How Ceramic Capacitor Assemblies Improve Efficiency In Power And RF Applications

Knowles’ ceramic capacitor assemblies are engineered to enhance performance in power electronics and radio frequency (RF) applications through the use of stacked configurations and advanced dielectric materials. These assemblies offer improved stability, efficiency, and compactness—key factors in modern electronic system design.

In power electronics, ceramic capacitor assemblies outperform traditional aluminum and tantalum alternatives by delivering high capacitance density, effective filtering, and voltage smoothing. Commonly used in switch-mode power supplies, converters, and inverters, these assemblies reduce ripple, stabilize voltage, and provide robust bulk decoupling. Their high capacitance-to-volume ratio, achieved through vertical stacking of X7R capacitors, makes them ideal for power-dense applications such as avionics and electric vehicles.

In RF systems, where minimal signal loss and high-frequency performance are critical, capacitor assemblies offer low equivalent series resistance (ESR) and inductance (ESL). Using Class I dielectrics like C0G/NP0, these components ensure stable capacitance across temperature and frequency ranges. They are essential in RF power amplifiers, voltage-controlled oscillators, impedance matching networks, and plasma/RF heating systems. Their high Q factor and low-loss performance support efficient signal transfer and energy conservation.

Across both application areas, Knowles’ capacitor assemblies provide compact, high-performance solutions. Additionally, customization options are available to meet specific electrical and reliability requirements. As a MIL-qualified provider, Knowles supports mission-critical systems with assemblies designed for long-term stability and failure prevention.
