Rugged Magnetic-Latching Relay Goes To The Extreme

The ultraminiature RF180 4.5-GHz relay features low intercontact capacitance for high-end RF performance through and beyond the UHF spectrum. This magnetic-latching relay, designed to operate at high frequencies, provides shock, vibration, and temperature resistance for use in space applications and other extreme environments. The part is hermetically sealed and available in coil voltages of 5, 12, and 26.5 V dc. It has a low profile and 0.100-in. grid-spaced terminals, suiting it for applications where high packaging density or close pc-board spacing is required. The RF180's all-welded construction and uniframe design provide high magnetic efficiency and mechanical rigidity. The relay measures 0.475 by 0.375 by 0.300 in., (excluding leads) and weighs 2.9 g. Operating from −65°C to 125°C, the RF180 suits RF attenuators, RF switch matrices, automated test equipment, and spacecraft. It costs $35.85 each in 500-unit quantities.
