buffer capacitor

buffer capacitor

[′bəf·ər kə′pas·əd·ər]
(electronics)
A capacitor connected across the secondary of a vibrator transformer or between the anode and cathode of a cold-cathode rectifier tube to suppress voltage surges that might otherwise damage other parts in the circuit.

The low power design of the device ensures a current consumption of less than 1 microamp, meaning that the energy stored in a 10mF buffer capacitor is sufficient to measure elapsed time for power failures with durations of up to five hours.
When combined with all necessary external components (filter capacitor and buffer capacitor or battery), the overall footprint of the circuit is only approximately 15mm2 (0.
