The Bourns MOV-10DxxxK series of metal oxide varistors (MOVs) are designed to protect sensitive electronic circuits from overvoltage transients such as lightning strikes, power contact, and power induction. These devices offer a choice of varistor voltages and Vrms voltages, along with high current handling and fast response times. They are commonly used in power supplies, power systems, line voltage applications, telecom systems, white goods, and appliances. The MOV-10D470K specifically provides reliable surge protection with a 47V varistor voltage and is RoHS compliant, ensuring environmental responsibility.
