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 are ideal for harsh environmental conditions. They offer improved electrical characteristics, including regulation, temperature rise, and efficiency, along with rigid pin construction for easier board insertion and enhanced reliability. Mounting holes are provided for greater resistance to shock and vibration. The LPI series serves as a direct plug-in replacement for original FlatHead designs.
