Lumped element filters are passive filters made with inductors (Ls), capacitors (Cs), and resistors (Rs) to meet specific filtering needs. They use simple L-C resonators to create poles and zeros in the frequency response, allowing tight control over the filter's performance. These filters are compact, customizable, and can withstand harsh conditions. They can be designed as lowpass, highpass, bandpass, or band-reject filters. Their frequency ranges span from 10 MHz to 22 GHz, making them versatile for various applications.

Capacitors are fundamental components in both analog and digital electronic circuits. These passive components play an important role in influencing the operational behavior of circuits. The characteristics of a capacitor vary mainly depending on the dielectric material used. The dielectric material determines the capacitance value, energy efficiency, and size of a capacitor. Fixed value capacitors can be broadly categorized into two: polar and non-polar capacitors. Non-polar capacitors include ceramic, film, and paper capacitors.
