KTY and possible alternatives
The Alpha Therm PTC series is an excellent alternative to the Philips NXP silicone temperature sensors KTY series. Available in a variety of nominal resistances and tolerances, these sensors are ideal for temperature measurement and control in a variety of applications.
The Alpha Therm PTC series includes models with various nominal resistances and tolerances, including:
Alpha Therm PTC-600with 1025 Ohm nominal resistance at 100°C and tolerances of 3% and 5%.
Alpha Therm PTC-1000 with 1000 Ohm nominal resistance at 25°C and tolerances of 1%, 2%, 3% and 5%.
Alpha Therm PTC-2000 with 2000 Ohm nominal resistance at 25°C and tolerances of 1%, 2%, 3% and 5%.
These sensors are compatible with the following KTY series models:
KTY81/110, KTY81/120, KTY81/121, KTY81/122, KTY81/150, KTY81/210, KTY81/220, KTY81/221, KTY81/222, KTY81/250
