Choke

Product Details:

As the name implies, a choke cuts off or restricts high-frequency alternating current (AC). It only permits direct current (DC) to pass through its conductor. A choke eliminates AC and allows only DC currents to a load resistor or other load components.

Chokes protect insulation from damage caused by steep rises in current in circuits by facilitating a gradual rise and fall of current instead. Chokes can also break down voltage, allowing transient voltages across fluorescent tubes by keeping gas voltages from exceeding system voltages.
