TCC0805COG270J500BT 多层陶瓷贴片电容(MLCC)产品概述

一、产品基本属性

TCC0805COG270J500BT是三环电子(CCTC) 推出的Class 1类多层陶瓷贴片电容(MLCC),型号命名遵循行业通用规则:

  • 前缀“TCC”为三环品牌标识;
  • “0805”对应英制封装尺寸(公制2012,即2.0mm×1.2mm);
  • “COG”代表温度系数(Class 1类核心特性);
  • “270”表示标称容值(27×10⁰=27pF);
  • “J”为精度等级(±5%);
  • “500”是额定直流电压(50V);
  • 后缀“BT”为生产工艺或批次标识。

该产品针对高频稳定、精密滤波及谐振场景设计,兼顾小型化与可靠性,是工业级、通信级设备的常用无源元件。

二、核心性能参数详解

参数项 具体指标 关键说明 标称容值 27pF 容值无直流偏置效应(Class 1特性) 精度等级 ±5%(J档) 工业级常见精度,满足多数精密需求 额定电压 50V DC 工作电压上限,无过压风险 温度系数 C0G(Class 1) 容值随温度变化可忽略 封装尺寸 0805(2012) 小型化贴片封装,适配紧凑设计 寄生参数 低ESR(<10mΩ)、低ESL(<0.5nH) 降低高频信号损耗

注:Class 1类陶瓷无直流偏置特性,容值不随工作电压变化,这是其区别于X7R等Class 2类电容的核心优势。

三、温度特性与稳定性优势

C0G温度系数是该产品的核心竞争力:

  • 工作温区:-55℃~+125℃(覆盖工业、车载等恶劣环境);
  • 容值变化率:≤±0.3%(部分批次可达≤±0.1%),远优于Class 2类(如X7R的±15%);
  • 老化效应:长期使用容值衰减<0.1%/1000小时,几乎无性能衰减。

这种稳定性使产品可用于对频率漂移敏感的场景(如射频振荡器、滤波器谐振单元),避免因温度变化导致谐振频率偏移、信号失真。

四、封装与机械性能

0805封装具备以下实用特点:

  1. 小型化设计:体积仅2.0mm×1.2mm×0.8mm(典型厚度),适配手机、路由器等小型设备的高密度布局;
  2. 贴片兼容性:支持回流焊、波峰焊等自动化生产工艺,焊接良率≥99.5%;
  3. 机械可靠性:陶瓷基体耐冲击、振动(符合MIL-STD-202振动测试标准),可用于车载、航空等严苛环境;
  4. 低寄生损耗:无引脚设计减少寄生电感(ESL),降低高频电路的信号损耗与噪声干扰。

五、典型应用场景

结合性能参数,该产品广泛覆盖以下领域:

  1. 高频通信:5G基站射频模块、卫星通信收发器、WiFi6路由器的滤波/谐振单元;
  2. 精密电子:医疗监护仪、示波器等测试设备的信号调理电路;
  3. 谐振电路:石英振荡器、LC带通滤波器的谐振电容;
  4. 电源滤波:≤50V直流电源的高频纹波抑制(如工业PLC、伺服驱动器电源);
  5. 消费电子:高端智能终端(如旗舰手机)的射频前端模块。

六、品质与可靠性保障

三环电子(CCTC)作为国内MLCC龙头厂商,该产品通过多重品质认证:

  • 国际标准:符合IEC 60384-1(电子设备用固定电容器)、MIL-STD-123(军用级可靠性标准);
  • 国内标准:满足GB/T 14619(多层陶瓷电容器通用规范);
  • 可靠性测试:覆盖高温存储(125℃/1000小时)、温度循环(-55℃~+125℃/1000次)、湿度加载(85℃/85%RH/1000小时)等,合格率≥99.9%;
  • 长期稳定性:绝缘电阻≥10¹²Ω,容值波动<0.2%/年,满足工业级设备的长寿命需求。

该产品凭借稳定的温度特性、小型化封装及高可靠性,成为通信、工业控制、精密电子等领域的优选无源元件。

Sourcing availability signal

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
