Product Description
Product Overview
The Signal ST/DST Series Split/Tran Specialty Purpose & Class 2 Transformers are designed for applications requiring superior isolation and low capacitive coupling, thanks to their split bobbin construction with dual cavities. These transformers feature rigid pin construction for easier board insertion and enhanced reliability. They are suitable for a wide range of power requirements from 1.1 VA to 36 VA 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 insulation system meets Class F (155 C) standards, and the transformers are RoHS compliant.
