RTOP
Power Resistor for Mounting onto a Heatsink
Thick Film Technology
Vishay Sfernice
POWER RATING CHART
The temperature of the heater should be maintained in the limit specified. To improve the thermal conductivity, surfaces in
contact should be laid on with a silicon grease and the torque applied on the screw for tightening should be around 2 Nm.
MARKING
Series, style, ohmic value (in), tolerance (in %), manufacturing date, VISHAY trade mark.
