Below is a list of Pulse Transformers manufacturers from Cary, Illinois. Pulse transformers are wide-band devices that are mainly intended for waveform transmission that transmit rectangular electrical pulses; this means that the pulses have fast rise and fall times with a fairly constant amplitude. Pulse transformers are unlike other electric transformers. Typical alternating current (AC) transformers’ magnetic fluxes alternate between negative and positive values, but pulse transformers’ magnetic fluxes do not.
