UNI-FRAME
SERIES
The ultraminiature RF311 and RF331 relays are
designed to provide improved RF signal repeatability
over the frequency range. These relays are highly
suitable for use in attenuator and other RF circuits. The
RF311 and RF331 feature:
• High repeatability.
• Exceptional bandwidth.
• Metal enclosure for EMI shielding.
• Ground pin option to improve case grounding.
• High isolation between control and signal paths.
• Highly resistant to ESD.
CONSTRUCTION FEATURES
The following unique construction features and
manufacturing techniques provide excellent resistance
to environmental extremes and overall high reliability:
• Uni-frame motor design provides high magnetic
efficiency and mechanical rigidity.
• Minimum mass components and welded construction
provide maximum resistance to shock and vibration.
• Advanced cleaning techniques provide maximum
assurance of internal cleanliness.
• Gold-plated precious metal alloy contacts ensure
reliable switching.
• Hermetically sealed.
• Solderable leads.

GENERAL NOTES
1.Relay contacts will exhibit no chatter in excess of 10 μsec or transfer in excess of 1 μsec.
2.“Typical” characteristics are based on available data and are best estimates. No ongoing verification tests are performed.
3.Unless otherwise specified, parameters are initial values.
4.Leads are 0.75″ standard. To order 0.187″ leads, add P to the base part number.
