Welcome to your one-stop shop for varistors, the essential components for safeguarding electrical circuits from voltage spikes and surges. These devices are crucial in maintaining the longevity and reliability of your electronic systems. Whether you're dealing with power surges or transient voltage spikes, varistors provide the protection your equipment needs.
Varistors, often referred to as voltage-dependent resistors, are designed to protect circuits by clamping high voltage levels. When voltage exceeds a certain threshold, varistors absorb the excess energy, preventing damage to sensitive components. This makes them indispensable in environments where voltage fluctuations are common.
Our collection includes a wide range of metal oxide varistors (MOVs), known for their durability and efficiency. These MOVs are crafted from metal oxide materials, offering excellent clamping capabilities and high energy absorption. They are ideal for applications requiring robust protection against high voltage transients.
Explore our selection of TVS varistors, perfect for applications that demand rapid response to voltage spikes. These devices are engineered to react quickly, ensuring your circuits remain safe from sudden surges. With a variety of sizes and specifications, you can find the perfect fit for your specific needs.
Understanding the difference between a varistor and a resistor is key. While resistors provide a constant resistance, varistors offer variable resistance based on the voltage level. This unique property allows varistors to protect circuits by absorbing excess voltage, unlike resistors that simply limit current flow.
In the event of a varistor failure, the device typically short-circuits, which can lead to circuit interruption. It's crucial to regularly inspect and replace varistors to maintain optimal circuit protection. Without a varistor, circuits are vulnerable to voltage spikes, which can cause irreversible damage to electronic components.
Our varistors are sourced from leading brands, ensuring quality and reliability. With on-demand access to these essential components, you can keep your operations running smoothly. Trust in our range of varistors to provide the protection your systems deserve.
What is a varistor used for?
Varistors are used to protect electrical circuits from voltage spikes and surges by clamping excessive voltage levels and absorbing the excess energy.
What is the difference between a varistor and a resistor?
Varistors offer variable resistance based on voltage levels, protecting circuits from surges, while resistors provide constant resistance to limit current flow.
What happens when a varistor fails?
When a varistor fails, it typically short-circuits, potentially interrupting the circuit and leaving it vulnerable to voltage spikes.
Can a circuit work without a varistor?
While a circuit can function without a varistor, it remains susceptible to damage from voltage spikes, which can harm sensitive electronic components.
