Product Overview
The Signal ST and DST Series Split/Tran Specialty Purpose & Class 2 Transformers are designed for printed circuit board mounting. They utilize a dual cavity platform to provide superior isolation and low capacitive coupling. The rigid pin construction ensures easier board insertion and higher reliability. These transformers are suitable for a wide range of power applications, from 1.1 VA to 36 VA, and are available in single or dual primary configurations with various secondary voltage and current ratings. They are built with a Class F (155 C) insulation system and meet stringent agency certifications including UL and CSA standards.
