MK Series Capacitors
Ultra Low ESR, C0G (NP0) Chip Capacitors
GENERAL INFORMATION
Capacitors are C0G (NP0) chip capacitors specially 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 0402, 0603, 0805, and 1210.
