1 Watt Metal Oxide Resistors

Metal Oxide resistors are designed for demanding applications where long-term stability under high-temperature conditions is required. Built around a high-purity ceramic core with an excellent flame-retardant coating, these 1W resistors deliver quiet, stable performance across diverse operating environments. Please note that with resistor values, a k or M represents a dot. Eg 5k6 is equivalent to 5.6k or 3m3 is equivalent to 3.3M. If you need help with colours and values, use our Resistor Colour Code Calculator here.
