14D112K MOV Varistor 1100V

14D112K MOV varistor (1100V), also known as VDR-14D112K, is designed for AC power lines and high voltage industrial systems where high energy surge protection is required.

This model is typically applied in AC mains circuits and environments exposed to lightning surges, switching spikes and unstable grid conditions.

Typical Use Case:

14D112K is widely used in industrial equipment, power supplies, electrical control systems, household appliances and surge protection devices (SPD) to protect circuits from high energy transient overvoltage.

The 14mm disc structure provides strong energy absorption capability and ensures reliable performance under repetitive surge stress.

Maximum Continuous Voltage: 680VAC / 895VDC  

Maximum Clamping Voltage: approx. 1815V  

Peak Surge Current (8/20μs): 4.5kA  

Maximum Energy (2ms): 340J  

Capacitance (1kHz): approx. 180pF  

Application Focus:

AC power systems  

Industrial equipment  

Power distribution systems  

Household appliances  

Surge protection devices (SPD)  

Design Tips:

* Select MOV voltage according to AC mains voltage level  

* Install across line-to-line or line-to-ground positions  

* Combine with GDT or TVS diodes for multi-stage surge protection  

Engineering Insight:

14D112K is typically selected for very high voltage AC systems where strong surge absorption is required. It plays a key role in protecting circuits against lightning-induced surges and unstable grid conditions.

Comparison Insight:

Comparable to TDK EPCOS S14K680, this model can be used as an alternative solution for high voltage AC protection applications.
