12103G105ZAT2A

The Kyocera AVX 12103G105ZAT2A is a surface-mount multilayer ceramic capacitor (MLCC) with a nominal capacitance of 1 µF and a rated voltage of 25V. It uses a Y5V (F) temperature coefficient, which provides a capacitance change of -30% to +80% over the operating temperature range of -30°C to +85°C. The tolerance is -20% to +80%, making it suitable for general-purpose applications where precise capacitance is not critical.

This capacitor is housed in a standard 1210 (3225 Metric) package measuring 3.20mm x 2.50mm with a maximum thickness of 1.52mm. It is designed for surface-mount assembly and is RoHS3 compliant. The Y5V dielectric is a Class 2 ceramic material, offering high capacitance in a small footprint but with wider capacitance variation over temperature and voltage compared to Class 1 dielectrics like C0G.

Typical applications include decoupling, bypass, and filtering in consumer electronics, power supplies, and other general-purpose circuits. The 1210 package size provides a good balance of capacitance value and board space, suitable for designs requiring moderate capacitance in a compact form factor.
