Tab & Cover Resistors

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.

Suggested mounting procedures:

1.Solder part or tabs in place with controlled temperature iron (260℃)

2.Forming a small loop in the tab will act as a strain relief as the heat is dissipated.
