TCC0402COG301J500AT 贴片陶瓷电容(MLCC)产品概述

一、产品核心身份标识

TCC0402COG301J500AT是三环电子(CCTC) 推出的一款多层片式陶瓷电容(MLCC),专为高频、精密电子电路设计。型号中各字符对应明确:

  • TCC:三环电子品牌代码;
  • 0402:英制封装尺寸(对应公制1005,即长1.0mm×宽0.5mm);
  • COG:EIA温度系数代码(对应NP0类陶瓷介质,温度稳定性最优);
  • 301:容值编码(有效数字30×10¹=300pF);
  • J:精度代码(±5%);
  • 500:额定电压(50V);
  • AT:产品工艺/封装衍生代码(三环标准商用级规格)。

二、关键性能参数详解

该产品核心参数精准匹配高频精密应用需求,具体如下:

1. 容值与精度

  • 标称容值:300pF(301编码);
  • 精度范围:±5%(J级),满足大多数工业、通信电路的精密滤波/耦合需求;
  • 容值一致性:三环采用多层印刷工艺,批次间容值偏差≤±2%(优于行业平均水平)。

2. 温度特性(C0G核心优势)

C0G(NP0)介质的温度系数为**±30ppm/℃以内**,在-55℃~125℃宽温范围内:

  • 容值变化率≤±0.3%(典型值);
  • 损耗角正切(tanδ)≤0.001(1kHz/25℃),远低于X7R类电容(tanδ≈0.015),适合高频信号传输。

3. 电气安全参数

  • 额定电压:50V DC(适用于低压电路,避免过压击穿);
  • 绝缘电阻:≥10¹⁰Ω(25℃/10V DC),防止漏电流干扰信号;
  • 耐电压:100V DC(60秒,无击穿/闪络),满足短期过压防护。

三、封装与物理特性

0402封装是小尺寸电子设备的主流选择,TCC0402COG301J500AT的物理参数如下:

维度 典型值 公差 长度(L) 1.00mm ±0.20mm 宽度(W) 0.50mm ±0.20mm 厚度(T) 0.50mm ±0.10mm

端电极设计

采用三层复合电极:镍底层(增强附着力)+ 镍中间层(抗氧化)+ 锡表层(无铅回流焊兼容),焊接强度≥2N(拉力测试),可承受3次无铅回流焊(峰值260℃,持续≤10秒)。

四、适用典型场景

该产品凭借C0G的温度稳定性、高精度和小尺寸,广泛应用于以下领域:

1. 通信设备

  • 基站RRU/BBU:射频链路的信号耦合、中频滤波(避免温漂导致的信号失真);
  • 5G终端:手机/平板的射频前端(PA滤波、天线匹配)。

2. 工业控制

  • PLC模拟量输入:传感器信号滤波(±5%精度满足工业级噪声抑制);
  • 伺服电机驱动:功率电路的高频去耦(低损耗减少能量消耗)。

3. 消费电子

  • 智能穿戴:手环/手表的低功耗电路滤波;
  • 音频设备:耳机放大器的信号耦合(低损耗保证音质纯净)。

4. 医疗仪器

  • 小型监护仪:生理信号采集的滤波(高精度避免误诊)。

五、产品优势与价值

  1. 温度稳定性行业领先:C0G介质无明显温漂,替代X7R电容可提升电路长期可靠性;
  2. 小尺寸适配高密度设计:0402封装支持PCB板小型化,满足5G、穿戴设备的空间要求;
  3. 品牌可靠性保障:三环电子拥有30+年MLCC生产经验,产品通过ISO9001、IATF16949(车规级延伸)认证;
  4. 环保合规:符合RoHS 2.0、REACH标准,无铅无镉,适配全球市场。

六、质量与可靠性测试

三环对该产品执行严格的可靠性验证,确保恶劣环境下稳定工作:

  • 高温存储:125℃×1000小时,容值变化≤±1%;
  • 温度循环:-55℃~125℃×1000次,无开路/短路;
  • 湿度老化:85℃/85%RH×1000小时,绝缘电阻≥10⁹Ω;
  • 焊接可靠性:3次无铅回流焊后,端电极无脱落、电容无失效。

该产品是高频精密电路的高性价比选择,平衡了性能、尺寸与成本,适用于从消费电子到工业级的多场景需求。

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
