FEATURES
■ High resistance resistors for high voltage circuits.
■ Thin SIP shape.
■ The flame retardant coats corresponding to UL94V-0 are used.
■ Thick film resistors (RuO2) ensure high stabilities in life and change in aging.
■ Products with lead free termination meet EU-RoHS requirements. EU-RoHS regulation is not intended for Pbglass contained in electrode, resistor element and glass.
DERATING CURVE
For resistors operated at an ambient temperature of 70ºC or above, a power rating shall be derated in accordance with the above derating curve.
