Power Supplies A to Z : "X"

We've included this handy glossary to help with the terminology & abbreviations relating to power products. Pick a letter below to begin, or download the glossary to refer to it whenever you like.

A B C D E F G H I J K L M N O P Q R S T U V W X-Z #

X

Symbol for Reactance.


X Capacitors

EMI filter capacitors across the line that meet the requirements of certain regulatory agencies.


XC

Symbol for Capacitive Reactance.


XL

Symbol for Inductive Reactance.


Y Capacitors

EMI filter capacitors between line and ground that meet the requirements of certain regulatory agencies.


Yocto

SI prefix multiplier. Multiplies by 10-24. So 100 yF = 100 x 10-24 F. Written as 'yocto'. Abbreviated to 'y'.


Yotta

SI prefix multiplier. Multiplies by 1024. So 100 YF = 100 x 1024 F. Written as 'yotta'. Abbreviated to 'Y'.


Z

Symbol for Impedance.


Zener Diode

A diode that permits current to flow both in the forward direction (like a conventional diode) and in reverse direction. When current flows in the reverse direction, Zener diodes are designed to drop a specified amount of voltage (the Zener Voltage). They are used primarily to regulate the output voltage of low power regulators.


Schematic Symbol for a Zener Diode

Zener Voltage

The reverse voltage at which breakdown occurs in a Zener Diode.


Zepto

SI prefix multiplier. Multiplies by 10-21. So 100 zF = 100 x 10-21 F. Written as 'zepto'. Abbreviated to 'z'.


Zetta

SI prefix multiplier. Multiplies by 1021. So 100 ZF = 100 x 1021 F. Written as 'zetta'. Abbreviated to 'Z'.
