Interposer Connectors

Interposers are a high-reliability, customizable way of connecting two PCBs, specifically designed for the aerospace industry. They feature spring-loaded contacts, which enable easy, solderless installation and removal. This provides a direct connection, thus eliminating the need for a wired solution and allows for effortless mating and unmating, making design and integration straightforward. To maximize design flexibility, Littelfuse has created an easy-to-use “build-an-interposer” concept. This enables customers to mix and match options to create the interposer they need for their particular application. The new interconnect uses proven Starclip contact technology. This means that the electrical contact function is decoupled from the pressure applied by the spring, which therefore enables the connector to provide a stable, low-contact resistance, regardless of the force applied or distance moved. Expected applications include space equipment, satellite payloads, high-performance avionics/military, and engineering test equipment. The interconnects are non-outgassing with gold-plated contacts and have an operating temperature range of -55°C to +125°C. They are compliant with CS FR051 C&K^® specification, according to ESA/ESCC code 3401. The interconnects have a minimum distance between the two contacts of 1.27 mm and a minimum height of 8 mm. Contact resistance is a low 25mΩ, with a rated current of 1.5 A and a working voltage of 100 or 200 Vrms."
