S20K50 VARISTOR 82V 6.5KA DISC 20MM

The S20K50 is a robust and reliable varistor, also known as a Voltage Dependent Resistor (VDR), designed to protect electronic circuits from voltage surges and transient events. This disc-shaped varistor, with a diameter of 20mm, is engineered to clamp voltage spikes and divert excess current away from sensitive components, safeguarding them from damage. The S20K50 is characterized by its clamping voltage of 82V and its surge current capability of 6.5kA, making it suitable for a wide range of applications where voltage protection is critical. Varistors are essential components in power supplies, surge protectors, and other electronic devices that are susceptible to voltage transients caused by lightning strikes, inductive load switching, and electrostatic discharge (ESD). The S20K50 operates by exhibiting a high resistance at normal operating voltages and a low resistance when the voltage exceeds its clamping voltage. This allows the varistor to effectively shunt excess current away from the protected circuit, preventing damage to sensitive components.

The 20mm disc size provides a balance between surge handling capability and physical size, making it suitable for a variety of applications. The S20K50 is commonly used in AC power line protection, DC power supply protection, and transient voltage suppression in automotive electronics. Its high surge current capability and fast response time make it an effective solution for protecting against a wide range of voltage transients. When selecting a varistor, it is important to consider its clamping voltage, surge current capability, and energy handling capability. The clamping voltage should be slightly higher than the normal operating voltage of the protected circuit, and the surge current capability should be sufficient to handle the expected transient currents. The S20K50 is designed to meet industry standards for voltage surge protection, ensuring reliable performance and long-term stability.

Its robust construction and high-quality materials make it a durable and dependable component for any electronic circuit. The S20K50 is a versatile and reliable varistor that can be used in a wide range of voltage surge protection applications. Whether you're designing a power supply, a surge protector, or an automotive electronic system, the S20K50 provides a high-performance and cost-effective solution. Its high surge current capability, fast response time, and robust construction make it a valuable component for any electronics engineer.
