SCHURTER DKIV-1 Series high-current chokes

SCHURTER’s current-compensated chokes for printed circuit board mounting now come in a vertical design, with the DKIV-1 Series designed to support one-phase high-current applications. The vertical design translates to a small footprint, and the chokes are available in ferrite or nanocrystalline core for rated currents from 10 to 50 A.

Like all other aspects of electronic design, the power circuit is often built using discrete components on printed circuit boards. With the trend towards integrating components and to achieve smaller form factors, thermal problems and high current on the PCB can become a challenge. Traditional block filters might address these challenges, but their larger package size also presents challenges due to the space constraints; therefore, an asymmetrical effective common mode choke and capacitors mounted on the PCB is a better solution.

The through-hole mounted DKIV-1 Series chokes are suitable for use in any application requiring EMC asymmetrical inductance, such as frequency inverter for automation, photovoltaic, energy storage, charging stations for e-vehicles and UPS systems. They are also useful for multistage filter applications where the combination of a vertical choke (DKIV) with a horizontal choke (DKIH) reduces the mutual interference of the magnetic fields of the individual chokes.

The series has a wide temperature range of -40 to +100°C and complies with IEC 60938 with a rated voltage of 300 VAC or 450 VDC. The rated current range of 10 to 50 A is rated 300 VAC according to IEC and UL, and 250 VAC according to CSA. The chokes are also rated 450 VDC and carry ENEC and cURus approvals.
