Tab & Cover Resistors

Florida RF Labs Tab & Cover resistors are ideal for mounting directly

to a heat sink or onto a circuit board. The resistors are available with BeO, Aluminum Nitride (AlN) or Alumina substrates. These devices have standard resistance values of 50 & 100 ohms, however, are available in many non-standard values as well. The power rating ranges from 10 to 500 watts. Applications include Wilkinson divider/combiner that require low capacitance to ground. Packaging options are tray or tape & reel. All devices are available RoHS compliant.
