The type of the capacitor is simply a description of what it is ...
Capacitors in loudspeakers explained -
Capacitor values are given in farad (F), usually in microfarad (µF) and volts (V). The farad value indicates what is known as a capacitor''s capacitance rating, or simply capacitance, which tells us how much energy a capacitor contains at a given voltage. A capacitor with a 1 farad capacity, can be charged with 1 volt.

Best HVAC Capacitor Guide: How to Find the Right One
Hence, the best capacitor for your HVAC system is the one recommended by the manufacturer. Dual run capacitors like the MaxRun MR-35 or the PowerWell PW-70 can be reliable replacement solutions, but only if they''re compatible with the HVAC system, you''re using. Was this guide to the best HVAC capacitors useful?
Should a Capacitor Be Used For ESD Protection?
The equivalent capacitor circuit shown here accounts for excitation of resonances by a fast transient, including an ESD event. Because of the voltage rating issue, and due to the inductance of typical high-voltage capacitors requiring large case sizes, it''s best to avoid capacitors as a form of ESD protection, especially on signal lines.
