Product Description

Product Overview

The Signal LPI Series Low Profile International Transformers are designed for low power applications requiring minimum height and reduced magnetic radiation. These transformers feature full encapsulation to meet international safety requirements and harsh environmental conditions. With rigid pin construction for easier board insertion and higher reliability, they offer improved electrical characteristics including regulation, temperature rise, and efficiency. Mounting holes are provided for enhanced resistance to shock and vibration. They are a direct plug-in replacement for the original FlatHead design.
