Polar capacitors or polarized capacitors are such type of a capacitor whose terminals (electrodes) have polarity; positive and negative. The positive terminal should be connected to positive of supply and negative to negative. Reversing the polarity will destroy the capacitor. These type of capacitors are only used in DC applications.
The polarity of a capacitor refers to the distinct orientation of its terminals, typically marked as positive (+) and negative (-). This property is determined by the construction and internal structure of a component. Thus, recognizing the polarity of capacitors is fundamental for ensuring their proper integration into electronic circuits.
1. 2. Non-polar Capacitors Polar capacitors or polarized capacitors are such type of a capacitor whose terminals (electrodes) have polarity; positive and negative. The positive terminal should be connected to positive of supply and negative to negative. Reversing the polarity will destroy the capacitor.
You can find positive and negative polarity markings on the capacitor’s casing, and it’s important to pay attention to these markings and connect the circuit correctly when using them. On the other hand, ceramic capacitors and film capacitors are non-polarized and can be installed in any direction. Here’s a brief overview of these capacitor types:
Non-polarized capacitors come in a variety of shapes and sizes, each of which has its own unique characteristics and applications. The most common types include ceramic, electrolytic, mica, paper, plastic film and tantalum capacitors.
They offer a much higher dielectric constant than other types of non-polarized capacitors, making them suitable for applications with high voltages such as power supplies and motor controllers. Polypropylene capacitors, also known as PP caps or PPCs, are a type of non-polarized film capacitor.
