Could you identify this for me and lead me in the right direction?

Please take a look at these capacitors.

OK, what does the efk and 1K5 mean?

Hi Speedcrew,
Looking at the EFK marking, the E calls out 25 volts shown here on the datasheet. Take a look at Digikey part PCE4416CT-ND as an option, make sure to measure and verify the dimensions are correct. 1K5 is a lot code.

The datasheet is the best way to show the marking call out.
click here for datasheet

you have capacitance top then voltage next to series FK last the lot code

Thank you all.
This really helps.
Have a great day!
