18125C684KAT2A Description

Short technical summary and product information.

The Kyocera AVX 18125C684KAT2A is a surface mount multilayer ceramic capacitor (MLCC) with a capacitance of 0.68µF and a voltage rating of 50V. It features a ±10% capacitance tolerance and uses X7R dielectric, which provides a capacitance variation of ±15% over the operating temperature range of -55°C to +125°C. X7R is a Class II dielectric material suitable for applications where moderate capacitance changes under voltage and temperature are acceptable.

 

This capacitor is housed in an 1812 (4532 Metric) package with dimensions of 4.50mm length, 3.20mm width, and a maximum thickness of 1.27mm. It is designed for surface mount assembly and is supplied in tape and reel packaging. The part is RoHS3 compliant, REACH unaffected, and has an MSL of 1 (unlimited).

 

Typical applications include decoupling, filtering, and bypass circuits in industrial and consumer electronics where stable performance over a wide temperature range is required. The dissipation factor is ≤12.5% for 25V and 16V ratings, and insulation resistance is 10000 MΩ or 500 MΩ-µF whichever is less. Dielectric strength is 250% of rated voltage with no breakdown or visual defects.
