U range of Ultra-low ESR Capacitors ESR Ultra-low ESR U Range Electrical Details The Ultra-low ESR U range offers a very stable, High Q material system Capacitance Range 0.1pF to 1.0nF that provides excellent low loss performance in systems below 3GHz. Temperature Coefficient of Capacitance (TCC) 0 30ppm/C (C0G) Optimised for lowest possible ESR, this range of high frequency capacitors is suitable for many applications where economical, high performance is Q factor >2000 1MHz required.
