High-Altitude Electromagnetic Pulse HEMP Filter GPF252C-32/EMP
Product Description
█Description
HEMP stands for High-Altitude Electromagnetic Pulse, which is an abrupt and high-intensity broadband electromagnetic pulse radiation generated by high-altitude nuclear explosions.
In addition to conventional filtering circuits, the HEMP filter also incorporates transient pulse suppression circuits. This ensures that the product, while filtering out typical interference and noise, meets the protection requirements for lightning-induced electromagnetic pulses and HEMP. It complies with the standards outlined in MIL-STD-188-125-1-1998 and MIL-STD-188-125-2-1999.
HEMP filters are widely used in military, aerospace, power, and communication sectors to ensure the proper operation and protection of critical equipment.
