DKIH Series Nanocrystalline Chokes

SCHURTER's DKIH series of current compensated chokes offer high current types for printed circuit boards (PCBs) mounting. They are available with a nanocrystalline ring core, offering 8x higher inductance performance than ferrite core versions in the same compact dimension. The choke family is designed for single- and three-phase applications with rated currents from 10 A to 50 A. Due to their open design, the chokes are lightweight and compact, making them ideally designed to suppress EMI noise caused by power applications on the PCB.

Like all other aspects of electronic design, the power portion is often built using discrete components on PCBs. 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 space constraints; therefore, an asymmetrical effective common mode choke and capacitors mounted on the PCB are better solutions

DKIH-EVB
The DKIH-EVB evaluation boards provide the end-user with a DIY approach to achieve the ideal EMC filter specific to the suppression requirements of user's unique application. The test PCBs are for 1- or 3-phase systems up to 50 A. These evaluation boards accept SCHURTER’s current-compensating DKIH series chokes, which can be set up and easily tested with different L and C values.

DKIH-1
The DKIH-1 series is designed for 1-phase AC or DC applications at a rated current of 10 A to 50 A. The components are designed and approved according to the standards IEC 60938, UL 1283, and CSA 22.2 No. 8. The rated voltages are 300 V_AC (IEC and UL), 250 V_AC (CSA), and 425 V_DC for all variants.

DKIH-3
The DKIH-3 series is suitable for 3-phase applications with a rated current of 10 A to 50 A. The current compensated chokes comply with the standard IEC 60938. With a rated voltage of 600 V_AC, they are suitable for most applications.

DKIH-4
The DKIH-4 series is suitable for 3-phase applications with neutral at nominal currents from 10 A to 40 A. The current compensated chokes comply with the IEC 60938 standard. With a rated voltage of 500 V_AC or 760 V_AC, they are suitable for almost any application.

Compact and lightweight, these current-compensated chokes are easy to insert on the PCB, and the contacting takes place using push-through contacts (THT). The chokes are designed for a wide temperature range from -40°C to +100°C.
