Ceramic resistors from Ohmite are used as dump resistors and for inrush current-limiting due to the high energy absorption capability. This is the most cost effective and compact resistor technology for these types of application.

Resistors can be combined to meet any voltage, average power and peak energy specification that you may require. Talk to one of technical sales team using the chat window, email sales@ppm.co.uk or call us on +44 (0)1793 784389.
