Series S172 DPDT Non-Latching Commercial Electromechanical Relay CENTIGRID SURFACE MOUNT COMMERCIAL RELAYS DPDT SERIES RELAY TYPE S172 DPDT basic relay S172D DPDT relay with internal diode for coil transient suppression DESCRIPTION The S172 surface mount Centigrid relay is an ultraminiature, hermetically Unique uni-frame design providing high magnetic efficiency and sealed, armature relay for commercial applications. Its low profile height mechanical rigidity. (.470) and .100 grid spaced terminals make it an ideal choice where Advanced cleaning techniques provide maximum assurance of extreme packaging density and/or close PC board spacing are required. internal cleanliness. The specially formed leads are pre-tinned to make the relays ideal for all Precious metal alloy contact material with gold plating assures excellent types of surface- mount solder reflow processes. high current and dry circuit switching capabilities. The basic design and internal structure are similar to Teledynes DPDT The S172D relay has an internal discrete silicon diode for coil transient 114 Centigrid relay. Unique construction features and manufacturing suppression. techniques provide overall high reliability and excellent resistance to environmental extremes: The S172 feature: All welded construction. High force/mass ratios for resistance to shock and vibration.
