TCAN1042-Q1: decoupling capacitance

Part Number: TCAN1042-Q1

Team,

My customer uses 0.1uF decoupling capacitor. After the worst case tolerance calculation, they got minimum capacitance = 0.05 uF and maximum capacitance = 0.14uF for the worst case situation. They would like to confirm that this much capacitance is okay as decoupling capacitance for this part?

Thanks

Viktorija

  • Viktorija,

    Using this range for decoupling capacitance is okay. Is the tolerance calculation just based on ceramic capacitance tolerance degradation?

    Regards,

    Yes. This considers Aging, Vibration, Temperature, DC bais effects, etc.
