TCC0402COG5R0C500AT 贴片陶瓷电容产品概述

一、产品核心定位与身份

TCC0402COG5R0C500AT是三环电子(CCTC)推出的高频高稳定型贴片陶瓷电容,属于其C0G(NPO)系列核心产品。该型号以0402英寸小型化封装为核心,精准匹配5pF容值、50V额定电压需求,兼具±0.25pF高容差精度与0.5mm超薄厚度,专为对容值稳定性、高频损耗要求严苛的电子系统设计。

二、关键电气性能参数

作为C0G材质电容,其电气性能聚焦“稳定、精准、低耗”三大核心:

  1. 容值与精度:标称容值5pF,容差范围±0.25pF(即容值波动控制在4.75pF~5.25pF之间),远优于常规X7R电容的±5%精度,满足精密电路对容值一致性的要求;
  2. 电压与温度系数:额定直流电压50V,温度系数为C0G级(国际标准对应NPO),即-55℃~125℃宽温范围内,容值变化率≤±0.06%(换算为ppm级约±30ppm/℃),是目前陶瓷电容中温度稳定性最优的材质之一;
  3. 损耗与谐振特性:1kHz频率下损耗角正切(tanδ)典型值≤0.1%,高频(如100MHz)下仍保持低损耗;0402封装的小体积特性使其自谐振频率(SRF)可达数百MHz,适合射频电路的谐振、滤波应用。

三、物理封装与机械特性

  1. 封装尺寸:采用0402英寸贴片封装(公制1005规格),具体尺寸为长1.0mm±0.1mm、宽0.5mm±0.1mm,适配高密度SMT贴装需求;
  2. 厚度规格:芯片本体厚度为0.5mm±0.05mm,比常规0402电容(通常0.6mm以上)更薄,可有效降低模组整体高度;
  3. 端电极结构:采用三层复合电极设计(银内电极+镍阻挡层+无铅焊端),兼容RoHS 2.0标准,焊接兼容性优异,可通过回流焊(260℃峰值温度)、波峰焊等常规工艺贴装,焊接后剪切强度≥10N(符合IPC标准)。

四、C0G(NPO)材质的核心优势

相比X7R、Y5V等常规陶瓷电容,C0G材质具有不可替代的优势:

  • 宽温稳定性:在-55℃~125℃极端温度范围内,容值无明显漂移,避免因温度变化导致电路性能波动;
  • 无老化效应:长期工作(如1000小时以上)容值变化≤±0.2%,适合需要长期可靠运行的工业、医疗设备;
  • 低非线性失真:在射频信号下无电压依赖性失真,保证通信信号的完整性;
  • 抗干扰能力强:低损耗特性减少信号能量损耗,同时抑制电磁干扰(EMI)。

五、典型应用场景

该型号电容因“小体积、高稳定、低损耗”特性,广泛应用于以下领域:

  1. 射频通信模块:WiFi 6、蓝牙5.0等无线模块的滤波、匹配网络;
  2. 精密模拟电路:运放的反馈电容、高精度ADC/DAC的滤波电容;
  3. 高频振荡电路:晶振的负载电容(保证振荡频率稳定);
  4. 汽车电子:车载导航、ADAS系统的传感器信号滤波(宽温适配汽车环境);
  5. 医疗设备:监护仪、超声设备的信号调理电路(对容值稳定性要求高)。

六、可靠性与环境适应性

TCC0402COG5R0C500AT通过多项可靠性测试,满足严苛应用环境:

  • 耐焊接热:260℃回流焊3次后,容值变化≤±0.3%,无开裂、脱落;
  • 湿热测试:85℃/85%RH环境下1000小时,容值变化≤±0.5%,绝缘电阻≥10^9Ω;
  • 机械可靠性:抗弯折测试(弯曲半径2mm)后性能无衰减,抗振动测试(10~2000Hz,加速度2g)符合MIL-STD-202标准;
  • 环境适应性:符合欧盟RoHS、REACH标准,无铅环保,可用于出口产品。

七、品牌与品质保障

三环电子(CCTC)是国内陶瓷电容领域的龙头企业,拥有20余年专业生产经验,产品通过ISO 9001、IATF 16949(汽车级)等认证。TCC0402COG5R0C500AT采用全自动化生产流程,每批次产品均经过容值、损耗、温度特性等全检,一致性达±0.1pF以内,可满足批量生产的稳定性要求。

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
