KMS Aluminum Electrolytic Capacitors Chemi-Con KMS Aluminum Electrolytic Capacitors are large capacitance capacitors designed for solar power generation. These snap-in capacitors have been downsized and offer an operating temperature range of up to +105°C. Chemi-Con KMS Capacitors feature a capacitance range from 47µF to 3300µF, a rated voltage range from 160V to 500V, and 3000 hours of endurance at +105°C with higher ripple current than the KMM series.
