12105A123FAT2A

This is a surface mount multilayer ceramic capacitor (MLCC) manufactured by Kyocera AVX, part number 12105A123FAT2A. It offers a nominal capacitance of 0.012 µF with a tight ±1% tolerance and a DC voltage rating of 50V. The dielectric is C0G (NP0), which provides a near-zero temperature coefficient, ensuring stable capacitance over a wide temperature range.

The capacitor operates from -55°C to 125°C, making it suitable for demanding environments. The C0G/NP0 material exhibits low dissipation factor and high insulation resistance, ideal for resonant circuits, timing, and filtering where stability is critical.

The component is housed in a standard 1210 (3225 Metric) package with dimensions 3.20mm x 2.50mm and a maximum thickness of 0.94mm. It is designed for surface mount assembly and is compatible with reflow soldering processes. The part is RoHS3 compliant and has an MSL rating of 1 (unlimited), though these compliance claims are unverified.

Typical applications include general purpose coupling, decoupling, bypass, and noise suppression in automotive, consumer, and industrial electronics. The ±1% tolerance and NP0 stability make it particularly useful in precision circuits.
