HRE(芯声)CGA0402C0G390J500GT 多层陶瓷电容产品概述

一、产品基本属性

HRE(芯声)CGA0402C0G390J500GT是一款Class 1型多层陶瓷电容(MLCC),专为小型化、高稳定性电子电路设计。其型号各部分含义清晰:

  • CGA:芯声MLCC系列代号;
  • 0402:英制封装尺寸(0.04in×0.02in,公制1.0mm×0.5mm);
  • C0G:温度系数(对应IEC标准NP0类);
  • 390:容值编码(39×10⁰=39pF);
  • J:精度等级(±5%);
  • 500:直流额定电压(50V);
  • GT:包装/批次辅助标识。

二、核心性能参数解析

1. 容值与精度

容值39pF,精度±5%(J档),满足通用电路的滤波、耦合、匹配需求——既避免过高精度带来的成本冗余,又能覆盖大多数中低端射频、通信电路的容值偏差要求。

2. 温度稳定性(C0G特性)

C0G属于Class 1陶瓷电容,温度系数≤±30ppm/℃,容值随温度(-55℃~+125℃)变化极小(典型值<0.1%)。该特性使其成为射频(RF)、振荡器、高精度滤波器的首选,避免温度波动导致的电路性能漂移。

3. 额定电压与降额

直流额定电压50V,实际应用需遵循80%降额原则(即最大工作电压≤40V DC);交流电压需进一步降额(AC峰值≤20V,约为DC额定电压的40%),防止介质击穿或漏电流增大。

4. 高频特性

MLCC的多层结构赋予其低等效串联电阻(ESR)和低等效串联电感(ESL),C0G类更是在1GHz以上频段仍保持稳定容值,适合WiFi、蓝牙、5G sub-6GHz等高频应用。

三、封装与结构特点

1. 0402封装优势

体积小巧(1.0mm×0.5mm×0.5mm典型高度),适配便携式设备(手机、智能手表)、小型化模块(路由器、传感器) 的高密度贴装,支持0201/0402混贴的自动化生产。

2. 结构可靠性

  • 介质层:采用高纯度钛酸钡基陶瓷,介电常数稳定;
  • 内电极:镍(Ni)基合金,降低成本同时保证导电性;
  • 外电极:镍镀层+无铅锡银铜(SnAgCu)或锡铅(SnPb)镀层,符合RoHS 2.0标准,焊接兼容性强(回流焊峰值温度230~245℃)。

四、典型应用场景

  1. 射频通信:手机、WiFi 6模块、蓝牙5.3设备中的滤波、耦合、阻抗匹配网络;
  2. 消费电子:智能手表、平板电脑的电源去耦、信号耦合电路;
  3. 工业控制:低电压PLC、传感器模块的滤波电路(耐温-40℃~+85℃环境);
  4. 汽车电子:低压辅助电路(如车身控制模块BCM)的去耦电容(需确认符合AEC-Q200标准,芯声部分型号已认证)。

五、可靠性与环境适应性

  • 温度范围:工作温度-55℃+125℃,存储温度-40℃+85℃;
  • 机械性能:抗振动(10~2000Hz,加速度10g)、抗冲击(峰值加速度500g)符合IEC 60068标准;
  • 寿命:额定参数下工作寿命≥10⁶小时,漏电流≤1μA(25℃,50V DC)。

六、选型与使用注意事项

  1. 电压匹配:避免超压使用,交流电路需额外降额;
  2. 焊接工艺:回流焊需控制升温速率(≤3℃/s),防止陶瓷开裂;
  3. 包装:默认卷带包装(10000个/卷),适合SMT自动化生产;
  4. 替代选型:若需更高精度(±1%),可选择同系列J档换F档(如CGA0402C0G390F500GT);若需更高电压(100V),需换用0603封装型号。

该产品平衡了小型化、稳定性与成本,是通用电子电路中39pF容值的高性价比选择,尤其适合对温度稳定性要求较高的射频与通信场景。

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
