The capacitor physical size is directly proportional to the voltage rating in most cases. For instance, in the sample circuit above, the maximum level of the voltage across the capacitor is the peak level of the 120Vrms that is around 170V (1.41 X 120V). So, the capacitor voltage rating should be 226.67V (170/0.75). ... For ceramic capacitors ...
Often the datasheet for the chip specifically calls out how many and what size capacitors to use.

If nothing is specified by the datasheet, at a minimum, put a 0.1 uF ...
Can I use a 450v capacitor instead of 400v? Yes, you can use a 450v capacitor instead of 400v as long as the other characteristics (such as capacitance and temperature rating) are identical. Increasing the voltage rating may help protect your circuit from higher voltages, but it also means that it can be more expensive. Can I replace a 370v ...

There are multiple ways that ceramic capacitors can malfunction and some are: 1. Cracking of Ceramic Capacitor: Ceramic capacitors may undergo mechanical cracks due to too much physical stress i.e., bending of the board or pressure on the part. This excessive bending can develop short circuits between layers.
This article provides a comprehensive guide to ceramic capacitors, including an overview of their types, dielectric materials, and applications. Types of Ceramic Capacitors: Ceramic capacitors come in various types, each designed to meet specific requirements in electronic circuits. Here are the main types: 1. Surface-layer Ceramic Capacitors:
For ceramic capacitors, it''s also about temperature. The ambient temperature and ripple current will result in a temperature rise. That''s not to say that ceramics don''t age - certain dielectric materials ( Class 2 materials like X7R and Y5V) degrade in capacitance over time - Class 1 materials are largely immune to this.
What size capacitor do I need for a 1 hp motor? 1 HP = 746 Watts. Use our capacitance calculation formula. C(µF) = 746 x 80 x 1000 / (220 x 220 x 50) = 24.66 µF.

They are made in SMD (surface-mounted) technology and are widely used due to their small size. Ceramic capacitors are usually made with very small capacitance values, typically between 1nF and 1µF, although values up to 100µF are possible. Ceramic capacitors are also very small in size and have a low maximum rated voltage.
Each motor should have a small ceramic capacitor (10-100nF) across it to reduce RF (Radio Frequency) interference caused by brush arcing. A popular configuration is two 100nF capacitors in series, one from each motor terminal to the metal case.
