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