Metal Oxide Varistor DISC 20mm ZOV-20D470K
The Zinc Oxide Varistor DISC 20mm ZOV-20D470K is a high-reliability voltage-dependent resistor designed for protecting low-voltage electronic circuits against transient overvoltage events such as switching surges, inductive spikes, and electrostatic discharge. Built using zinc oxide (ZnO) ceramic technology, this varistor provides highly nonlinear voltage-current characteristics, enabling rapid response and effective energy absorption.
Features:
- Nominal varistor voltage of 47V with ±10% tolerance.
- High surge current capability up to 6.5kA (8/20µs).
- High energy absorption capability for transient suppression.
- Fast response time for effective overvoltage protection.
- Low leakage current and high insulation resistance.
- Radial leaded through-hole mounting.
- 20mm disc size for enhanced power handling.
- Wide operating temperature range from -40°C to +85°C.
