POWER RESISTOR
Type RX20
Fixed or Adjustable
FEATURES:
Vitreous Enamel Coating 5% & 10% Tolerance
All Welded Construction Flame Resistance
SPECIFICATIONS:
OVERLOAD: 10 times rated wattage for 5 seconds
TEMPERATURE COEFFICIENT: ± 260PPM/° C
DIELECTRIC WITHSTANDING STRENGTH: 1000 VAC on all wattages
Note: For adjustable resistors 100% of the resistance must be in the circuit for 100% of rated wattage.  By setting the adjustment at a lesser resisitance the wattage will drop proportionatley. Example: a 12 ohm resistor set at 4 ohms would be at 1/3 of original wattage.
