The physical size of the SP1210R-821K is 12.2 x 10.2 x 10.0mm, and it has a lead pitch of 2.5mm.

The SP1210R-821K is designed for a wide range of applications, and is can be used in a variety of situations. It can be used in switching power supplies, motor drive circuits, and DC-to-DC converters. It can also be used in RF circuits, such as amplifiers, filters, or oscillators. In addition, it is well suited for power management circuits, power line filters, and noise suppression. As a general-purpose inductor, the SP1210R-821K is an ideal choice for a broad range of power applications.

SP1210R-821K Working Principle

A fixed inductor is a simple yet important component in any circuit, as it is responsible for storing energy and delivering it to the circuit in reactive form. In the SP1210R-821K, an electrical current is passed through a coil of wire, creating a magnetic field. The inductance of the fixed inductor is determined by the number of coils, the diameter and length of the wire, and the type of material used to construct the wire. The greater the inductance, the more energy is stored in the inductor.

The SP1210R-821K is an example of a low-profile inductor, which is constructed using an air-core. This means that the inductor does not contain any ferromagnetic material, and therefore has a low resistance. This allows the inductor to provide a high level of energy storage capacity, while still having a low profile design. The low profile and high inductance make the SP1210R-821K an ideal choice for a wide range of applications, from power supplies to RF circuits.

Fixed inductors such as the SP1210R-821K are used in a variety of applications, and can provide the necessary inductance needed for most power applications. They have a long-term inductance rating, and can handle a wide range of power ratings and current levels. The SP1210R-821K is designed for a range of uses, and its low profile and high inductance make it an ideal choice for a broad range of applications.
