Type H plastic film used as the solid dielectric of a
capacitor results in extremely low power factors. Coupled with a high possible
potential gradient, type H meets a specific need. Type
HC is an inexpensive capacitor which will handle very large
currents of the AC or pulse type.
Temperature Range. -60°C
to +75°C. Full nameplate ratings to 65°C. Derate to 80% nameplate voltage for
operation at 75°C.
Capacitance Tolerance. Standard
capacitance tolerance is plus or minus 10%, 5% and 2% available on special
order.
Test Voltage is 200% DC nameplate voltage for one
minute at 25°C.
Life. Design life of type H
capacitors is 10,000 hours at 65°C. A suitable life test is the application of
120% DC nameplate voltage applied for 1,000 hours at 65°C ambient temperature.
Compliance is indicated with less than two failures of a sample lot of
twelve.
Impregnant. Mineral oil & silicone is the liquid
dielectric.
Salt Spray. All outside surfaces are treated to
successfully withstand a 50 hour salt spray. On request, 100 or 150 hour salt
spray resistance may be obtained.
Immersion. All type
H capacitors are hermetically sealed and designed to pass the
immersion test of MIL-C-25D.
Temperature Coefficient. The
temperature coefficient of type H film impregnated with
silicone fluid is negative 800 PPM/ C.
Applications: Type
H capacitors find their major applications in circuits which
require low-loss, high voltage and high current carrying capacitors.
