Vaccum capacitors

Vacuum capacitors are made of ceramic shell & vacuum medium, and widely used in communication, broadcasting, industry heating, semiconductor process, medical treatment imaging, and high voltage testing epuipment, being used as tune component…
Main Features: Bear high voltage and current & impact; Small cubage; Big capacitance; Easy fixing.

How to define the model number? take CKTBS1200/35/750 for example  
    C: capacitor
    K:  vacuum(medium)
    T:  ceramic shell
    B:  variable ( if no "B", it means fixed )
    S: water cooling (if no "S", it means it is not water cooling)
