Product Description
Product Overview
The Signal ST/DST Series Split/Tran Specialty Purpose & Class 2 Transformers are designed for printed circuit board mounting, featuring a split bobbin construction with dual cavities that provide superior isolation and low capacitive coupling. This design eliminates the need for an electrostatic shield. The transformers offer 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, and are available with single or dual primaries (115 V or 115/230 V, 50/60 Hz) and series or parallel secondaries.
