Fixed InductorsThe SPD74R-122M is designed to perform the duties of a fixed inductor. A fixed inductor is an electronic component, also known as a tank circuit, that consists of an inductor and a capacitor connected in parallel. The main purpose of an inductor is to block the flow of direct current, but allow alternating current to pass. The inductor\'s response to an alternating current gives the inducomponentscorporationtor its own unique characteristics or reactance.The SPD74R-122M has a resistance rating of 22 mOhms minimum or 45 mOhms maximum depending on the application. The inductance range is 1 to 10 microhenries. The rated current is approximate 10 to 20 amps with maximum temperature up to 125°C.In order to better understand the working principle of a fixed inductor, it is important to understand how a capacitor and an inductor work together. The capacitor and inductor effectively create a frequency-dependent resistance. As the frequency increases, the inductor accumulates a large amount of energy and starts to oppose the current, causing the inductive reactance to rise. This in turn causes the overall resistance of the circuit to increase with frequency, which limits the current that can pass through the inductor.The capacitance of the circuit also affects the electron flow. As the frequency passes through the capacitor, the capacitive reactance drops, reducing the total resistance of the circuit. This is why the SPD74R-122M is best suited for higher frequency communications.The SPD74R-122M is designed to perform a variety of applications, including electronically controlled motors, power converters, and switching power supplies. This inductor works particularly well for high-voltage applications due to its high maximum temperature rating and high current rating.The SPD74R-122M also offers low losses at high frequencies. Its low DC resistance prevents voltage drops and ensures reliable operation under high frequency loads. The low reactance and DC resistance make it an ideal choice for power supplies and switch-mode rectifier bridges.The SPD74R-122M is a highly versatile fixed inductor trusted in a variety of applications. Its resistance range, current rating, and temperature rating provide ample protection for high-voltage applications. Its low losses at high frequencies make it a great choice for power supplies and switch-mode rectifier bridges.
