TYPICAL APPLICATIONS
RESISTANCE TOLERANCE : + 10% [K] - [STD]; + 5% [J] - on request
In RSR Series, a corrugated alloy tape is wound edgewise or flat onto a ceramic tube which is coated with a
silicone resin.
This ribbed construction puts both sides of the resistive element in contact with air thus creating a convection
area four times greater than that obtained with normal wire wound resistors.
These resistors are designed primarily to withstand heavy overload surges upto max 7 times their rated
wattage for 10 to 15 seconds (max). This characteristic makes them most suitable for controlling motors
requiring high dissipation, low resistance values and high current capacity.
