Class I capacitors have a temperature coefficient that is typically fairly linear with temperature. These capacitors have very low electrical losses with a dissipation factor of approximately 0.15%. They undergo no significant aging processes and the capacitance value is nearly independent of the applied voltage. These characteristics allow applications for high Q filters, in resonant circuits and oscillators .
The EIA RS-198 standard codes ceramic class 1 capacitors with a three character code that indicates temperature coefficient. The first letter gives the significant figure of the change in capacitance over temperature (temperature coefficient α) in ppm/K. The second character gives the multiplier of the temperature coefficient. The third letter gives the maximum tolerance from that in ppm/K. All ratings are from -25 to 125 °C:


■Capacitance has linear temperature coefficient
■Capacitance high stability
■Epoxy Coating for 1KV, 2KV, 3KV, 6KV parts (equivalent to UL94V—0 standards)
■Low lost at wide range of frequency
■RoHS Compliance
■Halogen free products are available
