AVX has published a new technical paper, “Dielectric Absorption of Multilayer Organic (MLO) Capacitors,” announcing that its MLO capacitors have been shown to exhibit the lowest dielectric absorption (DA) of any comparable technology, making them ideal for use in sample and hold (S/H) circuits. During the hold time of S/H circuits, the voltage across the capacitor is assumed to be a specified, predetermined number.  However, due to variances in dielectric absorption, that may not be the case, which could make the circuit vulnerable to voltage errors. 

Dielectric absorption measurements recorded during tests based on MIL-C-19778 indicate that AVX’s MLO capacitors exhibit 0.0015% DA. For comparison, Teflon, which is known to have very low DA, exhibits DA of 0.01% and NP0 ceramic exhibits 0.6% DA.
