TCC0402X7R201K500AT 多层陶瓷贴片电容(MLCC)产品概述

TCC0402X7R201K500AT是三环电子(CCTC) 推出的通用型多层陶瓷贴片电容(MLCC),专为高密度、宽温域的电子电路设计,核心参数覆盖常规电路的滤波、耦合、去耦等核心需求,兼具小型化与可靠性优势。

一、产品基本身份与型号解析

该型号遵循MLCC行业标准命名规则,各段含义清晰:

  • TCC:三环电子品牌代码;
  • 0402:英制封装规格(对应公制1005),即长1.0mm±0.2mm、宽0.5mm±0.2mm;
  • X7R:陶瓷介质类型,对应EIA标准温度特性;
  • 201:容值代码,20×10¹=200pF;
  • K:容值精度等级,±10%;
  • 500:额定直流电压,50V;
  • AT:产品后缀(代表无铅无卤、常规温度特性的通用款)。

二、核心电气参数与应用适配性

1. 容值与精度

容值200pF,精度±10%(K档),属于通用型精度范围,可满足多数电路的滤波、耦合需求(如电源纹波抑制、信号耦合),无需额外高精度匹配成本。

2. 额定电压

额定直流电压50V,远高于常见16V/25V同封装MLCC,具备更高电压冗余:

  • 适配12V/24V系统(如汽车电子、工业控制)时,过压风险显著降低;
  • 可兼容部分36V直流电源场景,无需强制降额使用(降额系数≥1.2时,实际可承受电压≥60V)。

3. 介质特性(X7R)

X7R是MLCC常用介质,核心特性为:

  • 温度范围:-55℃~+125℃(覆盖工业、汽车电子的宽温需求);
  • 容值变化率:±15%以内(温度循环下性能稳定,避免电路参数漂移);
  • 介电常数:约2000~3000(比NPO介质高,同封装可实现更大容值)。

三、封装与结构优势

1. 小型化封装

0402(1005)封装尺寸极小,适合高密度PCB设计:

  • 可减少电路空间占用,适配智能手机、智能穿戴、蓝牙耳机等小型设备;
  • 支持贴片自动化生产,焊接效率高(符合SMT回流焊工艺标准,可承受260℃高温)。

2. 多层陶瓷结构

采用多层叠层工艺,相比独石电容:

  • 容值密度更高(同体积下容值是独石的数倍);
  • 寄生参数更低(ESR、ESL小),适合高频电路(如WiFi、蓝牙模块的信号匹配);
  • 机械强度稳定,抗振动性能优于部分薄膜电容(可承受10g/2000Hz振动测试)。

四、可靠性与环保认证

1. 品牌可靠性

三环电子(CCTC)是国内MLCC领域头部厂商,产品通过:

  • 焊接可靠性测试(符合IEC 60384-1标准,无假焊、虚焊风险);
  • 环境测试(高温老化、湿度循环、温度冲击,满足GJB/GB行业标准);
  • 长寿命设计(平均无故障时间MTBF≥10⁶小时)。

2. 环保合规

全系列符合RoHS 2.0(无铅、无镉、无汞)、REACH(无SVHC高风险物质),适配出口欧美市场及绿色电子设计需求。

五、典型应用场景

该产品因参数均衡、可靠性高,广泛应用于:

  1. 消费电子:智能手机/平板的电源滤波、音频耦合、摄像头模块去耦;
  2. 工业控制:PLC模块、传感器节点、电机驱动电路的电压稳定;
  3. 通信设备:路由器、交换机的高频信号匹配、电源去耦;
  4. 汽车电子:车载中控、音响系统、辅助驾驶传感器的信号滤波(适配12V/24V系统);
  5. 小型电子:智能手环、蓝牙耳机、物联网终端的电路集成。

综上,TCC0402X7R201K500AT是一款参数均衡、性价比高的通用MLCC,兼顾小型化、宽温稳定性与可靠性,可满足多领域电子设备的核心电容需求。

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
