Offering resistance values up to 10TΩ, Ohmite’s Ultramox series supports their popular Slim Mox resistor family and allows for tighter tolerances than previously available, down to 0.25%, and TCR’s as low as 25ppm. Offered in four standard sizes, the series is rated from 10 to 30kV and from 1 to 3W.
Using thick film technology, the radial lead resistors can be made to suit customer specific applications and the silicon coating provides climatic protection to EN 60068-1: 55/125/56. The Ultramox resistors operate over a temperature range from -55 to +125°C.
Other wire diameters and thicknesses are available and Ohmite can produce axial versions, or, if preferred, resistors with formed leads or lead frames.
