In and Out

A capacitor acting as an HF short circuit must have low lead and PC track inductance, so each supply capacitor must be located very close to the two terminals of the IC it is decoupling. It is also important to choose capacitors with low internal inductance–usually ceramic ones. Many ICs contain circuitry which generates HF noise on their supply.

Why Does My Motor Need A Capacitor?

With a capacitor connected in series to the secondary winding, the magnetic field it produces lags behind the magnetic field generated by the primary winding.

A Run Capacitor keeps a motor running smoothly with no big up and down spikes. ... I installed the fan motor and connected the brwn and brwn/wht wires to the capacitor that it came with. When I turn on the a/c system now it dont get cold, but the fan works now. Before the fan went out it would blow cold.

Why a small capacitor is connected across DC motor terminals?

The capacitor connected across the terminals of a DC motor is typically a ceramic disc or metal film type. This capacitor is often referred to as a bypass capacitor or a snubber capacitor. The primary reason for using a capacitor across the terminals of a DC motor is to suppress or ''snub'' electrical noise generated by the motor.
