The RFI SPECIALTY COMPONENTS program brings together from one source a full range Tubular, or Cylindrical, filters for different applications:
Filters qualified to Mil-PRF-15733 are available from Ultra EMS, which offers 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 EMS 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 catalog filter. These have been the filter of choice on many defense platforms and continue to be selected by today’s design engineers.
