RNL Electrolytic Capacitors Nichicon RNL Electrolytic Capacitors are conductive polymer aluminum solid electrolytic capacitors that feature a low ESR less than or equal to the specified value at 100kHz at +20°C with 820 to 2200µF capacitance and a high ripple current. These large-sized capacitors offer a load life of 2000 hours at +105°C. Compliant to RoHS directive 2011/65/EU, these capacitors have a radial-lead type with lead-free flow soldering condition correspondence.
