Varistors, also known as metal oxide varistors (MOVs), are comprised of two electrodes separated by a ceramic or semiconductor material. A varistor has a non-linear response, meaning every volt has a different current. When applied, each varistor is able to filter out any transient voltages that exceed their given upper and lower working parameters.

The 82550040 varistor is a metal oxide varistor (MOV) from Alkon Corporation that’s designed for over voltage protection for telecom applications, such as EMC systems, local exchange equipment, and outdoor enclosures. This particular device is a NTC thermistor with a high-surge absorbing capacity and an excellent clamping & leakage performance. The 82550040 is available in four different configurations, including a generic through-hole version (125-30) and two specialized versions (125-35 and 75-30).

The typical working principle of MOVs is to effectively reduce the risk of over-voltage in telecom applications. These devices act as a voltage clamp and have the capacity to absorb short-term voltage surges, dissipating the energy so that the protected system is not damaged. This varistor from alkon Corporation is designed with a high thermal and electrical stability, and is able to ensure that the equipment is reliable and durable.

The 82550040 is well-suited for use in medium-voltage systems and can handle the higher levels of current required by large telecom applications. It has a superior protection range of -35V to +125V and a clamping voltage of 20V. This varistor also boasts a high energy dissipation capacity of up to 30 joules while still offering excellent surge protection and a low capacitance.

The 82550040 metal oxide varistor is a great choice for applications in telecoms, as its high performance and performance stability provide reliable protection against over-voltages. It offers superior clamping and leakage protection while keeping capacitance low, making it a strong choice for medium voltage applications. By protecting the system from transient voltages, this device helps to ensure maximum up-time and long-term equipment reliability in telecom systems.
