MOV-14D820K

TVS (Transient Voltage Suppressors), also known as Varistors, and MOVs (Metal Oxide Varistors) are two types of electrical components designed to both absorb and redirect energy from electrical surges and other forms of voltage transients. The MOV-14D820K is a type of MOV produced by Momentive Performance Materials Inc.. It features energy ratings of 5kA and 40 VAC, it operates at 50 Volts, and can enable high-speed surge protection in applications requiring products with longer operating life and high-power capability.

The MOV-14D820K is designed to protect a connected electric device from surges or transient voltage and electrical spikes that may be harmful due to their high voltage and current. As such, it is ideal for use in applications requiring superior levels of surge protection such as consumer electronics, industrial electronics, communications, and automotive electronics.

MOV-14D820Ks operate using a unique construction in which different layers of zinc oxide, an electrically conductive element, are coupled in parallel to create a high-impedance. This forms an electrical protection switching element with a higher amount of resistance when struck by high-voltage electrical transients.

The simple physics behind this surge protection system work as follows. When the MOV is struck by a surge, the low-impedance zinc oxide layer absorbs the energy from the transient voltage. When the energy in the surge reaches a specific level, the high-impedance layer prevents it from dissipating further, thus redirecting the energy away from the connected device so it is not damaged.

The energy that is redirected by the MOV is typically sent back into the electrical system, directing it far from the protected device. While the MOV itself may be rendered inactive, the surge protection provided by the device has been successful in preventing electrical damage. The MOV-14D820k is an excellent choice for protection applications requiring a combination of high voltage and current performance with a long operating life.

Overall, the MOV-14D820K is a reliable and effective device that can effectively protect a device from electrical damage due to high-voltage transient voltage and power surges. Due to its low impedance and simple yet effective construction, it can provide superior levels of surge protection while being as reliable and efficient as possible.
