5.1 Loop Filter and Vibration Nonsensitive Capacitors
The capacitors used on the EVM are X7R, which are ferromagnetic and therefore are sensitive to vibration due
to the piezoelectric effect. TI recommends to use non-ferromagnetic capacitors such as NP0, C0G, or Tantalum
for applications in which optimal performance is required in the presence of vibration.
At and below 47 nF, C0G/NP0 capacitors are available in 0805 sized packages. For values 0.1 µF and above,
Tantalum capacitors may be considered for vibration immune loop filter components.
