An LC filter combines inductors (L) and capacitors (C) to form low-pass, high-pass, multiplexer, band-pass, or band-reject filtering in radio frequency (RF) and many other applications. One of the main problems with using discrete components is that there are parasitics that can negatively affect the performance of the filter. Enter the coil diameter (form diameter + wire diameter - see diagram). For a particular induc-tor, the impedance increases with frequency and reaches the highest im-pedance point at resonant frequency, fR. Judging by the graph, the nominal impedance is now 1. This calculator is able to calculate the oscillating frequency, coil inductance, and capacitance from the values of 2 input fields. INPUT DATA Relative Dielectric Constant ( ε r ):. Since nearly all physical systems involve considerations such as air resistance, friction, and intermolecular forces where energy in the system is lost to heat or sound, accounting for damping is important in realistic oscillatory systems. 2756R H /f L2 = 0.

It is assumed that the idle Q-factor of C1 and C2 is much higher than that of the L. A fixed regulator is set internally to output a specific voltage, +5V, -12V etc. Typically, the signals we want to pass are around f3dB, so the impedance of the capacitor and the impedance of the resistor will be about the same. If we want to calculate the value of an unknown inductor we use a known Ccal 1000pF capacitor and the value of an unknown inductor. Capacitance: Inductance: Resonant Frequency: Type in the L and C values, selecting the units you wish to use and click.

An element in a DC circuit can be described using only its resistance. Since the inductive reactance is 90 degrees out of phase with the resistance and, therefore, their maximum values occur at different times, vector addition must be used to calculate impedance.
