Voltage Dependent Resistor is nonlinear two-element semiconductors that drop in resistance as voltage increases. Voltage dependent resistors are often used as surge suppressors for sensitive circuit.
Voltage Dependent Resistor can be radial in disc with size 5mm,7mm,10mm,14mm,20mm,25mm,32mm,34mm,40mm,53mm,60mm and leadless package in 0603, 0805, 1206 and 1210 sizes.
The nonlinear characteristic of Voltage Dependent Resistor is ideal as surge protector devices,can be lightning strikes, electrostatic discharges or inductive discharge from motors or transformers.
Disc varistor with wide voltage range 18-1800V and completed approvals CQC UL CSA VDE.The following is about Radial Leaded Voltage Dependent Resistor related, I hope to help you better understand Radial Leaded Voltage Dependent Resistor.
