1-Phase High Current Choke in Vertical Design
• Small footprint on the printed circuit board
• Open design optimizes heat dissipation
• Compact and lightweight
• Nanocrystalline or ferrite ring cores
Schurter expands its range of current-compensated chokes for printed circuit board mounting, to include a series for 1-phase high-current applications. Due to the vertical design, the new DKIV-1 series sports a significantly smaller footprint. The chokes are available with a ferrite or nanocrystalline core for rated currents from 10 A to 50 A. The open design makes the chokes particularly compact and lightweight.
Like all other aspects of electronic design, the power circuit is oftentimes built today using discrete components on printed circuit boards. With the trend toward integrating components, to achieve smaller and smaller form factors, thermal problems and high current 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 effective asymmetrical common mode choke, together with capacitors mounted on the PCB, is a better solution
Compact and Lightweight
The new DKIV-1 series is designed for 1-phase applications at rated currents from 10 A to 50 A. Even at the max. rating, the vertical choke requires only a small footprint on the PCB, thus allowing a compact design with high performance. The compact and lightweight current-compensated chokes are throughhole mounted. They are ideal 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.
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 almost any 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 series has been designed for a wide temperature range of -40 °C to +100 °C.
