The Bel Fuse Signal ST and DST Series Split/Tran Specialty Purpose & Class 2 Transformers are designed with a dual cavity platform, offering superior isolation and low capacitive coupling. These split bobbin transformers feature rigid pin construction for enhanced board insertion reliability. They are suitable for a wide range of power applications from 1.1 VA to 36 VA, with single or dual primaries and series or parallel secondaries. The inherent split bobbin construction eliminates the need for an electrostatic shield, and they are built with a Class F, 155C insulation system.
