14D270K MOV Varistor 27V

14D270K MOV varistor (27V), also known as VDR-14D270K, is a low to medium voltage metal oxide varistor designed for transient suppression in control circuits and DC power systems.

Compared with lower voltage MOVs such as 14D180K and 14D220K, this model provides a higher voltage margin, making it suitable for circuits with slightly higher operating voltage while maintaining fast response to transient spikes.

Typical Use Case:

14D270K is commonly used in DC power systems, signal interfaces, industrial control boards and embedded electronics to protect against electrostatic discharge (ESD), switching transients and voltage spikes.

The 14mm disc structure ensures a good balance between energy handling capability and response speed, making it suitable for both sensitive and industrial electronic environments.
