GRF172D Datasheet | Teledyne Technologies

DESCRIPTION The GRF172 surface-mount Centigrid® relay is an ultraminiature, hermetically sealed, armature relay for 2.5 GHz RF applications. Its low profile height (.330”) and .100” grid spaced terminals make it an ideal choice where extreme packaging density and/or close PC board spacing are required. The GRF172 features a unique ground shield that isolates and shields each lead to ensure excellent contact-to-contact and pole-to-pole isolation. This ground shield provides a ground interface that results in improved highfrequency performance as well as parametric repeatability. The GRF172 extends performance advantages over similar RF devices that simply offer formed leads for surface mounting. Unique construction features and manufacturing techniques provide overall high reliability and excellent resistance to environmental extremes: - All welded construction. - Unique uni-frame design providing high magnetic efficiency and mechanical rigidity. - High force/mass ratios for resistance to shock and vibration. - Advanced cleaning techniques provide maximum assurance of internal cleanliness. - Precious metal alloy contact material with gold plating assures excellent high current and dry circuit switching capabilities. Applications include telemunications, test instruments, mobile munications, attenuators, and automatic test equipment.
