Product Description
Product Overview
Signal's ST and DST Series Split/Tran Specialty Purpose & Class 2 Transformers are designed for printed circuit board mounting. These transformers utilize a dual cavity platform to provide superior isolation and low capacitive coupling. The rigid pin construction ensures easier board insertion and higher reliability. They are suitable for various applications requiring signal and power isolation, with options for single or dual primaries and series or parallel secondaries. These transformers are RoHS compliant and available in custom versions upon request.
