APPLICATIONS:

KT SPECIAL PURPOSE TYPE, EIA CLASS I

APPLICATIONS:

Coefficient.

PERFORMANCE CHARACTERISTICS:

Operating Temperature Range: -30°C to +85°C

Storage Temperature Range: -40°C to +100°C

Dielectric Strength: 150% of rated voltage, charging

current limited to 50mA.

Insulation Resistance: 200,000 megohms or 1000

ΩF

minimum at 25°C.

Corona Limit: 50 picocoulombs at rated AC voltage.

Self Resonant Frequency: Ranges from 50 MHz for small

diameters to 10 MHz for large diameters.

Power Dissipation: Limit to 25°C rise above ambient,

measured on case.

KT Series ceramic material is

specially designed to handle

AC current, due to low

dissipation factor.

Applications where high dv/dt is present will operate at high

the actual circuit for dv/dt greater than 2000V/ microsecond. If

repetitive, it may be necessary to use a series resistor or other

impedance to limit peak currents to safe values.

NOTE: Screw torque limit:

12 inch pounds. Use

#8-32, 3/16" long screw to

prevent bottoming.
