The HRK CD110 series is a standard plug-in type aluminum electrolytic capacitor designed for general-purpose applications. It features a black sleeve with white lettering, a rated capacitance of 33uF, and a rated voltage of 400V. With a wide operating temperature range of -40 to +105 and a long-life expectancy of 2,000 hours at 105, these capacitors offer reliable performance. They are suitable for applications requiring stable capacitance and low leakage current.
