Product Description
Product Overview
The Signal ST and DST Series Split/Tran Specialty Purpose & Class 2 Transformers are designed with a dual cavity platform for superior isolation and low capacitive coupling. They feature rigid pin construction for enhanced board insertion reliability. These transformers are suitable for a wide range of power applications, from 1.1 VA to 36 VA, and are built with a Class F insulation system (155C). They offer single or dual primary options (115 V or 115/230 V, 50/60 Hz) and series or parallel secondary configurations. The split bobbin construction eliminates the need for an electrostatic shield. These transformers are RoHS compliant and available in custom versions upon request.
