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. RESISTANCE 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 aftermarket 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.
