Do you looking for high voltage capacitors for your circuit..?
I just get this table about capacitor working voltage for each type of capacitor (ceramic, electrolytic, tantalum, mylar polyester and mylar metal film capacitor).
Ceramic
Electrolytic
Tantalum
Mylar ...

Electrolytic capacitor or electrolytics condensator or we often call "ELCO" is a type of capacitor that uses an ionic conducting liquid as one of its plates. Typically with a larger capacitance per unit volume than other types, they are valuable in relatively high-current and low-frequency electrical circuits. This is especially ...

LED (Light Emitting Diode) is a semiconductor diode that emits light when an electric current is applied in the forward direction of the device, as in the simple LED circuit. The effect is a form of electroluminescence where incoherent and narrow-spectrum light is emitted from the p-n junction.
LEDs are widely ...

A transformer can be viewed as a converter that can increase voltage and lower current, or vice versa. It only works when using AC.
The transformer is effectively a magnetic circuit. The transformer has two or more coils of wire wrapped about a common core.
The ideal relationship is:

In this reading we are going to talk about capacitance. I have to make a distinction here between capacitor and capacitance. A capacitor is a device, whereas capacitance is an electrical property. First we will discuss the capacitor and then the property of capacitance.
We will avoid mathematics where possible.
Construction
As you ...

Resistors can play any of numerous different roles in electrical and electronic equipment. Here are a few of the more common ways resistors are used.
Voltage division
You’ve already learned a little about how voltage dividers can be designed using resistors. The resistors dissipate some power in doing this job, but the ...

WHAT A TRANSFORMER TAP CHANGER IS AND WHAT IT DOES.
A tap changer is a device fitted to power transformers for regulation of the output voltage to required levels. This is normally achieved by changing the ratios of the transformers on the system by altering the number of turns in one ...

Here the resistor color code for 4 band color and 5 band color.
Usually the 5 band color resistor also known as metalfilm resistor (blue body color).
