TCC0805COG750J500BT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本信息

TCC0805COG750J500BT是三环电子(CCTC)推出的0805封装贴片多层陶瓷电容(MLCC),型号各部分定义明确:

  • TCC:三环电子品牌专属前缀,标识产品源自国内MLCC核心制造商;
  • 0805:英制封装尺寸(对应公制2.0mm×1.25mm),适配常规自动化贴装设备,占用PCB面积小,适合高密度电路设计;
  • COG:EIA温度系数代码(对应IEC标准NP0),代表容值温度稳定性最优的陶瓷介质类型;
  • 750:容值代码(前两位“75”+第三位“0”=75×10⁰),即75pF标称容值;
  • J:精度代码,对应**±5%** 容值偏差,满足多数精密电路的匹配需求;
  • 500:额定电压(50×10⁰),即50V直流额定电压,适用于中低压电路场景;
  • BT:后缀标识(通常为封装形式或包装规格,具体可参考三环官方文档)。

二、核心电气性能参数

该型号电容聚焦稳定、精密、中低压适配,核心参数如下:

  1. 容值与精度:标称容值75pF,±5%精度,无老化效应(C0G介质特性),长期使用容值偏差极小;
  2. 额定电压:50V DC,符合GB/T 26933等行业标准,可承受短时间过载(需参考三环官方降额曲线);
  3. 温度系数:C0G型,容值温度漂移率<±30ppm/℃(-55℃~+125℃工作温度范围),是所有陶瓷电容中温度稳定性最高的类型;
  4. 损耗特性:介电损耗tanδ通常<0.001(1kHz/1Vrms测试条件),高频下损耗仍保持极低水平,适合射频电路。

三、材料与工艺特点

采用多层陶瓷叠层结构+C0G温度补偿介质,兼具体积小、容量稳定、高频特性优异的优势:

  • MLCC叠层工艺:通过多层陶瓷片与内电极交替叠压烧结而成,相比独石电容,相同容量下体积缩小60%以上,适配小型化电路;
  • C0G介质材料:属于低介电常数(εr≈10~50)陶瓷,无压电效应,高频阻抗特性好,适合1GHz以上射频电路;
  • 三环工艺优势:内电极采用镍基合金,与陶瓷介质匹配性佳,减少热应力开裂风险;产品符合RoHS 2.0、REACH等环保标准,无铅无镉。

四、典型应用场景

因容值稳定、精度高、高频损耗低,该型号广泛应用于以下场景:

  1. 高频振荡电路:如晶振负载电容、压控振荡器(VCO)匹配电容,依赖C0G的温度稳定性保证振荡频率精度;
  2. 射频前端电路:滤波器、阻抗匹配网络、天线调谐电路,低损耗特性减少信号衰减;
  3. 精密模拟电路:运算放大器反馈电容、信号滤波电容,±5%精度满足模拟信号调理需求;
  4. 工业控制与汽车电子:中低压辅助电路(如传感器信号采集、电源滤波),宽温范围(-55℃~+125℃)适配恶劣环境;
  5. 消费电子:智能手机、平板的射频模块、时钟电路,小型化封装适配便携设备高密度设计。

五、可靠性与环境适应性

该型号经三环严格可靠性测试,符合行业高可靠标准:

  • 温度适应性:工作温度范围-55℃+125℃,存储温度-40℃+85℃,满足汽车电子、工业现场的宽温需求;
  • 机械可靠性:贴片封装抗振动(10~2000Hz,加速度1.5g)、抗冲击(1000m/s²,持续0.1ms)能力符合IEC 60068-2-6/27标准;
  • 寿命特性:C0G介质无老化,长期使用(10000小时以上)容值变化<±0.5%,可靠性远超X7R等高介电常数电容;
  • 焊接兼容性:支持无铅回流焊(峰值温度<260℃,回流时间<30s),符合电子制造行业环保要求。

六、选型与应用注意事项

  1. 焊接工艺:需控制回流焊温度曲线,避免局部过热导致电容开裂;手工焊接时间<3s,温度<350℃;
  2. PCB布局:高频电路中应靠近负载端放置,减少寄生电感对信号的影响;电源滤波电容需靠近IC电源引脚;
  3. 包装规格:常规为卷盘包装(10000pcs/盘),适配自动化贴装;部分场景提供编带包装;
  4. 替代建议:若需兼容,可选择同封装(0805)、同电压(50V)、同温度系数(C0G)的其他品牌(如村田GRM0805C1H750JA02D),但三环产品性价比优势明显。

该型号凭借稳定的电气性能、高可靠性及小型化设计,成为中低压精密电路的优选MLCC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
