This comprehensive review explores the profound influence of capacitor technologies on circuit design efficiency, performance characteristics, and environmental sustainability. Capacitors, as fundamental passive components, play a pivotal role in electrical circuits by facilitating functions such as filtering, energy storage, and coupling [1]. The choice of capacitor type significantly impacts circuit performance, affecting parameters including capacitance, frequency response, temperature stability, and voltage handling. Advancements in capacitor technology, such as integration into integrated circuits (IC), enhance circuit efficiency by reducing parasitic effects and improving signal integrity [2]. The environmental impact of capacitors is substantial, with significant implications for material extraction, manufacturing, and disposal. As the electronics industry evolves, adopting sustainable practices like recycling and repurposing capacitors becomes crucial. This review integrates lifecycle assessments and comparative analyses of disposal methods to provide insights into designing and managing capacitor technologies for a greener environment. This literature review contributes to the development of more sustainable electronic systems by highlighting the interplay between capacitor technology, circuit design efficiency, and environmental stewardship. Optimizing capacitor selection and disposal practices enhances circuit performance while minimizing environmental impact, aligning with broader efforts to reduce electronic waste and foster a sustainable electronics industry. This review supports the advancement of environmentally conscious circuit design practices through a comprehensive understanding of capacitor technologies and their lifecycle implications.
