Frequently Asked Questions
What is the difference between C0G and X7R for this application?
C0G (NP0) holds capacitance within ±30 ppm/°C across the full -55°C to +125°C range and shows no measurable aging. X7R varies up to ±15% with temperature and drifts with age and DC bias. For resonant circuits, precision filters, and audio signal paths, C0G is the correct choice. For general-purpose decoupling where volume matters more than precision, X7R is more common.
What are the physical lead dimensions?
Lead length is approximately 47mm based on photo observation. Lead spacing is not confirmed - verify against your PCB footprint before ordering.
Is this component polarized?
No. C0G ceramic capacitors are non-polarized and can be installed in either orientation.
Does this fit a standard through-hole PCB?
Yes - radial leaded, compatible with standard through-hole PCB layouts. Confirm lead pitch against your specific footprint. Lead pitch not confirmed from available data.
C0G dielectric was the answer to every circuit that couldn't afford to drift - oscillators, filters, audio stages that needed to behave the same at 25°C as at 85°C. These have been sitting unused, and that stability hasn't gone anywhere. Wire them in and let your circuit hold the line.
