Unlike resistor color codes, a standard for capacitor labeling never really happened. This means when an obsolete part fails, only a "good guess" of the component values can be attempted. My guess is that this is a 0.022 micro farad capacitor with a DC voltage rating of 1000V. The package looks like one of the plastic film (polystyrene, polyester, polypropylene, etc.) dielectric capacitors.

A sort-of-resistor-like labelling did actually happen, these items

being colloquially known as "bumblebee" capacitors. As far as I can make out they were made only by Sprague, but are valued excessively by retro electric guitar enthusiasts.

Those things which identify its electrical characteristics are its parameters.

Lol! Was this judged to be a homework question?

Probably not.

They are a guide as to the correct selection of the capacitor(s), either as new or, as in the case of the one pictured, as replacement(s).

...and the K means 10% tolerance.

Various capacitor vendors use different numbering approaches, so the individual specs must usually be consulted. CTR is an Indian electrical/electronics manufacturer and, fortunately, you can request detailed information about their capacitors via their web site:

http://www.ctr.in/products/electronic-and-electrical-capacitors.html#horizontalTab2

This capacitors series uses polyester film and foil construction within a plastic box that is vacuum impregnated with epoxy resin. This allows them to be used in high-current pulse and snubber applications at low pulse rates. It is NOT suitable for RF use due to excessive dielectric loss. The series has a usable temperature range of -45 to +85C. This particular capacitor is 0.022uF at 1000 VDC. More detail should be available directly from the vendor.
