TCC0402COG470J500AT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本信息

TCC0402COG470J500AT是CCTC三环电子推出的I类贴片多层陶瓷电容(MLCC),型号各段定义清晰:

  • TCC:三环电子品牌前缀;
  • 0402:英制封装尺寸(对应公制1005,即1.0mm×0.5mm×0.5mm典型厚度);
  • COG:EIA标准温度系数(商用代号,对应IEC I类陶瓷);
  • 470:容值代码(47×10⁰=47pF);
  • J:容值精度等级(±5%);
  • 500:直流额定电压(50V);
  • AT:封装/批次标识(无特殊电气差异)。

三环电子作为国内MLCC主流厂商,该型号采用高精度叠层印刷工艺,一致性优于行业平均水平,适用于批量量产场景。

二、核心电气性能参数

参数 数值 测试条件 标称容值 47pF 室温(25℃) 容值精度 ±5%(J级) EIA标准精度等级 额定电压 50V DC 直流工作电压上限 温度系数 C0G(NP0) 全温区容值变化≤±30ppm/℃ 工作温度范围 -55℃~125℃ 符合工业级温度要求 损耗角正切(tanδ) ≤0.15% 1kHz、25℃测试 绝缘电阻(IR) ≥10¹⁰Ω 50V DC、25℃测试 谐振频率 典型1.5GHz左右 高频应用参考值

三、C0G温度系数特性解析

C0G是I类陶瓷电容的核心标识,区别于X7R(II类)、Y5V(III类)的关键优势:

  1. 温度稳定性极致:全温区(-55~125℃)容值变化≤±30ppm/℃,几乎不受温度影响,适合精密频率控制;
  2. 无直流偏置效应:容值不会因施加直流电压而漂移(II类电容典型偏置率可达10%以上);
  3. 低损耗高频适配:介电损耗极小,高频下信号衰减可忽略,满足射频、微波电路需求;
  4. 长期可靠性:无老化效应,容值随时间变化≤0.1%/1000小时,适合医疗、工业等长寿命场景。

四、典型应用场景

该型号凭借高稳定、小体积特点,广泛用于以下领域:

  1. 高频振荡电路:作为石英晶振的负载电容,保证手机、路由器时钟频率精度(±10ppm以内);
  2. 射频(RF)匹配网络:5G基站射频前端、WiFi6模块的阻抗匹配,降低信号反射损耗;
  3. 精密滤波:医疗监护仪、工业传感器的低噪声滤波,避免温度变化导致滤波截止频率偏移;
  4. 通信核心模块:光纤收发器、卫星导航设备的信号调理电路,适配高频高稳定需求;
  5. 小型化消费电子:智能手表、蓝牙耳机的时钟电路,满足0402封装的高密度布局要求。

五、可靠性与环境适应性

  1. 工艺与环保:采用无铅无卤陶瓷材料,符合RoHS 2.0、REACH标准;叠层印刷精度±1μm,减少内部缺陷;
  2. 焊接可靠性:兼容回流焊(预热150180℃/60120s,峰值240260℃/1030s)、波峰焊,焊接后无开裂/虚焊;
  3. 机械强度:抗振动(10~2000Hz,1.5g加速度)、抗冲击(1000g/0.1ms)符合MIL-STD-202标准;
  4. 存储条件:常温(15~35℃)、干燥(湿度≤60%)环境下存储寿命≥2年,开封后建议3个月内使用。

六、选型与使用注意事项

  1. 静电防护:MLCC为静电敏感元件(ESD等级≤200V),操作需佩戴防静电手环、使用防静电工作台;
  2. 电压降额:实际工作电压建议不超过40V(额定电压80%),延长产品寿命;
  3. 封装适配:0402封装需注意贴片机分辨率(≥±0.05mm),避免贴装偏移;
  4. 温度限制:避免工作温度超过125℃,否则可能导致容值漂移、绝缘电阻下降;
  5. 批量验证:首次批量应用前建议做100pcs抽样测试(容值、损耗、焊接可靠性),确保一致性。

TCC0402COG470J500AT作为三环C0G系列的主流型号,兼具高稳定性与成本优势,是替代进口同规格产品的优质选择,广泛覆盖高频精密电子领域的多样化需求。

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
