TCC0402COG0R9B500AT 贴片多层陶瓷电容(MLCC)产品概述

一、产品核心定位与品牌背景

TCC0402COG0R9B500AT是三环CCTC推出的一款高频小容值、高稳定型贴片多层陶瓷电容(MLCC)。三环作为国内MLCC领域的资深制造商,专注于高可靠电子元器件的研发与生产,该产品针对对容值精度、温度稳定性、低损耗要求严苛的电路设计,是射频、振荡器、精密电子等领域的优选元件。

二、关键电气参数与性能特性

1. 核心电气参数

  • 标称容值:0.9pF,精度典型为±0.1pF(符合C0G类电容的高精度标准);
  • 额定直流电压:50V(直流应用场景,交流应用需确认峰值电压不超过额定值);
  • 温度系数:C0G(即国际标准NP0),在-55℃~125℃范围内,容值变化率≤±30ppm/℃(约±0.027pF),几乎无温漂;
  • 损耗角正切:≤0.15%(1kHz、25℃条件下),低损耗特性适配高频信号传输。

2. 核心性能优势

  • 容值稳定性:无老化效应,长期使用容值漂移极小,适合精密电路的长期可靠性要求;
  • 低噪声特性:陶瓷介质纯度高,寄生噪声低,可满足医疗、传感器等敏感电路的信号质量需求;
  • 高频适应性:小尺寸封装+低寄生电感/电阻,谐振频率典型值>10GHz,适配射频前端等高频场景。

三、封装与物理特性

1. 封装规格

采用0402英制封装(对应公制尺寸:1.0mm×0.5mm×0.5mm,误差±0.1mm),符合IPC-A-610电子组装标准。

2. 结构与材料

  • 介质层:高纯度C0G陶瓷(钛酸钡基,温度稳定性优异);
  • 电极层:镍(Ni)电极(无铅设计,符合RoHS指令);
  • 焊端:锡铅或无铅焊端(可根据客户需求定制),适配回流焊、波峰焊工艺。

3. 物理参数

  • 典型重量:≈0.002g;
  • 焊端尺寸:焊盘宽度0.3mm±0.1mm,确保焊接可靠性。

四、可靠性与环境适应性

1. 焊接可靠性

符合J-STD-020标准,260℃回流焊(3次循环)后,容值变化≤±0.05pF,绝缘电阻≥10^10Ω,无开裂或性能衰减。

2. 环境适应性

  • 温度循环:-55℃~125℃,500次循环后,容值变化≤±0.05pF;
  • 湿度测试:85℃/85%RH环境下1000小时,绝缘电阻仍≥10^10Ω;
  • 机械可靠性:PCB弯曲半径10mm时,电容无开裂、电极脱落等问题。

3. 寿命特性

额定电压下,125℃环境中连续工作1000小时,容值变化≤±0.1pF,满足工业级产品的长寿命需求。

五、典型应用领域

  1. 射频与无线通信:蓝牙5.0/WiFi 6模块、射频前端(RF Front-end)的匹配电容、滤波电容;
  2. 振荡器电路:晶体振荡器(XO)、压控振荡器(VCO)的频率微调电容;
  3. 精密电子设备:医疗监护仪(低噪声信号耦合)、工业传感器(温漂敏感的信号处理);
  4. 消费电子:智能手机天线匹配、智能穿戴设备的高频电路;
  5. 汽车电子(辅助):车载通信模块(-40℃~85℃宽温环境)。

六、应用与选型注意事项

  1. 电压降额:直流应用建议降额至额定电压的70%以下(即≤35V),避免过压击穿;交流应用需计算峰值电压(Vpeak=Vrms×√2),确保Vpeak≤50V;
  2. 焊接工艺:回流焊温度曲线需遵循三环推荐(预热区150℃180℃,120s内;回流区220℃245℃,60s内),避免局部过热导致电容开裂;
  3. 静电防护:MLCC为静电敏感元件(ESD等级Class 1A,≤100V),操作需佩戴静电手环、使用防静电工作台;
  4. 存储条件:常温(15℃~35℃)、干燥(湿度≤60%)环境存储,开封后建议1个月内使用完毕,避免焊端氧化;
  5. 容值匹配:若电路需更大容值(如>1pF),可选择三环C0G系列其他规格(如TCC0402COG1R0B500AT),或根据温漂要求切换至X7R等温度系数。

该产品凭借高稳定、低损耗、小尺寸等优势,可有效满足各类精密电子电路的设计需求,是替代进口同类产品的高性价比选择。

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
