Inductive Components from SMP - Expanded Performance Range


Graben-Neudorf, Germany - SMP Sintermetalle Prometheus GmbH Co KG (SMP), German manufacturer of soft-magnetic materials and inductive components, has expanded the performance range of its products. The range of inductive components is designed for currents up to 3000 A and frequencies up to 500 kHz, which can be increased to as much as 2 MHz in special applications. SMP uses powder composite materials that have been developed and manufactured entirely in-house and feature lower eddy current and magnetic reversal losses.



The inductive components of the medium-size, family-owned business are noted for their low loss balances, optimal EMC properties, quiet running and compact, lightweight design. They are also maintenance-free. The three-dimensional isotropy of the materials enables compact, lightweight structures, because the magnetic circuits are minimized. This also lowers the magnetic field strength, and the quantity of winding material used can be significantly reduced. Special, magnetorestriction-free materials ensure that components run very quietly. These materials, which are developed and produced according to individual customer specifications, have a high saturation induction, up to 2 Tesla. And the oscillation behavior of the choke can be adjusted specifically by using certain materials or appropriate, magnetically coupled designs with multiple coils.



Depending on their application, the components are designed either as single-conductor chokes for high-current applications, individual chokes, choke modules or LC filters. They can be manufactured with dimensions ranging from 19 mm to 300 mm, weighing from 0.05 kg to 130 kg, and up to temperature class H (up to 180°C). Protection classes up to IP66 are available according to the intended application. All components are RoHS and REACH compliant, and CE- and EAC certified. The materials used are UL listed. SMP has its own, UL approved insulation system and in-house capability to issue UL certification up to 1000 A and 1000 V; for higher currents and voltages, certification is carried out externally.



SMP's inductive components are used in industrial applications in power electronics, automation and signal processing, in drive engineering applications including railway technology, electromobility, maritime and medical engineering, for renewable energies as well as for conventional energies, and in the aerospace industry.



SMP develops and manufactures all the materials in-house according to customer specifications. SMP also expanded its production and development facility to include an injection molding department, so that it can design and manufacture customized insulation systems. Almost 100 percent of the products are custom-made. Consequently, SMP can offer outstanding manufacturing depth, starting with the selection of raw materials and continuing through the production of powder composite materials to the finished end product. Over 50 percent of the products are exported to destinations all over the world.

Company information:

SMP Sintermetalle Prometheus GmbH Co KG develops and manufactures inductive components and magnetically soft materials, cores and mouldings. Based in Graben-Neudorf near Karlsruhe, Germany, the company was founded in 1982 by Vasilios Gemenetzis and today employs about 150 people. Research and development have been key aspects of the company’s philosophy ever since its foundation. SMP’s product range includes low-loss inductive custom components based on in-house-developed powder composites, such as filter, commutating, step-up converter, power recovery and single-conductor chokes. Many of its products are used in the railway industry. The market for inverters for photovoltaic systems that feed solar energy into the electricity grid and for converters for wind turbines is also experiencing strong growth. SMP has become one of the key global suppliers of magnetically soft materials for industrial applications, serving customers throughout the world.
