Product Description
Product Overview
Signal's LPI series low profile international transformers are designed for low power applications requiring minimal height and reduced magnetic radiation. These transformers feature full encapsulation to meet international safety requirements and harsh environmental conditions. They offer rigid pin construction for easier board insertion and higher reliability, along with mounting holes for enhanced resistance to shock and vibration. The LPI series provides improved electrical characteristics, including better regulation, temperature rise, and efficiency, while also reducing magnetic radiation. They are a direct plug-in replacement for the original FlatHead design.
