Teledyne PCB Mount RF Relay, 26.5V dc Coil, DPDT

TO-5 RF Relay - 712 Series. Teledyne's TO-5 DPDT relays have become one of the industry standards for low level switching from dry circuit to 1 Amp. Designed for use when close PCB spacing is required, the 712 series have a low coil power dissipation in an ultra-miniature relay package. In addition to the standard types there are the 712 D and 712 TN relays. The 712 D relays have an internal discrete silicon diode which provides coil transient suppression. The 712 TN -5 hybrid relay (stock number ; 758-2449 758-2449 ) has an internal silicon diode and transistor driver. The integrated packaging of the relay with its associated semiconductor devices greatly reduces PCB floor space requirements as well as saving on installation time. With a low inter-contact capacitance and contact circuit losses, the whole range of 712 series TO-5 relays are excellent ultra-miniature RF switches for frequencies well into the UHF spectrum (see datasheet for performance curves). A typical RF application for the TO-5 relay is in hand held radio transceivers, the combined features of good RF performance, small size, low coil power dissipation and high reliability make it a preferred method of Transmit/Receive switching. Hermetically sealed Excellent switching performance from d.c. to 1GHz High resistance to shock and vibration Gold plated contacts Low insertion loss - isolation and intercontact capacitance of 0.4pF Uni-frame design provides high magnetic efficiency and mechanical rigidity High reliability and excellent resistance to environmental extremes Low profile height of 6.99mm
