CoF filter connectors

ITT Interconnect Solutions has improved its Chip-on-Flex (CoF) filter connectors with TVS Surge (TVSS) suppression capabilities. The new CoF filter design features one standard flex per layout and utilizes a flexible circuit internal to the connector, with chip capacitors surface-mounted on a small pad adjacent to the feed-thru contact.

"The flex circuit design provides the necessary platform to surface mount TVS devices for lightning strike protection," said Keith Teichmann, director of marketing for ITT Interconnect Solutions. "This allows us to mount off-the-shelf devices for both filtering and surge protection using automated manufacturing processes, resulting in a highly cost-effective, compact, and lightweight design while still providing the robust, high performance filter connector required of many applications, including those in the military arena."

Tested to MIL-DTL-38999 Series III mechanical shock, vibration and high altitude DWV specifications, the CoF filter connectors exceed 1000 cycles of thermal shock per MIL-STD-1344. The CoF connectors feature contact count counts from one to 600 and are available in rack and panel, circular and D-subminiature configurations. The compact, lightweight connectors provide up to 15 percent space savings compared to standard MIL-DTL-38999 configurations.

Customizable circuit values are also available by adding or removing the chip capacitor and TVS devices. ITT also offers complete design and design change capabilities.

Typical pricing for the Chip-on-Flex filter connectors is approximately $175 each. Lead time is from 12 to 14 weeks ARO.
