CCTC三环TCC0805X7R681K500DT 贴片多层陶瓷电容(MLCC)产品概述

一、产品核心定位与身份识别

CCTC三环TCC0805X7R681K500DT是一款中低压通用型贴片多层陶瓷电容(MLCC),针对消费电子、通信、工业控制等领域的滤波、耦合、旁路需求设计,适配0805标准贴片封装,核心参数稳定可靠,是高性价比的电路基础元件选型。

产品型号编码解析(结合三环内部规范):

  • TCC:三环MLCC产品系列标识(对应通用型产品线);
  • 0805:英制封装尺寸(公制:2.0×1.25mm,典型厚度1.0mm);
  • X7R:温度系数代码(-55℃~+125℃宽温范围,容值变化±15%);
  • 681:容值编码(68×10¹=680pF);
  • K:精度标识(±10%);
  • 500:额定电压(50V DC,部分厂商编码习惯);
  • DT:三环内部等级代码(对应商业级/工业级双认证)。

二、关键电气参数详解

该产品核心参数覆盖主流中低压电路设计需求,具体如下:

1. 容值与精度

标称容值680pF(681),精度±10%(K级)。此容值属于中容量MLCC(介于100pF小容量与1μF大容量之间),适合:

  • 电源滤波(中频段10kHz~1MHz);
  • 信号耦合(音频、低速数字信号);
  • 旁路电容(抑制电源纹波)。 ±10%精度可满足大多数非精密电路需求,无需额外匹配补偿。

2. 额定电压

50V DC额定电压,属于中低压范畴,直接适配:

  • 12V/24V/36V电源系统(无需降额);
  • 48V系统需按1.2倍降额(实际工作电压≤41.7V),符合工业控制电源规范。

3. 温度特性(X7R核心优势)

X7R是MLCC稳定型温度系数,相比Y5V(高容值但温漂大),其特点:

  • 温度范围:-55℃~+125℃(覆盖户外、工业高温场景);
  • 容值变化:±15%以内(远优于Y5V的-82%~+22%);
  • 损耗角正切(tanδ):典型值≤0.015(低损耗,适合信号电路)。

三、封装与物理特性

采用0805标准贴片封装,适配常规SMT工艺(回流焊、波峰焊兼容),物理特性亮点:

  • 体积紧凑:2.0×1.25mm尺寸平衡容值密度与贴装难度,适合高密度PCB设计;
  • 无铅环保:符合RoHS、REACH指令,采用无铅焊端(Sn-Cu合金);
  • 机械可靠性:多层陶瓷+金属电极结构,抗振动(IEC 60068-2-6)、抗冲击(IEC 60068-2-27)性能满足移动设备/工业现场要求;
  • 焊接兼容性:回流焊温度范围220℃~240℃,无开裂、焊端脱落风险(符合J-STD-020标准)。

四、典型应用场景

因参数均衡、性价比高,广泛应用于以下领域:

1. 消费电子

  • 智能手机/平板:电池管理系统(BMS)滤波、音频接口耦合;
  • 智能家居:智能音箱、开关面板的电源稳压。

2. 通信设备

  • 路由器/交换机:电源模块滤波、数据总线旁路电容;
  • 基站:射频前端辅助滤波(低损耗需求)。

3. 工业控制

  • PLC(可编程逻辑控制器):传感器模块信号滤波;
  • 变频器:电源纹波抑制。

4. 家电产品

  • 电视/空调:电源滤波、遥控电路耦合;
  • 洗衣机:控制板信号稳定。

五、品牌与可靠性说明

CCTC(三环)是国内老牌MLCC制造商,拥有20+年陶瓷电容研发生产经验,产品覆盖:

  • 认证:ISO 9001、ISO 14001、IATF 16949(车规级部分系列);
  • 可靠性验证:
    • 高温寿命:125℃/50V下1000小时,容值变化≤±10%;
    • 湿度测试:85℃/85%RH下500小时,性能无衰减;
    • 老化测试:室温下50V直流老化,漏电流≤1μA。

六、选型与替换建议

若需替换该产品,需匹配核心参数:

  • 封装:0805;
  • 容值:680pF(±10%);
  • 温系:X7R;
  • 额定电压:≥50V;
  • 兼容品牌:国巨CC0805KRX7R9BB681、三星CL0805X7R681K500BN。

注意:精密射频场景需确认替换产品的tanδ≤0.015(与三环该产品一致)。

该产品凭借均衡的参数、可靠的性能及三环的品牌背书,成为中低压电路设计的主流选型之一。

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
