Introduction to T541X108M004BH8705T541X108M004BH8705 is a type of tantalum-polymer capacitor, which are characterized by their relatively high capacitance in comparison to many other types of capacitors, as well as their ability to self-heal in some cases. It is a surface-mounted solid tantalum capacitor known for its excellent temperature stability, robust construction, low ESR (Equivalent Series Resistance) and high reliability. It is often used in high-frequency and high-temperature applications where capacitance, self-healing properties, and reliable operation are required.Application Field of T541X108M004BH8705 T541X108M004BH8705 is used in a variety of applications, such as in medical equipment, automotive electronics, power supplies, storage devices, telecom equipment and other high-reliability applications. It is most commonly used in power supplies and power management applications.Principle of OperationThe T541X108M004BH8705 comprises of a series of thin layers of tantalum pentoxide and polymer material. When the operating voltage is applied across the device, a voltage-dependent dielectric field is created, producing a capacitive element of undesirable frequency response. This is known as the leakage effect. To prevent this leakage and to ensure an acceptable frequency response, a discharge resistor is combined with the capacitor.The discharge resistor is placed in parallel to the capacitor, which allows current to flow through the capacitor, releasing any stored charge and ensuring that no undesired frequency response is present when the operating voltage is removed. When the device is re-energized, the capacitor is fully charged and the voltage is incrementally increased to obtain a high endurance level. ConclusionT541X108M004BH8705 is a highly reliable, robust, and temperature stable tantalum-polymer capacitor which is used in many applications requiring a high capacitance and reliable operation. Its operation utilizes a discharge resistor placed in parallel to the device to prevent leakage and ensure an acceptable frequency response. It is often used in medical equipment, automotive electronics, power supplies, storage devices, telecom equipment and other high-reliability applications.
