TCC0603X7R473K101CT 贴片多层陶瓷电容(MLCC)产品概述

一、核心参数精准定义

本产品为三环电子(CCTC)出品的0603封装MLCC,核心参数经标准化编码与实测验证,具体如下:

  • 容值:47nF(对应3位数字编码“473”,前两位为有效数字47,第三位为10³倍);
  • 精度:±10%(标识字符“K”,满足多数常规电路的容值偏差需求);
  • 额定电压:100V(标识编码“101”,即10×10¹ V,可覆盖中低压电源系统);
  • 温度系数:X7R(行业通用中温稳定型介质);
  • 封装:0603(英制0.06×0.03英寸,公制1.6mm×0.8mm,适配小型化PCB);
  • 环保标准:符合RoHS 2.0、REACH法规,无铅无卤。

二、封装与结构工艺优势

  1. 小型化封装适配高密度设计
    0603封装体积仅为1.6mm×0.8mm×0.8mm(典型高度),可紧密贴装于PCB,支持智能手机、智能穿戴等便携设备的轻薄化需求,同时适配工业控制模块的高密度布局。

  2. 多层陶瓷结构提升容值密度
    采用低温烧结X7R陶瓷介质,通过多层叠层工艺(最多可达数百层)实现“小体积+中等容值”的平衡,容值密度比单层陶瓷电容提升5~10倍,避免大容值带来的封装过大问题。

  3. 端电极优化提升可靠性
    端电极采用“镍底层+锡镀层”双层结构:镍层增强抗硫化性能,避免长期使用中出现电极氧化失效;锡镀层适配无铅焊接工艺,焊接强度符合IPC标准,可承受多次回流焊。

三、X7R温度系数的应用价值

X7R是本产品的核心介质特性,其定义与优势明确:

  • 温度范围:-55℃至+125℃(覆盖工业、消费电子的典型工作环境);
  • 容值稳定性:全温度范围内容值偏差≤±15%(相对25℃参考值),远优于Y5V介质(偏差±20%-80%),同时容值范围(1nF10μF)比NPO介质(通常≤100pF)更广。

应用适配场景:既适合对容值波动敏感的信号电路(如音频耦合),又能满足电源滤波、IC去耦等中等容值需求,覆盖80%以上常规电子电路。

四、典型应用场景

  1. 电源滤波:开关电源、线性电源的输入/输出滤波(如12V/24V/48V系统),100V额定电压可覆盖多数中低压电源,有效抑制纹波(纹波抑制比≥30dB@1kHz);
  2. IC去耦:微控制器(MCU)、功率MOS管等IC的电源引脚去耦,0603封装可紧密贴装于引脚旁,减少寄生电感(≤1nH),提升高频去耦效率;
  3. 信号耦合:音频信号、射频信号(≤100MHz)的耦合电路,X7R低温漂特性避免信号失真;
  4. 工业控制:PLC、变频器、传感器模块的辅助电路,-55℃~+125℃宽温范围适配工业环境的高低温波动;
  5. 消费电子:智能手机、平板电脑的电源管理模块(PMIC),小型化封装满足设备轻薄化需求。

五、品牌可靠性与选型建议

  1. 三环电子(CCTC)品牌保障
    作为国内MLCC行业主流厂商,产品通过ISO9001、IATF16949认证,可靠性测试包括:

    • 高温老化:125℃/1000h,容值变化≤±5%;
    • 湿度循环:85℃/85%RH/1000h,绝缘电阻≥10¹⁰Ω;
    • 机械振动:10~2000Hz/1.5g,无开路短路。
  2. 选型注意事项

    • 电压降额:建议实际工作电压≤70V(额定电压的70%),延长产品寿命(125℃下寿命可达10⁴h以上);
    • 精度升级:若需±5%精度,可选择同封装同温度系数的“J”精度产品(如TCC0603X7R473J101CT);
    • 温度升级:若工作温度超过125℃,需更换为X8R(-55℃+150℃)或C0G(-55℃+125℃,高精度)介质产品。

六、环保与合规性

本产品完全符合欧盟RoHS 2.0(限制铅、镉、汞等6种有害物质)、REACH法规(SVHC高关注物质管控),以及中国《电子信息产品污染控制管理办法》,可用于出口及国内高端电子设备,无环保合规风险。

本产品以“高可靠性、小体积、宽温稳定”为核心优势,是中低压电子电路中替代进口MLCC的高性价比选择,适配消费电子、工业控制、汽车电子(辅助电路)等多领域需求。

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
