VISHAY AMETHERM NTC Thermistor, 10 Ohm, 6A, 15mm Disc

The VISHAY AMETHERM SL15 Series NTC Thermistor is a high-performance radial leaded component designed to protect sensitive electronics from damaging inrush currents. Acting as an inrush current limiter, it provides an initial high resistance when equipment is first powered on, which quickly drops to a negligible level as it heats up from the current flow. This intelligent behaviour safeguards switching power supplies and other power devices, preventing component stress and failure during startup.

With a robust construction featuring a 15mm disc, this thermistor is rated for use in circuits up to 480V AC. It offers reliable performance with a maximum steady-state current of 6A at 25°C and can handle a maximum energy rating of 55J under the same conditions. Its thermal characteristics include a 54-second time constant and a dissipation constant of 15.9mW/°C, ensuring stable and predictable operation in demanding environments.

Key Applications

This component is essential for managing the initial power surge in various electronic systems. Its primary function is to provide a soft start, extending the lifespan of capacitors, rectifiers, and other vulnerable parts within the power circuit.
