TCC1206COG102J631DT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本定位与属性

TCC1206COG102J631DT是CCTC(三环)电子推出的高压贴片多层陶瓷电容(MLCC),属于1206封装系列中的中高压稳定型产品。该电容针对高压小容值、容值稳定性要求严苛的应用场景设计,采用C0G(NP0)温度系数陶瓷介质,兼具高耐压、低损耗、宽温稳定等核心特性,是工业控制、高压电源、射频电路等领域的优选元件。

二、核心技术参数详解

  1. 容值与精度:标称容值1nF(标识代码“102”,即10×10²pF),精度等级为±5%(EIA代码“J”),满足大多数精密电路的容值偏差要求;
  2. 额定电压:直流额定电压630V,可适配高压环境下的持续工作(需注意电压降额,见第六部分);
  3. 温度特性:C0G介质(EIA对应NP0类),温度系数≤±30ppm/℃,工作温度范围为-55℃~+125℃,容值随温度变化的波动可忽略;
  4. 封装尺寸:英制1206封装(公制3216),具体尺寸为:长2.0±0.2mm、宽1.2±0.2mm、厚度0.5±0.1mm,兼容标准贴片焊接工艺;
  5. 损耗与绝缘:1kHz/25℃条件下,损耗角正切(tanδ)≤0.15%,绝缘电阻≥10⁴MΩ(25℃,50V DC),信号损耗极低且绝缘性能优异。

三、C0G介质的温度稳定性优势

C0G是MLCC中温度稳定性最优的介质材料,与X7R(±15%容值变化)、Y5V(±82%容值变化)等材料相比,其容值随温度、电压、时间的变化可忽略不计:

  • 温度变化:从-55℃到+125℃,容值偏差不超过±0.3%(按±30ppm/℃计算);
  • 电压影响:630V额定电压下,容值变化≤0.1%(远低于高压电容常见的容值漂移);
  • 时间老化:1000h高温存储后,容值变化≤0.5%,长期可靠性突出。
    该特性使其特别适合对容值一致性、稳定性要求高的高频振荡、精密滤波场景。

四、典型应用场景适配

结合核心参数,TCC1206COG102J631DT主要适配以下场景:

  1. 高压电源滤波:开关电源、LED驱动电源的高压侧(AC-DC转换后)滤波,抑制EMI干扰,稳定输出电压;
  2. 高频振荡电路:晶体振荡器、压控振荡器(VCO)的负载电容,确保振荡频率稳定(容值变化直接影响频率精度);
  3. 射频信号耦合:射频收发器、天线匹配电路中的耦合电容,低损耗特性避免信号衰减,稳定相位;
  4. 工业控制高压电路:PLC、伺服驱动器的高压驱动电路旁路电容,耐温耐湿适合工业环境;
  5. 测试测量设备:耐压测试仪、示波器探头的高压电容元件,满足高精度测试需求。

五、可靠性与品质保障

CCTC作为国内MLCC龙头厂商,该产品通过多项可靠性测试,符合国际国内标准:

  • 标准认证:符合GB/T 2693《电子元器件用陶瓷介质电容器》、IEC 60384-1《电子设备用固定电容器 第1部分:总规范》,且通过RoHS 2.0、无卤素认证;
  • 可靠性测试:
    • 高温存储:125℃/1000h,容值变化≤0.5%,绝缘电阻无明显下降;
    • 温度循环:-55℃~+125℃(500次循环),无开裂、参数漂移;
    • 耐电压测试:630V DC/1min,无击穿、漏电流超标;
  • 焊接可靠性:兼容无铅回流焊(峰值温度245±5℃,时间≤60s),焊接后引脚附着力≥5N。

六、选型与使用注意事项

  1. 电压降额:高压应用建议采用80%降额设计(即实际工作电压≤504V DC),避免过压导致介质击穿;
  2. 焊接工艺:手工焊接时,烙铁头温度≤350℃,焊接时间≤3s(避免过热损坏陶瓷介质);回流焊需符合IPC-A-610标准;
  3. 吸潮防护:未开封电容储存在25℃±5℃、湿度≤60%环境;开封后建议72h内使用,若吸潮需按120℃/24h烘烤后再焊接;
  4. 静电防护:MLCC为静电敏感元件(ESD等级≥2kV),操作时需佩戴防静电手环、使用防静电工作台。

该产品凭借高耐压、宽温稳定、低损耗等特性,可有效解决高压电路中容值漂移、信号衰减等问题,是工业级高压场景的可靠选择。

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.
