Ceramic Disc, RFI and Safety Capacitors
IN ACCORDANCE WITH IEC RECOMMENDATIONS CERAMIC CAPACITORS ARE SUBDIVIDED
INTO TWO CLASSES:
• CERAMIC CLASS 1 or low-K capacitors are mainly manufactured of titanium dioxide or magnesium silicate
• CERAMIC CLASS 2 or high-K capacitors contain mostly alkaline titanates
• Material categorization: for definitions of compliance please see www.vishay.com/doc?99912
MAIN FEATURES
CLASS 1
CLASS 2
For temperature compensation of frequency
discriminating circuits and filters, coupling and
decoupling in high-frequency circuits where low
losses and narrow capacitance tolerances are
demanded. As RFI and safety capacitors.
As coupling and decoupling capacitors for such
application where higher losses and a reduced
capacitance stability are required.
APPLICATION
As RFI and safety capacitors
High stability of capacitance. Low dissipation
factor up to higher frequencies. Defined
temperature coefficient of capacitance, positive
or negative, linear and reversible. High insulation
resistance. No voltage dependence. High
long-term stability of electrical values.
