Note: NPO and COG are synonymous terms for an industry standard dielectric material used for ceramic capacitors

which provides a very low temperature coefficient of capacitance (±30 ppm per °C) and voltage coefficient of

capacitance (under 0.01% per Volt). It also has a low dissipation factor (0.1% max at 1 MHz for the values of

interest).
