KEMET T491A105K025AT Tantalum Capacitor

The KEMET T491 series MnO2 tantalum chip capacitors are high-reliability surface-mount components suitable for industrial applications. They feature polarized manganese dioxide dielectric, molded construction, and are available with tin terminations for excellent solderability. These capacitors support capacitance values from 0.1 µF to 1000 µF, tolerances of ±10% or ±20%, and operate effectively over a temperature range of -55°C to 125°C. Designed for modern automated assembly, they provide stable performance with low leakage current, making them ideal for power supply filtering, decoupling, and timing in demanding electronic circuits.
