TCC0402COG220F500AT 贴片多层陶瓷电容(MLCC)产品概述

TCC0402COG220F500AT是三环电子(CCTC)推出的一款高精度、高稳定性贴片多层陶瓷电容(MLCC),采用0402(1005)小型化封装,专为对容值精度、温度稳定性要求严苛的高频/精密电路设计,广泛适配消费电子、汽车电子、工业控制等领域的量产需求。

一、产品定位与基本属性

该产品属于C0G(NP0)类MLCC,是MLCC中温度系数最稳定、精度最高的品类之一,核心定位为“高频精密电路的基准电容元件”。不同于X7R/X5R等铁电介质电容(容值随温度、电压变化明显),C0G类采用顺电体陶瓷介质,容值特性不受环境温度、工作电压(额定范围内)影响,适合对信号稳定性要求极高的场景。

产品基本属性清晰:由三环电子(CCTC)原厂生产,符合RoHS 2.0、REACH等环保标准,无铅焊接兼容,可直接用于各类高密度PCB设计。

二、核心电气性能参数

TCC0402COG220F500AT的关键参数经过严格校准,满足工业级及消费电子的高精度要求,具体如下:

参数项 规格值 说明 标称容值 22pF 代码“220”表示22×10⁰ pF 容值精度 ±1% 精度代码“F”对应国际通用±1%标准 额定直流电压(VR) 50V 代码“500”表示50V(无额外后缀为直流) 温度系数 C0G(NP0) 温度范围-55℃~+125℃,容值变化≤±30ppm/℃ 损耗角正切(tanδ) ≤0.15%(1kHz,25℃) 低损耗特性,减少高频信号能量损耗 工作温度范围 -55℃~+125℃ 宽温适应性,覆盖汽车、工业场景需求

注:参数均为典型值,具体以原厂 datasheet 为准。

三、封装设计与可靠性

3.1 小型化封装优势

采用0402(英制)/1005(公制) 贴片封装,尺寸仅为1.0mm×0.5mm×0.5mm(长×宽×高),大幅节省PCB空间,适配智能手机、智能穿戴、小型化通信模块等高密度设计需求。封装引脚采用镍钯金(NiPdAu)镀层,焊接兼容性强,支持回流焊、波峰焊等常规工艺,焊点可靠性达汽车级标准(符合IATF16949要求)。

3.2 长期稳定性与可靠性

  • 无老化效应:C0G顺电体介质无铁电畴翻转,容值随时间变化率≤0.1%/1000小时,远优于X7R类电容(通常≥1%);
  • 抗环境干扰:耐振动(10~2000Hz,加速度10g)、耐冲击(1500g,0.5ms),适合汽车颠簸、工业设备振动场景;
  • 焊接可靠性:回流焊温度曲线兼容(峰值260℃±5℃,持续10~20秒),无“立碑”“虚焊”等常见贴片缺陷。

四、典型应用领域

TCC0402COG220F500AT的高精度、宽温稳定特性,使其成为以下场景的核心元件:

4.1 高频通信电路

  • 蓝牙5.0/5.1模块、WiFi 6/6E射频前端:用于滤波、匹配网络,避免温度变化导致的频率偏移,保证信号传输稳定性;
  • 2.4GHz/5GHz无线局域网(WLAN):容值稳定确保信道带宽精准,减少信号串扰。

4.2 汽车电子系统

  • 胎压监测(TPMS)、倒车雷达:宽温(-40℃~+85℃)下容值无漂移,保证传感器信号采集准确;
  • 车载信息娱乐系统:高精度电容用于音频滤波,提升音质清晰度。

4.3 工业控制与精密仪器

  • PLC模拟量输入模块:容值精度±1%确保信号滤波、耦合无偏差,提升数据采集精度;
  • 高频振荡电路(如晶振匹配):C0G的温度稳定性避免晶振频率偏移,保证时钟信号准确。

4.4 消费电子终端

  • 智能手机射频天线匹配:小型化封装适配机身紧凑设计,稳定容值提升信号接收灵敏度;
  • 智能手表传感器电路:低损耗特性减少功耗,延长电池续航。

五、品牌与品质保障

三环电子(CCTC)是国内MLCC领域的龙头企业之一,产品通过以下认证与保障:

  • 体系认证:ISO9001质量管理体系、IATF16949汽车电子体系;
  • 环保认证:RoHS 2.0、REACH、无卤素(HF);
  • 品质管控:每批次产品经过容值、温度系数、焊接可靠性全检,批次一致性达±0.5%(优于标称±1%);
  • 供应链优势:国内产能稳定,交期短,可支持JIT(准时化生产)需求。

综上,TCC0402COG220F500AT凭借高精度、宽温稳定、小型化等核心优势,成为高频精密电路的理想选择,适配多领域量产需求,是本土客户替代进口高端MLCC的优质方案。

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.
