TCC0402X5R104K250AT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本信息

  • 品牌:三环电子(CCTC),国内MLCC领域主流制造商,具备完整的研发与生产体系;
  • 产品类型:贴片多层陶瓷电容(MLCC),采用叠层陶瓷工艺实现高容值密度;
  • 型号含义:
    TCC(品牌代码)+ 0402(封装尺寸,0.04英寸×0.02英寸)+ X5R(温度系数)+ 104(容值代码,10×10⁴pF=100nF)+ K(精度代码,±10%)+ 250(额定电压,25V)+ AT(工艺/批次代码);
  • 环保认证:符合RoHS 2.0、REACH法规,无铅无卤,适配全球市场准入要求。

二、关键性能参数

该产品核心参数覆盖通用电路的核心需求,具体如下:

  1. 容值与精度:标称100nF,允许偏差±10%(K档),满足大部分电源滤波、信号耦合的容值稳定性要求;
  2. 额定电压:直流25V,交流额定电压需参考 datasheet(通常为直流额定电压的1/2,即12.5V);
  3. 温度特性:X5R温度系数,工作温度范围-55℃~+85℃,容值变化率≤±15%(相对于25℃基准值),兼顾温度稳定性与容值密度;
  4. 损耗特性:1kHz频率下,损耗角正切值(tanδ)≤2.5%,低损耗适合信号传输场景,避免能量损耗;
  5. 绝缘性能:25℃、额定电压下,直流漏电流≤1μA,长期工作无明显漏电;
  6. 尺寸规格:0402封装,典型尺寸1.0mm(长)×0.5mm(宽)×0.5mm(厚),体积紧凑,适配高密度PCB设计。

三、封装与结构特点

  • 封装适配性:0402封装符合IPC-J-STD-001标准,可直接用于SMT自动化生产线,贴装效率高,适合批量生产;
  • 电极结构:内部采用镍(Ni)电极,外部端电极为“镍/锡”三层结构,焊接兼容性好,可匹配无铅回流焊、波峰焊工艺;
  • 介质材料:X5R陶瓷介质,相比NPO(温度稳定但容值密度低)、Y5V(容值密度高但温度漂移大),是“温度稳定性+容值密度”的折中最优选择,适合通用电路。

四、典型应用场景

该产品因性能均衡、体积小巧,广泛应用于以下领域:

  1. 消费电子:智能手机、平板的电源管理模块(Vcore供电去耦)、音频电路(信号耦合)、蓝牙模块(匹配网络);
  2. 小型家电:智能音箱、路由器、机顶盒的控制板,用于电源滤波抑制高频噪声;
  3. 工业控制:小型PLC、传感器模块的辅助电路,满足-55℃~+85℃的宽温可靠性;
  4. 通信设备:便携式热点、物联网终端的信号处理电路,低损耗保障信号质量。

五、可靠性与质量保障

  • 生产工艺:三环电子采用全自动叠层、印刷、烧结生产线,工艺一致性达行业前列,批次间参数差异≤±2%;
  • 可靠性测试:通过IEC 60384-1、GB/T 2693标准测试,包括:
    • 高温老化:125℃/1000h,容值变化≤±5%;
    • 湿度循环:85℃/85%RH/1000h,绝缘电阻≥10⁹Ω;
    • 机械振动:10~2000Hz/1.5g,无开路/短路;
  • 长期稳定性:额定条件下工作1000h,漏电流无明显上升,满足电子设备5~10年生命周期需求。

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%(≤20V),避免长期过压导致介质击穿;
  2. 温度适配:若环境温度超过85℃,需切换至X7R(-55~+125℃)型产品;
  3. 焊接工艺:回流焊峰值温度控制在230~245℃,时间≤30s,避免热应力损伤陶瓷介质;
  4. 精度升级:若电路需±5%精度,可选用同系列J档产品(TCC0402X5R104J250AT)。

TCC0402X5R104K250AT作为三环电子的通用型MLCC,凭借均衡的性能、紧凑的封装与可靠的质量,是消费电子、工业控制等领域的优选元件,可有效降低电路设计成本与空间占用。

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
