KZM Aluminum Electrolytic Capacitors Chemi-Con KZM Aluminum Electrolytic Capacitors offer longer life than Chemi-Con's KZH Series, which can endure 6000 to 10,000 hours at +105°C. KZM Aluminum Electrolytic Capacitors are radial leaded and have an innovative electrolyte that minimizes ESR. The series offers low impedance, a capacitance range from 27µF to 10,000µF, a voltage range from 6.3V to 50V, and an operating temperature range from -40°C to +105°C.
