TCC1206X7R223K631FT 贴片多层陶瓷电容(MLCC)产品概述

一、产品核心身份与定位

TCC1206X7R223K631FT是三环电子(CCTC) 推出的工业级高压贴片MLCC,专为中高压电子电路的滤波、旁路、EMI抑制等核心功能设计。型号各段标识清晰对应核心参数:

  • TCC:三环电子产品前缀;
  • 1206:英制贴片封装(公制3216);
  • X7R:温度系数(宽温特性);
  • 223:标称容值22nF(22×10³pF);
  • K:精度±10%;
  • 631:额定电压630V DC(63×10¹V);
  • FT:无铅表面贴装工艺后缀。

二、关键电气性能参数

该电容的电气参数适配中高压电路的常规需求,核心指标如下:

  1. 容值与精度:标称22nF,精度±10%,满足多数工业电路对电容值的控制要求;
  2. 额定电压:630V DC,短期可承受≤1.5倍额定电压(需参考厂商规格书),避免长期过压;
  3. 温度特性:X7R材质,工作温度范围-55℃~125℃,电容变化率±15%以内(行业标准),温度稳定性优于Y5V、Z5U等材料;
  4. 辅助性能:25℃下绝缘电阻≥10⁹Ω,1kHz频率下损耗角正切≤2.5%,无明显寄生电感(贴片封装优势)。

三、封装与物理特性

  1. 封装规格:1206英制封装(长3.2mm×宽1.6mm×厚1.0mm,常规值),符合IPC-J-STD-001贴装标准,适配常规SMT产线;
  2. 端电极:无铅锡银铜(Sn-Ag-Cu)合金,兼容回流焊、波峰焊(波峰焊需控制浸锡时间≤3秒);
  3. 可靠性:封装结构采用多层陶瓷叠层工艺,耐机械振动(符合IEC 60068-2-6振动测试),适合工业现场环境。

四、材料特性与温度稳定性

X7R为钛酸钡基陶瓷材料,介电常数约2000~4000,兼具高容值密度与宽温稳定性:

  • 相比NP0(C0G)材质,成本降低30%以上,容值密度更高;
  • 相比Y5V材质,高温(125℃)下容值下降幅度仅15%(Y5V可达50%),适合户外、工业控制等宽温场景。

五、典型应用场景

该电容因630V高压特性,广泛用于以下领域:

  1. 开关电源:AC-DC电源PFC后端滤波、高压输出端旁路;
  2. LED驱动:高压恒流源浪涌抑制、EMI滤波;
  3. 工业控制:变频器、PLC的高压直流电路去耦;
  4. 通信设备:基站射频模块高压去耦、信号耦合;
  5. 医疗电子:小型监护设备高压电路(需确认医疗级认证)。

六、选型与设计注意事项

  1. 电压降额:实际工作电压建议≤额定电压的80%(504V),避免长期老化;
  2. DC偏置效应:X7R电容受直流偏置影响,630V下实际容值约为标称值的80%~90%,设计需参考厂商DC bias曲线;
  3. 封装替换:若需更高容值(如47nF),可选择1210封装同系列产品;若需更高精度,可切换C0G材质(成本提升);
  4. 贴装工艺:回流焊峰值温度控制在220~240℃,避免过热导致陶瓷开裂。

七、品牌与可靠性保障

三环电子(CCTC)是国内老牌陶瓷电容制造商,该产品符合:

  • 环保标准:RoHS 2.0、REACH;
  • 可靠性测试:125℃下1000小时高温寿命(容值变化≤±10%)、85℃/85%RH下1000小时湿热测试(容值变化≤±10%);
  • 应用认证:部分批次通过UL、VDE认证(需确认具体型号)。

该电容平衡了高压性能、宽温稳定性与成本,是中高压电路设计的高性价比选择。

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
