Distinctive features ENTIRELY DESIGNED FOR SURFCE MOUNT Surface mount devices (SMD) are subjected to more stringent constraints of temperature, solderability and space savings than through-hole components. To meet these requirements, has designed a range of surface mount switches including 3 product types : - pushbutton switches, TP series - slide switches, TG series - toggle switches, TL series Tape and reel packaging This type of packaging is recommended for the following reasons : - economy, - suitability for automated placement - large number of components per packaging unit - good component positioning - protection of terminals against damage during handling - high static resistance Reflow solderable High temperature plastic materials Tin plated ground plate Terminal coating : tin-lead alloy aver nickel plating Terminals turned to the outside, preventing the shadow effect in infrared soldering and permitting visual inspection of solder joints Distance between case and circuit : 0,55 mm (.021) End stackable with 10,16 mm (.40) pitch vailable with positioning pins to ensure switch orientation during the reflow process and increasing switch mechanical resistance Pushbutton and toggle models protected against electrostatic discharges (ESD) up to 10 KV Washable Construction withstands cleaning processes, including hot water under pressure -6
