Fixed Inductors have been widely used in electronic circuits for many reasons. They provide a stable, reliable and consistent energy output throughout their life cycle. Commonly known as chokes, fixed inductors are mostly composed of a coil of wire or flat ribbon code with a core material usually made of iron-powder. Inductors are commonly used to provide electrical and magnetic filtering functions, reduce broadband noise, smooth DC power voltages, limit the current in AC circuits, as well as stabilize and protect electrical devices from over-voltage surges.The RCR108DNP-221L fixed inductor is a surface mount device, specifically a power line filter inductor, which is designed for use in DC power supply applications. It is widely used in switching power supplies, telecoms, computer products, industrial applications, audible devices, radio frequency, and acute medical instrument. The inductor is in a small package to save board space, and has a low DC resistance with high inductance. It can handle a maximum current of up to 2.5A at ambient temperatures of up to +125°C. It meets military-grade requirements for dB point specification and has been extensively tested for quality and reliability.The RCR108DNP-221L fixed inductor employs an inductance range of 0.56~100mH, and its high load current and voltage capacity make it suitable for a broad range of DC-DC converters and other power components. It is composed of a ferrite core and a winding of copper wire, and its surface mount design allows for easy installation and automated manufacturing.The fundamental working principle of the RCR108DNP-221L fixed inductor is based on Faraday\'s law of induction, which states that a varying electrical current through a conductor produces a magnetic field around the conductor. When a constant voltage is applied across the inductor, a current will begin to flow. As the current interacts with the magnetic field, an inductance is generated, and the current is prevented from changing unexpectedly. As the applied voltage increases, so does the current flowing through the inductor, thus providing a more stable and consistent voltage level across the device.The RCR108DNP-221L fixed inductor can handle up to 2.5A of current, and its inductance range of 0.56~100mH makes it suitable for a variety of DC-DC and other power applications. It features high electrical and thermal resistance, is low-profile and easily installed, and meets military-grade requirements for dB point specification. Thanks to its design and technology, it provides a reliable and consistent energy output throughout its life cycle.
