The recommended land pattern for the T93YA201KT20 can be found in the Vishay Intertechnologies' application note 'Land Pattern Recommendations for Vishay Tantalum Capacitors' (document number 40171). It provides detailed guidelines for designing a reliable and efficient PCB layout.
To minimize the impact of high ESR during high-frequency applications, it's essential to consider the capacitor's impedance characteristics. Vishay recommends using the T93YA201KT20 in conjunction with a low-ESR ceramic capacitor in parallel to reduce the overall impedance. Additionally, optimizing the PCB layout and using a low-inductance connection can help mitigate the effects of high ESR.
Although the datasheet specifies an operating temperature range of -55°C to +125°C, it's essential to note that the capacitor's performance and reliability may degrade above 105°C. For applications exceeding 105°C, Vishay recommends derating the capacitor's voltage and current ratings according to the temperature derating curve provided in the datasheet.
The T93YA201KT20 is designed to meet the requirements of various vibration and shock standards, including IEC 60068-2-6 and IEC 60068-2-27. However, it's crucial to ensure that the capacitor is properly mounted and secured to the PCB to prevent mechanical stress and damage. Vishay recommends following the guidelines outlined in the application note 'Mounting and Handling of Tantalum Capacitors' (document number 40172).
Vishay provides ESR values at 100 kHz in the datasheet. To determine the ESR at other frequencies, you can use the impedance vs. frequency curve provided in the datasheet or consult Vishay's application note 'Tantalum Capacitor Impedance vs. Frequency' (document number 40173). This will help you estimate the ESR at your specific operating frequency.
