CVD Diamond Hight Power  Resistor
 

CVD Diamond for Hight Power   Resistor applications
 

 

 

These resistors provide extremely high power rating possibilities on smallest area and can be used in applications up to 30 GHz.

The devices are suitable for applications requiring high CW and peak powers, a broad

frequency response and small dimensions.

All thin film product with pure Au contacts, suitable for soldering and wire bonding.
