CGA0402C0G9R0B500GT 多层陶瓷电容(MLCC)产品概述

这款HRE芯声推出的CGA0402C0G9R0B500GT,是针对中低压、高频及精密电路设计的高性能MLCC,凭借C0G温度系数的稳定特性、小型化封装及50V额定电压优势,成为消费电子、射频通信等领域的常用选型。

一、产品基本信息

型号CGA0402C0G9R0B500GT的核心参数清晰明确:

  • 容值:标称9.0pF,C0G介质典型精度±5%;
  • 额定电压:50V DC(适配中低压电路,比常规0402封装的10V/16V覆盖场景更广);
  • 温度系数:C0G(行业称NP0,陶瓷介质中温度特性最稳定的类型);
  • 工作温度:-55℃~+125℃(覆盖汽车、工业等宽温环境);
  • 封装:0402英制(公制1005,尺寸为长1.0±0.2mm、宽0.5±0.2mm、厚0.5±0.1mm);
  • 品牌与包装:HRE(芯声),常规为卷带包装(适配自动化贴装)。

二、核心性能优势

  1. 温度稳定性优异
    C0G介质的容值随温度变化极小——在-55℃至+125℃全温范围内,容值偏差不超过±0.3%(对应30ppm/℃的温度系数),远优于X7R(±15%)、Y5V(±20%)等常规介质,能避免温漂对精密电路的影响。

  2. 高频损耗极低
    C0G的介电常数(εr)约30~50,远低于高容值介质(如Y5V的εr可达10000+),因此1kHz下的损耗角正切(tanδ)仅<0.001,可有效减少射频信号的能量衰减,适配WiFi、蓝牙等2.4GHz/5GHz频段的电路。

  3. 电压适配性强
    50V DC的额定电压无需升级到更大封装(如0603),既能覆盖普通消费电子的需求,也能满足汽车传感器、工业控制等中低压场景,避免过压击穿风险。

  4. 容值精度可靠
    容值受电压、频率的影响极微——即使在额定电压下,容值变化也小于0.1%,适合作为运放反馈电容、射频耦合电容等对精度敏感的元件。

三、封装与工艺特点

  1. 小型化高密度布局
    0402封装体积仅0.5mm³左右,能在高密度PCB上实现紧凑设计,适配智能手表、无线耳机等小型化电子设备的空间限制。

  2. 端电极工艺优化
    采用三层端电极结构:内层为银钯合金(与陶瓷介质兼容性好,减少界面失效)、中间为镍层(防氧化)、外层为无铅锡银铜(符合RoHS标准,焊接兼容性强),可适配回流焊、波峰焊等常规工艺。

  3. 高精度叠层技术
    HRE芯声通过控制每层陶瓷介质的厚度一致性,确保容值偏差稳定在±5%以内,同时提升电容的机械强度,减少振动、冲击下的开路/短路风险。

四、典型应用场景

  1. 射频通信电路
    用于WiFi、蓝牙、LTE模块的滤波、耦合、去耦电容——低损耗特性减少信号衰减,温度稳定确保不同环境下的通信质量。

  2. 精密模拟电路
    运放的反馈电容、传感器信号调理电容(如压力、温度传感器)——容值稳定不影响信号精度,避免温漂导致的失真。

  3. 汽车电子辅助电路
    汽车车身控制模块、传感器信号调理电路的电容——宽温范围(-55~125℃)满足汽车舱内/外的环境需求,50V电压适配部分高压辅助电路。

  4. 工业控制模块
    PLC、变频器的信号滤波电容——宽温、高可靠特性适配工业现场的高低温、湿度变化等复杂环境。

五、可靠性与使用注意事项

  1. 可靠性验证
    经HRE芯声测试,该电容在-55℃至+125℃下持续工作1000小时,容值变化小于±0.2%;振动(10~2000Hz,2g加速度)、冲击(1000m/s²,1ms持续)测试后无失效,符合IPC J-STD-001标准。

  2. 使用注意事项

  • 电压降额:建议实际工作电压不超过额定电压的80%(即40V),避免长期过压导致介质老化;
  • 焊接工艺:回流焊峰值温度控制在240~250℃,时间不超过10秒;波峰焊温度不超过260℃,防止热应力开裂;
  • 静电防护:MLCC对静电敏感(ESD阈值200V~1kV),操作需佩戴防静电手环,使用防静电工作台;
  • 存储条件:未开封产品存储在25±5℃、40~60%RH的干燥环境中,开封后建议1个月内使用完毕。

总结:CGA0402C0G9R0B500GT凭借C0G介质的稳定特性、50V额定电压及小型化封装,成为高频、精密电路的高性价比选型,适用于消费电子、射频通信、汽车电子等多领域,只需注意电压降额及静电防护即可保障长期可靠性。

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.
