Current sense transformers are used to detect and measure current.

Switch mode transformers (switching transformers) are used mainly in switching power supplies and DC-DC converters.

Three phase uninterruptible power supplies (UPS) are devices that operate in conjunction with existing electrical systems to provide power conditioning, back-up protection and distribution for electronic equipment loads.

Power supplies are devices that produce AC or DC power.

Audio microphones are designed for sound reception and recording applications (speech and music).

Impedance matching networks are electrical circuits which, when connected between two networks, match the output impedance of the source (the first network) to the input impedance of the load (the receiving or second network).

RF phase shifters are twin-ported devices that alter the phase of an output signal in response to an external signal.
