Nichicon CK Ultra Low ESR Capacitors

Nichicon
Ultra Low ESR Capacitors
CK Series

The Nichicon CK Series Conductive Polymer Ultra Low ESR Capacitors offer ultra low ESR (≤ to specified value at 100kHz, 20ºC). The CK Series are aluminum solid electrolytic capacitors for SMD with lead-free reflow at 260ºC peak correspondence. The Nichicon CK Series Conductive Polymer Ultra Low ESR Capacitors feature high ripple current, high capacitance (220 to 2200µF) low impedance, an anti-solvent feature, and are ideal for high frequency applications.

*1 ESR should be measured at both of the terminal ends closest where the terminals protrude through the plastic platform.
*2 Conditioning: If any doubt arises, measure the leakage current after the voltage treatment of applying DC rated voltage
continuously to the capacitor for 120 minutes at 105ºC.
