Capacitors МБГО-1, МБГО-2 – metallized paper sealed single-layer capacitors, of constant capacity, accumulate a charge from 0.25 μF to 30 μF at a voltage of 160V to 630V. The capacity tolerance is ±10% and ±20%. Capacitors are designed for operation at temperatures from -60°С to +60°С. The loss angle tangent does not exceed 0.025. Conclusions – petal, for soldering. Mounting type – hinged. The МБГО-2 condenser differs from the MBGO-1 condenser by the presence of fastening elements on the body.

The advantages of МБГО capacitors are that they have good capacitance and rated voltage at small sizes, a long service life and the ability to recover after breakdown – when short-circuited at certain points of the winding, the short-circuit current melts and partially evaporates thin metal in the breakdown zone, as a result whereby the layers of the winding become insulated from each other.

The disadvantage of capacitors is the low insulation resistance, and therefore the high leakage current. It is undesirable to use these capacitors with a rated voltage close to the circuit voltage.МБГО capacitors are used mainly at low frequencies as blocking and filtering ones, and are more often used in tube amplifiers, audio amplifiers, low-frequency speakers, power filters, for starting asynchronous motors, compressors, pumps.
