CENTIGRID® SURFACE MOUNT COMMERCIAL RELAYS SERIES S172 DPDT SERIES DESIGNATION RELAY TYPE S172 DPDT basic relay S172D DPDT relay with internal diode for coil transient suppression INTERNAL CONSTRUCTION DESCRIPTION The S172 surface mount Centigrid® relay is an ultraminiature, hermetically UNI-FRAME sealed, armature relay for commercial applications. Its low profile height (.470) ARMATURE and .100" grid spaced terminals make it an ideal choice where extreme UPPER STATIONARY CONTACT packaging density and/or close PC board spacing are required. The specially MOVING CONTACT formed leads are pre-tinned to make the relays ideal for all types of surface- LOWER STATIONARY CONTACT mount solder reflow processes. The basic design and internal structure are similar to Teledyne’s DPDT 114 CENTIGRID® AND TO-5 Centigrid® relay. 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 ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS –65°C to +125°C Temperature Storage (Ambient) Operating –55°C to +85°C rigidity. • High force/mass ratios for resistance to shock and vibration. • Advanced cleaning techniques provide maximum assurance of internal cleanliness. Vibration (General Note 1) 10 g’s to 500 Hz Shock (General Note 1) 30 g’s, 6 msec, half-sine Enclosure Hermetically sealed Weight 0.15 oz. (4.3g) max. The S172D relay has an internal discrete silicon diode for coil transient Reflow Temperature 260°C max. temp. 1 min. max. suppression. ©2003 TELEDYNE RELAYS • Precious metal alloy contact material with gold plating assures excellent high current and dry circuit switching capabilities.
