内知名陶瓷电容厂商HRE(芯声)推出的高频高稳定多层陶瓷电容(MLCC),针对温度稳定性、信号损耗要求严苛的电路场景设计,核心参数覆盖容值82pF、精度±5%、额定电压50V,采用0402小型化封装,是消费电子、射频通信、工业控制等领域的常用基础元件。

1. 产品核心身份与定位

该产品属于HRE的C0G(NP0)系列陶瓷电容——这一系列以“近零温度漂移”为核心特点,区别于X7R、Y5V等温度系数电容,主要定位为高稳定信号链路的关键匹配元件,适用于需要容值随温度/电压变化极小的场景,如射频滤波、时钟晶振负载、PLL环路滤波等。

2. 关键参数与性能特点

2.1 容值与精度

  • 标称容值:82pF(由代码“820”定义,即82×10⁰);
  • 精度等级:J档(±5%),批量生产一致性好,可直接用于需要准确容值匹配的电路(如晶振负载电容),无需额外筛选;
  • 容值稳定性:无直流偏置效应(C0G材质典型特性),当电压在0~50V范围内变化时,容值变化率≤±0.1%,远优于X7R材质的偏置衰减。

2.2 温度系数与温宽

  • 温度系数:C0G(NP0),≤±30ppm/℃(行业标准);
  • 工作温度范围:-55℃~125℃,覆盖工业级、消费电子的宽温需求;
  • 温漂实测:在全温宽内,容值变化量≤±0.025pF(以82pF标称值计算),对高频信号的相位、频率影响可忽略。

2.3 高频与损耗特性

  • 介电常数:约30(C0G材质典型值),介电损耗低(DF≤0.15%,1kHz/1Vrms测试条件);
  • 高频截止频率:约10GHz(基于0402封装的寄生参数估算),适合2.4GHz、5GHz等主流射频频段应用;
  • 谐振特性:自谐振频率(SRF)约2GHz(100pF以下0402封装典型值),在非谐振频段内表现为纯电容特性,无寄生电感干扰。

3. 封装与工艺优势

3.1 0402小型化封装

  • 尺寸:英制0402(对应公制1005),具体为0.04英寸(1.0mm)长×0.02英寸(0.5mm)宽×0.02英寸(0.5mm)厚;
  • 优势:适合高密度PCB设计,如智能手机主板、可穿戴设备、小型化模块(蓝牙/WiFi模块),大幅节省电路板空间。

3.2 制造工艺

  • 介质材料:高纯度钛酸钡基陶瓷,颗粒度均匀(≤1μm),确保介电性能稳定;
  • 电极工艺:内电极采用镍(Ni),外电极采用镍锡(Ni/Sn)镀层,兼容无铅焊接工艺,焊接后剪切强度≥1.5N(行业标准);
  • 叠层精度:每层介质厚度≤5μm,叠层偏差≤±1μm,确保容值一致性(批量容值分布集中在±2%以内)。

4. 典型应用场景

该产品凭借高稳定、低损耗、小型化特点,广泛应用于以下领域:

  1. 射频通信:基站RRU的滤波电路、路由器/交换机的射频前端耦合电容、蓝牙5.0/WiFi 6模块的谐振电容;
  2. 时钟与晶振:智能手机的TCXO负载电容、工业PLC的PLL环路滤波电容;
  3. 消费电子:平板电脑的电源滤波电容、智能手表的射频信号耦合电容;
  4. 工业控制:传感器模块的信号调理电容、PLC的输入输出滤波电容。

5. 可靠性与环境适应性

  • 可靠性测试:符合IEC 60384-1、GB/T 2693-2001等标准,通过高温存储(125℃/1000h)、湿度循环(85℃/85%RH/1000h)、振动(10g~2000Hz)、冲击(1000m/s²)等测试,无失效;
  • 环保特性:符合RoHS 2.0、REACH法规,无铅无镉,满足绿色制造要求。

6. 品牌与品质保障

HRE(芯声)是国内专注MLCC研发生产10余年的厂商,拥有多条自动化生产线,年产能超100亿只。该产品具备以下品质优势:

  • 一致性管控:批量生产中,容值、温度系数等参数离散度≤±1%,减少电路调试工作量;
  • 供应稳定性:产能稳定,可满足中小批量(月需10万只)到大规模(月需1000万只)需求;
  • 售后支持:提供技术文档、样品测试,针对特殊应用可定制参数(如更高精度)。

总结

CGA0402C0G820J500GT以C0G材质的近零温漂、低损耗为核心竞争力,结合0402小型化封装的高密度优势,成为高频、高稳定电路设计的“刚需元件”。其广泛的应用场景、可靠的环境适应性以及HRE的品质保障,使其在消费电子、通信、工业等领域得到持续认可。

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
