C1210C226K3RACTU-Multilayer Ceramic Capacitors MLCC – SMD/SMT 25Vol 22uF X7R 1210 10% — BOLTON SKU 67752.
About the C1210C226K3RACTU MLCC, 22uF 25V X7R 1210
This is a KEMET commercial-grade surface-mount multilayer ceramic chip capacitor. Reading the ordering code against the manufacturer’s field table: C is the ceramic chip family, 1210 the EIA case size, C the standard specification, 226 a capacitance code of 22 µF, K a tolerance of ±10%, 3 a rated voltage of 25 VDC, R the X7R dielectric, A the failure-rate and design field, C a 100% matte tin plated termination and TU unmarked 7-inch reel packaging. X7R is an EIA Class II temperature-stable dielectric with an operating temperature range of −55 °C to +125 °C and capacitance change limited to ±15% across that range. Being Class II, capacitance also varies predictably with applied DC voltage and with time, which is normal for the material class and is why X7R is specified for bulk and decoupling duty rather than for tuned circuits. The 1210 case is released for reflow soldering only, and the part is non-polar and RoHS compliant.

Typical applications
A 22 µF X7R part at 25 VDC is a bulk and decoupling capacitor: input and output reservoirs around DC-DC converters and point-of-load regulators, rail smoothing on 12 V and lower distribution, and local energy storage next to processors and drivers where a tantalum or electrolytic part is to be avoided. The 1210 case is the size normally reached for when this capacitance is needed at a 25 V rating. Reflow-only mounting and the Class II voltage coefficient should both be allowed for at design stage.
