Fixed inductors are electrical components designed to provide a specific amount of electrical inductance. The SCRH105R-471 is one such component that is widely used in many applications due to its excellent performance and robust construction. This article will give a brief overview of the SCRH105R-471, along with its application field and working principle.

The SCRH105R-471 is a radial-lead, fixed inductor suitable for automated surface mounting. It is made of an iron powder core with an external tin/lead electroplating for superior adhesion to surfaces. The inductor measures 4.7mH and has a Q-value of 10.7 at 1kHz. The operating temperature range is between -40°C and 85°C, and the operating frequency range between 10kHz and 1MHz.

The SCRH105R-471 is mainly used in digital circuits where higher switching frequencies require stable and high-quality inductance in order to reduce the effect of capacitive coupling. For example, it can be used to smooth the power signal and reduce ripple noise in voltage regulation circuits such as buck converters, DC/DC converters, and boost converters. It can also be used in audio filtering circuits, motor control circuits, communication circuits, and other electronic circuits.

The working principle of the SCRH105R-471 is based on Faraday\'s law of electromagnetic induction. When an electric current flows through the inductor, it produces an electromagnetic field around it. This field inductively couples with an adjacent circuit, creating a self-induced voltage in the circuit. This voltage opposes the change of current flowing through the inductor, thus providing the desired inductance.

The SCRH105R-471 is a highly reliable and cost-effective component that is suitable for a wide range of applications. It can provide stable and high-quality inductance, and its small size allows it to be easily integrated into many electronic circuits. This makes it an ideal solution for many demanding applications.
