GENERAL INFORMATION
“U” Series capacitors are C0G (NP0) chip capacitors spe -
cially designed for “Ultra” low ESR for applications in the
communications market. Max ESR and effective capacitance
are met on each value producing lot to lot uniformity.
Sizes available are EIA chip sizes 0603, 0805, and 1210.
