Product Description

Product Overview

The Signal ST/DST Series Split/Tran Specialty Purpose & Class 2 Transformers are designed for printed circuit board mounting, utilizing a dual-cavity platform that provides superior isolation and low capacitive coupling. These transformers feature rigid pin construction for easier board insertion and enhanced reliability. They are suitable for a wide range of power applications from 1.1 VA to 36 VA, offering dielectric strength of 2500 Vrms Hipot. Available in single or dual primary configurations (115 V or 115/230 V, 50/60 Hz) with series or parallel secondary options, these transformers meet Class F insulation system standards (155C) and are RoHS compliant. Agency certifications include UL and CSA recognition.
