Coil Resistance = 850Ω Contact Resistance = 150 mΩ Contact Configuration = DPDT Coil Voltage = 12V dc
장착형태 = PCB Mount Latching = Yes Contact Voltage = 12V dc Coil Power = 200mW Switching Voltage = 28V dc RF300 and RF303 are through hole mount, GRF303 is a surface mount TO-5 relay. TO-5 RF Relay - RF300 and RF303/GRF303
시리즈. The TO-5 RF300 repeatable RF relay, along with the RF303 and GRF303 sensitive repeatable RF relays are ultra-miniature, hermetically sealed with DPDT contact configurations designed to provide improved RF signal repeatability over the frequency range with excellent signal integrity up to 10Gbps. The through hole mount RF303 (stock numbers ; 758-2521 758-2521 and ; 758-2518 758-2518 ) and the surface mount GRF303 (stock numbers ; 758-2483 758-2483 and ; 758-2489 758-2489 ) are sensitive coil versions of the through hole mount RF300 (stock numbers ; 399-9436 399-9436 and ; 399-9442 399-9442 ), they have twice the coil resistance of the standard version so require half the power to operate. The RF300 ( ; 399-9436 399-9436 and ; 399-9442 399-9442 ) has a 6.99mm profile height, the RF303 ( ; 758-2521 758-2521 and ; 758-2518 758-2518 ) has a 9.78mm profile and the GRF303 ( ; 758-2483 758-2483 and ; 758-2489 758-2489 ) has a 10.6mm profile height. The surface mount GRF303 TO-5 relays feature a unique ground shield that isolates and shields each lead to ensure excellent contact-to-contact and pole- to-pole isolation. This ground shield provides a ground interface that results in improved high frequency performance as well as parametric repeatability. These TO-5 relays are designed for use in RF attenuator switching, wireless LAN and many other applications that require dependable high performance in which high speed signals must be transferred. Broad bandwidth, excellent signal integrity up to 10Gbps Hermetically sealed Gold plated contacts Metal enclosure for EMI shielding with high resistance to ESD High isolation between control and signal paths Excellent resistance to shock and vibration High reliability and excellent resistance to environmental extremes Uni-frame design provides high magnetic efficiency and mechanical rigidity
