Preferred application
For reducing the rate of rise
•
For RF attenuation
•
The values have been selected such that effective interference
suppression can be achieved across a broad spectrum.
The varistor circuit can absorb a high level of energy and can be used
for frequencies ranging from 10 to 400 Hz (controlled operating
mechanisms). There is no limiting below the knee-point voltage.
