The MOF1WS-220K is a series of surface mount resistors produced by the SR Passives company. It is composed of a flame-retardant epoxy coating and nickel barrier layer, which ensures mechanical and environmental protection. This resistor also has a nickel-chrome power element, which allows it to handle higher operating temperature and power levels. The resistor has a tolerance of ± 1%, a 2W power rating, and is available in a range of resistance values from 220 ohms up to 220K ohms. This component is widely used in applications such as automotive, consumer electronics, telecommunications and industrial equipment.
