B84143Q0004R229 application field and working principle

B84143Q0004R229 is a part of high frequency transformer core components series of the EPCOS company, which is short for clamped separable magnetic core accessories. This product is characterized by low power loss, high switching frequency, small size, light weight, low price and other advantages. It is widely used in power factor compensation, electronic ballasts, resonant inverters, high frequency harmonic filters and other occasions.

The working principle of B84143Q0004R229 is to rely on a specific core shape and cross section of the core for inductance and capacitance. According to the principle of electromagnetic induction, when the current flows through the winding outside the core, a real magnetic field is generated, and the magnetic flux is transmitted to other parts of the windings, producing induced electromotive force. The magnitude of the electromotive force is determined by the A·turns/meter factor, the conductivity, the number of turns of the winding, and the rate of change of the magnetic field.

The EPCOS company\'s B84143Q0004R229 core has clamping feet structure and symmetrical pole structure, as well as high magnetic field strength, provides a reasonable price. Therefore, it can be widely used in high frequency applications, such as professional audio equipment, automotive electronics, mobile phones and other electronic products.

The B84143Q0004R229 core has a clamping type structure and the core is composed of two parts. The first part is the fixing footed part. The foot surface is concave and convex, and the convex part can be used to clamp the main body to fix it. The second part is the inner core rod of the core. The part which is not cut off is composed of two U-shaped iron cores. The entire core body does not need any additional fixing device, so it is more convenient to use and replace.
