Positive Temperature Coefficient (PTC) Characteristics N/A PTC Thermistors have self-regulating characteristics and will not overheat. If a current runs through each thermistor, it will auto-stabilize at a certain temperature. This results in safer operation, better conductivity, greater operating efficiency, a stable electronics response, and longer life expectancy.
Innovative Features N/A
  • Safe
  • Energy efficient
  • Low cost operation
  • No electrical noise
  • No thermostat required
  • No moving or wearable parts
  • Very long operating life
Custom Designs N/A Standard PTC Thermistors are supplied in round, square, or rectangular shapes. Additional sizes and configurations can be customized depending on application requirements and order quantities.

PTC Thermistors can be used in a variety of applications, including:
  • Heating Plates
  • Drying Machines
  • Hair Dryers
  • Hot Melt Glue Guns
  • Foot Warmers
  • Diesel/fuel Heaters
  • Self-regulating Heating Elements
  • Carburetor Pre Heating
  • Irons
PTC Thermistors are an effective means of safe and energy efficient heating and are ideal for applications where space is limited and where low power consumption and long life operation are desired.
Note N/A For low volume round PTC thermistors with unique dimensions, please also consider using square type PTC thermistors with a slightly higher temperature for faster delivery and lower minimum order quantities.

Example
  • A round PTC thermistors of 8.5 mm can be replaced with square PTC thermistors with 6.0 x 6.0 mm (8.5 x 0.707 = 6.01 mm).
  • A round PTC thermistors of 12.5 mm can be replaced with square PTC thermistors with 8.5 x 8.5 mm (12.5 x 0.707 = 8.84 mm).
  • A round PTC thermistors of 15.6 mm can be replaced with square PTC thermistors with 11.0 x 11.0 mm (15.6 x 0.707 = 11.03 mm) using decimal places of 0.5 mm.
  • Please contact us for current inventory stock status before placing orders.
  • Voltage, dimensions, resistance, temperature, or Curie temperature can also be customized for large quantities (longer lead times and large minimum order quantities may apply).
  • For lower temperature applications (10 ºC ~ 90 ºC), please consider our LCHT range of PTC Heat Conductor products with the characteristics of no inrush current, stable power, and adherence to Ohms Law. Ratings: 3V AC/DC ~ 600V AC/DC (CUL, CE), T ºC =10 ºC ~250.
  • PTC Thermistors contain Pb under the permission of RoHS exemption 7(c)-I: Electrical and electronic components containing lead in a glass or ceramic other than dielectric ceramic in capacitors, e.g. piezoelectronic devices, or in a glass or ceramic matrix compound.
