3SM222KMB1HA-P

Overview

The 3SM222KMB1HA-P is a high-voltage metal oxide varistor (MOV) manufactured by Solid State System. This component features a disc-shaped ceramic body designed for surge protection applications in electrical circuits. It is characterized by its ability to clamp transient voltage spikes and divert excess current away from sensitive downstream components. The device utilizes zinc oxide grains within a binder matrix to achieve non-linear voltage-current characteristics, ensuring stable performance under repeated surge events while maintaining low leakage current during normal operation.

Feature Summary

• Provides robust clamping of high-energy voltage transients
• Utilizes zinc oxide technology for reliable non-linear response
• Designed for long-term stability in harsh electrical environments

Applications

• Industrial power supply input protection
• Motor drive circuit surge suppression
• Transformer primary side overvoltage protection

Procurement Notes
