5.1 Loop Filter and Vibration Nonsensitive Capacitors

The capacitors used on the EVM use are X7R which are ferromagnetic and therefore sensitive to vibration due
to the piezoelectric effect. It is recommended 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 uF and above
Tantalum capacitors may be considered for vibration immune loop filter components.
