Vishay Ametherm SL15 NTC Thermistor 10 Ohm 6A 15mm Disc

Vishay Ametherm SL15 NTC Thermistor 10 Ohm 6A 15mm Disc is a radial leaded NTC thermistor with a resistance of 10 Ohm at 25°C and a maximum steady-state current of 6A. It is designed as an inrush current limiter to help protect sensitive electronics from damaging inrush currents at power-on.

Overview

The SL15 Series thermistor presents a high initial resistance when equipment is first powered on. As current flows, the component heats up and its resistance drops to a negligible level. This behaviour helps safeguard switching power supplies and other power devices by reducing component stress and failure during startup.

With a 15 mm disc, this thermistor is rated for use in circuits up to 480V AC. At 25°C it can handle a maximum energy rating of 55J. Its thermal characteristics include a 54-second thermal time constant and a dissipation constant of 15.9 mW/°C.

Applications

This component is used to manage the initial power surge in electronic systems, providing a soft start. This can help extend the lifespan of capacitors, rectifiers, and other vulnerable parts within the power circuit.
