resistors RCR anti-surge power type leaded resistor EU features • Excellent anti-surge characteristics • Stable characteristics of moisture resistance up to high resistance range. • RCR50 +(1MΩ - 12MΩ), RCR50EN (1MΩ - 12MΩ) and RCR60 (1MΩ - 12MΩ) are discharge resistors recognized by UL1676 and c-UL(CSA-C22.2 No.1-M94). • RCR50EN (100kΩ - 33MΩ) and RCR60 (470kΩ - 56MΩ) is approved by EN60065 14.1 safety. There is the case that RCR50EN cannot meet CLASS II depending on a use. • Marking: Blue-gray body color with color-coded bands • Products with lead-free terminations meet EU RoHS requirements. EU RoHS regulation is not intended for Pb-glass contained in electrode, resistor element and glass. • Surface mount style “N” forming is suitable for automatic mounting dimensions and construction Type L t Trimming Line l Ceramic Core t d D Dimensions inches (mm) D d (nom.)
