Touchstone Semiconductor's Martin Tomasz explains how to interfact to capacitive touch sensors using basic 555-timer circuits.

The DI was called Circuit measures capacitance or inductance, and it was by the prolific contributor Jim McLucas. Jim had another capacitance measurement idea back in 2009. Monsieur Laagel’s proof was ...

With these parameters, the equivalent discharge resistance r disch can be used to determine C h, the hold-up capacitance. Note that V C is essentially equal to V HoldUp (t) here.

However, a capacitance meter is a handy piece of gear, relatively simple to build, and you should be able to get it working without an existing capacitance meter. [gavinlyonsrepo] presents a ...

The discharge is made through D3. The average current in R8 is proportional to the capacitance. The voltage that charges the capacitor is the one set in U2 – 5.74V – plus the drops in D1. The voltage ...

Capacitance and energy stored in a capacitor can be calculated or determined from a graph of charge against potential. Charge and discharge voltage and current graphs for capacitors.

Capacitance is typically 0.31pF (oV, 1MHz, 25°C – 0.45pFmax), and operation is across -55 to 150°C. Electrostatic discharge rating to IEC 61000-4-2 s 10kV for contact discharge and 15kV for air ...
