Tempest EMI Filters
For safe power and data protection
Comprehensive EMI Solutions with Tempest Filters
Tempest filters are specially designed electromagnetic interference (EMI) filters. Tempest stands for Transient Electromagnetic Pulse Emission Standard; "TEMPEST" stands for a specific standard for controlling electromagnetic emissions to protect sensitive environments. These filters are designed to meet the stringent, recognized TEMPEST standards for military and government applications, preventing electronic eavesdropping and controlling electromagnetic emissions.
DOREXS, a leading supplier of TEMPEST EMI filters, understands the importance of data security. Our Tempest filters are manufactured in state-of-the-art facilities with comprehensive in-house manufacturing processes and rigorous quality control. Our experience in producing military components and Tempest power line filters for the defense industry allows us to meet demanding requirements, setting us apart from the competition.
We also offer a wide variety of defense EMI power line filters and related solutions. DOREXS keeps a wide range of Tempest filters in stock and available for immediate shipment.
