Q: How is a L Filter Built?
Two elements: a feedthrough capacitor from line to ground, and an inductor connected in series with it between the input and output terminals.
The capacitive element can be placed on either the line or load side of the filter, making it either a capacitive or inductive input. Its attenuation increases at 40 dB per decade from its cutoff frequency to at least that frequency where it exhibits a minimum attenuation of 70 dB. It maintains this level at higher frequencies. They are commonly referred to as L filters:
- L1 indicates that the inductive element is on the end with the threaded mounting neck.
- L2 indicates that the capacitive element is on the end with the threaded mounting neck. L-Only Filters or LL are used when the difference between line and load impedance is large.
The inductive element is best placed so that it faces the lower impedance.
