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. Utilizing a split bobbin with dual cavity construction, these transformers eliminate the need for electrostatic shields. They feature rigid pin construction for enhanced board insertion reliability and are available in a wide range of power ratings from 1.1 VA to 36 VA. These transformers are suitable for various signal and power applications and are offered in both single (ST) and dual (DST) primary configurations, supporting 115V or 115/230V input at 50/60 Hz. They are RoHS compliant and carry multiple agency certifications for safety and performance.
