TCC0402COG510J500AT 贴片陶瓷电容(MLCC)产品概述

一、产品标识与核心定位

TCC0402COG510J500AT是三环电子(CCTC)推出的0402封装超稳定型多层陶瓷电容(MLCC),型号各段含义明确:

  • TCC:三环电子品牌前缀;
  • 0402:英制封装尺寸(0.04英寸×0.02英寸,对应公制1.0mm×0.5mm);
  • COG:EIA温度系数代码(对应IEC NP0),代表超稳定温度特性;
  • 510:容值代码(51×10⁰=51pF);
  • J:精度等级(±5%);
  • 500:直流额定电压(50V);
  • AT:产品系列/包装标识。

该产品主打高频低损、宽温稳定、小型化,适配高密度PCB设计的高精度电路场景。

二、关键性能参数详解

1. 容值与精度

  • 标称容值:51pF;
  • 精度等级:±5%(J级),满足工业级、商业级电路的精度需求,无需额外校准;
  • 容值范围:典型值51pF,极限值覆盖48.45pF~53.55pF(±5%偏差)。

2. 温度特性(COG核心优势)

C0G温度系数定义为**≤±30ppm/℃**,在工作温度范围(-55℃~+125℃)内:

  • 容值变化率极小(通常<0.1%),无老化漂移;
  • 介电常数稳定,不受温度变化影响,是高频、精密电路的首选介质。

3. 电压与损耗特性

  • 直流额定电压:50V,可满足中低压电路的功率需求;
  • 高频损耗:DF(损耗角正切)≤0.15%(1kHz/25℃),适合射频、振荡等对损耗敏感的场景;
  • 绝缘电阻:≥10¹⁰Ω(25℃/50V),漏电流极低,适配低功耗电路。

三、封装与物理特性

1. 0402封装优势

  • 尺寸:1.0mm(长)×0.5mm(宽)×0.5mm(高,典型值),体积仅为0805封装的1/4,大幅提升PCB集成度;
  • 贴装兼容性:适配常规SMT设备,支持回流焊、波峰焊(需控制温度);
  • 端电极结构:三层设计(银层+镍层+锡层),可焊性优异,焊接强度符合IPC标准。

2. 材质与结构

  • 介质层:高纯度陶瓷(钛酸钡系),叠层结构实现小体积大容量;
  • 内电极:镍基合金,环保无铅;
  • 外电极:锡铅合金(RoHS compliant),避免铅污染。

四、典型应用场景

该产品因稳定、小体积、低损,广泛应用于:

  1. 射频通信:蓝牙、WiFi、4G/5G模块中的滤波、耦合电容,保障信号低损耗传输;
  2. 精密模拟电路:运放反馈网络、电源去耦电容,减少温漂对信号的影响;
  3. 时钟振荡电路:晶体振荡器(XO)的负载电容,确保振荡频率稳定(C0G的温度稳定性直接影响晶振精度);
  4. 消费电子:智能手环、蓝牙耳机、小型家电的控制电路,适配小型化设计;
  5. 工业控制:PLC、传感器模块的辅助电路,满足宽温(-40℃~+85℃)工作需求。

五、品牌与可靠性保障

三环电子(CCTC)是国内MLCC行业领先厂商,产品通过多项认证:

  • 环保认证:RoHS 2.0、REACH SVHC合规;
  • 可靠性测试:高温存储(125℃/1000h)、温度循环(-55℃~+125℃/1000次)、湿度循环(85℃/85%RH/1000h)等,满足GJB/IEC标准;
  • 一致性:批量生产容值、损耗偏差控制在规格范围内,降低电路设计风险。

六、选型与使用注意事项

  1. 电压降额:实际工作电压建议不超过额定电压的80%(即40V),避免过压击穿;
  2. 焊接温度:回流焊峰值温度≤245℃(持续≤10s),波峰焊温度≤260℃(持续≤5s),防止热应力损坏;
  3. 静电防护:生产/存储需佩戴防静电手环,使用防静电包装,避免ESD失效;
  4. 存储条件:未开封产品存于25℃±5℃、湿度≤60%环境,开封后12个月内使用完毕,剩余密封保存;
  5. 容值匹配:振荡电路需根据晶振参数选负载电容(通常10pF~51pF),该产品51pF适配多数通用晶振。

该产品平衡了小型化、稳定性与成本,是高精度电路设计的可靠选择。

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
