What does 1KV stand for?
Yes, it’s rated for 1000V (1KV), a high voltage rating. If this cap is part of a safety-critical system (and at that voltage, very likely) review your circuit closely. If there’s line voltage involved, consider using a safety rated X or Y-cap which is designed to fail in a way that will render your circuit safe.
How many terminals a capacitor has?
two terminals
A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals.
What does kV mean on a disc capacitor?
I’ve tried several “capacitor code calculators” but none of them mentions “KV” (only K, which is indeed a tolerance code). Yes, it means 1kV (DC) rating. Looks like 1 nF, 1kV capacitor. Tolerance code is usually on the same line as capacitance, for example 102K would be 1nF +-10%.
What are the capacitor values on a ceramic disc?
Ceramic Disc Capacitor Values / Code / Label 1 Standard Capacitor Values. Here is a list of the currently available ceramic disc capacitors consisting of standard values. 2 Voltage Code. The brown coloured ones usually have an underline below the marking, which means 50 V / 100 V. 3 Temperature Code.
What should the voltage be on a capacitor?
If there is no underline, then the rating is 500 V, assuming the manufacturer follows the marking scheme. The epoxy-coated capacitors usually have the letters 1KV, which indicates 1000 V, and 2KV indicating 2000 V. Sometimes capacitors do not have any markings regarding voltage rating and you have to look up the documentation of that component.
What does the black mark at the top of a capacitor mean?
Sometimes capacitors do not have any markings regarding voltage rating and you have to look up the documentation of that component. However, manufacturers often use a combination of the above marking scheme. The black mark at the top of the disc represents the operating temperature range, which is approximately -25-°C to +85-°C.
