TCC0204COG0R8C500AT 贴片多层陶瓷电容产品概述

一、产品基本定位与型号解析

TCC0204COG0R8C500AT是三环电子(CCTC) 推出的高频精密贴片多层陶瓷电容(MLCC),专为小型化、高稳定、低损耗的电子电路设计。型号编码清晰对应核心参数:

  • TCC:三环电子品牌标识;
  • 0402:英制封装尺寸(0.04英寸×0.02英寸,公制对应1005封装:1.0mm×0.5mm);
  • COG:温度系数标识(对应IEC标准NP0,温度特性极稳定);
  • 0R8:标称容值0.8pF(“R”代表小数点);
  • 500:额定直流电压50V;
  • AT:产品系列后缀(代表通用高频精密系列)。

二、核心技术参数详解

该电容的关键参数围绕“高频精密”核心设计,具体如下:

  1. 容值规格:标称容值0.8pF,精度达±1%(或±0.008pF),在-55℃~+125℃宽温范围内,容值变化≤±30ppm/℃(即最大变化量≤0.024pF),远优于X7R等温度敏感型电容;
  2. 额定电压:直流50V(AC电压需按峰值降额,建议不超过50V),满足多数中低压高频电路需求;
  3. 损耗特性:1kHz频率下损耗角正切(tanδ)≤0.15%,1GHz射频频段仍保持低损耗(≤0.5%),信号传输失真极小;
  4. 绝缘性能:25℃、10V直流条件下,绝缘电阻≥10¹⁰Ω,抗漏电流能力强;
  5. 机械尺寸:封装厚度约0.5mm(±0.05mm),引脚间距适配标准0402贴装设备,适合高密度电路集成。

三、材料与工艺特点

该电容采用无铅环保陶瓷材料与成熟MLCC工艺,核心优势体现在:

  • 陶瓷介质:选用钛酸锶基COG介质,无极性、温度稳定性优异,避免了X7R类电容的容值温漂问题;
  • 电极结构:内部电极采用银钯合金(Ag-Pd)或镍(Ni),共烧工艺实现多层叠层,保证小容值的一致性与可靠性;
  • 环保合规:符合RoHS 2.0、REACH等国际环保标准,无铅无卤,满足出口与高端应用的环保要求;
  • 工艺精度:流延成型与叠层精度控制在±1μm以内,确保0.8pF小容值的批量一致性。

四、典型应用场景

因温度稳定、高频低损、小型化的特点,该电容广泛应用于以下领域:

  1. 射频通信设备:手机、5G基站、WiFi模块的射频前端(滤波器、振荡器、阻抗匹配网络),需稳定容值避免信号偏移;
  2. 医疗电子:精密监护仪、传感器电路(如血氧仪、心电图仪),宽温环境下保证测量精度;
  3. 工业控制:PLC、伺服驱动器的高频信号处理模块,抗振动冲击能力强;
  4. 消费电子:蓝牙耳机、智能手表、可穿戴设备的小型化电路,节省PCB空间;
  5. 航空航天辅助电路:严苛环境下的低功耗控制电路(部分型号符合AEC-Q200汽车级标准)。

五、性能优势总结

相比普通MLCC,该产品的核心竞争力在于:

  1. 温度稳定性:-55℃~+125℃容值变化可忽略,适合精密测量与高频电路;
  2. 高频低损:射频频段损耗低,提升信号传输效率;
  3. 小型化集成:0402封装适配高密度贴装,降低电路体积;
  4. 高可靠性:多层陶瓷结构抗振动、抗冲击,寿命可达10万小时以上;
  5. 成本可控:三环电子的规模化生产,平衡了性能与成本,适合批量应用。

六、选型与使用注意事项

为保证产品性能与寿命,需注意以下几点:

  1. 电压降额:实际工作电压建议不超过额定电压的70%(即≤35V DC),避免过压损坏;
  2. 焊接工艺:采用回流焊(峰值温度230~245℃,恒温时间≤10秒),禁止手工焊(易损伤陶瓷层);
  3. 存储条件:开封前存储于1535℃、4060%湿度环境,开封后建议12个月内使用完毕;
  4. 静电防护:操作时需接地,避免静电放电(ESD)损坏(敏感电压≤100V);
  5. 应用匹配:适合小容值高频精密电路,不建议用于大容量滤波(如电源滤波需选X7R/X5R类电容)。

该产品凭借稳定的性能与可靠的工艺,成为高频精密电路中替代进口同类产品的高性价比选择,广泛适配消费电子、通信、医疗等多领域需求。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
