Original Press Release:
DKIH - High Current Choke
Common Mode Chokes for 1- and 3-Phase Applications mount on PCB
Santa Rosa, California, – SCHURTER expands its wide range of current compensated chokes with high current types for PCB mounting.
The new DKIH series are available for single and three phase applications with rated currents from 10 to 50 amperes. Due to its open design, the chokes are light weight and compact, 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 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 arise. It also becomes increasingly challenging to meet EMC requirements with a filter package due to the resulting space constraints; therefore a filter on PCB with discrete components is a good solution. Next, the capacitors and a common mode choke, with asymmetrical effective inductance, are very effective to dampen EMI noise.
The new DKIH-1 series is suitable for single phase AC or DC applications from 10 up to 50 amperes. Light weight and compact, the common mode chokes are easily placed on the PCB with through-hole technology (THT). They are designed and approved according IEC 60938, UL 1283 and CSA 22.2 no. 8.
The voltage rating is 300 VAC (IEC, UL), 250 VAC (CSA) and 425 VDC. Inductance ratings range from 0.30 to 0.90 mH.
The new DKIH-3 series is suitable for three phase AC applications from 10 up to 50 amperes. The common mode chokes are also designed according IEC 60938 and are rated 600 VAC, making them suitable for many applications. Inductance ratings range from 0.08 to 1.10 mH.
The DKIH-1 and -3 have a wide temperature range of -40 to +100°C. They are available with a standard pin out or customer specific pin out. Variations in the winding are also available on request. The DKIH product family is designed for use in applications such as frequency converters for photovoltaic or energy storage, charging stations for electric vehicles, UPS systems and switch mode power supplies.
Pricing starts at just $8.73 each per 100 pieces. Packaging is 20 pieces per box, except for the 10 and 12 A versions of the single phase product which are 40 pieces per box.
