DIMENSIONS: MM (INCHES) Electrical Characteristics Characteristic FW Series Power 1, 2, 3, 5, 7** W Resistance Range 4.7 ohms to 100 ohms (E24 values) UL Listed Resistance Range 4.7 ohms to 47 ohms Tolerance 5 % Temperature Coefficient ±200 PPM/°C Operating Temperature Range -55 °C to +155 °C Maximum Voltage √P*R Fusing Point See Fusing Performance Chart Fusing Time See Fusing Performance Chart Product Dimensions General Introduction The FWxxA Series of axial leaded wirewound resistors is designed to fuse under abnormal conditions such as sudden surges in voltage or circuit malfunctions. The resistor will fuse upon application of 120 or 240 voltages. The resistor will fuse safely if 120 or 240 V is applied. The time to fuse depends on the resistance value. ** 7 W = 240 Vac only.
