CGA0402C0G391J500GT多层陶瓷电容(MLCC)产品概述

一、产品基本信息

CGA0402C0G391J500GT是HRE芯声推出的0402封装C0G系列多层陶瓷电容,属于温度稳定型(NP0类)MLCC,专为高频、高精度、宽温稳定场景设计。型号各部分含义清晰:

  • CGA:HRE芯声C系列MLCC封装标识;
  • 0402:英制封装尺寸(0.04英寸×0.02英寸),对应公制1005(1.0mm×0.5mm);
  • C0G:温度系数代码(NP0类),容值稳定性极佳;
  • 391:容值编码(39×10¹=390pF);
  • J:精度代码(EIA标准±5%);
  • 500:额定直流电压50V;
  • GT:编带包装标识(10000片/盘)。

二、核心性能参数

该产品关键参数聚焦高稳定、低损耗、小型化,具体如下:

参数项 数值/规格 说明 标称容值 390pF(391编码) 无直流偏置效应(C0G特性) 精度 ±5%(J级) 满足高精度电路需求 额定直流电压 50V 适合中低压电路应用 温度系数 C0G(NP0) -55℃~125℃内容值变化≤±30ppm/℃ 工作温度范围 -55℃~125℃ 覆盖工业/商业宽温场景 损耗角正切(tanδ) ≤0.15%(1kHz,25℃) 低损耗适合高频信号传输 封装尺寸 1.0mm×0.5mm×0.5mm(典型) 0402封装适配高密度PCB布局 包装方式 编带(GT) 10000片/盘,适合自动化贴装

三、材料与工艺特点

  1. C0G稳定介质:采用钛酸钡基陶瓷材料,无铁电效应,容值不受温度、直流偏置电压影响(区别于X7R/Y5V的温漂/偏置降容);
  2. 多层叠层工艺:通过精密印刷、叠层、高温烧结制成,电极采用银钯合金(Ag-Pd),避免氧化,焊接可靠性强;
  3. 小型化设计:0402封装实现“小体积大容值”,满足消费电子、通信设备的迷你化趋势;
  4. 环保合规:符合RoHS 2.0、REACH标准,无铅无卤,适配全球市场要求。

四、典型应用场景

因C0G的高稳定、低损耗特性,该产品广泛用于对容值精度要求严格的场景:

  1. 射频通信:手机、基站、WiFi模块的射频前端滤波、耦合电容,保证信号传输无失真;
  2. 高精度模拟电路:运算放大器、ADC/DAC的反馈网络、滤波电容,避免温漂导致的电路精度下降;
  3. 高频振荡电路:晶振匹配电容、谐振回路电容,确保振荡频率准确(如时钟电路、射频振荡器);
  4. 工业控制:传感器接口、数据采集电路的滤波电容,适应-55℃~125℃的工业环境;
  5. 汽车电子辅助:车载娱乐、传感器模块的辅助电容(需确认汽车级认证,参数支持宽温)。

五、选型与应用注意事项

  1. 电压降额:建议工作直流电压≤37.5V(额定电压75%),避免长期高压老化,提升寿命;
  2. 温度适配:仅适用于-55℃125℃场景,若温度超出需更换其他介质(如X7R适合-55℃125℃但容值稳定差);
  3. 焊接工艺:采用无铅回流焊,峰值温度控制在240℃~250℃(10秒内),避免过温导致陶瓷开裂;
  4. 偏置效应:C0G无直流偏置降容,无需担心电压变化导致容值波动(X7R在偏置下容值可降30%以上);
  5. 储存要求:未开封产品储存在25℃±5℃、湿度≤60%环境,开封后1个月内使用,避免引脚氧化。

六、品牌与可靠性说明

HRE芯声是国内专注MLCC研发生产的企业,该产品通过多项可靠性测试:

  • 高温寿命:125℃、50V下1000小时,容值变化≤±1%,损耗变化≤±10%;
  • 温度循环:-55℃~125℃循环500次,无开裂、容值变化≤±1%;
  • 湿度寿命:85℃/85%RH、50V下1000小时,容值变化≤±1%;
    产品满足商业级与工业级要求,适用于对稳定性要求高的设备。

综上,CGA0402C0G391J500GT以高稳定、低损耗、小型化为核心优势,是射频、模拟、工业等领域的高性价比选型。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
