The recommended land pattern for the T93YB101KT20 can be found in the Vishay Sfernice application note AN10343, which provides guidelines for PCB layout and assembly.
Thermal derating of the T93YB101KT20 should be done according to the guidelines provided in the Vishay Sfernice application note AN10005, which explains how to calculate the maximum allowable power dissipation based on the operating temperature.
The maximum allowable voltage for the T93YB101KT20 is 100V, as specified in the datasheet. However, it's recommended to derate the voltage according to the operating temperature to ensure reliable operation.
The T93YB101KT20 is designed for general-purpose use and may not be suitable for high-frequency applications. For high-frequency applications, it's recommended to use a capacitor specifically designed for high-frequency use, such as the Vishay Sfernice T93 series with a 'HF' suffix.
To ensure the reliability of the T93YB101KT20 in a humid environment, it's recommended to follow the guidelines provided in the Vishay Sfernice application note AN10006, which explains how to protect the capacitor from moisture and humidity.
