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
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.

DISSIPATION FACTOR
• For values greater than 50 pF: see datasheet
• For lower values the dissipation factor is calculated according to the type of ceramic (rated temperature coefficient) under
consideration of the capacitance acc. to EN 130600.
• The dissipation factor as well as the measuring method to be agreed between manufacturer and user for values lower than
5 pF.
