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 titanate
MAIN FEATURES
CLASS 1
Application
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.
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.

application where higher losses and a reduced
capacitance stability are required.
As RFI and safety capacitors.
