The low profile design of the FRW series resistor makes it extremely flexible in that its mounting can be in a horizontal or vertical axis and several resistors can be ‘stacked’ by means of spacers, meaning a high level of heat dissipation is possible within a limited space. The FRW is available in the following ratings: 20 Watt, 30 Watt, 50 Watt, 65 Watt and 75 Watt.
