TCC0402COG331J500AT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本信息

TCC0402COG331J500AT是三环集团(CCTC) 推出的高频稳定型MLCC,核心参数与封装匹配如下:

  • 型号定义:TCC(三环品牌前缀)+ 0402(英制封装尺寸:0.04×0.02英寸,公制1.0×0.5mm)+ COG(温度系数,即NP0)+ 331(容值编码:33×10¹=330pF)+ J(精度±5%)+ 500(额定电压50V)+ AT(封装细节/批次标识);
  • 基础参数:容值330pF、精度±5%、额定电压50V、温度系数COG;
  • 认证标准:符合IEC 60384、GB/T 2693,通过RoHS 2.0、REACH环保认证。

二、核心性能特点

1. 宽温下的容值稳定性

COG(NP0)温度系数为**±30ppm/℃**,在-55℃至125℃的宽温范围内,容值变化可忽略(实际测试变化率≤0.1%),解决了普通陶瓷电容温漂导致的性能波动问题。

2. 低损耗与高频适配

介质损耗角正切值(DF)典型值≤0.15%,高频(1MHz)下阻抗特性稳定,适合100MHz以内的射频、振荡电路,避免信号失真或能量损耗。

3. 小型化与贴装兼容性

0402封装体积仅1.0×0.5×0.5mm(典型),适配便携式设备的高密度布局;兼容常规SMT贴装工艺(贴装偏差允许±0.05mm),可实现自动化批量生产。

4. 可靠性与耐压设计

额定电压50V满足大部分低压电路需求,MLCC无极性结构抗干扰能力强,长期工作(1000小时@125℃)容值漂移≤0.5%,符合工业级可靠性要求。

三、典型应用场景

1. 高频振荡与时钟电路

作为晶振、压控振荡器(VCO)的负载电容,利用COG的温度稳定性保证振荡频率精准(如手机射频模块的时钟源),避免温漂导致的通信误码。

2. 信号滤波与耦合

  • 滤波:电源纹波抑制(如5V/3.3V电源的旁路滤波)、射频电路杂波过滤;
  • 耦合:音频/射频信号耦合(如蓝牙耳机的信号传输),低损耗特性保证信号完整性。

3. 定时与谐振电路

在RC定时电路(如MCU复位电路)、LC谐振电路(如射频滤波器)中,稳定容值确保定时精度(误差≤0.5%)和谐振频率稳定。

4. 消费电子与工业控制

  • 消费电子:手机、平板、智能穿戴的传感器接口、逻辑电路旁路;
  • 工业控制:PLC模块、传感器节点的低温环境(-40℃)下的信号调理电路。

四、选型与应用注意事项

1. 电压裕量设计

实际工作电压需低于额定电压50V,建议保留10%-20%裕量(如工作电压≤40V),避免过压导致电容击穿或老化加速。

2. 温度范围匹配

若应用环境超出-55℃125℃(如高温航空场景),需更换其他温度系数电容;工业场景(-40℃85℃)本产品完全适配。

3. 贴装工艺要求

0402封装对贴装精度要求较高,需使用高精度贴片机(如富士NXT系列),避免桥连、立碑等缺陷;回流焊温度需符合三环推荐曲线(峰值245℃±5℃)。

4. 精度需求确认

本产品为±5%精度(J档),若应用需更高精度(如≤±1%),需选择F档(±1%)或更高级别,但成本会相应提升。

五、品牌与质量保障

三环集团(CCTC)是国内MLCC行业龙头,TCC系列产品采用自主研发的介质材料,批量一致性好(容值离散度≤0.3%),产能稳定(月产能超10亿只),可满足中小批量至大规模生产需求;产品提供1年质保,支持样品测试与技术咨询。

该产品凭借稳定的温度特性、低损耗和小型化优势,成为消费电子、工业控制等领域高频电路的主流选型之一。

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
