TSK -Corrugated Ribbon Wound Silicone-Coated Resistors
TSKR - Adjustable

Series TSK: corrugated alloy tape wound edgewise and held onto a tubular ceramic support by silicone cemented at a very high temperature. Ribbed construction, both sides of the tape on direct contact with cooling air, thus providing a covection area four times greater than that obtained with conventional wirewound resistors.

They are capable to withstand heavy overload surges -up to seven times their rated wattage at 420ºC during twenty seconds- and most suited for controlling motors and equipment requiring high wattage dissipation, low resistance values and high current capacity.

Adjustable type, TSKR, may be fitted with intermediate lugs round the winding space, thus permitting to select whatever ohmic values wanted within the total resistance.
 
Series TSK, TSKR  agree with CCTU 04-02C requirements.
