Thick-film resistor UVR series

power

Ⅰ Ultra low profile thick-film on steel Ⅱ 500W to 7kW peak power Ⅲ Single fixing heatsink mountable Ⅳ Ideal for dynamic braking, inrush limit and snubber circuits Ⅴ Choice of flying lead, push-on or solder terminations Ⅵ Low inductance design Ⅶ High isolation, even after failsafe overload fusing Ⅷ RoHS compliant, non-flammable construction Applications： A heatsink with thermal resistance ≤0.53℃/W will enable the component to operate at its continuous power rating. Thermal grease (e.g. DowCorning DC340) should be used and the heatsink should have a surface finish of<6.3μm with flatness of<0.05mm. The resistor should be mounted using a screw head bolt of size M5 forUVR2, 3, 5 & 7,M3 forUVR1 and M2 forUVR1/2. This should be torqued to 2.5Nm ±10%. UVR resistors will fail safe (open circuit) under overload fault conditions and still maintain a 1kV dielectric withstand.
