Fixed inductors, or RF inductors, are one of the most popular passive electronic components used in many industrial and consumer applications. The ELC-15E331 is a radial leaded RF inductor designed for high frequency switching power supplies, switching converters, and DC/DC converters. The device features a ferrite magnetic core for superior inductance, high current handling capability, and long-term reliability.

The ELC-15E331 fixed inductor is designed to have a DCR (DC resistance) of 0.3 ohms maximum and inductance of 15mH (15 MillsH) minimum. The inductor operates over a temperature range of -40 to +85C and can withstand high currents up to 8A. It has a beveled lead form factor with a base diameter of 6.3mm and a height of 6.6mm. The device is ideal for mounting on printed circuit boards thanks to its small size and low profile.

The device’s primary application field is switching power supplies and DC/DC converters. The ELC-15E331 can be used to filter high frequency noise in switching power supplies, and works as a choke in DC/DC converters for voltage regulation. The device also has other applications such as in high current loop antennas, RF telecommunication circuits, and more.

The basic working principle of the ELC-15E331 fixed inductor is the same as any other inductor. It works by converting the current changes in the electrical circuit into a changing magnetic field around the inductor. This magnetic field induces a voltage across the inductor due to lenz\'s law. The induced voltage results in an opposing current, limiting the current flow and storing energy in the form of a magnetic field. The inductor then stores and releases energy from the magnetic field according to changes in the current of the electrical circuit.

The ELC-15E331 fixed inductor is a great choice for a variety of applications thanks to its small size and superior inductance. The device has a wide range of applications in power supplies, DC/DC converters, high current loop antennas, and more; and its low DCR and high current rating makes it suitable for high frequency switching power supplies and DC/DC converters. It is a highly reliable and cost-effective device for filtering high frequency noise and improving the AC impedance of power supplies.
