How do I choose a capacitor?
Select a tolerance that is compatible with the demands of your circuit. Make sure the chosen capacitor’s physical dimensions fit into the design of your circuit. While through-hole capacitors are still employed in some applications, surface-mount capacitors are frequently used in current electronics.
Why should you choose a capacitor?
Choosing the right capacitor for an application can make a significant difference in the performance, reliability, and efficiency of products such as power supplies for defense, aerospace, medical technology, critical energy infrastructure, or fast EV chargers.
What type of capacitor should I use?
In both cases the capacitors should have low leakage current and have adequate precision. The best choices for feedback capacitors are class 1 ceramic capacitors, polystyrene film capacitors, and for high temperature applications, polycarbonate film capacitors.
Do different types of capacitors match the working frequency?
Despite both being used for filtering and energy storage discharge, when the working frequency is fixed, consideration must be given to whether the frequency characteristics of different types of capacitors match the circuit's working frequency. This is because each type of capacitor has its own suitable frequency range.
Are all capacitors the same?
Capacitors are essential components in many electronic circuits as they store and release electrical energy, filter out unwanted signals, and perform other functions. However, not all capacitors are created equal, and different types of capacitors have varying characteristics, advantages, and limitations.
How to choose a capacitor for aerospace circuits?
For aerospace circuits to meet usage requirements, capacitors must have outstanding temperature characteristics.
