TCC0805COG220J500BT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本信息与命名解析

TCC0805COG220J500BT是三环电子(CCTC) 推出的一款贴片多层陶瓷电容(MLCC),针对高频精密电路设计。其命名遵循行业通用规则,各段含义解析如下:

  • TCC:三环电子品牌标识;
  • 0805:英制封装尺寸(对应公制2.0mm×1.2mm×0.8mm典型厚度);
  • COG:EIA温度系数代码(对应IEC标准NPO),代表温度补偿型陶瓷;
  • 220:容值代码(22×10⁰ pF),即22pF;
  • J:容值精度等级(±5%);
  • 500:直流额定电压(50V);
  • BT:三环内部规格代码(包含封装细节、生产工艺等级等)。

该产品属于温度补偿型MLCC,核心优势在于容值稳定性、低损耗特性,适配高频/精密电路需求。

二、核心性能参数详解

2.1 容值与精度

容值标称22pF,精度±5%(J级),在-55℃~125℃宽温范围内,容值变化率≤±30ppm/℃,无明显老化现象(C0G材质固有特性),满足精密电路对容值一致性的要求。

2.2 电压特性

直流额定电压50V,峰值电压(浪涌电压)设计为75V(1.5倍额定电压),可承受短时间过压冲击;1kHz/1Vrms条件下交流电压额定值约35Vrms,适配小功率电源滤波场景。

2.3 温度与损耗特性

  • 温度系数:C0G(NPO),工作温度范围-55℃~125℃,容值随温度变化极小(≤±0.03%/℃);
  • 损耗角正切(tanδ):1kHz时≤0.15%,1MHz高频下仍保持低损耗(≤0.2%),适合射频、振荡器等高频电路。

2.4 封装与机械参数

封装尺寸0805(2.0×1.2×0.8mm),无引脚贴片结构,适配标准SMT产线;机械特性满足:振动(10~2000Hz,加速度10g)、冲击(1000g/0.5ms)、PCB弯曲(≤2mm),抗环境应力能力强。

三、材料与封装工艺特性

3.1 陶瓷材料

采用温度补偿型低介电常数陶瓷(主要成分为钛酸钡基复合材料),介电常数εr≈30~60,容值随电压、直流偏置变化可忽略(≤0.1%),区别于高介电常数的X7R/X5R材质(容值随偏置下降明显)。

3.2 电极与封装结构

  • 内部电极:镍基合金(低电阻、抗氧化);
  • 外部端电极:三层结构(镍底层→铜中间层→无铅锡银焊料顶层),符合RoHS 2.0环保标准,焊接兼容性好;
  • 封装工艺:多层陶瓷叠层+高温烧结,结构致密,无分层风险。

四、典型应用场景

该产品因低损耗、高稳定特性,广泛应用于以下领域:

4.1 高频射频电路

  • 射频振荡器、滤波器、耦合器(如蓝牙、WiFi模块);
  • 天线匹配网络、信号隔离电路。

4.2 精密模拟电路

  • 运算放大器反馈网络、比较器参考电路;
  • 高精度ADC/DAC滤波、基准电压去耦。

4.3 小功率电源与噪声抑制

  • 50V以下小功率电源的高频去耦、纹波抑制;
  • 传感器信号链的电磁干扰(EMI)滤波。

4.4 严苛环境应用

  • 汽车电子辅助电路(如传感器接口、车载通信);
  • 工业控制PLC、仪器仪表(符合宽温、抗振动要求)。

五、品牌与可靠性优势

5.1 三环电子(CCTC)品牌背书

三环电子是国内MLCC行业头部企业,拥有20余年生产经验,产能稳定(月产能超10亿只),通过ISO9001、IATF16949(汽车级)、RoHS 2.0等认证。

5.2 可靠性测试

产品经过全流程可靠性验证:

  • 高温存储(125℃/1000h):容值变化≤±1%;
  • 温度循环(-55℃~125℃/1000次):无性能衰减;
  • 焊接热冲击(回流焊峰值240℃):端电极无脱落。

5.3 环保与兼容性

无铅无卤设计,适配欧盟REACH、美国加州65等环保法规;端电极与Sn-Pb、无铅焊料均兼容,支持回流焊、波峰焊(需优化参数)。

六、选型与使用注意事项

6.1 参数匹配建议

  • 若需大容量(如μF级),需切换至X7R/X5R材质(C0G容值通常≤1000pF);
  • 汽车级应用需确认三环对应AEC-Q200认证版本(部分型号支持)。

6.2 焊接工艺要求

  • 回流焊温度曲线:预热区(150180℃/60120s)→升温区(180220℃/3060s)→峰值区(230~245℃/≤30s);
  • 避免手工焊(烙铁温度≤350℃,时间≤3s),防止陶瓷开裂。

6.3 存储与使用

  • 未开封产品存储于常温干燥环境(温度20~30℃,湿度≤60%),存储周期≤12个月;
  • 开封后需在24h内完成焊接,避免端电极受潮氧化。

该产品凭借稳定的性能、可靠的工艺及广泛的适配性,成为高频精密电路的优选MLCC方案。

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.
