| The abbreviation for "PicoFarad" used to describe a fractional part 10-12 (one-trillionth) of one Farad. Pico: A prefix used to describe a sub-multiple of a number. One Pico is one-trillionth 10-12 of a unit. |
| PIEZOELECTRIC EFFECT |
| A voltage produced between surfaces of solid dielectric (non-conducting substance) when a mechanical stress is applied to it. A small current may be produced as well. Certain crystals exhibit the effect. |
| PPM |
| The abbreviation for "Parts Per Million" a method of calculation used to specify the permissible frequency deviation of a crystal or oscillator. May also be seen as "PPM". Both are correct. |
| PULLABILITY |
| The amount the frequency can be made to deviate by varying the voltage on the control pin. |
