CoF filters from ITT Interconnect Solutions provide platform for filtering and surge protection of new TVSS devices

This flex circuit design provides the necessary platform for surface mount TVS devices for lightning strike protection. Off the shelf devices for both filtering and surge protection can be mounted using an automated manufacturing process. The result is a very cost effective, reliable, light weight and compact design, benefiting from the robustness and thermal as well as mechanical performance associated with ITT Interconnect Solutions’ Chip-on-Flex products.

CoF filters offer customisable, individual circuit values by adding or removing the chip capacitor and TVS devices. A wide range of capacitance and TVs values is available. Tested to Mil-DTL-38999 Series III standards for mechanical shock, vibration, and high altitude DWV, CoF components exceed 1000 cycles of thermal shock as per Mil-Std-1344. The devices feature contact counts from 1 up to 600 and benefit from multiple configurations, including rack & panel, circular and D-Sub.

ITT Interconnect Solutions offers its customers complete design and design change services for its CoF devices. The components are available at very short lead times of ten weeks (reduced from 16 weeks).
