TCC0402X5R474K100AT 贴片陶瓷电容(MLCC)产品概述

一、产品基本定位

TCC0402X5R474K100AT是三环电子(CCTC) 推出的通用型多层陶瓷贴片电容(MLCC),采用0402小型化封装,专为低电压、高密度电路设计,可满足多数消费电子、便携式设备及物联网终端的滤波、耦合、去耦等基础电容需求。该产品属于X5R介质系列,平衡了温度稳定性与成本效益,是批量应用的高性价比选择。

二、核心参数详解

该产品的核心参数明确了其适用范围,关键指标如下:

  1. 容值:470nF(即474pF,容值代码“474”表示47×10⁴pF),满足中容量滤波、耦合需求,避免小容值电容并联带来的空间浪费;
  2. 精度:±10%(通用级精度),适用于非高精度要求的电路(如电源滤波、普通信号耦合),无需额外校准;
  3. 额定电压:10V(直流额定电压),适配3.3V、5V等低电压供电系统,交流场景下需注意峰值电压不超过额定值(如有效值≤7V);
  4. 温度系数:X5R,定义为**-55℃至+85℃** 温度范围内,容值变化≤±15%,相比NP0高频介质更适合中容量场景,温度稳定性优于Y5V等低价介质;
  5. 封装:0402(英制尺寸:0.04英寸×0.02英寸,公制约1005:1.0mm×0.5mm),是当前小型化电路的主流封装之一。

三、封装与工艺特点

  • 封装设计:0402贴片采用两端矩形电极,典型尺寸为1.0±0.1mm×0.5±0.1mm×0.5±0.1mm,适配高密度PCB布局,可减少电路空间占用30%以上(对比0603封装);
  • 制造工艺:采用多层陶瓷叠层技术,介质层为X5R型钛酸钡基陶瓷,电极材料为镍基合金(无铅环保),叠层结构保证容值一致性(同批次容值离散度≤5%);
  • 焊接兼容性:符合RoHS 2.0及REACH标准,支持回流焊(推荐峰值温度245℃±5℃,时间≤10s)、选择性波峰焊,焊接后电极无脱落、虚焊风险;
  • 机械强度:陶瓷介质与电极的结合强度符合IEC 60384-1标准,可承受0.5mm的PCB弯曲应力(常规组装要求)。

四、典型应用场景

结合参数特性,该产品适用于以下场景:

  1. 便携式电子:智能手机、智能手表、蓝牙耳机的电源滤波(电池供电回路)、信号耦合(音频辅助电路);
  2. 消费电子:机顶盒、路由器、电视遥控器的信号处理电路去耦、电源稳压滤波;
  3. 物联网终端:传感器节点(温湿度、运动传感器)的低电压供电滤波、通信模块辅助电路;
  4. 工业控制:小型PLC、远程IO模块的辅助电源滤波、数字电路去耦;
  5. 汽车电子(低功耗):车载USB接口、仪表盘低电压显示电路(需确认使用环境温度不超过+85℃)。

五、品牌与可靠性说明

  • 品牌背景:三环电子(CCTC)是国内MLCC领域核心制造商,拥有20余年研发生产经验,产品覆盖通用、高频、高压系列,服务于华为、小米等国内外企业;
  • 可靠性测试:经过高温储存(125℃×1000h)、温度循环(-55℃~+85℃×500次)、湿度循环(85℃/85%RH×500h) 等测试,失效率≤0.1%(批量应用统计);
  • 质量认证:获得ISO 9001、RoHS 2.0、REACH认证,可满足出口及国内高端客户要求。

六、选型优势总结

  1. 小型化优势:0402封装适配高密度PCB,尤其适合便携式设备的空间限制;
  2. 温度稳定性:X5R介质在宽温区容值变化小,避免环境波动影响电路性能;
  3. 成本效益:±10%通用精度平衡性能与成本,批量采购单价低;
  4. 低电压适配:10V额定电压覆盖多数低电压电路,无需降额使用;
  5. 品牌保障:三环CCTC的成熟工艺减少失效风险,提升项目稳定性。

该产品是低电压、小型化电路的通用选择,可覆盖多数消费电子及物联网终端的电容需求。

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
