Description
CL20-101130 Ametherm PTC Thermistor 100 Ohms 0.650A-1.750A 1200VDC 600J 100.0W Radial Disc 22 mm
The CL20 Series of PTC thermistors provides stability and reliability in high-voltage applications, and can withstand hundreds of hits of maximum inrush current without degrading. PTC thermistors do not require reset time and therefore will not result in large inrush current during repetitive use, as their resistance remains in a high state.
Devices in the CL20 Series of PTC thermistors feature a dissipation constant of 22.5 mW/°C, heat capacity from 2.0 J/°C to 3.45J/°C, transition temperature of +120 °C and a thermal time constant of 65 s. Switch and continuous currents for these PTC thermistors range from 450 mA to 1750 mA and 225 mA to 850 mA respectively.
The radial-leaded CL20 Series offers easy PCB mounting, have a diameter of 22 mm, straight leads, and most come with optional outside or inside kinked leads. Ametherm also offers smaller PTC circuit protection devices with diameters from 6 mm to 20 mm.
