Fixed InductorsFixed inductors are used to store energy in the form of an electric field in a circuit. Although they come in many shapes and sizes, all inductors are classified according to their inductance value, which indicates the amount of energy a particular inductor can store. One such fixed inductor is the SDR0503-471K.The SDR0503-471K is a radial-lead type, metal-alloy core fixed inductor. Its dimensions are 0.50" x 0.33" and its inductance is 470nH ±20%. Its rated current is 500mA and features a capacitor combination with an operating temperature range of -40°C to +85°C. The SDR0503-471K has a metal-alloy core which provides the device with high temperature stability. The leads are made of tinned copper and come in two lengths: short and long.The SDR0503-471K fixed inductor is mainly used in circuits that require current converters, continuity testing,-velocity measurement, bipolar drive, and DC/DC converters. Specifically, the SDR0503-471K can be used in portable audio devices, tattoo machines, laser diode drivers, motor controls, and switching power supplies.The working principle of the SDR0503-471K is similar to that of other fixed inductors. When a current is applied, the metal-alloy core of the inductor stores magnetic energy, which is then used to oppose the flow of current in the inductor. This opposition is referred to as inductance and is measured in units called Henries (H). The metal-alloy core of the SDR0503-471K gives it a high degree of temperature stability, enabling it to perform reliably in high-temperature environments.Inductors are essential components of many electronic circuits, especially circuits in which energy-efficient operations are desired. The SDR0503-471K is a useful and versatile device that can be used in a variety of circuits ranging from audio amplifiers to power supplies to test and measurement instruments. Its heat-resistant metal-alloy core, generous operating temperature range, and low inductance value make it an ideal choice for a wide range of applications.
