14D180K MOV Varistor 18V

14D180K MOV varistor (18V), also known as VDR-14D180K, is a low voltage metal oxide varistor designed for fast transient suppression in signal lines and sensitive electronic circuits.

Unlike higher voltage MOVs used in power systems, 14D180K is optimized for low voltage applications where quick response and precise clamping are critical to protect integrated circuits and communication interfaces.

Typical Use Case:

14D180K is commonly used in DC power circuits, signal lines, control boards and communication electronics to protect against electrostatic discharge (ESD), switching spikes and transient overvoltage events.

Its 14mm disc structure provides a balance between response speed and energy absorption capability, making it suitable for applications where both sensitivity and reliability are required.

Key Electrical Characteristics:

Varistor Voltage (1mA): 18V ±10%

Maximum Continuous Voltage: 11VAC / 14VDC

Maximum Clamping Voltage: approx. 36V
