Product Description
Product Overview
The Bourns 3313 Series is a 3 mm square, single-turn cermet trimming potentiometer designed for surface mount applications. It is compatible with standard surface mount manufacturing processes and offers a rotor stop for in-circuit adjustment. With a rotational and seal life of 100 cycles, it is suitable for RF applications due to its plastic housing. The series is RoHS compliant, with halogen-free models available (identified by a black housing color). It is not recommended for wave soldering.
