UVR Ultra Low Profile Power Resistors

㈠Features：

 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

㈡Applications：

 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.
