TCC0805X7R123K500DT 贴片陶瓷电容(MLCC)产品概述

TCC0805X7R123K500DT是三环电子(CCTC)推出的通用型多层陶瓷电容(MLCC),针对低压电路的滤波、耦合、旁路核心需求设计,兼具小体积、宽温稳定性与高可靠性,广泛适配消费电子、汽车电子、工业控制等多领域应用。

一、产品基本信息

该型号为三环电子标准系列MLCC,命名遵循行业通用规则:

  • TCC:三环电子(CCTC)品牌代码;
  • 0805:英制封装尺寸(对应公制2012,长×宽≈2.0mm×1.2mm);
  • X7R:介质材料类型,代表宽温特性;
  • 123:容值代码(12×10³pF=12nF);
  • K:容值精度等级(±10%);
  • 500:额定直流电压(50V);
  • DT:封装工艺与批次标识(三环内部工艺规范后缀)。

产品采用无铅环保电极与介质材料,符合欧盟RoHS 2.0及无卤要求,可直接用于出口及高端环保型设备。

二、关键技术参数

  1. 容值与精度:标称容值12nF,精度±10%(K档),满足多数通用电路对容值偏差的要求;
  2. 额定电压:直流50V,稳定适配≤50V直流低压场景;
  3. 温度特性:X7R介质,工作温度范围-55℃~+125℃,容值变化率≤±15%(1kHz测试条件);
  4. 封装尺寸:0805英制封装,典型尺寸:长2.0±0.2mm,宽1.2±0.2mm,厚度1.0±0.1mm;
  5. 损耗特性:1kHz下损耗角正切(tanδ)≤0.01,信号损耗低,适合高频滤波;
  6. 可靠性:通过高温存储(125℃×1000h)、温度循环(-55℃~+125℃×1000次)等行业标准测试,失效率符合GJB/IPC规范。

三、核心特性优势

  1. 宽温稳定性突出:X7R介质平衡了NPO(容值稳定但容值上限低)与Y5V(容值高但温度稳定性差)的缺陷,-55℃至+125℃范围内容值偏差≤±15%,适配车载、工业等极端温度场景;
  2. 小体积适配小型化:0805封装实现12nF容值,相比1206封装节省30%以上PCB面积,满足手机、智能穿戴等便携设备的小型化需求;
  3. 可靠性与一致性:三环采用成熟多层共烧工艺,电极与介质层结合紧密,批量生产一致性好,避免同一批次内容值偏差过大;
  4. 环保与焊接兼容:无铅锡银铜电极适配回流焊、波峰焊,焊接温度窗口宽(220℃~260℃),不易出现虚焊、爆板;
  5. 成本效益平衡:相比高容值高精度NP0/K档MLCC,X7R介质的该型号在满足通用需求的前提下,成本更具竞争力。

四、典型应用场景

  1. 消费电子:手机、平板、智能手表的电源滤波(电池管理系统)、信号耦合(音频/射频电路)、数字电路去耦;
  2. 汽车电子:车载中控、倒车雷达、胎压监测的传感器电源滤波,适配车载-40℃~+85℃环境;
  3. 工业控制:PLC、变频器的电磁干扰抑制滤波、电源模块旁路;
  4. 通信设备:路由器、交换机的射频耦合、电源滤波,支持1kHz~100MHz频段信号处理;
  5. 智能家居:智能音箱、安防摄像头的稳压滤波、信号降噪耦合。

五、封装与可靠性说明

该产品采用0805贴片封装,镀锡电极(Sn/Ag/Cu),焊接注意事项:

  • 回流焊需符合IPC-J-STD-020标准(峰值温度≤260℃,升温速率≤3℃/s);
  • 波峰焊浸锡时间≤3s,避免介质层受热开裂;

可靠性方面,三环提供1年质保,批量应用前建议通过ESD、振动(10Hz~2000Hz)测试验证,确保符合终端设备要求。

TCC0805X7R123K500DT凭借宽温稳定、小体积、高可靠特性,成为通用低压电路替代电解电容的理想选择,适配多行业小型化、高可靠设计需求。

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
