TCC0402X7R102K101AT 多层陶瓷贴片电容(MLCC)产品概述

一、产品基本信息与核心定位

TCC0402X7R102K101AT是三环电子(CCTC) 推出的通用型多层陶瓷贴片电容(MLCC),采用0402英制封装(对应公制1005,尺寸1.0mm×0.5mm),专为中低压电路的滤波、耦合、旁路等场景设计,平衡了小型化、稳定性与成本效益,适用于消费电子、工业控制等多领域。

二、关键技术参数详解

1. 容值与精度

  • 标称容值:1nF(1000pF),代码标识为“102”(前两位有效数10,第三位为10²倍);
  • 精度等级:±10%(代码“K”),满足大多数通用电路对容值偏差的要求,无需高精度场合的额外成本。

2. 额定电压

  • 直流额定电压:100V;
  • 交流应用换算:交流额定电压≈直流额定电压×0.707(约70.7V),可覆盖100V以内的直流/交流电路。

3. 温度特性

  • 温度系数:X7R(行业标准中温稳定型介质);
  • 工作温度范围:-55℃~+125℃;
  • 容值变化率:≤±15%(典型值±10%以内),优于Y5V等高容值介质,适合宽温环境。

4. 其他核心参数

  • 损耗角正切(tanδ):≤1.5%(1kHz、25℃),信号损耗低;
  • 绝缘电阻:≥10¹⁰Ω(25℃、100V直流),漏电小;
  • 封装尺寸:0402(英制),适合高密度PCB布局。

三、材料特性与性能优势

1. 陶瓷介质与叠层工艺

采用X7R高稳定陶瓷介质,介电常数约2000-3000,通过多层叠层工艺实现高容值密度;内电极采用镍(Ni),符合环保无铅要求,外电极为三层结构(Ni/锡基合金),焊接兼容性强。

2. 核心性能优势

  • 小型化:0402封装缩小PCB占用面积,适配便携式设备、小型化模块;
  • 宽温稳定:-55℃~+125℃范围内容值变化小,避免温度波动导致电路性能漂移;
  • 可靠性高:三环成熟工艺确保耐机械应力(PCB弯曲、振动)、湿热环境下性能稳定;
  • 成本可控:相比NP0(COG)高精度电容,成本降低30%-50%,适合批量通用场景。

四、典型应用场景

  1. 消费电子:智能手机、平板电脑的DC-DC输出滤波、音频信号耦合;
  2. 工业控制:小型PLC、传感器模块的电源旁路、信号滤波(宽温环境适配);
  3. 通信设备:路由器、交换机的电源滤波、射频信号耦合(中低频段);
  4. 电源模块:DC-DC转换器、线性电源的输入/输出滤波(100V以内电压范围);
  5. 车载辅助电路:若符合AEC-Q200标准,可用于中控、仪表盘的低压辅助电路(需确认具体认证)。

五、可靠性与环境适应性

  • 温度循环:通过-55℃~+125℃循环试验(1000次),容值变化≤±10%;
  • 湿热试验:符合IEC 60068-2-60(40℃、95%RH,1000小时),绝缘电阻无明显下降;
  • 机械性能:可承受1mm弯曲半径下的PCB变形,振动试验(10-2000Hz、1.5g加速度)无失效;
  • 环保合规:无铅、无镉,符合RoHS 2.0、REACH等环保指令。

六、选型与使用注意事项

  1. 选型匹配:确认电路额定电压(不超过100V)、温度范围(X7R适用-55~125℃)、精度需求(±10%满足则选);
  2. 焊接控制:回流焊峰值温度240-250℃(时间30-60秒),波峰焊峰值温度250-260℃(时间3-5秒),避免过热开裂;
  3. 降额使用:长期工作在接近100V时,建议降额20%(≤80V),延长寿命;
  4. 存储条件:常温干燥环境(10-35℃、40-60%RH),避免长期暴露高湿度;
  5. 无极性注意:MLCC为无极性电容,焊接无需区分正负极,但需确保焊盘与电极对齐。

该产品凭借小型化、宽温稳定、成本可控的特点,成为通用电路中替代传统插件电容的主流选择,适配多领域的高密度设计需求。

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
