EI-33 Bobbin High Frequency EI power EI28 Transformer Coil

Product features 1— High efficiency, high quality materials. 2— Low working temperature and long service life. 3— Good insulation and high resistance to electric power. 4— Good anti-interference performance and high reliability. 5— Low energy consumption and high dc superposition. The working principle of Transformer is to transform ac voltage, current and impedance of the device, when the primary zhongtong have alternating current coil, iron core (or core) to produce ac magnetic flux, induced in the secondary coil voltage (or current). A transformer consists of an iron core (or a magnet) and a coil. The coil has two or more windings, of which the winding is called a primary coil and the rest is called a secondary coil.
