SMT TR
New product
Surface mount tiny washable rocker switches, single pole configurations.
Main features
- Entirely designed for surface mount
- Tape and reel packaging
- Reflow solderable
- High temperature plastic materials
- Tin plated ground plate
- Terminal coating : tin alloy over 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
- Available with positioning pins to ensure switch orientation during the reflow process and increasing switch mechanical resistance
- Protected against electrostatic discharges (ESD) up to 10 KV
- Washable : Construction withstands cleaning processes, including hot water under pressure
