PDF File

These are 5mm X 2mm and 7mm X 2mm, 10W power chip resistors for RF applications.  TFH and TFK are lead free.
The TFJ has two beam leads.  The Strong terminals of the TFH are designed to extract heat from the resistor chip to the circuit
board. The TFJ and TFK have metal backs for superior heat extraction. The 10W (TFH72, TFH52) and 20W (TFK52, TFK72)
power ratings are available with beryllium free design. 1% tolerance and 50ppm/C ensure stable circuits. Applications include:
RF power amplifiers, RF power sources, fixed stations for cell phones, RF measurement and terminations of circulators/ isolators.
