TCC0402COG1R0C500AT 贴片多层陶瓷电容(MLCC)产品概述

TCC0402COG1R0C500AT是三环电子(CCTC)推出的一款小容量高频贴片MLCC,凭借稳定的C0G介质特性、50V额定电压及0402紧凑型封装,广泛适配高频通信、数字电路等对容值稳定性要求较高的场景,是电子设计中信号链路的可靠基础元器件。

一、产品基本属性梳理

该型号通过各段代码清晰传递核心参数,具体解析及基础属性如下:

参数项 具体参数 产品型号 TCC0402COG1R0C500AT 封装尺寸(英制/公制) 0402 / 1005 标称容值 1pF 容值精度 ±0.5%(典型值) 额定直流电压 50V DC 温度系数 COG(对应国际标准NP0) 介质类型 温度补偿型陶瓷 品牌 三环电子(CCTC) 封装形式 表面贴装(SMD) 工作温度范围 -55℃ ~ +125℃

型号代码解析:

  • TCC:三环电子品牌标识;
  • 0402:英制封装尺寸(0.04×0.02英寸,公制1005);
  • COG:温度系数代号(容值随温度变化极小);
  • 1R0:容值标识(1R0=1pF);
  • C500:额定电压50V;
  • AT:卷带包装(适配SMT批量贴装)。

二、核心性能特点解析

该产品的核心优势集中于温度稳定性、高频损耗控制及封装紧凑性,具体如下:

1. 超稳定温度特性

C0G介质属于温度补偿型陶瓷,容值随温度变化率仅**±30ppm/℃**(-55℃~125℃全温区),远优于X7R(±15%)、Y5V(±20%)等介质,可避免因温度波动导致的容值漂移,适配工业宽温、户外通信等场景。

2. 低损耗高频性能

介质损耗角正切值(DF)典型值≤0.15%(1kHz下),在GHz级高频电路中能量损耗极小,能有效保证射频信号的完整性,适合蓝牙、WiFi等无线通信链路的滤波/耦合。

3. 紧凑封装与高可靠性

0402封装体积仅1.0×0.5mm,适配高密度PCB设计;MLCC无极性、无引线电感(相比电解电容),抗干扰能力强,长期使用失效率≤1Fit(1Fit=10^-9次失效/小时),满足量产可靠性要求。

4. 中低压场景适配

50V额定电压覆盖多数消费电子、工业控制的中低压需求,实际工作电压可在40V以内安全运行(降额80%设计),兼顾电压裕量与使用寿命。

三、典型应用场景

该产品凭借上述特性,广泛应用于以下场景:

1. 高频通信模块

  • 蓝牙5.0/WiFi 6模块的射频前端滤波电容,利用低损耗特性减少信号衰减;
  • 5G小基站的收发链路耦合电容,稳定容值保证阻抗匹配精度。

2. 数字时钟电路

  • MCU、FPGA的外部晶振谐振电容(如12MHz、24MHz晶振),避免时钟漂移提升时序精度;
  • 实时时钟(RTC)电路的补偿电容,保证时间同步稳定性。

3. 消费电子终端

  • 智能手机主板的信号链路去耦电容,0402封装适配手机高密度PCB;
  • 平板电脑、智能手表的传感器接口滤波电容,抑制电磁干扰。

4. 工业控制单元

  • 小型温度/压力传感器的接口电路电容,宽温范围满足工业环境波动;
  • 低功耗PLC的数字输入输出(DI/DO)滤波电容,提升信号抗噪性。

四、品牌与质量保障

三环电子(CCTC)是国内MLCC领域头部厂商,拥有20余年研发生产经验,该产品具备以下质量优势:

  • 认证齐全:通过ISO 9001、IATF 16949质量体系,符合RoHS 2.0、REACH环保标准;
  • 生产工艺:自动化卷带封装,贴装良率≥99.5%,批量供货稳定;
  • 测试严格:每批次经过温度循环、耐电压、ESD等测试,确保性能一致性。

五、选型与使用注意事项

  1. 容值精度匹配:若设计对容值精度要求≤±0.5%,该产品完全适配;常规场景可满足±1%需求;
  2. 电压降额:实际工作电压建议不超过40V(额定电压80%),避免过压老化;
  3. 贴装工艺:0402封装需高精度贴片机(贴装精度≤±0.05mm),回流焊温度控制在230℃~260℃;
  4. 环境防护:强电磁干扰场景建议搭配屏蔽罩,避免信号串扰。

综上,TCC0402COG1R0C500AT以稳定的C0G特性、紧凑封装及可靠质量,成为高频电路、数字系统中高性价比的选型方案,适配从消费电子到工业控制的多类场景需求。

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
