Schurter DKIH-1 & DKIH-3 Common Mode Suppression Chokes
Schurter DKIH-1 and DKIH-3 Common Mode Suppression Chokes are one-phase or three-phase high current compensated chokes with THT terminals featuring 10A to 50A rated current, 0.08 to 1.1mH rated inductance, and 0Hz to 400Hz power operating frequency. Operating in a 40°C to +100°C temperature range, the DKIH chokes are compact and lightweight with an open design for optimal cooling. Nanocrystalline ring cores offer 8x higher inductance performance than the ferrite core version in the same compact dimensions.
The DKIH-1 components are suitable for single-phase AC or DC applications and are designed/approved according to IEC 60938, UL 1283, and CSA 22.2 No. 8. The voltage rating is 300VAC (IEC, UL), 250VAC (CSA), and 425VDC maximum with an inductance range of 0.15mH to 6.9mH and -30%/+50% tolerance. The DKIH-3 series is suitable for three-phase AC applications and is also designed according to IEC 60938. These devices feature a rated 600VAC maximum with an inductance range of 0.08mH to 10.8mH and -30%/+50% tolerance.
Typical applications for Schurter DKIH-1 and DKIH-3 Common Mode Suppression Chokes include frequency converters, charge stations, switching power supplies, and more.
