EC42 Magnetic Electric Power Transformer Ferrite Core High Frequency Transformer

1.Product Description

The EC42 Magnetic Electric Power Transformer with Ferrite Core is engineered for high-frequency applications from 100kHz to 1MHz, delivering exceptional efficiency up to 96% in compact power conversion systems. Its EC42 ferrite core (PC40/PC95 material) minimizes core losses at elevated frequencies, while the planar winding structure reduces skin effect and proximity losses, ensuring optimal performance in SMPS, LED drivers, and renewable energy inverters. With a power range of 100-1000W and isolation voltage of 3000VAC, it meets safety standards for industrial and automotive applications. The transformer’s low-profile design and thermal management features enable operation from -40°C to +125°C, making it ideal for space-constrained, high-reliability environments such as EV charging modules and telecommunications power supplies. Compliant with UL60950-1 and IEC62368-1, this transformer combines advanced magnetic materials with precision engineering to deliver reliable, efficient power conversion in high-frequency applications.
