TCC0402X7R472J500AT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本定位与核心类别

TCC0402X7R472J500AT是三环电子(CCTC) 推出的通用型贴片多层陶瓷电容(MLCC),属于X7R介质系列的中低压通用产品。型号命名遵循行业标准:

  • “TCC”为三环电子品牌代码;
  • “0402”对应英制封装尺寸(公制1005);
  • “X7R”为温度系数类别;
  • “472”代表容值(47×10²pF=4700pF=4.7nF);
  • “J”表示容值精度±5%;
  • “500”为额定直流电压50V;
  • “AT”为编带包装规格(典型10000pcs/盘,适配自动化贴装)。
    该产品定位于高密度PCB设计的通用滤波、耦合场景,兼顾小封装与稳定性能,覆盖消费电子、工业控制等多领域。

二、核心性能参数详解

2.1 容值与精度

容值为4.7nF(4700pF),精度等级±5%(型号中“J”标识),满足大多数电路对容值偏差的要求,无需额外高精度补偿。

2.2 电压与温度特性

  • 额定直流电压50V:适用于低至中压电路(实际工作电压建议降额至40V以内,延长寿命);
  • X7R温度系数:工作温度范围为**-55℃~+125℃**,在此区间内容值变化控制在±15%以内,优于Y5V等低价介质,适合温度波动较大的环境(如汽车辅助系统、户外工业设备)。

2.3 封装与物理参数

封装为0402英制尺寸(公制1005),具体物理参数参考三环标准:

  • 长度:1.0±0.2mm;
  • 宽度:0.5±0.2mm;
  • 厚度:0.5±0.1mm;
  • 端电极:无铅锡膏(Sn-Cu-Ni),符合RoHS 2.0环保标准,适配回流焊工艺。

三、品牌可靠性与质量保障

三环电子(CCTC)是国内MLCC领域的主流制造商,拥有超过20年的被动元件生产经验,产品通过以下认证:

  • ISO 9001质量管理体系;
  • IATF 16949汽车电子质量体系(部分系列);
  • RoHS 2.0、REACH环保认证。
    该产品采用多层陶瓷叠层工艺,电极与介质层结合紧密,抗老化性能优异,在额定条件下平均寿命可达10000小时以上,产品一致性符合行业AQL抽样标准。

四、典型应用场景

结合参数与封装特性,TCC0402X7R472J500AT适用于以下场景:

  1. 消费电子:智能手机、平板电脑的电源滤波(如DC-DC转换电路)、音频信号耦合;
  2. 工业控制:小型PLC、传感器模块的信号调理电路、低电压控制回路;
  3. 通信设备:WiFi模块、小型路由器的射频滤波、电源去耦;
  4. 家电产品:智能电视、空调的控制板电源滤波、按键电路耦合;
  5. 汽车电子:仪表盘、车载音响的辅助电路(若需AEC-Q200认证,需确认三环对应等级)。

五、使用与选型注意事项

  1. 电压降额:实际工作电压≤40V(额定电压的80%),避免过压导致介质击穿;
  2. 温度控制:工作环境温度需在-55℃~+125℃之间,超出范围会导致容值漂移或性能下降;
  3. 焊接工艺:回流焊峰值温度建议240℃~260℃,时间≤10秒,避免热应力损坏端电极;
  4. 存储条件:常温(25℃±5℃)、干燥(湿度≤60%RH)环境存储,存储周期≤12个月,开封后建议1个月内使用完毕;
  5. 静电防护:贴片电容为静电敏感元件,需在ESD防护区域操作,避免静电损坏。

六、总结

TCC0402X7R472J500AT作为三环电子的通用型MLCC,以小封装(0402)、宽温稳定(X7R)、中压适配(50V) 为核心优势,兼顾可靠性与成本效益,是高密度PCB设计中电源滤波、信号耦合的理想选择,覆盖消费电子、工业控制等多领域应用需求。

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
