Use red and black test leads to measure the forward and reverse resistances between any two pins of the two-terminal or three-terminal ceramic filter should be ∞

Measure the forward and reverse resistance between any two pins of the two-terminal or three-terminal ceramic filter with red and black test leads respectively. If the measured resistance value is small or 0Ω, it can be determined that the ceramic filter is damaged. ; It should be noted that if the measured forward and reverse resistances are ∞, it cannot be completely determined that the ceramic filter is in good condition, and the substitution method can be used under amateur conditions.

Ceramic filters are divided into two categories: band-stop filters (also known as notch filters) and band-pass filters (also known as filters) according to their amplitude-frequency characteristics.

According to the amplitude-frequency characteristics, it is divided into two categories: band-stop filter (also known as notch filter) and band-pass filter (also known as filter). It is mainly used in circuits such as frequency selection network, intermediate frequency tuning, frequency discrimination and filtering to achieve the purpose of separating currents of different frequencies.

Ceramic filters are made of lead zirconate titanate ceramic material

The ceramic filter is made of lead zirconate titanate ceramic material. This ceramic material is made into a sheet and coated with silver on both sides as electrodes. After being polarized by DC high voltage, it has a piezoelectric effect.
