Capacitors are essential electronic components used in various MRO and automation applications for storing and releasing electrical energy. They are widely utilized in power supply systems, motor controls, circuit protection, and signal filtering. Common types include electrolytic capacitors (for high capacitance needs), ceramic capacitors (for stability and compact size), and film capacitors (for high-frequency applications). Key features include capacitance value, voltage rating, tolerance, and temperature stability, making them critical for ensuring efficient and reliable operation in industrial equipment, automation systems, and electronic devices.
