TCC0805X7R202K500DT 贴片电容产品概述

一、产品基本信息

TCC0805X7R202K500DT是三环电子(CCTC) 推出的一款0805封装贴片陶瓷电容,属于X7R介质类型,主要承担电子电路中的滤波、耦合、旁路等基础功能。该型号针对中等精度与温度稳定性需求设计,适配SMT(表面贴装技术)生产线,是消费电子、工业控制等领域的常用无源器件,能有效提升电路的电磁兼容性与信号稳定性。

二、核心技术参数

该电容的关键参数可明确对应型号标识与实际性能:

  • 容值:2nF(型号中“202K”表示:20×10²pF=2000pF=2nF);
  • 精度:±10%(“K”为IEC标准精度代码,对应容值偏差范围);
  • 额定电压:50V(型号中“50”关联直流/低频交流电路的耐压阈值,避免过压击穿);
  • 温度系数:X7R(国际标准,对应工作温度范围**-55℃~+125℃**,电容值变化率≤±15%);
  • 封装代码:0805(英制尺寸,公制对应2.0mm×1.25mm)。

三、封装与物理特性

  1. 尺寸规格:采用0805标准贴片封装,公制尺寸为2.0mm(长)×1.25mm(宽)×0.85mm(厚),体积紧凑,适合高密度PCB布局(如手机主板、小型控制器);
  2. 封装类型:无引线表面贴装式,适配回流焊、波峰焊等主流焊接工艺,焊接后焊点可靠性高,抗脱落能力强;
  3. 结构设计:多层陶瓷叠层结构,电极采用镍基合金+锡镀层,降低接触电阻,提升高频信号传输效率。

四、材料与性能特点

X7R陶瓷介质是该电容的核心优势:

  • 温度稳定性:在-55℃至+125℃的宽温范围内,电容值变化控制在±15%以内,满足车载、工业等极端环境需求;
  • 介电性能:介电常数约1000~2000,兼顾电容密度与损耗特性,高频下损耗角正切值(tanδ)≤0.02(典型值),适合信号耦合与滤波;
  • 耐压与绝缘:额定电压50V,绝缘电阻≥10⁹Ω(25℃时),可稳定工作在直流或低频交流电路中;
  • 机械性能:贴片封装抗振动(10~2000Hz,1.5g)、抗冲击(1500g,0.1ms)能力较强,适合移动设备或工业振动场景。

五、典型应用场景

该电容因参数适配性强,广泛覆盖以下领域:

  1. 消费电子:手机、平板的电源滤波(DC-DC转换输出去噪)、音频信号耦合(耳机接口、扬声器驱动);
  2. 工业控制:PLC输入输出接口滤波、传感器信号调理(温度/压力传感器去噪);
  3. 通信设备:路由器/交换机的以太网EMI滤波、电源模块旁路电容;
  4. LED驱动:LED电源纹波抑制、EMC滤波(提升照明稳定性);
  5. 小型家电:电饭煲、加湿器的控制电路滤波(降低噪声干扰)。

六、品牌与可靠性说明

三环电子(CCTC)是国内电子元器件老牌厂商,该型号电容符合RoHS环保标准(无铅、无镉),通过ISO9001质量管理体系认证,批量生产时参数一致性好(容值偏差控制在±8%以内,典型值),可降低电路调试成本。此外,产品经过老化测试(125℃×1000h),长期工作失效率低,适合量产应用。

该型号电容凭借紧凑封装、稳定性能与高可靠性,成为中低端电子设备的高性价比选择,能满足多数常规电路的基础电容需求。

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
