SFSW hermetic EMI filters deliver reliable noise suppression and signal integrity in harsh, high-frequency environments.

Considering the complexities of routing and signal integrity, it’s more and more common to see multilayer printed circuit board (PCB) designs where radio frequencies (RF) or digital traces cross on different layers of the stack.

Smoothing capacitors reduce voltage ripple during AC-to-DC conversion, helping deliver stable, efficient power in EV charging systems.

Supercapacitors, also known as electric double-layer capacitors (EDLCs), store energy electrostatically rather than via chemical reactions like traditional batteries. Their unique characteristics make them ideal for applications requiring short bursts of power and/or durability over time.

One of the fundamental roles of capacitors is charging and discharging energy predictably. Many electronics applications leverage capacitors to store energy and release it in a controlled pulse of current or voltage.

At the most basic level, high-power amplifiers (HPAs) take signals from the waveform generator and increase the signal level to a higher power.

Supercapacitors feature unique characteristics that set them apart from traditional batteries in energy storage applications. Unlike batteries, which store energy through chemical reactions, supercapacitors store energy electrostatically, enabling rapid charge/discharge cycles.

Low-noise amplifiers (LNAs) in radio frequency (RF) receivers are designed to amplify low-amplitude signals (i.e., less than -100 dBm) from an antenna without decreasing their signal-to-noise ratio (SNR).

Choosing capacitors with low resistance can help prevent overheating and improve performance in demanding electronic systems.

Effective defibrillator design relies on high-reliability capacitors that deliver controlled electrical energy while supporting compact, dependable systems.

Electrical arcing can cause any number of issues in a circuit that lead to unreliable operation. Without effective snubbing, arcing is associated with early failures in relays, switch contacts and solid-state components (e.g., SCRs and TRIACs).

When it comes to aerospace and defense applications, every single component plays a role in the success and longevity of the system. Capacitors are vital in flight control systems, radar systems, signal intelligence equipment and more.
