Abstract:
Voltage Dependent Resistor 1, which are made of silicon carbide show a high degree of non-linearity between their resistance value and the applied voltage. The voltage dependency is caused by the contact resistance between the carbide crystals. The electrical characteristic of the pressed conglomeration is determined by a large number of crystal contacts which form a complicated network of series and parallel resistors. Simple stabilization circuits may be realized with the help of these resisotrs and they have found a diversity of applications in television and industrial circuits. Used as spark suppressors they offer a cheap and reliable solution for protection of rely contacts.
