What RF Immunity does

RF Immunity Ltd. is an Israel-based (Yavne) specialty manufacturer of EMI/RFI filter connectors, transient and lightning protection connectors, hermetically sealed connectors, military filter units, power conditioning products, and custom cable and harness assemblies, serving military, aerospace, industrial, and medical equipment OEMs. The company was founded in 2002 and operates as a privately held subsidiary of Teder Electromechanical Engineering, with 26 employees and AS9100D plus ISO 9001:2015 quality certification. Its core technology revolves around filter connector topologies (C, L, J, Pi, T) with integrated transient suppression, lightning protection per RTCA/DO-160E Section 22, and hermetic sealing achieving less than 10⁻⁵ cm³/s leak rates. The firm's proprietary Customized Mass Production Technology (CMPT) platform is the central architectural asset, enabling flexible manufacturing of both catalog and engineered solutions with per-pin filter and protection configuration.

RF Immunity monetizes predominantly through hardware sales of filter connectors, military power units, and cable assemblies, augmented by professional services for turnkey custom design, EMC testing, and environmental qualification. Pricing is quote-based, with a $1,000 minimum order value and a $25 surcharge for sub-threshold transactions; products are predominantly one-time/perpetual license sales. The go-to-market combines an enterprise field sales motion headquartered in Israel with a global distributor network spanning more than 20 partners across North America, Europe, and Asia-Pacific (including PEI-Genesis multi-region, Gemini Electronic Components, Guest Associates, and MSA Components), supplemented by technical seminars, white papers, trade-show presence (notably Aero India 2025), and LinkedIn-driven corporate communications. Named end customers include the Israeli Defense Forces, Airbus (A400M program), an Israeli UAV OEM, and the German military sector, indicating a defense and aerospace core with adjacent medical and industrial exposure.
