KEMET T491 22µF 35V Surface Mount Tantalum Capacitor, X-Case

The KEMET T491X226K035AT is an industrial-grade surface mount tantalum capacitor, designed to deliver reliable performance in demanding electronic applications. It utilises a solid manganese dioxide (MnO2) electrolyte and is engineered for compatibility with highly automated surface mount technology (SMT) assembly processes, making it a leading choice for modern, high-density PCB designs. This capacitor combines KEMET's globally recognised solid tantalum expertise with advanced materials and manufacturing techniques to offer outstanding performance and long-term value.

With a capacitance of 22 microfarads (µF) and a ±10% tolerance, it provides stable and precise charge storage. The component is rated for a 35V DC working voltage and can operate across a wide temperature range from -55°C to +125°C. It features low equivalent series resistance (ESR) of 0.7 ohm, which is crucial for efficient power decoupling and filtering, helping to minimise voltage ripple and heat generation in circuits.

Constructed in the compact 2917 (7343 metric) ‘X’ case size, it saves valuable board space. The capacitor boasts symmetrical, compliant terminations for reliable solder joint integrity and features a halogen-free epoxy encapsulation that is compliant with the UL94 V-0 flammability standard. This product meets or exceeds the rigorous EIA Standard 535BAAC.
