Symbol for Reactance.
EMI filter capacitors across the line that meet the requirements of certain regulatory agencies.
Symbol for Capacitive Reactance.
Symbol for Inductive Reactance.
EMI filter capacitors between line and ground that meet the requirements of certain regulatory agencies.
SI prefix multiplier. Multiplies by 10-24. So 100 yF = 100 x 10-24 F. Written as 'yocto'. Abbreviated to 'y'.
SI prefix multiplier. Multiplies by 1024. So 100 YF = 100 x 1024 F. Written as 'yotta'. Abbreviated to 'Y'.
Symbol for Impedance.
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.
The reverse voltage at which breakdown occurs in a Zener Diode.
SI prefix multiplier. Multiplies by 10-21. So 100 zF = 100 x 10-21 F. Written as 'zepto'. Abbreviated to 'z'.
SI prefix multiplier. Multiplies by 1021. So 100 ZF = 100 x 1021 F. Written as 'zetta'. Abbreviated to 'Z'.
