4-1393789-3 is an AXICOM SMT relay from TE Connectivity designed for telecom, signal, and RF applications. The relay is dry packed due to moisture sensitivity and requires soldering within a defined time based on its moisture sensitive level (MSL). It supports reflow soldering with a peak package body temperature of 250°C and should be stored in sealed bags at less than 40°C and 90% relative humidity for up to 36 months. These relays are suitable for applications requiring robust and reliable electromechanical switching performance.
