The 20DKJ series varistors are packaged in 20mm discs, providing circuits with a wide range of overvoltage protection from 18V to 1800V. As one of the enhanced transient voltage suppression solutions, it can quickly conduct when facing strong transient high voltages, effectively absorbing and clamping surge energy due to the unique nonlinear characteristics of zinc oxide particles.
This device has higher surge current tolerance and excellent energy absorption characteristics, and can reliably cope with severe lightning strikes and switching transient shocks.
It is an ideal choice for industrial control systems, large power supply equipment, communication base stations, and various electronic products with extremely high requirements for protection performance, ensuring the long-term stability and safe operation of sensitive components in harsh electrical environments.
