A snubber circuit protects power supply equipment by preventing the occurrence of high-voltage spikes during switching. The capacitor component in the circuit absorbs surge voltage generated by the inductance of the transformer or wiring and protects switching elements and peripheral components. As the use of compact internal modules becomes increasingly widespread in automotive and industrial equipment, there is a growing need for miniaturized electronic components that are capable of withstanding high temperatures.
According to the vendor, these new MLCCs provide lower loss and produce less heat when compared to similar products using ceramic with a high dielectric constant. Because they use temperature compensating ceramic with minimal capacitance variation, these solutions can handle large voltages during switching, the company promises.
