TCC0402COG0R5B500AT 三环贴片MLCC产品概述

TCC0402COG0R5B500AT是三环电子(CCTC) 推出的一款0402封装贴片多层陶瓷电容(MLCC),针对高频、高稳定、小型化电路需求设计,核心参数聚焦0.5pF小容值、C0G温度系数、50V额定电压,是精密电子系统中常用的基础元件。

一、产品核心身份与型号解析

该型号遵循MLCC行业通用命名规则,各部分含义清晰:

  • TCC:三环电子(CCTC)品牌前缀;
  • 0402:英制封装代码,对应公制1005封装(尺寸1.0mm×0.5mm×0.5mm,典型厚度);
  • COG:温度系数代码(即国际标准NP0),代表容值随温度、电压变化极小;
  • 0R5:容值标识,对应0.5pF(pico法拉);
  • B500:额定电压标识,对应50V直流(DC);
  • AT:产品系列或批次后缀,无特殊电气参数差异。

二、关键电气与物理参数

参数类别 具体指标 备注 容值 0.5pF 典型公差±0.1pF(C0G常规精度) 额定电压 50V DC 交流峰值电压不可超过35V 温度系数 C0G(NP0) ±30ppm/℃(-55℃~+125℃范围) 损耗角正切(tanδ) ≤0.15%(1kHz下) 高频损耗极低 封装尺寸 0402(1005公制) 1.0mm×0.5mm×0.5mm(长×宽×厚) 介质类型 I类陶瓷(NP0) 无极性、无老化效应

三、C0G温度系数的核心技术优势

C0G(NP0)是MLCC中I类介质的典型代表,区别于X7R/X5R等II类介质,其核心优势在于:

  1. 容值超稳定:温度从-55℃到+125℃变化时,容值漂移≤±0.0015%(即0.3%),远优于II类介质的±10%以上;
  2. 电压特性平缓:额定电压内,容值随电压变化可忽略,适合精密偏置电路;
  3. 损耗极低:1kHz下tanδ≤0.15%,高频(如2.4GHz)下损耗仍远低于II类介质,适合射频电路;
  4. 无老化效应:长期使用(如1000小时以上)容值无明显衰减,可靠性更高。

四、0402封装的应用适配性

0402封装是当前小型化电子设备的主流封装,适配场景包括:

  • 高密度PCB设计:如智能手机主板、智能穿戴(手环/手表)、微型传感器模块,可大幅节省布局空间;
  • 焊接工艺兼容:支持回流焊、波峰焊(需特殊夹具),回流焊峰值温度可达260℃以上,符合行业标准;
  • 机械可靠性:虽尺寸小,但陶瓷介质结构稳定,抗振动(10G~20G)、抗冲击性能满足消费电子与工业级要求。

五、典型应用场景

该电容因“小容值+高稳定+小封装”的组合,广泛用于以下场景:

  1. 高频射频电路:蓝牙/WiFi模块、5G Sub-6G天线匹配、射频前端滤波;
  2. 精密振荡电路:晶振负载电容、PLL锁相环滤波、时钟电路匹配;
  3. 小型电子设备:蓝牙耳机、智能手环、微型医疗传感器(如血糖监测);
  4. 工业控制模块:PLC输入输出接口滤波、传感器信号调理电路。

六、可靠性与品质保障

三环电子作为国内知名MLCC厂商,该产品通过多项认证与测试:

  • 环保认证:符合RoHS 2.0、REACH SVHC标准,无铅无镉;
  • 可靠性测试:高温高湿(85℃/85%RH)1000小时、温度循环(-55℃~+125℃)500次,容值变化≤±0.2%;
  • 焊接可靠性:回流焊后剪切强度≥2N,满足IPC-A-610标准;
  • 应用注意事项:避免超过50V额定电压(交流电路需注意峰值电压不超35V),焊接时勿施加机械应力。

七、选型与替换参考

  • 同品牌替代:参数一致的同型号不同批次产品可直接替换;
  • 跨品牌替换:需匹配核心参数,如村田GRM1555C1H0R5CA01D(0402/C0G/0.5pF/50V)、TDK C1608C0G1H5R0J(0402/C0G/0.5pF/50V);
  • 选型要点:若电路对容值精度要求低(如一般去耦),可考虑X7R介质(容值范围更大),但高频/精密场景必须选C0G。

该产品以高性价比、稳定可靠的特性,成为消费电子、通信、工业等领域小型化精密电路的优选MLCC元件。

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
