Pulse transformers and inductors

Based on toroidal magnetic cores LLC "Yudzhen" manufactures pulse transformers and inductors with inside diameter of over 6.5mm after winding with a wire of a diameter up to 1mm.

Pulse transformers are applied in high-frequency switch mode power supplies. They are distinguished by lower weight, smaller dimensions and lower cost price compared with conventional low-frequency power supplies. Inductors are designed both for protection of power supplies from induced high-frequency signals, and for avoiding electromagnetic interference in mains supply. At low frequencies they are used in supply circuits filters and typically have a metal or ferrite core.

Chokes on toroidal magnetic circuits are an inductor wound on a metal or ferrite toroidal magnetic circuit, which has a high resistance to alternating currents and low resistance to direct currents. The chokes are connected in series in the circuit and are designed to filter or limit the current in the high-frequency circuit.

Chokes on toroidal magnetic circuits are often used both to protect power supplies from the ingress of induced high-frequency signals into them, and to avoid clogging the supply network with electromagnetic interference. At low frequencies, it is used in power supply filters and usually has a metal or ferrite core.

The main purpose of the choke is to protect against high frequency signals.
