K42U-2 250 V 0.47 μF

K42U-2 metal-paper capacitors of constant capacitance. Sealed, in a cylindrical metal case with axial leads for surface mounting. Intended for operation in DC, AC, pulsating current circuits and in pulse modes. Available in three versions depending on the shape of the petal leads. Manufactured for moderate and cold climates [UHL5.1]

Explanation of the abbreviated symbol of a paper capacitor: K42U-2 250 V 0.47 μF K is a letter denoting the subclass of capacitors, where K is a constant capacitance capacitor; 42 – a number, indicates a group of capacitors, where 42 are metallized paper; U – a letter, indicates the functional purpose of the capacitor, where U – for operation in DC and AC circuits and in pulse mode; 2 – a number, determines the serial number of the capacitor design development; 250 V – designation of the nominal voltage of the capacitor in volts; 0.47 μF – designation of the nominal capacitance of the capacitor in
