NTC inrush current limiting thermistors handle steady-state currents
Available in multiple leaded package options with diameters from 7.6 to 31.75mm, the components offer resistance at 25°C (R25) from 0.4 to 220Ω with tolerances down to ±10%, maximum operating voltage to 265V RMS, and beta from 3000 to 3965°K. Constructed of specially formulated metal oxide ceramic materials, RoHS-2- and REACH-compliant the thermistors are optimised for applications that require inrush current limiting to reduce noise and circuit failure, including switching power supplies, AC motors, motor drives, audio amplifiers, and battery chargers. According to the company. in these applications the thermistors can lower rectifier costs by reducing the required peak forward-surge-current rating. The Amertherm thermistors are available from the distributor Digi-Key.
