Varistors Dimensions
The 40D series Varistors typically have a disc diameter of 40mm, making them suitable for various industrial applications where robust surge protection is required.
Selection of Zinc Oxide Varistor
When selecting a zinc oxide varistor, consider the maximum allowable voltage, varistor voltage, clamping voltage, and energy absorption capabilities to match the specific protection requirements of your application.
Working Principle of High Voltage Varistor
High voltage varistor operates by maintaining a high impedance at normal voltages. When a surge occurs, the impedance drops, allowing the Varistors to conduct current and shunt excess voltage away from sensitive components, thereby protecting the circuit from damage.
Varistors Naming Rules
Varistors are categorized based on their voltage ratings, energy handling capacity, and application type. The naming convention typically includes series identifiers and specific characteristics like maximum allowable voltage and varistor voltage.
