I am trying to duplicate a simple 556 circuit, this capacitor works, but when I try to substitute another cap, it doesn't work. I need to order a couple dozen of these but want to order the right thing:) tha cal in question is the flat green one with 103k in the number. I tried to measure this cap with my vom, and it read .025n. I dont know , that is accurate, since the .025n stays on my meter display with other components and wont zero out till I change away from capacitance and back again.enter )![enter image description here

That looks like a .01uF (10nF) 100V film cap. The code is 103K, you can find a chart of capacitor codes here:

  • \$\begingroup\$ @danielphantom can you please click accept this answer? Also you'll have an easy time finding these on Mouser or Digi-Key with their filters. Just look under passive components>capacitors>film capacitors and select .01uF for capacitance and 100V for DC voltage rating. \$\endgroup\$ – Avid Pro Tool Jun 1 '18 at 2:42
