Transformer Kits are assortments of transformers varying in values and quantities. Transformers facilitate the transfer of energy between circuits by means of a pair of wound coil wires. These kits are distinguished by their type, quantity, and mounting style. The kit types encompass current sense, design for power-over-Ethernet, ferrite cores/rods, DC/DC converter, gate drive, high-frequency current sense, high-frequency gate drive, LAN, and rapid design power transformers.
