TCC0805X7R224K500DT 多层陶瓷贴片电容(MLCC)产品概述

TCC0805X7R224K500DT是三环电子(CCTC) 推出的一款通用型多层陶瓷贴片电容(MLCC),针对中容值、中电压场景设计,凭借紧凑封装、稳定性能与可靠品质,广泛适配消费电子、工业控制等多领域应用需求。

一、产品核心身份与定位

该型号属于CCTC常规MLCC产品线,以“平衡性能与成本”为核心定位:既满足多数电子电路对滤波、耦合的基础需求,又通过X7R介质特性兼顾温度稳定性,避免了大容值电容常见的温漂问题。0805封装(2.0mm×1.25mm英制尺寸)适配主流SMT产线,适合小型化设备集成。

二、关键电气性能参数详解

  1. 容值与精度:标称容值220nF(标注“224”,即22×10⁴pF),精度±10%(行业K档标准)——满足非精密信号处理、电源滤波等场景的容值偏差要求,无需额外校准。
  2. 额定电压:50V DC——覆盖低压到中压电路(如12V/24V电源系统、信号驱动电路),若需应对纹波电压,建议按20%降额使用(实际工作电压≤40V),保障长期可靠性。
  3. 温度系数:X7R——这是该型号的核心特性之一:
    • 工作温度范围:-55℃~+125℃;
    • 温度范围内容值变化≤±15%——相比Y5V介质(温漂±20%以上)更稳定,相比NPO介质(高精度但容值偏小)更适合中容值需求,是通用场景的最优平衡选择。
  4. 其他性能:绝缘电阻≥10⁹Ω(25℃,10V DC),损耗角正切tanδ≤0.02(1kHz,25℃),无极性设计(无需区分正负极,安装更便捷)。

三、封装与物理特性

采用0805贴片封装(公制对应2012),尺寸紧凑(长2.0±0.2mm,宽1.25±0.2mm,厚度≤1.0mm),符合IPC标准焊盘设计,可直接兼容主流SMT贴装设备,适合高密度PCB布局。表面为镍锡镀层,焊接兼容性好,无铅工艺符合RoHS 2.0、REACH等环保指令。

四、品牌与可靠性保障

CCTC(三环电子)是国内MLCC领域的资深制造商,该型号经过多重可靠性测试:

  • 高低温循环测试(-55℃~+125℃,循环1000次);
  • 老化测试(125℃,1000小时);
  • 湿度测试(85℃/85%RH,1000小时);
    产品失效率符合工业级标准,可稳定工作于消费电子、工业控制、汽车电子(辅助电路)等场景。

五、典型应用场景

  1. 消费电子:手机、平板、笔记本电脑的电源滤波(去除开关电源高频噪声)、信号耦合(音频、射频信号传递);
  2. 工业控制:PLC模块、传感器电路的抗干扰滤波、控制信号耦合;
  3. 汽车电子:车载音响、仪表盘辅助电路的低压滤波(需确认环境温度≤125℃);
  4. 智能家居:智能音箱、安防摄像头的电源与信号处理电路。

六、选型与使用注意事项

  1. 电压匹配:严禁超过50V DC额定电压,纹波电压需叠加计算后降额;
  2. 温度范围:环境温度超出-55℃~+125℃时,容值偏差会超出规格,需更换对应温区型号;
  3. 精度需求:若需±5%精度(J档),此型号不适用,需选择TCC0805X7R224J500DT;
  4. 焊接工艺:回流焊温度曲线需遵循CCTC推荐参数(峰值温度245±5℃,时间≤10s),避免过热导致电容开裂。

该型号凭借“通用性能+可靠品质+紧凑封装”的综合优势,成为电子工程师在中容值、中电压场景下的常用选型之一,适配绝大多数主流电路设计需求。

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
