Product Description
Small EI Transformer Core
Our Small EI Transformer Core is a high-performance magnetic component engineered for efficient power conversion and signal isolation in compact electronic devices. Utilizing precision-stamped silicon steel laminations, this core forms the essential component of small transformers, inductors, and chokes. The classic interlocking design ensures a robust magnetic circuit with minimal air gaps, maximizing magnetic flux linkage for reliable performance in low to medium-power applications.
Typical Applications
  • Switch-Mode Power Supplies (SMPS) for consumer electronics
  • AC/DC adapters and chargers
  • Audio equipment input/output transformers
  • Control circuits, relays, and small power supplies
  • Lighting ballasts and LED drivers
