Converters and filters

SynQor has introduced its MilQor range of DC/DC converters and complementary EMI filters that has been designed specifically for high reliability and manufactured in an AS9100B certified facility in the US. They feature QorSeal packaging that ensures survivability in harsh environments and are compatible with the present industry-standard formats but dissipate only half the heat due to their efficiency levels (>90%).

The range addresses both the 28 and 270 V power systems.

The MilQor converters include single-, dual- and triple-output configurations, with standard output voltages ranging from 1.5 to 30. Output power and current levels are up to 120 W and 40 A. Features include fixed-frequency switching, no opto-isolators, current sharing, remote sense, clock synchronisation, primary- and secondary-side enable, continuous short-circuit protection, input undervoltage lockout and input overvoltage shutdown.

The filters are available with passive components only, or with additional active circuitry that provides surge/spike suppression, soft start in-rush limiting, reverse-polarity protection,holdup capacitor pre-charging, and enable signal pass-through.

They are also available in standard and extended input voltage ranges. All filters provide >80 dB of differential attenuation (and >60 dB of common-mode attenuation) at 500 kHz, and they include stabilising bulk capacitors and damping resistors. All capacitors are X7R ceramics.
