The "U" series of non-inductive, ceramic composite resistors are designed for inrush limiting in motor drives, UPS and other power conversion systems. They are ideal for circuitry which is subject to surges, high peak power or high energy, offering enhanced performance over other resistor types. In pulsed applications, these compact resistors distribute the energy uniformly throughout their structure, resulting in low thermal stress. The result is increased reliability, and reduced size, compared to other resistor types. High-temperature, solvent-resistant epoxy coating allows operation in almost any environment, and the familiar radial lead construction offers convenient use.
