Fixed Inductors

LAP02KR121K

Fixed Inductors are a type of component used to store energy in a magnetic field. A common type of fixed inductor is the LAP02KR121K, which is a high-quality, low-profile surface mounted device designed for use in power supplies. It has a wide range of applications in the areas of data communication, military, medical, home audio, and automotive electronics.The LAP02KR121K is characterized by its small size, high power efficiency, and low insertion loss. The inductor is typically used to produce an inductance of 1.2 µH. The package sizes range from 0402 (imperial size) to 1210 (metric size). With a temperature coefficient of +20 ppm / °C, it is suited for operation in moderately harsh environments. The LAP02KR121K is composed of a ferrite core and an inductive coil. The core is typically comprised of ferrite (which is a type of ceramic material), while the coil is composed of a high-purity copper foil. The combination of these materials make the LAP02KR121K widely used in many different applications due to its size and power efficiency.The operation of the LAP02KR121K is based on the principle of electromagnetic induction. Electromagnetic induction occurs when a conducting coil passes through a varying magnetic field. This varying magnetic field induces a voltage in the coil – the larger the changing magnetic field, the larger the induced voltage. The LAP02KR121K is designed to be efficient, with a low leakage inductance of 50 nH. It also has a low DC resistance of 0.85 Ω, which is why it is able to produce a high amount of current when used in its typical applications. Moreover, the LAP02KR121K is designed to be insensitive to temperature fluctuations, meaning that it will still be able to maintain its inductance under a wide range of operating conditions. The LAP02KR121K is most commonly used in power supplies. However, it can also be used in filters for RF and microwave applications, as well as for signal processing and transducer pickups. It can also be used in high frequency switching applications, such as DC-DC converters and inverters. Overall, the LAP02KR121K is a versatile and reliable component, with a wide range of applications in power supplies, filters, transducers, and other high frequency switching applications. Its small size, efficiency, and temperature coefficient make it an ideal choice for these applications.
