What Is an X2 Capacitor and Why Is It Used in EMI Suppression Applications?
Jan 27, 2026
Introduction
In modern electronic equipment, electromagnetic interference (EMI) is a common issue that can affect performance and safety. To reduce EMI and improve system reliability, X2 capacitors are widely used in power input and noise suppression circuits.
In this article, we explain what an X2 capacitor is, how it works, and why X2 capacitors are essential in EMI suppression applications.
What Is an X2 Capacitor?
An X2 capacitor is a type of safety film capacitor designed to be connected across the AC power line (Line to Line). It is mainly used to suppress electrical noise and voltage spikes generated by switching devices and external interference.
X2 capacitors are typically manufactured using metallized polypropylene (MPP) film, offering stable electrical performance and reliab...
