Determination of the Ni80Fe20 thin film smoothness through the capasitance of film in the low pass R-C filter device. Capacitive properties of Ni80Fe20 thin film as result of dc sputerring on the various deposition field (Bdep) from 0 up to 600 G was reached, The aim of the research is to determine the smoothness of film with investigating the capacitance due to film porosities and the performance of film as low pass filter. Device constitue of the resistor R=769.9 ohm serially connected with a film. Device was supplied with AC voltage from AFG. Investigating the capcititve properties was done on the 100 kHz frequency, while investigating the cutt-pff frequency was done in the range of 100 up to 1000 kHz. The output and input voltage were investigatd through oscilloscope. From investigating the capacitive properties show that all samples display capacitive properties. The lowest capacitance according to the sample resulted from deposition on th Bdep of 300 G that is 0.09 pF, which is show the smoothest film compared with others. It is cab filter the frequencies up to 253.5 Hz.
