3632B222LL Datasheet/PDFFixed Inductors
A fixed inductor is a component that stores energy in the form of magnetic fields and dissipates energy from two terminals, usually through a conductive coil. It is typically used in a variety of electrical components, including transformers, filters, oscillators, and other electronics. The specific type of fixed inductor used in a particular application depends on its characteristics, such as inductance, frequency response, resonance, and saturation. The 3632B222LL is a special type of fixed inductor that features high inductance, low resistance, and a wide range of frequency response. In this article, we will examine the 3632B222LL’s application field and working principle.
Application Field
The 3632B222LL is a low-profile surface-mount fixed inductor, measuring just 0.37 in x 0.27 in, or 9.4mm x 6.9mm. It is designed for use in high-frequency switching power supplies, DC-to-DC converters, Class D amplifiers, and other similar applications. It is particularly well-suited for high-power applications, thanks to its ability to maintain robust inductance even in the presence of high current and voltage peak demands. The 3632B222LL is also ideal for use in a variety of automotive applications, since it can withstand high temperatures and vibration, allowing it to operate reliably in challenging environments.
Working Principle
The working principle of a fixed inductor is essentially the same as that of any other inductor. When current passes through the inductor, it produces a magnetic field that stores energy. This energy is subsequently released when the current is switched off, constituting the so-called back EMF. This back EMF can be enough to cause damage to components downstream, so the 3632B222LL is equipped with built-in protection to reduce the amount of back EMF released. It also utilizes double-shield winding construction to reduce noise and has a high-temperature solder-resistant coating to improve reliability in demanding applications.
Conclusion
The 3632B222LL is a versatile fixed inductor designed for use in numerous applications, from automotive to consumer electronics. Its small size and low resistance make it ideal for high-speed switching operations, and its high inductance and double-shield winding construction help ensure robust performance. Furthermore, its high-temperature solder-resistant coating provides reliability and helps protect against back EMF damage.
