One of the most widely used passive components in electronic devices, it employs a ceramic dielectric + multilayer stacked structure, is non-polar, and has a small size. It has excellent high-frequency characteristics, low equivalent series inductance (ESL), and high reliability, and is widely used in power supply decoupling, signal filtering, coupling, resonance and other scenarios on PCB boards. It is a fundamental component of consumer electronics, communications, and industrial equipment.
