MKT capacitor with ohm value on case markings
I would like to provide an alternative answer, as to me it makes no sense to have a complex impedance of 0.25J + 200 Ohms printed on a capacitor-looking device, when I know that components that are marked similarly do exist and these have both a capacitor and a resistor combined in one package.
So, most likely that component is a RC snubber component, a device with a capacitor and a resistor in series.
The marking seems to indicate 0.25 units of capacitance, with the units of &quot;uF&quot; for microfarads not printed like on other snubber capacitors. That would indicate 250nF of capacitance.
The J is for 5% capacitor tolerance, many other snubber capacitors have K there for 10% capacitor tolerance.
The 200 ohms is the value for the series resistor component.
