0402L100SLKR

Littelfuse Inc. 0402L100SLKR in the PTC Resettable Fuses category is typically selected when engineers need predictable, spec-driven behavior in a production design. A coordinated protection strategy improves safety and reduces costly field failures. They protect circuits and users from overloads, surges, ESD, and overheating events that cause downtime and safety risk. 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. Overall, it improves predictability by keeping key performance stable across manufacturing variance and operating conditions.
