The OF470JE OF Series are small, reliable carbon composition resistors with exceptional strength. They are made tough by a molding process that combines the terminals, insulation and resistive element into an integrated unit. Along with their small size, the OF Series perform with low noise, dissipate heat rapidly and offer high temperature stability. Color codes are readable after prolonged use thanks to a very durable coating that resists abrasions and chipping normally associated with automatic insertion equipment.
