Product Description
Product Overview
The Signal ST and DST Series Split/Tran Specialty Purpose & Class 2 Transformers are designed for applications requiring superior isolation and low capacitive coupling. Utilizing a dual cavity platform, these transformers offer 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, with dielectric strength of 2500 Vrms Hipot. Available in single or dual primary configurations (115 V or 115/230 V, 50/60 Hz) and series or parallel secondaries, these transformers are built with a Class F (155 C) insulation system. Electrostatic shielding is not necessary due to the split bobbin construction. Custom versions are available upon request.
