TCC1206X7R123K102FT 产品概述

一、产品简介

TCC1206X7R123K102FT 为三环(CCTC)系列高压多层陶瓷贴片电容器,封装为 1206(约 3.2 × 1.6 mm),标称电容量为 12 nF,容差 ±10%,额定直流电压 1 kV,介质材料为 X7R(II 类介质)。该器件在中高压、小型化电路中提供良好的电容量密度与稳定性,适合需要高工作电压且对体积和成本有要求的旁路、耦合和高压滤波场合。

二、主要参数

  • 品牌:CCTC(三环)
  • 型号:TCC1206X7R123K102FT
  • 封装:1206(约 3.2 × 1.6 mm)
  • 容值:12 nF(123 标识)
  • 精度:±10%(K)
  • 额定电压:1 kV DC
  • 介质:X7R(温度系数类 II)
  • 温度范围:典型 -55°C 至 +125°C
  • 温度特性:-55°C 至 +125°C 范围内容量变化通常在 ±15%(X7R 规范)
  • RoHS 符合性:常见商规符合(出厂请以实际合格证为准)

三、性能特点

  • 高电压等级:1 kV 的额定电压使其能够在高压直流回路、脉冲电路及高压偏置应用中直接使用,减少串联器件数量,简化设计。
  • 良好容量密度:X7R 介质相比 I 类(COG)具有较高的介电常数,在相同体积下可实现更大电容量,适合容量需求较大的设计。
  • 温度稳定性适中:X7R 在 -55°C 至 +125°C 下的容量变化受控(通常 ±15%),对一般电子系统的滤波、旁路应用足够稳定。
  • 体积与可焊性:1206 封装在自动贴装与回流焊工艺下良好匹配,便于批量生产与装配。
  • 成本效益高:相较于 C0G/COG 高稳定介质,X7R 在容量/体积/成本间具有更优的折衷,适合对稳定性要求不极端但对容量和成本敏感的场景。

四、典型应用

  • 电源去耦与旁路(高压电源侧、中高压模块)
  • 高压直流耦合/隔直电路(如 HV 偏置或探测器前端)
  • 高频滤波元件(EMI 抑制、输入输出滤波)
  • 脉冲电路与能量存储场合(需注意介质损耗和功率承受能力)
  • 仪表及传感器前端(要求高压隔离且体积受限的场合)

五、使用建议与注意事项

  • 电压降额:虽然器件额定 1 kV,但长时间在额定电压下工作会加速介质老化并带来显著电场依赖性和温漂。建议在关键可靠性或寿命敏感的设计中对电压进行适度降额(如 50%~80%),以提高稳定性与寿命。
  • 直流偏置影响:X7R 介质存在显著的 DC 偏置效应,施加高偏置电压时电容量会下降,设计时应做 DC 偏置引起的容量下降评估,必要时选用更大标称容量或串并联组合。
  • 温度影响:X7R 在极端温度下仍会有容量变化(最多可达 ±15%)。对于对频率、相位或定时高度敏感的电路(如高 Q 谐振、精密定时),建议采用 C0G/COG 类 I 型电容器。
  • 焊接与回流:遵循厂商给出的回流焊工艺规范进行焊接,避免过高温度和过长加热时间以防封装或电极层损伤。对盘装和储存也遵循湿敏级别及烘干要求。
  • 串并联设计:在高压应用中,可通过串联多个更低电压等级电容或并联多个器件以调节总容量、分散应力或改善 ESR/ESL,但应考虑电压均衡(如分压电阻)和热分布。

六、可靠性与选型提示

  • 与 C0G/COG 相比:X7R 提供更高的容值密度但温度、频率和电场依赖性较大。对稳定性要求极高的滤波器、谐振器、计时电路优先选用 C0G;对去耦、旁路、耦合类且关注体积/成本者可优先选用 X7R。
  • 可靠性验证:在关键应用(高压、脉冲或医疗/航空/计量类)中,建议进行加速老化、温度循环及高压长期稳态测试,以确认在实际工况下的表现。
  • 采购与替代:选型时注意实际出货数据表(datasheet)中的温度特性曲线、DC 偏置曲线与老化信息,以保证在目标工况下满足性能需求。若需更高稳定性可考虑同封装的 C0G 系列;若需更大容量可考虑更大封装或不同介质。

总结:TCC1206X7R123K102FT 是一款面向中高压、小型化场景的 12 nF/1 kV X7R 多层陶瓷贴片电容器,在电容量密度与成本之间有良好折衷,适合去耦、滤波与高压耦合等应用。选型时需关注 DC 偏置、温度特性与降额策略,以保证长期可靠性和电气性能符合系统要求。

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.
