APPLICATION DATA
• Complete range of size/resistance combinations for 120 and 240 volt
compressor motors.
• Rugged silver electrodes well suited for long life pressure contact
mounting.
• Withstand voltage is 2 times Voltage Max. rating.
• Application engineering assistance provided for custom
pellet designs.
T
Vishay Cera-Mite offers a complete line of PTCR
motor start pellets designed for OEM pressure
contact mounting. Compressor and refrigerator
manufacturers, as well as selected HVAC after-
market distributors have chosen to design and
build their own proprietary motor start devices.
Such cost effective units allow for unique mounting
styles, special terminal arrangements, and
combination devices including start capacitors or
overload protectors.

R25 = zero power resistance ± 30% at 25°C; other tolerances available.
RDYN = nominal dynamic (effective) resistance, 120V applied unless otherwise noted.
*High performance ceramic formulation, lower transition temperature provides reduced
power consumption for energy concious applications.
Note: All motor start pellets receive 100% resistance and 100% voltage pulse burn-in
simulating actual motor start-up.
Note: Selected pellets carry UL recognition per File E107611.
Note: Usage requires packaging materials appropriate for maximum pellet surface
temperature of 180°C.
