AMETHERM SL1210005 Datasheet & Stock

The SL12 10005 is a radial leaded NTC thermistor designed for inrush current limiting applications. It helps protect components in switching power supplies and other power devices by initially presenting a high resistance that limits current when equipment is turned on. As it heats up, its resistance drops to a negligible level, allowing normal operation. This thermistor is typically placed in series with diodes, motors, or other components requiring inrush protection. It can be used in series with surge limiters for enhanced protection. Specifications include a maximum steady-state current of 5A at 25°C, a maximum recommended energy of 60J, and an actual energy failure at 120J. It features a dissipation constant of 12.7mW/°C, a thermal time constant of 47 seconds, and an initial resistance of 0.13Ω at maximum current. Made from C-type material, it is suitable for motor drive and control, power management, audio, industrial, and safety applications.
