T491A685K004AH capacitors are tantalum capacitors. Tantalum capacitors, sometimes referred to as ceramic capacitors, are non-polarized components that store energy in an electrostatic field when connected in a circuit, providing high capacitance over a wide range of temperatures, frequencies, and voltages. As such, they are widely used in a variety of electronic applications, including automotive, military, industrial, and consumer applications.

T491A685K004AH capacitors are small, surface-mount devices, making them well-suited for use on space-constrained printed circuit boards (PCBs). Additionally, because of their non-polarized nature, they are more tolerant than polarized devices of impulse and short circuit failures. These devices are capable of operating at temperatures of up to 85 degrees Celsius (°C) and have a rated voltage of 10 Volts (V).

The T491A685K004AH capacitor works on the principle of capacitance. When connected in an electrical circuit, it acts as a container of electrical charge. As an electric current passes through the capacitor, it collects electrical charge, which is then stored in the device’s dielectric. The capacitor will then release this stored energy upon demand, depending on the circuit’s needs. The capacitance of a device is determined by the ratio of the charge stored in the dielectric to the voltage applied to it.

T491A685K004AH capacitors are designed for use in a range of applications. This includes, but is not limited to, high-density PCBs, aerospace and avionics systems, automotive systems, memory backup and voltage-spike protection circuits. Additionally, these capacitors are also used for filtering, bypassing and decoupling in high frequency, digital circuits that require a small, low ESR (equivalent series resistance), high capacitance device.

In summary, T491A685K004AH capacitors are small, non-polarized components used for storing electrical energy in applications requiring high capacitance over a wide range of temperatures, frequencies, and voltages. They can be used for filtering, bypassing, decoupling and protecting circuits against voltage spikes and are capable of withstanding temperatures up to 85 degrees Celsius. Furthermore, due to their non-polarized nature, they are more tolerant of impulse and short circuit failures than polarized devices.
