Product Description

The P7218 A0 magnetic core is a double-sided 3-inch core engineered for high-efficiency transformers and inductors in power electronics. Designed with dual-layer ferrite material, it supports high magnetic flux density (up to 450 mT) and operates within a wide temperature range of -40°C to +125°C, making it suitable for industrial automation, renewable energy systems, and EV charging infrastructure. The core’s compact 76.2mm (3-inch) diameter and symmetrical double-sided design ensure low eddy current loss (<1.5 W/kg at 100 kHz) and excellent thermal stability. While it lacks integrated input/output ports or communication interfaces, its modular structure allows direct integration with windings and cooling modules. Key advantages include high saturation resistance and reduced hysteresis loss, though its rigidity may require precise mounting in vibration-prone environments.
