Product Description

The P7219 A1 Double-sided 3-inch core is a high-performance magnetic core component designed for industrial applications requiring efficient energy transfer and electromagnetic compatibility. Featuring a double-sided ferrite core structure with a compact 3-inch diameter, this core offers robust magnetic flux management, supporting voltage ranges from 12V to 48V DC and operating temperatures between -40°C and +125°C. It integrates seamlessly with power supply modules, transformers, and inductors, providing dual input/output terminals for flexible circuit integration. The core’s low-loss ferrite material enhances energy efficiency, making it ideal for power electronics, renewable energy systems, and automotive industries. While its compact size optimizes space utilization, the 3-inch magnetic core components may require precise alignment during installation. The core lacks built-in communication interfaces or battery support, focusing solely on magnetic performance.
