Digi-Key offers Ametherm sample kits

Sample kits of Ametherm in-rush current limiters and NTC sensing thermistors are now available from Digi-Key.

The component distributor stocks Standard, Mega, Mini, and Sensor sample kits. They can be used to test a range of devices, making it quick and easy to find the right part to provide reliable circuit protection and high-accuracy temperature compensation and measurement in applications.

The Standard sample kit consists of nine 120 and 240V AC inrush current limiters from the company’s SL series. The devices feature resistance values at 25 degree C of 10Ohm, diameters from 3.0 to 32mm, and steady-state current from 1.0 to 15A.

For single- and three-phase input voltages up to 680V AC, the Mega sample kit features five in-rush current limiters from the manufacturer’s MegaSurge series. The devices offer diameters from 14 to 37mm, up to 500J of input energy, steady-state current to 18A, and resistance values at 25 degree C of 10, 30, and 150Ohm.

The Sensor sample kit of NTC sensing thermistors includes four probe assembly types, ring lug, threaded hex nut and tip, epoxy, and steel housing. Constructed of specially formulated metal oxide ceramic temperature sensing materials, the devices feature resistance values at 25 degree C from 10 to 100kOhm, beta of 3,950 and 4,500K, thermal time constant down to 10 sec, and maximum power of 125mW. The kit also includes a device from the company’s Accu-Curve series of interchangeable thermistors. Offering tight tolerance of ±0.2 degree C and a fast thermal time constant of 7.0sec, the epoxy-coated device can be potted in a variety of housings.
