511-20F

Fixed inductors are among the simplest of electrical components and are used in a range of applications. The 511-20F fixed inductor is a small package component incorporating air core construction technology and design features specifically designed for extreme frequencies. It is ideally suited for switches, converters, and amplifiers.

The 511-20F application field includes high-frequency switching applications such as radio frequency (RF) circuits, power supplies, motor drive controllers, and robotics. It is also used in many general-purpose applications such as audio and video receivers, power amplifiers, and waveform monitors.

This inductor is designed for operation with a maximum operating voltage of 250 volts and is operated over a range of 0-65kHz. It provides an inductance range of 0.30 − 20.00 μH and is a two terminal component with under-the-pad mounting. Due to its relatively smaller size, it is well-suited for use in high-density magnetic applications.

When the 511-20F inductor is energized, the current flows along a wire or coil which then creates a magnetic field. The magnetic field induces a voltage in the coil and this voltage opposes the applied voltage. The ratio of the applied voltage to the induced voltage is called the “inductance” of the inductor.

Inductance is measured in “Henries”, and is equal to the ratio of the applied voltage to the induced current. At lower frequencies, the inductance increases as the frequency increases. However, at higher frequencies the inductance typically decreases due to the increased frequency of the electromagnetic radiation in the air gap of the inductor.

The 511-20F inductor is also designed with a self-resonant frequency, which is the frequency at which the inductance is equal to the capacitance of the inductor. This is usually very close to its rated inductance value, and the self-resonant frequency decreases as the inductance increases. This means that at lower frequencies, the inductor\'s inductance is higher than at higher frequencies.

One of the other main advantages of having a self-resonant frequency is that it allows for better signal separation between input and output signals in complex RF circuits. This helps to improve signal integrity in high-speed applications.

Due to its small size and high inductance, the 511-20F is a great choice for high-frequency switching applications where a wide range of inductance values is needed. It is also able to handle high operating voltages and temperatures, making it suitable for use in a variety of applications.
