NPO capacitors have a linear temperature coefficient over the range of -55° C to +125° C, low loss, and have a negligible change of electrical properties with time, voltage, and frequency. The lower picofarad capacitors are typically NPO (COG) and have a better Tolerance than 5%.
X7R dielectric capacitors have a non-linear temperature coefficient over the range of -55° C to +125° C, low loss, and have a good aging rating. The higher picofarad caps are typically rated as X7R . This kit includes only NPO dielectric capacitors. You get the following:
