SKU: A33AB950-B12F-4A64-A08B-77B3E549B455

Enhance your circuit protection and safeguard sensitive electronic infrastructure with the 20D221K Metal Oxide Varistor (MOV). Engineered specifically for robust transient voltage suppression, these 20mm radial disc varistors act as critical frontline barriers against harmful voltage spikes, lightning surges, and switching transients in power and industrial systems. Featuring symmetrical bi-directional characteristics, these components rapidly clamp high transient energies to protect microcontrollers, power supply units, and home appliances from catastrophic overvoltage damage. This convenient 20-pack provides ample components for mass production assembly, prototyping, or routine maintenance repairs.
