CGA0402C0G680J500GT 多层陶瓷电容产品概述

一、核心参数解析

CGA0402C0G680J500GT是HRE(芯声)针对高精度、高稳定性场景设计的NP0类多层陶瓷电容(MLCC),核心参数可支撑多数中低压、高频电路的核心需求:

  • 容值与精度:标称容值68pF,采用行业通用的三位标识法(“680”)——前两位“68”为有效数字,第三位“0”为倍率(10⁰),实际容值为68×10⁰=68pF;精度等级为“J”(对应±5%),生产中通过高精度叠层印刷工艺控制,容值离散性仅为常规电容的1/3左右,可满足信号调理、滤波等对容值一致性要求高的场景。
  • 额定电压:直流额定电压50V,覆盖5V、12V、24V等主流中低压系统,无需额外降额即可稳定工作,同时具备1.5倍额定电压的短时过压能力(符合IEC 61000-4-5浪涌标准)。
  • 温度系数:采用C0G材质(IEC分类),属于NP0(负-正-零)陶瓷,温度系数≤±30ppm/℃,在-55℃至125℃的宽温范围内,容值变化率≤±0.3%——这是其区别于X7R等温漂电容的核心优势,可避免温度波动导致的电路参数偏移。
  • 封装标识:型号中“0402”为英制封装尺寸,对应公制1005(1.0mm×0.5mm),厚度仅0.5mm左右,适合手机、路由器等小型化、高密度贴装设计。

二、封装与制造工艺

该产品采用表面贴装(SMT)兼容的0402封装,制造工艺围绕“小型化+高可靠性”优化:

  • 封装结构:采用多层陶瓷叠层(MLCC)技术,内部电极采用银钯合金(Ag-Pd),端电极采用无铅锡(Sn)镀层,符合RoHS 2.0、REACH及无卤素要求,可直接用于环保型电子产品。
  • 工艺细节:电极印刷精度控制在±2μm以内,叠层错位率≤1μm,确保容值一致性;端电极采用“三层镀层”(镍+锡),提升焊接附着力,回流焊温度范围(220℃~260℃)兼容主流SMT生产线,焊接不良率≤0.05%。
  • 体积优势:0402封装体积仅为0603封装的1/4,可大幅降低电路板面积,尤其适合可穿戴设备、5G射频模块等对空间敏感的场景。

三、电气性能特点

C0G材质的固有特性赋予该产品低损耗、高频率稳定性,具体表现为:

  • 低损耗因子(DF):典型值≤0.15%@1kHz,远低于X7R电容(典型DF≥1%),可减少高频信号的能量衰减,适合射频、微波电路的信号传输。
  • 高谐振频率:68pF容值下,谐振频率典型值≥10GHz,可覆盖5G Sub-6GHz、毫米波等频段,避免电容在工作频率下进入谐振区导致性能下降。
  • 直流偏置稳定性:在额定电压内,容值随直流偏置的变化率≤±0.2%(@25℃),可稳定用于电源去耦、电压调节器等带直流偏置的电路。

四、典型应用领域

基于上述性能,该产品主要应用于对精度、稳定性要求苛刻的场景:

  1. 射频通信设备:5G基站滤波器、手机射频前端(PA匹配网络、振荡器)——C0G的温度稳定性可避免滤波器中心频率偏移,保障信号质量;
  2. 高速数字电路:服务器、路由器的时钟去耦、信号滤波——低损耗减少信号上升沿衰减,提升10Gbps以上高速信号的传输速率;
  3. 医疗电子:便携式监护仪、超声设备的信号调理电路——宽温范围的容值稳定,可保障极端环境下(如低温手术室)的测量准确性;
  4. 工业控制:PLC、传感器模块的模拟信号滤波——耐温性能满足-40℃~85℃的工业现场需求;
  5. 汽车电子:车载信息娱乐系统的射频子模块(可选AEC-Q200认证批次)——满足汽车级可靠性要求。

五、品牌与可靠性保障

HRE(芯声)作为国内MLCC领域的专业化厂商,对该产品的可靠性做了多重保障:

  • 质量控制:每批次经过125℃×1000h高温老化、-55℃~125℃×1000次温度循环测试,不良率≤0.1%;
  • 认证支持:标准批次符合RoHS、REACH,部分批次可提供AEC-Q200汽车级认证,满足不同行业需求;
  • 供货能力:年产能稳定在5亿只以上,封装一致性好,支持小批量(1000只起)定制与大批量(百万级)供应,可匹配客户的研发与量产节奏。

综上,CGA0402C0G680J500GT通过C0G材质的核心优势,结合小型化封装与高可靠性设计,成为高精度电路的理想选择,尤其适合5G、医疗、工业等对稳定性要求高的领域。

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.
