TCC0603COG3R3B500CT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本属性与命名规则

TCC0603COG3R3B500CT是三环电子(CCTC)推出的Class 1型高精度贴片MLCC,专为高频、精密电路设计。其型号命名遵循行业通用规则,各段含义清晰:

  • TCC:三环电子品牌标识;
  • 0603:英制封装尺寸(对应公制1608,即长1.6mm×宽0.8mm);
  • COG:温度系数代码(等效国际标准NP0,温度系数范围0±30ppm/℃);
  • 3R3:容值标识(3.3pF,“R”替代小数点);
  • B500:精度与额定电压关联(B级精度±0.1pF,500=50V DC额定电压);
  • CT:常规工业级系列后缀。

二、核心电气与物理参数

该电容参数经严格校准,满足高频电路对精度和稳定性的要求:

1. 电气参数

  • 标称容值:3.3pF;
  • 容值精度:±0.1pF(B级);
  • 额定电压:50V DC;
  • 温度系数:COG(-55℃~125℃范围内,容值漂移≤0.05%);
  • 损耗角正切(tanδ):≤0.15%(1kHz、25℃条件下);
  • 绝缘电阻:≥10¹² Ω(25℃、50V DC下)。

2. 物理参数

  • 封装尺寸:0603(英制)/1608(公制);
  • 外形尺寸:长1.6±0.15mm × 宽0.8±0.15mm × 厚≤0.8mm;
  • 引脚间距:0.5mm(典型);
  • 单颗重量:≈0.01g。

三、材料特性与温度稳定性

采用钛酸钡基Class 1陶瓷材料,通过镁、锌氧化物掺杂优化晶体结构,核心特性突出:

  • 宽温稳定:-55℃~125℃范围内容值无明显漂移,适合极端环境;
  • 低损耗:高频下损耗远低于Class 2型电容(如X7R),减少信号能量损耗;
  • 无直流偏置:容值不受工作电压影响,避免偏置导致的性能下降;
  • 高绝缘性:陶瓷材料绝缘电阻高,抗漏电流能力强,适配高压小电流场景。

四、封装形式与可靠性验证

1. 封装设计

  • 0603表面贴装封装,适配主流PCB焊盘(推荐焊盘长1.21.4mm、宽0.60.7mm);
  • 电极采用Ni/Sn镀层,焊接兼容性好,焊点强度高,耐老化性能优异。

2. 可靠性测试

符合RoHS 2.0、REACH环保标准,通过多项行业认证:

  • 温度循环(-55℃~125℃,1000次):容值变化≤0.1%;
  • 耐湿性(85℃/85%RH,1000h):绝缘电阻≥10¹¹ Ω;
  • 焊接耐热性(回流焊峰值260℃,10s):无开裂、剥离;
  • ESD防护:耐受±2kV(人体模型),符合IEC 61000-4-2标准。

五、典型应用场景

因高精度、低损耗特性,广泛应用于:

  1. 高频射频电路:手机、基站、WiFi模块的滤波、耦合、匹配网络;
  2. 精密振荡电路:晶振负载电容、PLL滤波,保证频率稳定性;
  3. 通信设备:光纤收发器、微波系统的信号调理;
  4. 工业控制:PLC、传感器模块的定时/滤波电路;
  5. 消费电子:智能穿戴、蓝牙耳机的射频前端。

六、选型与使用注意事项

1. 选型匹配

  • 确认PCB焊盘与0603封装匹配;
  • 工作电压降额使用(建议≤额定电压80%,即≤40V);
  • 1GHz以下高频电路优先选B级精度。

2. 使用要点

  • 静电防护:佩戴防静电手环,使用防静电工具;
  • 焊接工艺:回流焊温度≤260±5℃,单次焊接≤10s;
  • 存储条件:常温干燥(25±5℃、40%~60%RH),存储期≤2年。

该产品平衡了精度、稳定性与成本,是高频精密电路的高性价比选择。

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
