4 / 5 page UL Recognised Wirewound Resistors ULW Series Fusing Performance ULW5 Fusing Characteristic 0 10 20 30 40 50 60 80 100 120 140 160 180 200 Initial Power (W) Notes: 1. Typical fusing times are around 1/3 of the maximum figures. 2. After fusing the resistance value is >100 times the initial nominal value, provided the initial power is at least 20 x rated power. 3. Suitable for fusing at voltages up to 264Vrms. Application Notes Application Notes 1. If the resistors are to dissipate full rated power, it is recommended that the terminations should not be soldered closer than 4mm from the body. 2. Due to operating temperature limits imposed by some PCB materials, derating may be necessary. An estimate of the temperature rise to be expected can be calculated using the thermal impedance figures given under Electrical Data. 3. For the purposes of UL approval, the following points should be observed: 3.1 To protect against fire under all conditions of overload, a positive clearance of at least 13mm should be provided between the body of the resistor and any combustible materials. 3.2 A positive clearance of 13mm should be provided between the resistor body or terminations and uninsulated parts of opposite polarity or uninsulated dead metal parts. 3.3 Limited Short Circuit testing should be performed in the complete appliance. www.bitechnologies.com www.irctt.com www.welwyn-tt.com General Note TT electronics reserves the right to make changes in product specification without notice or liability.
