CGA0402C0G9R0C500GT 多层陶瓷电容器产品概述

CGA0402C0G9R0C500GT是HRE(芯声)针对高频稳定场景推出的一款高频低损耗多层陶瓷电容器(MLCC),核心定位为满足电路对容值一致性、温度稳定性及小型化的严苛要求,广泛适配消费电子、通信等领域的信号处理需求。以下从多维度展开详细概述:

一、产品基本信息

该产品型号各部分含义清晰,对应核心参数与应用特性:

  • CGA:HRE高频MLCC系列标识,聚焦射频/精密滤波场景;
  • 0402:英制封装尺寸(公制1005),实际尺寸为1.0mm×0.5mm×0.5mm(长×宽×厚);
  • C0G:温度系数类别(IEC NP0标准),代表最优温度稳定性;
  • 9R0:标称容值9pF,属于小容值高频电容范畴;
  • C500:直流额定电压50V,适配中低功率电路;
  • GT:包装后缀(12mm卷装,适合自动化贴装)。

产品类型为高频稳定型MLCC,区别于普通X7R/X5R介质电容,重点解决高频下容值漂移、损耗大的问题。

二、核心参数深度解析

1. 容值与精度

标称容值9pF,标准精度±5%(可定制±1%),批次间容值差异≤±0.1pF——这一指标优于行业平均水平(±0.2pF),确保电路参数的可重复性,避免因电容偏差导致射频性能波动。

2. 温度系数C0G(NP0)

C0G是MLCC中温度稳定性最优的介质,核心特性:

  • 温度范围:-55℃~125℃(工业级宽温);
  • 温度系数:≤±30ppm/℃,即容值随温度变化率≤0.3%;
  • 电压特性:容值不随直流偏置电压变化(与X7R介质±15%的温度漂移形成鲜明对比)。

该特性完全满足射频电路、精密滤波模块对容值稳定的需求。

3. 额定电压50V

直流额定电压50V,适用于大多数中低功率场景(如手机射频前端、路由器电源去耦);交流电压需降额至35V以下(70%额定值),避免介质击穿或老化。

4. 封装0402

  • 体积小巧:重量仅约0.005g,适配高密度PCB设计(如智能手机主板、小型IoT模块);
  • 工艺兼容:支持回流焊(峰值温度≤245℃)、波峰焊(温度≤260℃),焊接可靠性符合IPC-A-610标准;
  • 贴装效率:适配自动化SMT产线,贴装速度≥10000片/小时。

三、封装特性与典型应用场景

1. 封装优势

  • 小型化集成:0402封装可有效降低PCB布局面积,提升电路集成度(如5G手机射频模块需密集布置数十个此类电容);
  • 抗干扰性:封装材料屏蔽效果优异,减少高频信号串扰;
  • 耐环境性:可承受工业级温湿度变化,满足户外通信设备需求。

2. 典型应用场景

  • 消费电子:智能手机/平板的WiFi/蓝牙模块滤波、射频前端耦合电容(确保2.4G/5G信号传输稳定);
  • 通信设备:基站RRU(射频拉远单元)信号去耦、路由器谐振电路(提升信号抗干扰能力);
  • 工业控制:小型传感器节点电源滤波、MCU时钟电路耦合(满足低功耗、高稳定需求);
  • 医疗电子:便携式心电图仪信号调理模块(确保参数精度符合医疗标准)。

四、HRE芯声品牌技术优势

HRE作为国内MLCC领域的专业厂商,该产品依托以下核心技术:

  1. 介质材料优化:采用高纯度钛酸钡基C0G介质,损耗角正切(DF)≤0.15%(1kHz/1V条件下),高频下ESR低至0.5Ω,适合射频电路;
  2. 精密叠层工艺:电极层厚度均匀(≤1μm),容值一致性优于行业标准(±2%),避免批次差异;
  3. 可靠性测试:通过GB/T 2693-2001标准的高温存储(125℃/1000h)、温度循环(-55℃~125℃/1000次)、湿度测试(85℃/85%RH/1000h),失效率≤0.1 FIT(10^9小时);
  4. 供应链支持:月产能≥1000万片,可提供定制化服务(如±1%精度、汽车级AEC-Q200认证、真空包装)。

五、应用注意事项

  1. 焊接规范:回流焊需遵循IPC J-STD-020标准,峰值温度≤245℃,时间≤10秒;波峰焊温度≤260℃,时间≤5秒;
  2. 电压降额:实际工作电压(直流)不得超过50V,交流电压需降额至35V以下;
  3. 存储条件:常温(15℃~35℃)、干燥(湿度≤60%RH)环境存储,开封后24小时内使用,避免受潮;
  4. 静电防护:需在ESD防护环境下操作,避免静电损坏介质层。

该产品凭借稳定的容值特性、小型化封装及高可靠性,成为高频电子电路设计的优选组件,可满足不同领域对低损耗、高稳定电容的需求。

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
