The T-shaped shell refers to the shell of the tantalum capacitor. Tantalum capacitors are widely used in electronic equipment for their high reliability and capacitance stability. The T-case is designed to provide a protective enclosure for the internal components of the capacitor, ensuring its durability and resistance to environmental factors such as temperature, humidity and mechanical stress. This type of housing usually has a cylindrical shape and is made of a material compatible with the performance requirements of the capacitor. Overall, T-cases play an important role in ensuring the functionality and lifetime of tantalum capacitors.
