Low voltage scanners Medical equipment testers CR Series Multimeters RF transmitters Wafer testers The CR series is our smallest and most versatile The epoxy over-molded ceramic package is very instrument grade reed relay series. The CRF Series has a rugged and has very good low thermal offset voltage flat insertion loss curve from DC up to 7 GHz, attained by capability because of its excellent heat conducting MARKETS keeping the signal path as short as possible and using alumina substrate. Telecommunications, an internal coaxial shield with a consistent 50 Ohm The ceramic substrate has leadless gold plated pads Test & Measurement impedance path. Not only is it excellent with RF signals, making it ideal for surface mounting with no worry of but is also great for digital signals where the skew rates lead skewing or coplanarity issues. or effects on the rise time of fast digital pulses is less than 40 picoseconds through the relay.

SIL High Voltage/High Current Series continued... The CR series is only 3.4 mm high, making it ideal for The relays can dielectrically hold off up to 4000 volts very low profile environments. Because there is an across the contacts as well as between contacts and internal magnetic shield, the relays can be stacked very coil. The relays have standard internal magnetic close together without having to deal with magnetic shields for close stacking matrices. coupling effects between relays. This is the case whether you are designing a two dimensional or three dimensional MS RF Series relay matrix. A BGA option is offered for additional PCB The low cost MS series is a mini SIL principally attach methods. designed for large, closely stacked matrices typically used in functional PCB test systems. These relays SIL RF Series have a standard internal magnetic shield to support The SIL RF Series is configured in a standard SIL the close stacking and avoid any magnetic through-hole package with UL certification. Its internal interference between relays. coaxial shield offers a consistent 50 Ohm impedance path for excellent RF characteristics at an economical cost. Because of their relatively small size and short signal The insertion loss is flat from DC to 1.5 GHz. path, the relays are capable of carrying signals up to 1 GHz by grounding the start wire of the coil. MS relays The SIL RF Series is capable of switching up to 15 watts are also capable of switching DC up to 10 Watts with and voltages up to 200 Volts while providing over 1500 voltages up to 200 volts. One amp of current can be Volts isolation, switch to coil. The contacts can switch up switched with carry currents as high as 2 amps. to 1.0 amp while maintaining a consistent 100 milli-ohm on state resistance. Since it is in a standard SIL Summary package, its foot print is compatible with other sources. The specification chart below summarizes the primary Built-in diode suppression is another option. parameters, while detailed specifications can be downloaded directly from our website: SIL High Voltage/High Current Series www.meder.com The SIL High Voltage/High Current Series was designed primarily for use in automatic test systems, testing high power MOS-FETs. These rugged semi conductors have very high initial peak current capability. Having a reed relay that can carry high current pulses for hundreds of millions of operations is a critical requirement. This series can switch up to 1000 volts and carry up to 5 amps for up to 50 milli-second at a consistent repetition rate.
