Metal oxide varistors (MOV) are semiconductors that protect electronic components and systems from transient voltages

Varistors are voltage-clamping devices that can absorb current without damage.

Circuit protection devices are used to protect electronic components from unwanted transients such as current and voltage surges, electrostatic discharge (ESD), lightning, spikes and other signals that can imperil the operation or damage the component.

Resistors and potentiometers are passive electronic components that oppose the flow of either alternating current (AC) or direct current (DC).

Ball screws, lead screws, and ACME screws are used to convert rotary motion or torque into thrust or linear motion

Lead, tin and low melting alloys are non-ferrous alloys used in the manufacture of solder, semiconductor, battery and decorative products

Radial or deep groove bearings can handle radial and axial loads to varying degrees, but are typically used when the primary load is in the radial direction
