In practice, ePCOS - TDK Electronics B72220S0381K101 shows up under Varistors, MOVs when designers want a well-bounded, datasheet-driven building block instead of a fragile board-level workaround. In practice, they protect circuits and users from overloads, surges, ESD, and overheating events that cause downtime and safety risk. They limit damage during overloads, surges, and ESD so faults do not cascade into expensive downstream failures. Within telecom and networking, protection reduces downtime from cable faults in always-on racks. In telecom and networking, protection reduces downtime from cable faults and hot-plug events in always-on racks. In measurement equipment, well-chosen protection prevents input damage while preserving accuracy and low leakage.
