.TVS (transient voltage suppressor) diodes and Varistors (variable resistor) are two important components used in the circuit to suppress any surge or high voltage of transient type. Varistors can be used to eliminate overvoltage problems and suppress any associated surge current that may occur during any electrical fault. The MOV (metal oxide varistor) is a passive, voltage dependent resistor which can absorb voltage spikes in a circuit and shut them down to a safe level.
The B72225S4301K101 series is a metal oxide varistor (MOV) used by engineers and technicians to prevent voltage transients in a circuit. It delivers a highly robust performance, with excellent resistance to transients and surges. The B72225S4301K101 is designed to provide the highest level of performance, with its low voltage leakage current and its wide operating voltage range across all temperatures. In addition, due to its high capacitance value and extremely low resistance, it allows for excellent equipment protection and will effectively handle large transient events.
The B72225S4301K101 is typically used in low-voltage applications like consumer electronics, control circuits, power supplies, audio equipment, and low-voltage motors. It is also used for AC power line protection, automotive electronics, and telecommunications systems. The B72225S4301K101 is suitable for all industrial and commercial applications, including those in harsh environmental conditions.
The working principle behind the B72225S4301K101 is that of electrical conduction. When a surge occurs in a protected circuit, the B72225S4301K101 will absorb the energy of the surge and quickly reduce it to a safe level. This energy is conducted through the material of the varistor, creating a path of least resistance for the transient over-voltage away from sensitive equipment. As the material of the varistor conducts the surge, the resistance of the material increases, allowing for a much higher peak current to be conducted away from the protected area.
The unique characteristics of the B72225S4301K101 make it ideal for use in any application requiring energy suppression or transient over-voltage protection. Its low voltage leakage current and high capacitance makes it highly effective at protecting delicate electronics from spikes and surges. Its wide operating temperature range and excellent resistance to transients ensures reliable operation and long life. By carefully selecting the appropriate MOV, engineers and technicians can ensure the highest level of protection for their equipment.
