TCC0402X7R104K500AT 多层陶瓷贴片电容(MLCC)产品概述

一、产品基本定位与标识解析

TCC0402X7R104K500AT是三环电子(CCTC) 推出的通用型多层陶瓷贴片电容(MLCC),属于小型化表面贴装元件,专为中低压电子电路的滤波、耦合、去耦等场景设计。型号中各字符的核心含义清晰可辨:

  • TCC:三环电子产品专属标识;
  • 0402:英制封装代码(对应公制1005,即1.0mm×0.5mm);
  • X7R:陶瓷材料类型与温度系数;
  • 104:容值标识(10×10⁴ pF = 100nF = 0.1μF);
  • K:容值精度等级(±10%);
  • 500:额定直流电压(50V);
  • AT:封装细节(通常指编带包装或标准工艺版本)。

二、核心参数与性能特点

1. 容值与精度

标称容值为100nF(0.1μF),精度等级为**±10%(K档)**,无需额外高精度筛选即可直接应用,满足多数通用电路对容值偏差的基础要求。

2. 额定电压与耐压

额定直流电压为50V,可承受短时间过压(通常为额定电压的1.5~2倍),适配50V以下中低压直流电路,避免高压击穿风险。

3. 温度系数与稳定性

采用X7R陶瓷材料,温度特性符合国际通用标准:

  • 工作温度范围:-55℃ ~ +125℃;
  • 容值变化率:±15%以内(相对于25℃基准);
    相比Y5V等低成本材料,X7R的温度稳定性更优,可保证宽温环境下电路性能稳定,避免因温度波动导致的信号失真。

4. 损耗与频率特性

介质损耗角正切值(tanδ)较低(通常<2% at 1kHz),适合高频信号耦合;同时具备较好的频率响应,可覆盖10kHz~100MHz的常用电子电路频段,满足多数消费电子与通信设备的信号传输需求。

三、封装与物理特性

1. 封装尺寸

采用0402英制封装(公制1005),典型尺寸为:

  • 长度:1.0±0.2mm;
  • 宽度:0.5±0.2mm;
  • 厚度:0.5±0.1mm;
    体积小、重量轻,可有效节省PCB板空间,完美适配智能手机、可穿戴设备等小型化产品的紧凑设计。

2. 封装工艺

多层陶瓷叠层结构(镍电极+陶瓷介质),表面贴装设计(无引线),兼容标准SMT工艺(回流焊、波峰焊),焊接可靠性高,适合大规模自动化生产,降低产线不良率。

四、典型应用场景

结合参数特点,该电容主要应用于以下领域:

  1. 消费电子:智能手机、平板电脑、智能手表的电源滤波(去耦电容)、音频信号耦合;
  2. 工业控制:PLC模块、传感器电路的低噪声滤波,宽温环境下性能稳定;
  3. 通信设备:路由器、交换机的射频信号耦合、电源旁路,满足高频传输需求;
  4. 小型家电:智能插座、蓝牙耳机的电源稳压,体积适配紧凑设计;
  5. 汽车电子:车载中控、辅助驾驶模块的低压非安全关键电路(需确认汽车级认证,若为商业级则适用于此类场景)。

五、品牌与可靠性保障

三环电子(CCTC)是国内MLCC领域的主流厂商,该产品具备以下可靠性优势:

  • 环保合规:符合RoHS 2.0、REACH等国际环保标准,无铅无卤,适配全球市场;
  • 可靠性测试:通过高温老化(125℃×1000h)、温度循环(-55℃~+125℃×1000次)、湿度测试(85℃/85%RH×1000h)等,满足IEC 60384-14电子元件标准;
  • 一致性好:批量生产时容值、电压参数偏差小,降低生产端筛选成本,提升产品良率。

六、总结

TCC0402X7R104K500AT是一款高性价比的通用MLCC,兼具小型化、宽温稳定、高可靠性等核心特点,覆盖中低压电子电路的多数通用需求,是消费电子、工业控制等领域的优选元件之一。

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
