CGA0402C0G7R0C500GT — 产品概述

一、产品简介

CGA0402C0G7R0C500GT(HRE 芯声)为0402封装的高稳定陶瓷电容,标称容量7 pF,容差±0.25 pF,额定电压50 V,温度系数为C0G(有时称为NP0)。该产品以C0G介质的极低温漂和低损耗特性为核心,面向精密模拟、射频和高频应用场景,适用于对容值稳定性、频率响应和可重复性有较高要求的电路设计。

二、主要特点

  • 极高温度稳定性:C0G介质在−55°C至+125°C范围内几乎无容量漂移,适合对温度敏感的电路。
  • 高精度容差:±0.25 pF 的公差使其在滤波、谐振和定时电路中能提供更精确的电容量控制。
  • 小尺寸封装:0402(约1.0×0.5 mm)有利于高密度贴装与空间受限的板级设计。
  • 低损耗、低介电吸收:适合高Q值网络、振荡器与射频前端。
  • 中等额定电压:50 V 满足多数信号链和小功率电源的应用需求。

三、典型应用

  • 射频匹配网络、带通/陷波滤波器、天线调谐。
  • 精密振荡器、时钟回路与高稳定时序元件。
  • 模拟前端中的耦合/去耦与阻抗定点。
  • 测量仪表、传感器接口与低漂移增益网络。
  • 高密度移动终端与消费电子的信号链路。

四、关键技术参数(摘要)

  • 容值:7 pF
  • 容差:±0.25 pF
  • 额定电压:50 V DC
  • 温度系数/介质:C0G(NP0)——极低的温度依赖性和良好的频率稳定性
  • 封装:0402(国际标准外形尺寸)

五、封装与可靠性建议

0402尺寸提供了良好的装配密度,但对贴装、焊接与机械应力较敏感。建议:

  • 按照厂商推荐焊盘与回流工艺(参考IPC/JEDEC标准)进行焊接,回流峰值温度通常不超过260°C。
  • 贴装后避免在元件上直接施加机械力或使用硬刮擦工具,防止裂纹产生。
  • 对于振动或热循环苛刻的应用,可考虑在关键元件下使用粘接或加固工艺。
  • 在高频设计中应注意布局寄生电感/寄生电容对性能的影响,尽量缩短引线长度和优化地平面。

六、选型建议与注意事项

  • 若设计对温度稳定性和低损耗有严格要求,C0G是首选;若需要更大容量,应选择更大封装的同类型产品。
  • 7 pF 且 ±0.25 pF 的精度在小信号和射频电路中非常有价值,但测量和在线测试时需使用高精度 LCR 仪并做好测试夹具校准。
  • 虽然C0G对直流偏置敏感性低,但在高电压或脉冲环境下仍需评估击穿与脉冲承受能力,并考虑必要的浪涌保护。
  • 关注生产批次和规格表,一些参数(如介电常数、公差的实际实现)可能因制造工艺和尺寸而有微小差异。

七、结语

CGA0402C0G7R0C500GT(HRE 芯声)以其小尺寸、高稳定性与高精度特性,适合用于精密射频/模拟电路与高密度PCB设计。在实际应用中,配合合理的布局、焊接工艺与测试方法,可以最大化其在频率稳定性与长期可靠性方面的优势。若需更详细的焊接曲线、可靠性数据或推荐封装尺寸图,请参考厂商详细资料或联系技术支持。

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
