The SMU series offers a maximum power dissipation of 1/4 watt. The SMU is designed to keep the lowest profile. This is done by having the adjustment location on the top of the potentiometer. The adjustment of the full range of resistance can be accomplished with a single turn. This provides the user with a quick adjustment. The adjustment can also be completed with either a flat head or “Phillips” screw driver, adding another layer of ease for the user. The SMU series is offered in standard values from 50 ohms up to 2M ohms and the outer casing meets UL 94V-0 requirements.
