Micro relays serve as remarkably small electromechanical relays laying claim to a width <=15 mm ideal for low-power electronic circuits, thus making them ultracompact. These micro relays boast surface mount (SMT) or through-hole (THT) terminals as well as a coil power of 50 mW. Their signal relays lying in the range <=2A along with power micro relays (up to 10A) operate with small motors. Micro relays are additionally favorable for medical devices IoT sensors, and additional AI tech enabled devices due to them having gold plated contacts that enable reliable operation along with low voltage signals starting from 50 mV to faltering vertically as low as 50 mV). Other advantages of micro relays include being RoHS compliant along with having lead free constructions. Thus entails micro relays being a boon for electronics all over the globe due to their compliance with international standards.
