Additional Details:

The B72210S141K101V87 MOV is characterized by its varistor voltage, surge current capability, and energy absorption capability. The varistor voltage is the voltage at which the MOV begins to conduct significantly, clamping the voltage to a safe level. The surge current capability is the maximum surge current that the MOV can withstand without failure. The energy absorption capability is the amount of energy that the MOV can absorb during a surge event.

MOVs operate by changing their resistance in response to voltage changes. When the voltage across the MOV exceeds its varistor voltage, the resistance decreases rapidly, allowing the MOV to conduct the surge current and clamp the voltage. This protects the downstream electronic components from the surge.

EPCOS (TDK) is a leading manufacturer of MOVs, offering a wide range of products for various applications. Their MOVs are known for their high quality, reliability, and performance.
