Class D audio amplifier chips are a type of amplifier that uses switching technology to convert an input audio signal into a high-frequency pulse-width modulated (PWM) signal. These amplifiers are ...

RoHS Compliant LED Drivers are designed to meet the Restriction of Hazardous Substances (RoHS) directive, which limits the use of specific hazardous materials found in electrical and electronic ...

RoHS Compliant Power Transformers are transformers that adhere to the Restriction of Hazardous Substances (RoHS) directive, which restricts the use of specific hazardous materials found in electrical ...

Pillow block bearings, sometimes referred to as plummer block bearings, are mounted bearings that are used to provide load support for a rotating shaft. Their mounting surface is on a plane parallel ...

Check valves are self-activating safety valves that permit gases and liquids to flow in only one direction. The purpose of a check valve is to prevent process flow from reversing in the system which ...

This large library of free industrial online webinars available from GlobalSpec's partners covers the big trends in engineering - everything from electrical engineering and power electronics to ...

Ball valves are quarter-turn, straight-through valves that have a round closure element with matching rounded seats that permit uniform sealing stress. The valve gets its name from the ball that ...

V-belt pulleys (also called vee belt sheaves) are devices which transmit power between axles by the use of a v-belt, a mechanical linkage with a trapezoidal cross-section. Together these devices offer ...

Venturi vacuum generators create vacuums using a venturi chamber designed to move gases or fluids out of a region of space. Venturi or fluid jet vacuum generators rely on the flow of compressed air, ...

Gas valves are flow control devices used to handle and control the flow of gases such as liquefied petroleum, oxygen, and sour and natural gas. They are available in a variety of metal or plastic ...

Butterfly valves are quarter-turn rotary motion valves used as throttling valves to control flow through a system. They can be used with many different media. Butterfly valves offer several advantages ...

Hydrostatic bearings and hydrodynamic bearings are fluid film bearings that rely on a film of oil or air to create a clearance between the moving and stationary elements. Although they may be similar ...
