The T540B107M004CH86107280 (hereafter referred to as T540) is a tantalum polymer capacitor, a type of capacitor designed and manufactured to meet the stringent standards of today\'s electronic applications. It has a parallel-plate construction and is used extensively in a wide range of high-frequency applications, including mobile, laptop and desktop computers, display monitors, and military and aerospace applications. This article will provide an overview of the T540\'s application field and working principle.The T540 is a non-polarized, low-profile, low-capacitance, surface-mount tantalum-polymer capacitor. It features a maximum voltage rating of 4.5 VDC, a capacitance range from 10 to 107 µF, and a capacitance tolerance of ±10%. The T540 is particularly well suited for high frequency applications, as it features a low ESR (Equivalent Series Resistance) of 0.2 ohms, enabling high-speed switching and data-rate operation. Furthermore, the T540\'s ceramic-filled polymer dielectric provides increased tenability, making it suitable for high-temperature environments, such as automotive and industrial applications.In terms of its working principle, the T540 utilizes a parallel-plate type of construction: two conductive plates separated by a dielectric. When a potential difference is applied across the plates, the electric field within the dielectric material produces a space charge. This space charge induces an electric field that opposes the applied field and thus produces an electric capacitance, or “capacitor”, storing an electric charge proportional to the potential difference of the applied voltage. When removing the potential difference, the charge remains stored in the capacitor, and it continues to store the charge until its maximum capacitance is reached.In summary, the T540 tantalum-polymer capacitor is a low-profile, low-capacitance, surface-mount capacitor well suited for high-frequency applications. Its relatively low ESR and ceramic-filled polymer dielectric enable its use in high-temperature environments, and its parallel-plate construction allows for the storage of electric charge when a given potential difference is applied.
