ABSTRACT:
A free-standing, thick-film varistor is fabricated by screen printing on a smooth aluminum oxide substrate an unfired standard varistor powder mixed with a suitable organic carrier and heating the printed varistor at high temperature (1000.degree. C.-1400.degree. C.). The fabricated varistor adheres lightly to the insulating substrate and may be easily separated therefrom. The insulating substrate may be reused.
