where sharp edges in waveforms generate radiated emissions. This common-mode choke will also be used in low-profile, high-current power supplies; DC/DC converters in distributed energy systems; and power converters for solar panels.
To withstand the extreme environments of these applications, the self-shielded device features a compact and robust nanocrystalline core, as well as a reinforced overmolded construction. The SGCM05339 offers high impedance at extended frequencies, supports rated currents up to 14.43 A, and provides a continuous operating temperature range of -55 °C to +130 °C.
Meeting the degassing requirements of ASTM-E595, the device launched today is available with a wide range of certification options, including MIL-PRF-27, Grade 5, Product Level T, Temperature Class S; MIL-STD-981 Family 4, Class S; and EEE-INST-002. The SGCM05339 offers an insulation voltage of 1000 VRMS, a minimum insulation resistance of 10 GΩ at 500 VDC, and can be customized in number of turns, wire gauge, and other parameters to suit specific requirements.
