14D271K MOV Varistor 270V

14D271K MOV varistor (270V), also known as VDR-14D271K, is designed for DC and industrial systems operating at higher voltage levels where strong surge protection is required.

Compared with 14D241K, this model offers increased voltage tolerance, making it suitable for applications around 240V–270V DC systems with improved stability under transient conditions.

Typical Use Case:

This model is widely used in industrial power supplies, automation systems, communication equipment and embedded electronics to protect against switching surges, ESD and transient voltage spikes.

The 14mm disc design ensures robust surge capability and stable performance under repetitive stress conditions.

Key Electrical Characteristics:

Varistor Voltage (1mA): 270V ±10%  

Maximum Continuous Voltage: 175VAC / 225VDC  

Maximum Clamping Voltage: approx. 455V  

Peak Surge Current (8/20μs): 4.5kA  

Maximum Energy (2ms): 200J  

Capacitance (1kHz): approx. 850pF  

Application Focus:

DC power systems (240V–270V)  

Industrial automation equipment
