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