ECPE42-21
The ECPE42-21 from B & R Automation is a high-performance magnetic component in the ECP Multi Control Modules series, engineered for demanding industrial applications. Featuring an E-Core shape constructed from premium ferrite material, this module offers stable inductance and low electromagnetic emissions. Rated for a frequency range of up to 500 kHz, it supports advanced power electronics designs with predictable behavior. Compact and robust, the design integrates seamlessly into chassis- or PCB-mounted assemblies with a through-hole configuration. Designed for temperatures from -40°C to +125°C, it ensures reliable performance under thermal stress.
Built for precision and efficiency, the ECPE42-21 exhibits an Al Value (inductance factor) of 4700 nH/N^2, delivering consistent energy transfer in coil designs. The component’s cross sectional area of 205 mm^2 and magnetic path length of 109 mm optimize flux distribution and minimize core losses. With an inner diameter (id) of 22.3 mm and an outer diameter (od) of 48.25 mm, the core provides ample window space for winding configurations. The width of 15.7 mm and height of 21.1 mm balance compactness with mechanical stability. At 25°C, the ungapped ferrite core achieves a saturation flux density of 200 mT, maximizing energy storage before nonlinearity.
Operationally versatile, the ECPE42-21 embraces a universal mounting type—both chassis and through-hole—facilitating rapid prototyping and seamless production line integration. Weighing just 0.30 kg, it adds minimal mass while supporting structural frameworks in motor drives and power modules. Fully RoHS compliant, it aligns with global environmental standards and industrial safety mandates. Its wide operating temperature range ensures thermal resilience and continuous operation in challenging environments. The predictable inductance and low EMI characteristics increase system reliability and reduce the need for additional filtering.
Engineers can integrate the ECPE42-21 directly into compact transformers, inductors, and custom power supplies for applications in industrial automation, motor drives, and energy conversion systems. Its standardized E-Core geometry and robust ferrite construction simplify design iterations and enhance manufacturability. Whether deployed on PCBs, backplanes, or custom chassis assemblies, this module delivers repeatable performance across diverse operating conditions. The ECPE42-21 is the ideal choice for next-generation power electronics where size, efficiency, and reliability converge.
