EI/UI/SD Core Series - High Performance Magnetic Cores for Power and Signal

EI/UI/SD Core Series – Versatile magnetic cores designed with distinct geometries to optimize inductance, reduce losses, and suit diverse electrical applications.

The EI/UI/SD Core Series consists of three core types crafted from high-quality ferrite, silicon steel, or amorphous metal materials. Each core’s unique geometric design addresses specific magnetic requirements in power conversion, signal processing, and inductive applications. These cores are widely used in transformers, inductors, and filters due to their efficient magnetic coupling, low leakage, and reliable mechanical stability.

Magnetic Performance Adaptability

EI - Core ensures efficient magnetic coupling with low leakage, ideal for stable power transfer. UI - Core allows adjustable inductance via air - gap control (tuning via “I” - lamination thickness), perfect for tunable filters. SD - Core offers ultra - low loss/high saturation flux density through custom materials (e.g., nanocrystalline alloys) and geometries, meeting extreme application demands.

Design & Manufacturing Flexibility

EI - Core’s simple stamping process enables low - cost, mass production. UI - Core’s modular “U + I” structure simplifies assembly and maintenance. SD - Core supports custom geometries (e.g., complex shapes for unique magnetic field patterns), catering to niche applications like high - frequency power supplies or precision sensors.

Application - Specific Efficiency

EI - Core excels in power - frequency (50Hz/60Hz) distribution transformers. UI - Core suits RF tunable filters and inductive sensors. SD - Core targets high - efficiency, high - frequency systems (e.g., telecom switching power supplies) with minimal losses.
