A high-precision, pin-compatible upgrade with ±5% tolerance, ideal for circuits requiring stable capacitance.
Find reliable replacements for the Samsung CL21B105MBFNNNE, a 1µF 50V 0805 ceramic capacitor. This guide provides verified alternatives with improved tolerance and voltage ratings for enhanced circuit performance and reliability.
Candidates meet or exceed key electrical ratings. Tighter tolerance is a low-risk upgrade.
All candidates share the same 0805 package, ensuring form and fit compatibility.
Yes, several pin-compatible replacements exist. Candidates like UMK212B7105KGHT offer the same package and electrical values but with improved tolerance.
Upgrade to a part with tighter tolerance like TCC0805X7R105J500FT (±5%) for better performance, or TCC0805X7R105K101FT for a higher 100V rating.
The primary risk is minimal as all suggested alternatives are upgrades. However, in sensitive analog circuits, a change in tolerance could slightly alter filter or timing characteristics.
