BOURNS ZV20K1812801NIR1HT

The ZVHT series of low voltage multilayered varistors is designed to protect sensitive electronic devices against high voltage surges in the low voltage region. They offer excellent transient energy absorption due to improved energy volume distribution and power dissipation. Low voltage varistors cover a wide DC operating voltage range from 3 V to 170 V. In addition, the ZVHT series exhibits independent suppression characteristics enabling stable protection over a wide temperature range of -55 to +150 °C. ZVHT series varistors are typically applied to protect integrated circuits and other components at the circuit board level.
