1-phase High Current Choke
1-phase High Current Choke

Schurter is expanding the range of current-compensated chokes with a series for 1-phase high-current applications on printed circuit boards. Coming with a vertical design, the new DKIV-1 series requires a significantly smaller footprint. Compact and lightweight, the chokes are available with ferrite or nanocrystalline cores.

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

Compact and lightweight

The new DKIV-1 series is manufactured for 1-phase applications at rated currents from 10 A to 50 A. Despite the high currents, the vertical choke requires only a small footprint on the PCB. This allows a compact design with high performance. The contacting is made by means of through-hole contacts (THT).

The combination of a vertical choke (DKIV) with a horizontal choke (DKIH) in multistage filters reduces mutual interference of the magnetic fields of the individual chokes.

Performance and approvals

The DKIV-1 current compensated chokes comply with IEC 60938 and with a rated voltage of 300 VAC or 450 VDC, they are suitable for many application. The DKIV-1 series is certified for current ratings from 10 to 50 A, 300 VAC according to IEC and UL and 10 to 50 A, 250 VAC according to CSA. The chokes have ENEC and cURus approvals. The DKIV-1 have been designed for a wide temperature range from -40 °C to +100 °C.
