FAQ: Is the PTC series also available in SMD design (SOT23)?
The PTC series is not available in SOT23 design and is not being developed.
As an SMD alternative to the KTY82, we offer our CRFC series, which has a different characteristic, but is significantly better in terms of temperature range, long-term stability, accuracy and response time. In addition, the CRFC series is cost-optimized.
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
- KTY82/110, KTY82/120, KTY82/121, KTY82/122, KTY82/150, KTY82/151, KTY82/210, KTY82/220, KTY82/221, KTY82/222, KTY82/250, KTY82/251, KTY82/252
- KTY83-1, KTY83-110, KTY83-120, KTY83-121, KTY83-122, KTY83-150, KTY83-151, KTY83-152
- KTY84-130, KTY84-150, KTY84-151
The Alpha Therm PTC series is a reliable and cost-effective solution for temperature measurement and control in a wide variety of applications including drives, motors, spindles, inverters, control systems, instruments, equipment, compressors and process control.
