Our EMI/RFI range of components are highly customizable with the ability to meet the customer’s requirements in shape, size and technical specifications. Our innovative and agile components can be used on a range of applications from power and signal filtering for defence and aerospace equipment, for radar, communication, shielded and secure rooms.
Film capacitors provide Corona-free performance, low inductance, and high energy density. They capacitors are available in a variety of mounting styles, and since film capacitors are non-polarised they can be installed randomly into a circuit.
Capacitors employing reconstituted mica exhibit minimal capacitance drift over time and temperature during a long life of reliable performance. Frequently recommended for high voltage applications.
We have a full range of Tubular or Cylindrical filters for different applications.
Filters qualified to Mil-PRF-15733 are available, which offer the greatest number of qualifications for the most popular filter mil spec. Catalog sheets reference the appropriate qualified mil spec numbers for easy cross-reference. Upon request, we can also propose a non-QPL option.
For applications requiring Higher Reliability, the RF6900 Series was designed and developed according to Mil-PRF-28861. These filters are available in many circuit configurations and are certified to meet all the applicable requirements.
A third type, the Sprague cylindrical filter, remains a popular option for engineers seeking an excellent military-grade catalogue filter. These have been the filter of choice on many defence platforms and continue to be a trusted choice.
We design and manufacture EMI/ RFI filters in virtually any shape and size. Most filters in this “Rectangular” category are the result of an open exchange of technical details between us and the end-user. While rectangular-shaped packaging is the more common, we can accommodate an application’s unique requirements for size, weight, shape, termination, or mounting without compromising performance.
Popular applications include power and signal filtering for defence and aerospace equipment, for radar, for communication, for shielded and secure rooms, and others.
For applications that may involve Transient Voltages or Electro-Magnetic Pulse (EMP) technical information that is specific to these applications are also available.
We have a range of EMI/RFI filters that are designed to protect circuits against very high energy transient events. Examples include:
- Electromagnetic pulse (EMP)
- Lightning strike
- High altitude EMP (HEMP)
- Solar activity
- Nuclear explosion (NEMP)
EMI filters are specifically designed to reduce emissions and lessen susceptibility for compliance to Mil-STD-461. The filters will comply with the restrictions on Leakage Current for both 60Hz and 400 Hz power systems but are characterised with Insertion Loss data directly related to the Mil-STD-461 testing methods.
Applications for these filters are found in many commercial and private test laboratories, and at the secure room installations in military and diplomatic facilities. All FILTRON products are made in America at our facilities. Examples include a telephone line filter that is available in multi circuit assemblies, and a power line filter which is designed to be direct-mounted through the wall of a shielded room or cabinet.
TEMPEST lowpass power filters are deployed in defence and in private installations to prevent power lines and other outlets from acting as transmitters of electronic data. With a TEMPEST filter, sensitive information will not become conducted EMI signals leaking from PCs, servers, telephones, etc. These filters are recommended for use in shielded rooms, secure communication areas, as well as in shipboard electronic installations. Pictured is one of many possible TEMPEST filter designs.
