Shelf Life: The capacitance, ESR and impedance of a capacitor will not change significantly after extended storage periods. However, the leakage current will very slowly increase.
SLC: Single Layer Ceramic.
SLCC: Single Layer Ceramic Chip.
SMD: Surface Mount Device. Common chip Capacitor sizes page.
SMT: Surface Mount Technology. Common chip styles include Cylindrical Can, Horizontal Mount, and Flat Chip. Chip capacitor Physical Size page.
Snubber Capacitor: A capacitor incorporated into a rapidly switched LC circuit to reduce emi by lowering the circuit resonant frequency and characteristic impedance.
Stability: The ability of a part to resist changes of characteristic values and coefficients.
a. Surge voltage (or current). Transient variation in the voltage or current at a point in the circuit; a voltage or current of large magnitude and short duration caused by a discontinuity in the circuit.
b. Temperature coefficient (TC). Change in capacitance of a capacitor per degree change in temperature. It may be positive, negative, or zero and is usually expressed in parts per million per degree Celsius (ppm/qC). Capacitor Value vs Temperature Chart
Substitution: A capacitor with a tighter tolerance can replace a losser tolerance capacitor. A higher working voltage capacitor may replace a lower working part. A tighter 1% capacitor may replace a 2 % temperature capacitor.
Synchro Capacitor: A unit containing three delta-connected capacitors. The synchro capacitor is used in synchro systems to increase the system’s accuracy by cancelling or reducing the phase shift introduced by synchro inductance.
