Series RF424/GRF424/SGRF424 Electromechanical <strong>Relays</strong><br />
The Series RF424/GRF424/SGRF424 relay is an ultraminiature, hermetically sealed, magnetic-latching relay<br />
featuring low intercontact capacitance for exceptional RF performance from DC-8 GHz. Its low profi le and<br />
small size make it ideal for applications where extreme packaging density and/or close PC board spacing are<br />
required. The RF424 Series features a unique ground shield that isolates and shields each lead to ensure<br />
excellent contact-to-contact and pole-to-pole isolation. This ground shield provides a ground interface that<br />
results in improved high-frequency performance as well as parametric repeatability.<br />
• Excellent Signal integrity up to 12Gbps<br />
• Hermetically Sealed<br />
• High Resistance to ESD<br />
• Metal Enclosure for EMI shielding<br />
• High Repeatability<br />
• Broader bandwidth<br />
• Through-hole or surface-mount<br />
