2010-09-03 Optoisolators offer 1kV isolation in TX, TXV, COTS
OPTEK Technology has developed a series of high-reliability, optically coupled isolators that provide up to 1kV electrical isolation with a high current transfer ratio. These isolators providing military electronics design engineers with the ability to optically isolate sensitive circuit elements. Designated the 4N2x and 4N4x Series, the optically coupled isolators come in hermetically sealed metal packages, either surface mount carriers, or through-hole metal cans, which are processed to TX and TXV MIL-PRF-19500/486 and /548 specifications. COTS-level devices are also available.
