Product Description
Product Overview
Precision Metal Film Fixed Resistors manufactured by UNI-ROYAL, featuring flame retardant type availability, low noise, low voltage coefficient, and a low temperature coefficient range. These resistors offer superior moisture protection due to multiple epoxy coatings on vacuum-deposited metal film and stable performance in various environments thanks to a nichrome resistive element. They are compliant with RoHS directive and meet halogen-free requirements.
