Ultra High Frequency filter
Unit interval (used to describe jitter generation); user information; user interface
A SCSI interface label, where 160 refers to the maximum reliable throughput in megabits per second.
UMTS (Universal Mobile Telecommunications System) is a third-generation cellular standard based on the GSM standard and developed by the 3rd Generation Partnership Project (3GPP).
An uninterruptible power supply (UPS) is a device that maintains power in the event of a failure. A UPS commonly includes a battery that is kept charged and ready. When power fails, the battery supplies power, as long as it lasts. When the battery fails,
An uninterruptible power supply or uninterruptible power source (UPS) is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails.
A unique identification technique
A factory-programming service for 1-Wire EPROM chips with customer-specified data. Service provides one serialization file for customers to create identifiers in silicon.
A device which provides frequency conversion to a higher frequency, e.g., in digital broadcast-satellite applications.
Uniform/universal resource locator
Universal Serial Bus (USB): A standard port that enables you to connect external devices (such as digital cameras, scanners, keyboards, and mice) to computers. The USB standard supports data transfer at three rates: low speed (1.5MBps), full speed (12Mbps
USB-C, formally known as USB Type-C, is a 24-pin USBconnector system, which is distinguished by its two-fold rotational-symmetrical connector.

Undervoltage lockout
Ultra-Wideband (UWB) is a communications technology that employs a wide bandwidth (typically defined as greater than 20% of the center frequency or 500MHz). UWB is usually used in short-range wireless applications but can be sent over wires. Ultra-Wideban
