Coupled Inductors are used in low and high frequency technology. Signals, voltages and currents are converted by these passive components, and they therefore serve to amplify or reduce the respective input variable on the output side. Applications include measurement technology, where the Coupled Inductor acts as a signal transformer. Power transformers are used to match currents and voltages in switching power supplies and other power supply devices to specific quantities.

The manufacturing of Coupled Inductors requires precise winding techniques and high quality materials to achieve optimum performance.

Optimal service from Bürklin Elektronik

In Bürklin Elektronik's online store you will find a wide range of inductors and passive components. You can easily filter the high-quality Coupled Inductors from our well-known manufacturers according to turns, inductance, design, frequency and DC resistance - try it out! If you have any questions, please do not hesitate to contact our experts.
