The KPAL03F433J is an aluminum-polypropylene-paper capacitor manufactured by Miflex. It has a capacitance of 0.33uF and is rated for 250VDC. It has a 5% tolerance on capacitance. This capacitor is suitable for a variety of applications, such as power supplies, filters, and general stepper motor controls. It is a non-polarized capacitor, meaning it does not have anode and cathode leads, and therefore is not affected by AC current flow in either direction. The aluminum-polypropylene-paper construction provides excellent electrical properties, such as low ESR, high insulation resistance, and high frequency stability. This capacitor is RoHS-compliant and is UL recognized.
