Heynen works for innovators.



From our headquarters in Barcelona, Spain, PRAX’s Sales Team and R&D Engineers advise and work closely with our customers and partners around the world in numerous markets such as Electro-mobility, Healthcare, Renewable Energies and Automotive and many more.

Custom as Standard

Within Prax magnetic components subcategories, our default way of co-operation with our customers’ R&D teams is to offer customized designs that are optimized to the specific requirements of every application.


Common Mode Chokesprax common mode chokes.jpg
Common noise filtering chokes. For a discrete component EMC filtering approach, Prax offers a wide range of CMCs in any format and with world-class materials (soft ferrite, nanocrystaline).

Current Transformersprax current transformers.png
AC current measuring magnetic components for low and high frequency applications. Different material grades allow either high accuracy for critical low frequency metering applications or consumption control in high frequency (SMPS).

prax emc filters.pngEMC Filters
EMC filtering solutions in single-phase and three-phase for various industrial and renewable energy applications.

prax input and output chokes.pngInput and Output Chokes
Mid-power range chokes, for various high frequency switching applications. Copper foil, flat and round wire, combined with several magnetic materials (soft ferrite, Sendust, iron powder, amorphous) and multiple formats (E-cores, C-cores, toroidal) allow Prax to meet virtually any customer requirement.

prax planar transformers.pngPlanar Transformers
If low profile, high efficiency and mechanical reliability are a must for customer final application, planar transformers are the optimal solution for high frequency converters.
Combinations of specially shaped soft ferrite cores with multilayer PCBs and copper tracks make a very compact component in a high power density solution.

prax power inductors.pngPower Inductors
Standard power inductors are proven to have limitations for new high current demanding applications. Prax advanced high current power inductors combine special materials and shapes with flat wire helical winding for a very compact and efficient design.

prax pulse transformers.pngPulse Transformers
Design and manufacturing of Pulse and Gate Drive transformers for ransmitting a control signal assuring isolations between low and high oltage circuits.

prax smps transformers.pngSMPS Transformers
Switch-mode power supply main transformers requirements depend on power range, topology, isolation and frequency. Therefore, a wide range of materials, formats and winding technologies are available. Our aim is to optimize size, efficiency and cost.
Designs available for topologies such as flyback, forward, push-pull, half-bridge, full-bridge and advanced resonant topologies.
