NPO Capacitor

NP0 is the most commonly used monolithic ceramic capacitor with temperature compensation characteristics. Its filling medium is composed of rubidium, samarium, and some other rare oxides.

NP0 capacitor is one of the capacitors with the most stable capacitance and dielectric loss. The capacity changes from 0 ± 30 ppm/℃ at temperatures ranging from - 55 ℃ to 125 ℃, and the change in capacitance with frequency is less than ± 0.3 Δ C。 The drift or hysteresis of the NP0 capacitor is less than ± 0.05%, which is negligible for thin film capacitors larger than ± 2%. The typical change in capacity relative to service life is less than ± 0.1%. NP0 capacitors have different characteristics of capacitance and dielectric loss varying with frequency depending on the packaging type. Larger package sizes have better frequency characteristics than smaller package sizes. The following table shows the selectable capacity ranges for NP0 capacitors.

Package DC=50V DC=100V

0805 0.5---1000pF 0.5---820pF

1206 0.5---1200pF 0.5---1800pF

1210 560---5600pF 560---2700pF

2225 1000pF---0.033 μ F 1000pF---0.018 μ F

NP0 capacitors are suitable for slot capacitors in oscillators, resonators, and coupling capacitors in high-frequency circuits
