HIGH POWER CHIP RESISTORS & TERMINATIONS GENERAL INFORMATION: When mounted on an appropriate heat sink, these chip devices provide high power dissipation in terminations and as balancing resistors in Wilken- son power divider networks. Laser trimming provides maximum peak and average R.F. power capability.
