Ametherm Standard, Mega, Mini and Sensor Sample Kits

Sample kits of Ametherm’s inrush current limiters and NTC sensing thermistors are now available. The kits make it quick and easy for designers to find the right part to provide circuit protection, temperature compensation and measurement in their applications.

The Standard Sample Kit consists of nine 120 and 240 VAC inrush current limiters from the SL series. The devices feature resistance values at 25°C of 10Ω, diameters from 3–32 mm and steady-state current from 1–15 A. For single- and three-phase input voltages up to 680 VAC, the Mega Sample Kit features five inrush current limiters from the MegaSurge series. The devices offer diameters from 14–37 mm, up to 500 J of input energy, steady-state current to 18 A and resistance values at 25°C of 10Ω, 30Ω and 150Ω.

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 metal oxide ceramic materials, the devices feature resistance values at 25°C from 10–100 kΩ, beta of 3950 and 4500 K, thermal time constant down to 10 s and maximum power of 125 mW. The kit also includes a device from the ACCU-Curve series of interchangeable thermistors. Offering tight tolerance of ±0.2°C and a fast thermal time constant of 7 s, the epoxy-coated device can be potted in a variety of housings.

The devices are optimised for a wide range of applications, including AC motors, power supplies, motor drives, audio amplifiers, battery chargers, air sensors, HVAC systems, high-speed computers, MRIs and X-ray machines.
