TCC0402COG511J500AT 贴片陶瓷电容(MLCC)产品概述

一、产品核心身份与定位

TCC0402COG511J500AT是三环电子(CCTC) 推出的一款高性能多层片式陶瓷电容(MLCC),属于常规低压高精度系列产品。型号编码可直观对应核心参数:TCC为三环品牌标识,0402为英制封装尺寸(对应公制1005,即长1.0mm×宽0.5mm),COG为温度系数类别,511表示容值(51×10¹=510pF),J为精度等级(±5%),500代表额定电压50V,AT为封装/批次细分标识。该产品主要面向对容值精度、温度稳定性要求较高的小型化电子设备。

二、关键技术参数解析

  1. 容值与精度:标称容值510pF(511代码),精度±5%(J档),满足多数电路对电容值的精准匹配需求,无需额外筛选即可用于常规精密场景。
  2. 额定电压:50V直流额定电压,覆盖绝大多数低压电子电路(如3.3V、5V、12V系统),无需降额使用即可保证可靠性。
  3. 温度系数:COG(国际电工委员会IEC标准,对应旧称NP0),温度系数典型值±30ppm/℃,即温度每变化1℃,容值变化不超过0.003%;工作温度范围-55℃~+125℃,宽温域内容值稳定性优异。
  4. 封装尺寸:0402英制封装,体积仅1.0mm×0.5mm×0.5mm(典型厚度),适配高密度贴装工艺,适合小型化设备的空间优化。

三、核心性能特点

  1. 高精度温度稳定性:COG类陶瓷材料的固有特性决定了其容值对温度、电压的敏感性极低,即使在极端温度环境下(如车载、工业现场),容值漂移可忽略,避免因参数变化导致电路性能波动。
  2. 低损耗与高Q值:在射频(RF)、微波频段(如2.4GHz、5GHz)下,介质损耗角正切(tanδ)典型值<0.0002(1kHz下),高Q值保证信号传输损耗小,适合射频前端、振荡电路等对损耗敏感的场景。
  3. 小型化与高可靠性:0402封装采用三环成熟的多层陶瓷叠层工艺,电极与介质层结合紧密,抗冲击振动能力符合AEC-Q200(车规级)标准(部分批次),可满足工业、车载等严苛环境需求;同时符合RoHS、REACH等环保指令,无铅无卤。
  4. 宽电压适配性:50V额定电压覆盖从低功耗便携设备到中等功率工业模块的多数应用,避免因电压不足导致的击穿风险,提升电路设计灵活性。

四、典型应用场景

  1. 射频通信领域:智能手机、WiFi6模块、蓝牙设备的射频前端滤波、匹配网络,利用低损耗特性保证信号完整性。
  2. 精密电子电路:晶振振荡电路、时钟同步电路、ADC/DAC参考电路,依赖COG的高精度稳定容值,保证信号时序与精度。
  3. 小型消费电子:蓝牙耳机、智能手环、智能手表等可穿戴设备,0402封装适配其紧凑的内部空间。
  4. 工业与车载:工业控制PLC模块、车载信息娱乐系统,宽温耐环境特性提升设备在极端温度下的可靠性。
  5. 医疗电子:便携式医疗监测设备(如血糖监测仪),高精度与环保特性符合医疗设备对元件的严格要求。

五、三环(CCTC)品牌保障

三环电子作为国内MLCC行业头部厂商,拥有20余年专业生产经验,产能稳定且覆盖全系列封装与参数;产品通过ISO9001、IATF16949等质量体系认证,部分批次满足AEC-Q200车规标准;支持定制化参数调整,可满足不同客户的差异化需求。

该产品凭借高精度、高稳定性与小型化优势,成为消费电子、通信、工业等领域的常规优选元件,适配多数中低端到中端电路的设计需求。

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
