With its industry-high voltage rating, Ametherm’s MCL20 500100-A can withstand hundreds of hits of maximum inrush current without degrading.
The device offers a short reset time, and as a PTC thermistor a quick reset will not result in a large inrush current, as its resistance is already at a high state. The result is extremely high reliability and stability in high-voltage applications.
With a 19 mm diameter, 9 mm maximum profile, and 7.8 mm lead spacing, the MCL20 500100-A provides designers with a more compact and cost-effective alternative to combining a power resistor, relay, and timer on one circuit to achieve the same functionality.
Offered direct or through Ametherm’s network of distributors, samples and production quantities of the MCL20 500100-A are available now.
Target Applications:
Inrush current limiting and overcurrent protection in applications such as welding equipment and plasma cutters with extremely high voltages from 480 V to 930 V
