features
• Manufactured to type RK73 standards
• Less board space than individual chips
• Four or eight bussed resistor elements included
in one array, concave terminations
• 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.
