Table 1. EIA Designations for Class I Dielectrics The most common Class I dielectric for chip capacitors is the C0G designation (emphasized with red text in Table 1) and is also known as NP0 (negative-positive-zero) in the U.S. military (MIL) specification for its flat temperature coefficient.
Class I dielectrics have a linear temperature coefficient of capacitance (TCC). The temperature coefficient of C0G is 0 ± 30 ppm/°C for the temperature range of -55ºC to +125ºC while that of U2J is -750±120ppm/°C for the same temperature range. In addition, Class I capacitors have high insulation resistance.
Dielectrics enable the capacitor to have much greater capacitance, which is useful for storing charge for energy applications or tuning its frequency-response behavior in filtering applications. From a practical standpoint, dielectrics prevent capacitor failure via discharge or plate contact.
Class I ceramic capacitor materials include C0G and NP0. These materials offer a higher temperature range and more stable capacitance over the rated temperature range. Class II ceramic capacitors include X5R and X7R, which have a higher temperature coefficient. X5R capacitors have the lowest temperature rating, but offer the lowest cost.
Piezoelectric materials are another class of very useful dielectrics which are used for transducers and sensors. Ferroelectric materials often have very high dielectric constants, making them quite useful for capacitors. Classification of dia, para and ferromagnetic materials.
