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'.
