Designed as critical infrastructure guardians against electromagnetic warfare, HEMP filters are capable of withstanding transient electromagnetic fields up to 50 kV/m, in full compliance with MIL-STD-188-125. These rugged filters ensure uninterrupted system operation through zero-downtime failover during high-energy EMP events. Validated by China’s State Key EMC Laboratory for shielding effectiveness up to 40 GHz, they are trusted to protect high-stakes environments such as nuclear power plant control systems and satellite ground stations. Their dual certification to both MIL-STD and GJB standards guarantees reliability for military EMP protection and the hardening of essential civilian infrastructure.
