Teledyne Relays Announces New SRF300/SRF303 DPDT Relay Series
New Non-Latching SRF300/SRF303 Relay with Signal Integrity Performance Measured up to 18Gbps

Hawthorne, CA, April 2013: Teledyne Relays introduces the SRF300/SRF303 family!
The ultraminiature SRF300 and SRF303 relays are designed to provide a practical surface-mount solution with improved RF signal repeatability over the frequency range. The SRF300 and SRF303 extend performance advantages over similar RF devices that simply offer formed leads for surface mounting. These relays are engineered for use in RF attenuator, RF switch matrices, ATE and other applications that require dependable high frequency signal fidelity and performance.

The SRF300 and SRF303 feature: high repeatability, broader bandwidth, metal enclosure for EMI shielding, high isolation between control and signal paths and high resistance to ESD.

The Series SRF300D/SRF303D and SRF300DD/SRF303DD relays have internal discrete silicon diodes for coil suppression and polarity reversal protection. This hybrid package reduces required PC board floor space by reducing the number of external components needed to drive the relay. The SRF300/SRF303 is available in the SRF300D/SRF303D model with an internal diode for coil transient suppression and SRF300DD/SRF303DD with internal diodes for coil transient suppression and polarity reversal protection.

The SRF300/303 Series measures .370 x .340 x .335 inches (9.4, 8.64, 8.51 cm) weighs .1 ounce (2.9g).
