Pulse & Datacom Transformers

Pulse transformers and datacom transformers are two types of transformers used in electronic circuits for signal isolation and transmission.

Pulse transformers are used to transmit short-duration electrical pulses between two circuits, while providing electrical isolation between them. They are commonly used in applications such as digital communication, pulse amplifiers, and switching power supplies. Pulse transformers are typically designed to handle high voltage and high-frequency signals, and have a low turns ratio. They are also designed to minimize signal distortion and provide high signal integrity.

Datacom transformers, also known as isolation transformers, are used to provide electrical isolation and impedance matching between two circuits in data communication applications, such as Ethernet and other networking protocols. They are used to eliminate ground loops, reduce electromagnetic interference (EMI), and provide surge protection. Datacom transformers are typically designed to handle low voltage and low-frequency signals, and have a high turns ratio. They are also designed to provide high common-mode rejection and low insertion loss.
