Too much pressure is not good on your RF Caps
The Greek root of the word piezo means "to press". In
1880, Jacques and Pierre Curie discovered that pressure
applied to a quartz crystal creates an electrical potential
on the crystal. Likewise, they also discovered that an
electrical potential impressed on the crystal creates.
