| SECOND |
| The basic unit of measure of time, equivalent to "the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium-133 atom". For our purposes, one "second" is 1/60th of a minute. |
| SERIES RESONANCE, Fs |
| The condition that exists when a crystal unit is operated without the presence of load capacitance. "Series Resonance" is frequently shortened to the word "series". See "Load Resonance" |
| SHUNT CAPACITANCE, C0 |
| A parameter associated with a quartz crystal unit, used to identify the capacitance resulting from the presence of the electrodes plus stray capacitance associated with the holder. |
| STORAGE TEMPERATURE |
| The minimum and maximum temperatures that the device can be stored or exposed to when in a non-oscillation state. After exposing or storing the device at the minimum or maximum temperatures for a length of time, all of the operating specifications are guaranteed over the specified Operating Temperature Range. |
| SINE WAVE |
| A periodic waves that can be represented by a sine curve. The amplitude of such a wave is a function of the sine of a linear quantity such as phase or time. |
| SMD |
| The abbreviation for "Surface Mount Device". |
| SPUR |
| A substitution for the term "Spurious Frequency Response". The word "spur" is used to refer to a frequency occurring at some point higher than the desired mode but lower than the next overtone. |
