18121C684KAT2A Description

Short technical summary and product information.

The 18121C684KAT2A is a surface-mount multilayer ceramic capacitor (MLCC) manufactured by Kyocera AVX. It offers a capacitance of 0.68 µF with a rated voltage of 100V DC and a tolerance of ±10%. The capacitor uses X7R dielectric, which is a Class II ceramic material providing a capacitance change of ±15% over the operating temperature range of -55°C to 125°C.

 

This component is housed in a standard 1812 (4532 Metric) package with dimensions of 4.57mm length and 3.20mm width, and a maximum thickness of 1.02mm. The terminations are plated with nickel and tin, compatible with surface-mount soldering processes. The part is supplied in tape and reel packaging suitable for automated assembly.

 

X7R capacitors are suitable for general purpose applications such as bypass, decoupling, and filtering in industrial and consumer electronics. The dissipation factor is ≤10% for voltage ratings of 50V DC and above, and the insulation resistance is 10000 MΩ or 500 MΩ-µF, whichever is less.

 

This part is identified under the manufacturer part number 18121C684KAT2A and is also available through distributors with cross-reference numbers such as 478-11637-2-ND.
