Non-inductive resistor, 50Ω (1%), 30W

This is an high precision non-inductive thick film resistor suitable for RF terminations till 30W continuous power. For a correct mounting it needs an adequate heat sink. This resistor has both pins insulated from ground so any pin can be used for ground connection or for RF line. If it is used at high frequencies (> 300 MHz) it is recommended to leave about 6 mm of empty space between the pins and their connection, as you can see in the picture below. For a better cooling of the resistor it is preferable to mount it about in the center of the heat sink. It is provided without the heat sink.
