Selecting Bourns IsoMOV Components for Protection

This white paper provides guidance on selecting the appropriate Bourns® IsoMOV™ hybrid protector for various applications. It outlines key considerations that developers should evaluate, including surge protection needs, voltage levels, energy handling capacity, and environmental conditions. The paper details the unique construction of IsoMOV™ protectors, which combine Metal Oxide Varistor (MOV) and Gas Discharge Tube (GDT) technologies to enhance reliability and performance. It describes the steps to understand a system's voltage type, assess surge requirements, evaluate energy absorption capability, and consider clamping and let-through voltages. Additionally, the paper emphasizes the importance of environmental factors, such as temperature and humidity, in ensuring the long-term reliability of the chosen model. By following these guidelines, developers can select the right IsoMOV™ model that effectively safeguards their specific system designs against electrical threats.
