What is a polystyrene capacitor?
Polystyrene capacitors are capacitors that have a dielectric made up of polystyrene. They come only in low values, usually 10pF to 47nF. Normally, their tolerance is 5% to 10% but high precision polystyrene capacitors are also available with tolerances of 1% and 2%.
Where are polystyrene capacitors used?
Polystyrene capacitors are often used as replacements for ceramic and mica capacitors in audio circuits. However this type of capacitor is not limited to only audio applications, it’s perfect for any application that requires a through hole high tolerance capacitor.
What is the capacitance range of a polystyrene capacitor?
Polystyrene Capacitors They come only in low values, usually 10pF to 47nF.
What are MLCC capacitors used for?
Multilayer ceramic capacitors (MLCCs) are generally the capacitor of choice for applications where small-value capacitances are needed. They are used as bypass capacitors, in op-amp circuits, filters, and more.
Are polystyrene capacitors polarized?
Types of Non-Polarized Capacitors are: Ceramic Capacitors. Silver Mica Capacitors. Polystyrene Capacitors.
What is polypropylene capacitor?
PP film capacitors are used for high-frequency high-power applications such as induction heating, for pulsed power energy discharge applications, and as AC capacitors for electrical distribution. The AC voltage ratings of these capacitors can range up to 400 kV.
Can you replace a polarized capacitor with a non polarized?
Non-polarized capacitors are supersets of polarized capacitors. Polarization is not a issue when replacing a electrolytic with a ceramic. In general, you can replace a polarized capacitor with a polarized or non-polarized capacitor with the same capacitance, and with a voltage rating of the original or higher.
How do you know if a capacitor is non polarized?
How Can You Tell If a Capacitor Is Non-Polarized? The negative lead on electrolytics is frequently indicated with arrows and “-” marks. The positive lead is noted on tantalums. The cap will not be polarized if it is ceramic, monolithic, film, polyester, or silver mica.
Does color of capacitor matter?
Each color painted on the capacitors body represents a different number. The color codes used to represent the capacitance values and capacitance tolerance is similar to that used to represent resistance values and resistance tolerance. Generally, the capacitors are marked with four or more color bands.
What is the difference between C0G and X7R?
C0G is a Class 1 dielectric, so it’s not included (more on this later). X5R and X7R are in Class 2, and Y5V is in Class 3. The first character indicates the lowest temperature that the capacitor can handle. The letter X (as in X7R, X5R) corresponds to –55°C.
Can you use non-polarized capacitor instead of polarized?
Polystyrene capacitors have been long time favorite capacitor of audiophiles and high-end audio manufactures. Polystyrene Film capacitors are very highly regarded due to their most desirable electrical characteristics such as exceptionally high insulation, low leakage, low dielectric absorption, low distortion and excellent temperature stability.

What is polystyrene made of?
Polystyrene was developed by a German apothecary in 1839 from the resin of the American sweet gum tree. After the tree’s distillation, it left an oily substance that came to be known as Styrol. After a few days, it thickened into a jelly called Styroloxyd.
