The Rosel holding (part of Rostec) has begun state testing of Podorozhnik electromagnetic chip filters. Passive devices are mounted on printed circuit boards by surface mounting and are designed to suppress powerful impulse noise generated during the operation of electronic warfare equipment. Such voltage surges in power circuits and signal lines can disable sensitive electronics of radars, communication and navigation systems, the state corporation explained.
The filters cut off dangerous interference on critical lines, preventing burnout of microcircuits and sensors. This ensures stable operation of field telephones, radio stations and airborne electronic equipment of drones in a complex interference environment. The operating temperature range is from −60°C to +125°C, the declared operating time is 20 thousand hours, which guarantees trouble-free operation throughout the 25-year service life of the final equipment.
The installation batch of filters has already been submitted for state testing. The use of "Podorozhnik" allows you to maintain the functionality of devices when exposed to electronic warfare equipment, eliminating both temporary failures and complete degradation of the component base. The development closes the niche of domestic interference protection elements for airborne electronics, which is critical in an environment of active electronic warfare.
