TCC0402COG0R5C500AT 贴片电容产品概述

一、产品基本信息

TCC0402COG0R5C500AT是三环电子(CCTC) 推出的多层陶瓷贴片电容(MLCC),型号命名直接对应核心参数:

  • TCC:三环电子品牌标识;
  • 0402:英制封装尺寸(0.04英寸×0.02英寸,对应公制1.0mm×0.5mm);
  • COG:温度系数(Class 1类陶瓷,等效NP0,超稳定型);
  • 0R5:标称容值0.5pF(“R”替代小数点);
  • 500:额定直流电压50V;
  • AT:工艺/批次标识(具体可参考三环官方 datasheet)。

产品符合RoHS 2.0、REACH环保标准,工作温度范围为**-55℃~125℃**(工业级宽温)。

二、核心性能特点

  1. 超稳定温度特性:C0G(NP0)温度系数使容值在全工作温度范围内漂移≤±30ppm/℃,标称0.5pF的容值偏差仅±0.1pF,满足射频、精密模拟电路对容值一致性的严苛要求;
  2. 低损耗高Q值:高频下(如1GHz)损耗因子(DF)≤0.0005,Q值≥2000,减少信号传输衰减,适合高频滤波、匹配场景;
  3. 中压耐受能力:额定电压50V,实际工作电压可稳定在40V以内(留10V余量),覆盖多数工业控制、通信设备的中低压电路;
  4. 无极性设计:MLCC无正负极区分,焊接无需极性判断,提升生产效率,降低装配错误风险。

三、封装与工艺优势

  1. 小型化封装:0402封装体积仅1.0mm×0.5mm×0.5mm(典型高度),适配智能穿戴、便携医疗、小型射频模块等空间受限场景;
  2. 成熟陶瓷工艺:采用三环自研多层陶瓷叠层技术,电极材料为镍基合金(环保无铅),烧结精度±1μm,确保容值一致性;
  3. 焊接兼容性:支持回流焊、波峰焊(符合IPC-J-STD-001标准),回流焊峰值温度235℃±5℃,焊接后无虚焊、脱落问题。

四、典型应用场景

  1. 射频通信:蓝牙/WiFi模块天线匹配、GPS信号滤波、基站射频前端耦合电容;
  2. 精密模拟电路:运算放大器反馈回路、高精度ADC/DAC滤波、传感器信号调理;
  3. 小型电子设备:智能手环无线充电、便携血糖仪信号滤波;
  4. 测试仪器:示波器探头补偿电容、信号发生器频率校准、频谱分析仪前端滤波。

五、质量与可靠性说明

三环对该产品执行严格可靠性测试:

  • 高温寿命:125℃+额定电压下1000小时,容值变化≤±1%,DF变化≤±20%;
  • 湿度可靠性:85℃/85%RH环境1000小时,绝缘电阻≥10^12Ω;
  • 机械应力:0402封装承受10mm PCB弯曲,无开裂、性能下降;
  • 认证资质:通过ISO9001、UL(部分批次)认证,满足工业级可靠性要求。

六、选型与使用注意事项

  1. 选型核对:需更高精度(如±0.05pF)需确认细分型号;工作电压超40V需换更高额定电压产品;
  2. 焊接规范:回流焊升温速率≤2℃/s,峰值时间≤30s,避免高温开裂;
  3. 静电防护:虽抗静电≥2kV,焊接前仍需静电手环防护;
  4. 存储要求:未开封存于25℃±5℃、湿度≤60%环境,开封后1个月内使用完毕。

该产品凭借稳定性能、小型化封装及高可靠性,成为射频、精密电路领域的主流选型。

Electronic component sourcing availability dashboard with ESD-protected samples

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
