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 3,000 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 this 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 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 constructions 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 1,000 A and 1,000 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 energy supply and in the aerospace industry.
