New Product Line Amorphous C-Cores
C-cores from amorphous Fe-based alloys (e. g. METGLAS 2605® SA1) are an interesting alternative for pfc or dc chokes in different converter types. They combine a high saturation flux density with low core losses.
The products are made in China under quality control of our local partner. Starting with selected types of the American AMCC series our offer will be enlarged successively.
Bobbins are offered as well as clamping straps. A brochure with product information and design notes can be downloaded.
New Sample Kit Common Mode Chokes
Vacuumschmelze GmbH & Co. KG (VAC) presents a new sample kit of Common Mode Cokes with nanocrystalline VITROPERM® cores. The kit contains 24 selected chokes from the new UL 1446 standard series for 1, 3 and 4-phase applications, from 4 to 48 A and operational voltages between 300 and 1000 V.
The nanocrystalline cores feature permeabilities in the range from 5000 up to more than 150000 in combination with a saturation flux density of 1.2 T. The chokes offer a pronounced broadband damping characteristic, often allowing a significant reduction of the size of the choke in comparison with standard solutions. Furthermore the chokes offer a high efficiency, low winding capacity and a stable damping in a wide temperature range.
The kits are available for € 200.-/piece.

Review softmagnetic nanocrystalline cores
If you have found us in the infinite space of the www, then you may perhaps be interested in nanocrystalline materials and cores. The following publication reviews the basics and main applications.

Limericks on a German website for electro-technical products?
Why not. It does not hurt, but humor often helps to survive endless days of problem-solving.
It's a short page (because it should not keep you from problem-solving), and it is in German (because our English is not Limerick-proved). However, we are really looking forward in receiving english Limericks for electrical engineers. Give it a try, and we will award you with a small thank you.
The difference between theory and practical experience
Our contribution to the below mentioned UK Magnetic Society seminar is now available as a download - to all who may have problems with low frequency magnetic fields or simply are interested in the subject. For more information mail us or give us a call.
Advanced Materials and their Applications
The UK Magnetic Society has organised a 2-day seminar from Oct., 12th to 13th 2009 covering the subject in the header. The event has taken place in Hanau, Germany (30 minutes from Frankfurt) and has been be sponsored by Vacuumschmelze GmbH & Co. KG. The language was English.
We have participated with a presentation about the theoretical and practical determination of shielding factors and the related challenges with more complex geometries.

DIN-ISO 9001:2008 Upgrade
"Quality is competitiveness"
The DIN ISO certification is certainly no guarantee to survive todays market conditions, however we are convinced that the awareness of the importance of quality is improving our competitiveness.
Therefore it was no question to use the re-auditification to upgrade our Quality System to the latest version DIN ISO 9001:2008. The certificates are available here as Download.
