High coil resistance reed relays rated up to 3kV
Stephen LawCircuit Protection Electronics Reed relays
PICKERING ELECTRONICS Series 100HV and Series 100HC small Single-in-Line (SIP/SIL) reed relays are rated up to 3kV stand-off voltage and with more than double the coil resistance of previous devices (up to an impressive 6800 Ohms). The varied relay range is suitable for many applications including mixed signal semiconductor testers, high-end cable testers, backplane testers, medical electronics, electric vehicles, solar energy, big physics, in-circuit test equipment and high voltage instrumentation.
Series 100HC high power SIL/SIP 40W reed relays may be used at 3A continuous carry current and even higher levels in pulsed current applications. Devices are suitable for low level or ‘dry’ switching applications, and due to the high coil resistance figures of up to 6000 Ohms they are ideal for low power consumption. This higher coil resistance results in reduced heating, giving a thermal EMF performance less than 10μV.
