Product Description
Product Overview
The Signal 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 are ideal for harsh environmental conditions. Benefits include rigid pin construction for easier board insertion and higher reliability, mounting holes for enhanced resistance to shock and vibration, improved electrical characteristics such as regulation, temperature rise, and efficiency, and reduced magnetic radiation. They serve as a direct plug-in replacement for original FlatHead designs.
