GRF300-12

Electromechanical Relay 12VDC 390Ω 1A DPDT 9.52x10.41x8mm SMD Signal Relay

The ultraminiature GRF300 and GRF303 relays are designed to provide a

practical surface-mount solution with improved RF signal repeatability over

the frequency range. GRF300 and GRF303 relays feature a unique ground

shield that isolates and shields each lead to ensure excellent contact-tocontact

and pole-to-pole isolation. The GRF300/GRF303 version with

the improved ground connections can push the performance up into the

10Gbps data rates for digital signal integrity applications. This ground

shield provides a ground interface that results in improved high-frequency

performance as well as parametric repeatability. The GRF300 and GRF303

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 GRF300 and GRF303 feature:

* High repeatability

* Broader bandwidth

* Metal enclosure for EMI shielding

* High isolation between control and signal paths

* High resistance to ESD

The following unique construction features and manufacturing techniques

provide excellent robustness to environmental extremes and overall high

reliability:

* Uniframe 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
