MOV-20D680K are varistors that are widely used in various electrical circuits to suppress surges & spikes in the operating voltage. They are an important component in circuit protection, as they help to maintain a certain throughput of power and thus protect the circuit from thermal or electrical breakdown. MOV-20D680K varistors are devices that use a sacrificial material to alter the current flow in an electronic circuit and prevent it from exceeding a certain threshold. This protects the components in the circuit as well as the circuit itself from damage.

MOV-20D680K are made from a combination of polymeric material and metal oxides. The metal oxide is used to absorb excess or high electrical energy during surges and spikes, while the polymeric material works as a dielectric. It acts as a buffer between the input and output voltage, preventing high voltage from damaging the electronic components. MOV-20D680K can be used in a variety of applications, such as circuit protection, power conditioning, power surge protection, and industrial automation.

The MOV-20D680K device works by redirecting the excess voltage that could damage the circuit and its components, and diverting it into a power dissipation path. When the device reaches its breakdown voltage, it triggers an electrical spark and creates an ionization of the mediator that is used as the protection material in the device. This “explosive” reaction dissipates the energy of the applied voltage, so that the circuit is not damaged. This process is known as “clamping”, as it prevents the voltage from exceeding a certain limit. Another important feature of these devices is that their clamps can be adjustable, which allows them to be customised for different application requirements.

MOV-20D680K varistors are available in a variety of form factors, including surface mount technology (SMT) and through-hole technology (THT). They are ideal for use in handheld equipment, computers, gaming consoles, industrial machinery, and other consumer electronics. Their small size and low leakage current make them suitable for high-temperature environments and for use in industrial automation. The MOV-20D680K is also very reliable, and its long service life makes it a popular choice for many applications.

In summary, MOV-20D680k varistors are a type of surge protector that is designed to protect circuits from voltage spikes and surges. They are made from a combination of polymeric material and metal oxide, and work by redirecting the excess voltage into a power dissipation path. They are available in a variety of form factors, and can be customised for different application requirements. They are very reliable and long-lasting, making them a popular choice for a variety of applications.
