B72240L0461K100

The B72240L0461K100 is a widely used Metal Oxide Varistor (MOV) with a resistance range of 4.6K to 10K Ω. It is typically used to protect electrical and electronic equipment against voltage spikes, or transient over-voltage. This is done by quickly reducing the surge voltage to a lower level when it exceeds its clamping voltage rating of 72V.

The B72240L0461K100 is composed of a series of metal-oxide layers and is encased in an epoxy resin housing. The outer metal plates are connected to its two terminals and serve as the electrodes of the MOV. When a surge of voltage enters into the device, electrons from the metal-oxide layers are transferred between the two electrodes. This forms an avalanche junction which quickly creates a low resistance area and diverts the current away from the protected equipment.

The series of metal-oxide layers also determine the clamping voltage of the B72240L0461K100. When the surge voltage exceeds its specified clamping voltage, a large current surge will be created which limits the amount of voltage that will pass through. This is the primary function of the B72240L0461K100, as it prevents the voltage from exceeding 72V and damaging the circuits or components connected to it.

The B72240L0461K100 is typically used in various applications, such as automotive, power supplies, medical equipment, and telecom/data communications. It is ideal for applications where the need for circuit protection against transient over-voltage is required. The device can also be used as an electrostatic discharge (ESD) protection device, as it can absorb large amounts of electrostatic energy without being damaged.

Overall, the B72240L0461K100 is a reliable and cost-effective over-voltage protection device that is used in a wide variety of applications. The device is easy to install and requires minimal maintenance, making it an excellent choice for protecting electrical and electronic components from transient voltage spikes.
