The capacitor 510 specifically. I have not been able to figure this component out. Please anyone? Thanks in advance Tom October 29, 2025 at 9:34 pm #37740 BillyModerator 510 is the code for a 51pf capacitor The first 2 digits are significant numbers the 3rd digit the number of zeros so 51 with no zeros October 29, 2025 at 9:39 pm #37741 Thomas a MeachamParticipant Thank you for the FAST reply. I really appreciate your help October 29, 2025 at 9:58 pm #37743 AnonymousInactive Wouldn’t that be 510pf or 51n?
