Fixed Inductors

Inductors are passive devices used in electrical and electronic circuits. They provide inductance or opposition to the changing current flow, allowing voltage to rise or fall gradually and slowly. Fixed inductors are devices that use a coil of wire or other conductors to produce a fixed inductance in a circuit. In the electronic industry, one of the most popular fixed inductors is the SD12-221-R.The SD12-221-R is a through-hole leaded, shielded surface mount inductor that is widely used in many applications. It is designed for use in general-purpose RF, communications and EMI applications. It is available in four sizes and has an inductance range from 0.1µH to 1.0µH with a tolerance range of +20%/-20%. It also has a rated current of 1.5A.The SD12-221-R is a very low-profile inductor that is ideal for use in narrow spaces. Its compact size makes it perfect for use in portable power systems, mobile phones, PDAs, portable navigation systems, and other handheld devices. Its shielded core makes it more resistant to interference from external sources.The SD12-221-R has excellent efficiency and heat dissipation. Its high-quality core ensures low resistance and magnetic saturation. Its wide inductance range makes it ideal for use in high frequency, high current applications. The SD12-221-R also has wide frequency range and excellent Q-factor for signal clarity and accurate response.The working principle of the SD12-221-R is based on Faraday’s law. When a current flows through the winding, it produces a magnetic field, which in turn produces an opposing voltage. This is the inductance principle of the SD12-221-R.The SD12-221-R is used in a variety of applications. It can be used as an output filter for switching power supplies, a choke for harmonic reduction in power factor correction circuits, and a resonance filter in communication systems.The SD12-221-R can also be used in automotive and home appliances, such as HVAC equipment, washing machines, dishwashers, and more. It can be used to make a stabilizing current flow in the power circuit and stabilize the voltage output.The SD12-221-R is a versatile and reliable inductor that can be used in many applications. Its wide inductance range, excellent heat dissipation, and low-profile design make it an ideal choice for many applications. It is also a great choice for high-frequency, high-current applications.
