Advertorials DKIH: common mode chokes for 1- and 3-phase


applications mount on PCB 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 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 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) and 250 VAC (CSA).


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.


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.

New connector series in grid 1,27 mm x 1,27 mm


Electronic assemblies are designed more and more compact. Therefore the used grids of the connectors is becoming a lot smaller. The grid 1.27 mm is increasing steadily in importance.


Company Fischer Elektronik has arranged a new series of double-rowed connectors in grid 1.27 mm x 1.27 mm in this range. As designs we set up connectors in straight version: SLV W 4 055 … up to SLV W 4 130 … in four different contact lengths, in angled design: SLV W 4 KA 036 … and SLV W KA 060 … in two different contact lengths and in SMD version SLV W 4 SMD 048 … and SLV W 4 SMD 073 … in two different contact lengths. The possible number of contacts are available from 4 to 72 for the THT designs and 4 to 40 for the SMD designs.


The contacts are made of a copper-zinc-alloy (CuZn) with a square dimension of 0.4 mm. Surfaces in gold-plated or tin-plated coatings are offered. The temperature resistance of those connectors is basically designed and suited for reflow-soldering process.


Machine compatible packings is more and more getting a requirement for orders, especially for SMD designs. Here the use of the appropriate “Tape and Reel” packings is crystallised.
