TCC0805COG200J500BT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本属性与型号解析

TCC0805COG200J500BT是三环电子(CCTC) 推出的一款工业级贴片多层陶瓷电容(MLCC),核心定位为高频高精度电路中的稳定信号滤波与容性补偿。其型号各段含义清晰对应产品关键特征:

  • TCC:三环电子品牌前缀;
  • 0805:英制封装尺寸(对应公制2.0mm×1.2mm),适配常规PCB贴装工艺;
  • COG:温度系数标识(符合EIA标准,对应IEC的NP0类),代表极低温度漂移;
  • 200:容值编码(20×10⁰=20pF);
  • J:精度等级(±5%);
  • 500:额定直流电压(50V);
  • BT:封装细节与批次标识(三环内部工艺编码,含端电极优化信息)。

二、关键性能参数详解

该产品核心参数聚焦稳定性、高频特性与可靠性,具体如下:

1. 容值与精度

  • 标称容值:20pF;
  • 精度范围:±5%(J档),满足工业级电路对容值一致性的要求;
  • 容值老化:COG类陶瓷无明显老化效应(长期使用容值变化<0.1%)。

2. 电压与温度特性

  • 额定直流电压:50V(最大工作电压需降额至40V以下,避免绝缘击穿);
  • 温度系数:±30ppm/℃(-55℃~+125℃宽温范围),是所有陶瓷电容中温度稳定性最优的类别;
  • 工作温度范围:-55℃~+125℃,适配车载、工业控制等极端环境。

3. 高频与损耗特性

  • 损耗角正切(tanδ):典型值<0.15%(1kHz下),低损耗适合射频信号传输;
  • 自谐振频率(SRF):约1.5GHz(20pF典型值),在1GHz以下频段表现为纯电容特性;
  • 绝缘电阻:>10¹⁰Ω(25℃、50V DC下),高绝缘性减少漏电流干扰。

三、封装与结构特点

采用0805贴片封装,结构设计适配自动化生产与高密度PCB布局:

1. 封装尺寸(公制)

  • 长度:2.0±0.2mm;
  • 宽度:1.2±0.2mm;
  • 厚度:0.8±0.1mm(含端电极);
  • 端电极:Ni/NiSn双层结构,焊接兼容性好(适配Sn-Pb与无铅回流焊)。

2. 多层陶瓷结构

通过叠层介质+内电极工艺实现小体积大容量:

  • 介质层:高纯度钛酸钡基陶瓷(COG类),保证温度稳定性;
  • 内电极:银钯合金(Ag-Pd),耐温性优于纯银电极,适配回流焊高温(峰值260℃)。

四、适用场景与应用优势

该产品因低损耗、高稳定、小体积,广泛应用于以下场景:

1. 高频通信电路

  • 射频(RF)模块:蓝牙、WiFi、5G基站的信号滤波;
  • 振荡器:晶体振荡器(XO)的负载电容补偿,保证频率稳定。

2. 工业控制与车载电路

  • PLC(可编程逻辑控制器):模拟量输入滤波,减少电磁干扰;
  • 车载传感器:温度传感器、压力传感器的信号调理,适配-40℃~+85℃车载环境。

3. 电源滤波电路

  • 低压直流电源:输出端滤波,抑制纹波(≤10mV);
  • EMI滤波:电源线共模/差模滤波,符合电磁兼容标准(EN55032)。

核心应用优势

  • 宽温稳定:COG类无温度漂移,避免环境温度变化导致电路性能波动;
  • 高频低损:适合1GHz以下射频信号,信号失真率<0.05%;
  • 高可靠性:三环工艺成熟,通过1000小时高温存储测试(125℃),失效率<0.1%。

五、品牌与可靠性保障

三环电子(CCTC)是国内MLCC领域头部厂商,该产品具备完善的可靠性认证:

1. 标准合规

  • 国际标准:符合IEC 61039、JIS C 5102;
  • 环保认证:RoHS 2.0 compliant(无铅、无镉、无汞),REACH SVHC合规。

2. 可靠性测试

  • 温度循环:-55℃~+125℃,1000次循环,容值变化<0.2%;
  • 湿度加载:85℃/85%RH,500小时,绝缘电阻>10⁹Ω;
  • 焊接可靠性:回流焊后剪切强度≥2N(符合IPC-7351标准)。

六、选型与使用注意事项

为保证产品性能与寿命,需注意以下细节:

1. 电压匹配

  • 直流电路:工作电压≤40V(降额20%);
  • 交流电路:峰值电压≤35V(降额30%),避免容值漂移或击穿。

2. 焊接工艺

  • 回流焊:温度曲线需符合IPC/JEDEC J-STD-020(峰值260℃,时间≤10秒);
  • 手工焊接:禁止超过350℃,焊接时间≤3秒(避免介质层开裂)。

3. 存储与静电防护

  • 存储:常温干燥环境(1535℃,4060%RH),开封后12个月内使用;
  • 静电:操作需接地(人体静电≤100V),避免静电损伤介质层。

该产品凭借三环成熟工艺与COG类核心优势,是高频高精度电路的高性价比选择,适用于通信、工业、车载等多领域。

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.
