Paper dielectric

Generally, two aluminum foils are used as the electrodes, and the middle is formed by overlapping and winding the capacitor paper with a thickness of 0.008 to 0.012 mm.

Manufacturing process is simple, cheap, can get a larger capacity

   Usually in the low-frequency circuit, usually can not be used in higher than 3 ~ 4MHz frequency. Oil-immersed capacitor pressure than ordinary paper capacitors, high stability, suitable for high-voltage circuits
