SERIES BROADBAND RF311 HIGH REPEATABILITY TO-5 RELAY RF331 SPDT DC8 GHz SERIES RELAY TYPE DESIGNATION RF311 SPDT RF TO-5 relay RF331 Sensitive, SPDT RF TO-5 relay INTERNAL CONSTRUCTION PERFORMANCE FEATURES UNI-FRAME UPPER The ultraminiature RF311 and RF331 relays are STATIONARY CONTACT designed to provide improved RF signal repeatability over the frequency range. These relays are highly MOVING suitable for use in attenuator and other RF circuits. The CONTACT RF311 and RF331 feature: ARMATURE High repeatability. LOWER Exceptional bandwidth. STATIONARY Metal enclosure for EMI shielding. CONTACT Ground pin option to improve case grounding. High isolation between control and signal paths. Highly resistant to ESD. ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS CONSTRUCTION FEATURES Storage 65C to +125C Temperature (Ambient) The following unique construction features and Operating 55C to +85C manufacturing techniques provide excellent resistance Vibration 10 gs to 500 Hz (General Note 1) to environmental extremes and overall high reliability: Shock 30 gs, (General Note 1) 6ms half sine Uni-frame motor design provides high magnetic efficiency and mechanical rigidity. Enclosure Hermetically sealed Minimum mass components and welded construction RF311 0.089 oz. (2.52g) max. Weight provide maximum resistance to shock and vibration. RF331 0.109 oz. (3.09g) max. Advanced cleaning techniques provide maximum assurance of internal cleanliness. Gold-plated precious metal alloy contacts ensure reliable switching. Hermetically sealed. RoHS compliant. 2007 TELEDYNE RELAYS (800) 284-7007 www.teledynerelays.com RF311/RF331 Page 1 RF311RF331 022007 Q1SERIES RF311 AND RF331 GENERAL ELECTRICAL SPECIFICATIONS ( 25C unless otherwise noted) (Notes 2 & 3) Contact Arrangement 1 Form C (SPDT) Rated Duty Continuous Contact Resistance 0.15 7 max. initial (measured 1/8 q (3.2mm) from header) Resistive: 1A 28V dc Contact Load Ratings (DC) Low level: 10 to 50 A 10 to 50 mV Contact Life Ratings 10,000,000 cycles (typical) at low level RF311: 350 mW typical nominal rated voltage Coil Operating Power RF331: 185 mW typical nominal rated voltage RF311: 4.0 mS max.
