TCC0402X5R475M6R3AT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本信息

TCC0402X5R475M6R3AT是三环电子(CCTC) 推出的一款小型化贴片多层陶瓷电容(MLCC),属于公司常规X5R介质系列产品。型号命名遵循行业通用规则:

  • TCC:三环电子品牌代码;
  • 0402:英制封装尺寸(对应公制1005,即1.0mm×0.5mm);
  • X5R:温度系数介质(-55℃~+85℃,容值变化±15%);
  • 475:容值编码(47×10⁵pF=4.7μF);
  • M:容值精度(±20%);
  • 6R3:额定直流电压(6.3V);
  • AT:生产工艺/系列后缀(区别于其他衍生规格)。

二、核心性能参数

该电容的关键技术指标如下(均符合IEC 60384-14标准):

指标 数值 说明 标称容值 4.7μF(475) 电容核心容量 容值精度 ±20%(M级) 适用于对精度要求不苛刻的电路 额定直流电压(Vdc) 6.3V 连续工作电压上限 温度系数介质 X5R 温度范围-55℃~+85℃,容值变化≤±15% 封装尺寸 0402(1.0mm×0.5mm) 小型化设计,适配高密度PCB布局 工作温度范围 -55℃~+85℃ 覆盖工业级与消费电子典型环境 漏电流(25℃,额定电压) ≤0.1μA 低漏电流保证电路功耗控制

三、材料与结构特点

3.1 介质材料

采用X5R型钛酸钡基陶瓷介质,兼具高介电常数(εr≈2000-3000)与中等容值稳定性:

  • 相比Y5V介质(容值变化±22%),X5R的温度稳定性更优,适合对容值波动敏感的滤波/耦合电路;
  • 相比NPO介质(容值变化±0.05%),X5R的容值密度更高(相同封装可实现更大容值),平衡了容量与稳定性。

3.2 结构设计

  • 内部电极:采用镍(Ni)内电极,替代传统银(Ag)电极,降低成本且提高抗电迁移能力;
  • 外部端电极:三层结构(Ni→Cu→Sn/Pb或Sn),增强焊接附着强度与耐腐蚀性;
  • 叠层工艺:采用高精度叠层技术,层间错位≤±2μm,保证容值一致性与可靠性。

3.3 封装优势

0402封装体积仅为0.5mm³,比0603封装缩小约60%,可显著降低PCB占用面积,适配智能手机、智能穿戴等小型化设备的高密度布局需求。

四、典型应用场景

该电容针对低电压、小型化、中容量电路设计,核心应用场景包括:

  1. 消费电子:智能手机/平板的射频电路旁路、电源滤波(如电池供电模块)、蓝牙/WiFi模块耦合;
  2. 智能穿戴:智能手表/手环的传感器电路去耦、低功耗MCU电源滤波;
  3. 小型家电:遥控器、智能音箱的按键电路滤波、音频信号耦合;
  4. 工业控制:小型传感器模块(如温度/压力传感器)的信号滤波、低电压控制电路旁路;
  5. 汽车电子:车载辅助系统(如仪表盘背光、座椅调节)的低电压电路(≤5V)滤波(需确认是否符合AEC-Q200,三环该系列部分规格通过汽车级认证)。

五、可靠性与环境适应性

5.1 可靠性测试

三环对该产品进行了多项可靠性验证,符合:

  • 高温高湿测试(85℃/85%RH,1000小时):容值变化≤±10%,漏电流≤0.2μA;
  • 温度循环测试(-55℃~+85℃,1000次循环):无开裂、端电极脱落,容值变化≤±8%;
  • 机械振动测试(10~2000Hz,加速度1.5g):无性能衰减,满足消费电子与工业级振动要求。

5.2 环境适应性

  • 存储条件:0℃~40℃,湿度≤60%,开封后建议12个月内使用(避免受潮导致性能下降);
  • 焊接兼容性:支持回流焊(峰值温度230240℃,时间≤30秒)、波峰焊(温度240250℃,时间≤5秒),无热应力失效风险。

六、选型与使用注意事项

  1. 电压降额:实际工作电压建议不超过额定电压的80%(即≤5V),避免直流偏置导致容值衰减(X5R介质在额定电压下容值约下降5%~10%);
  2. 精度适配:±20%精度适合滤波、旁路等功能,若需高精度耦合(如射频电路),建议选择±10%或±5%规格;
  3. 焊接防护:焊接后避免残留助焊剂,建议用异丙醇清洗(温度≤40℃),防止端电极腐蚀;
  4. 静电防护:MLCC为静电敏感元件,操作时需佩戴防静电手环/手套,使用防静电工作台。

总结

TCC0402X5R475M6R3AT是一款高性价比、小型化的MLCC,以X5R介质平衡了容值密度与稳定性,适配低电压电路的滤波、耦合、旁路等需求,广泛应用于消费电子、智能穿戴等领域。三环电子的工艺可靠性保证了产品在复杂环境下的长期稳定运行,是小型化设备设计的优选电容之一。

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.
