TDK C2012X7R2A103KT020U 多层陶瓷贴片电容(MLCC)产品概述

一、产品基本信息与型号解码

TDK C2012X7R2A103KT020U是一款0805封装工业级MLCC,型号各部分精准对应核心参数,便于快速选型:

  • C2012:TDK对0805英寸封装的公制标识(2.0mm×1.2mm),符合行业贴装标准;
  • X7R:温度系数类别,覆盖-55℃~+125℃宽温范围;
  • 2A:额定直流电压(DC)100V(TDK电压代码:2A=100V,1A=10V、3A=250V);
  • 103:容值标识(10×10³pF=10nF);
  • K:容值精度±10%;
  • T020U:无铅镍锡三层端接(镍底层+镍中间层+锡表层),兼容RoHS/REACH环保要求。

二、核心电气性能参数

该电容的电气指标均通过TDK严苛测试,关键参数如下:

参数 规格值 测试条件 标称容值 10nF(103) —— 容值精度 ±10%(K) 25℃,1kHz,1Vrms 额定DC电压 100V 连续工作电压上限 温度系数(X7R) ±15%(-55℃~+125℃) 相对于25℃容值变化率 损耗角正切(tanδ) ≤2.5% 1kHz,1Vrms,25℃ 绝缘电阻(IR) ≥10⁹Ω 25℃,50V DC,60s

注:125℃时绝缘电阻仍≥10⁸Ω,满足高温场景下的绝缘要求。

三、封装与物理特性

采用0805英寸贴片封装,尺寸紧凑且适配自动化生产:

  • 外形尺寸:长2.0mm±0.2mm,宽1.2mm±0.2mm,厚0.8mm±0.1mm;
  • 端接可靠性:三层无铅端接可承受260℃回流焊3次,无开裂、虚焊风险;
  • 重量:约0.02g,轻量化设计适合高密度电路板布局。

四、温度特性与稳定性

X7R温度系数是该电容的核心优势,平衡了容值稳定性与应用场景:

  • 工作温度范围:-55℃~+125℃,覆盖工业高温(如烤箱、电机旁)与低温(如户外设备)环境;
  • 容值变化:全温区容值波动≤±15%,优于Y5V(±20%)等低成本方案;
  • 对比NPO电容:NPO容值稳定性更高(±0.05%),但容值通常<1nF,而X7R支持10nF中等容值,更适合滤波、耦合。

五、典型应用场景

因电压、容值与温宽的匹配性,该电容广泛用于:

  1. 电源滤波:开关电源输入/输出滤波(市电整流后100V级)、线性电源去耦;
  2. 数字电路去耦:CPU、FPGA、DSP核心芯片的电源去耦,滤除10~100MHz中频噪声;
  3. 信号耦合:音频功放输入耦合、射频LNA旁路;
  4. 工业控制:PLC、传感器接口、电机驱动电路(耐温适配工业环境);
  5. 消费电子:液晶电视、机顶盒的电源与信号处理电路。

六、可靠性与环境适应性

通过多项行业标准测试,确保长期稳定:

  • 高温负荷寿命(THL):125℃、100V DC下工作1000小时,容值变化≤±10%;
  • 湿度负荷寿命(THB):60℃、95%RH、100V DC下工作500小时,性能无衰减;
  • 机械可靠性:振动(10~2000Hz,1.5g)、冲击(1000g,0.5ms)测试后无失效;
  • 环保合规:符合RoHS 2.0、REACH,无铅、无镉、无溴。

七、选型与替换参考

同参数替代型号可参考:

  • 同品牌:TDK C2012X7R2A103KT000N(端接类型不同,性能一致);
  • 竞品:村田GRM21BR61C103KA5D(0805封装,100V,10nF,X7R,±10%);
  • 注意:替换需确认封装、电压、温度系数、精度完全一致,避免性能偏差。

该电容凭借高性价比、宽温稳定性,成为工业与消费电子领域的主流选型。

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
