1. Can I replace film capacitors with ceramic capacitors?

In many cases, ceramic capacitors can be used to replace film capacitors, especially when smaller size and lower cost are required. However, it is important to note that ceramic capacitors may have different temperature coefficients and self-healing characteristics, which may affect performance in a specific application.
2. Why are mica capacitors so expensive?

Mica capacitors are expensive because of their excellent electrical properties (such as very low dissipation factor and stable temperature coefficient) and their high production costs.
3. Do ceramic capacitors degrade over time?

The capacitance value of ceramic capacitors may decrease slightly over time and environmental factors, but this is usually a slow process.
4. What is the difference between Class 1 and Class 2 ceramic capacitors?

Class 1: has high accuracy and stable temperature coefficient, suitable for precision circuits.
Class 2: has higher capacitance value, but larger temperature coefficient and tolerance, suitable for general applications.
