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).

In an ideal world, capacitors could be designed in a way where they would exhibit no resistance. However, this is physically impossible to achieve as there will always be some type of internal resistance in a capacitor that appears in series with the capacitance of the device.

Defibrillators are designed to deliver electric current to the heart, in the form of a controlled shock to the myocardium, to treat arrhythmias and restore the heartbeat back to normal.

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.

As consumers demand rapid, and accurate, delivery of online orders, yet labor shortages continue to prevail, distributors need to increase efficiency and productivity, reduce errors, and improve inventory management in their warehouses.

The types of threats facing radar systems are continuing to diversify. To adapt, the industry is evolving toward fully digital arrays that can support a variety of mission profiles.

As power conversion systems evolve to leverage higher voltages and wide bandgap semiconductors like silicon carbide (SiC) and gallium nitride (GaN), system designers face new challenges in managing the electromagnetic interference (EMI) frequency landscape.

Monolithic microwave integrated circuit (MMIC) amplifiers are widely used in defense radar systems. The industry recognizes them as a compact, high-performance option that’s reliable and easy to integrate.

Radio frequency (RF) and microwave applications involve the transmission and receipt of high-frequency electromagnetic signals.

DC link capacitors are commonly used in power converters as an intermediary buffer between an input source to an output load that have different instantaneous power, voltages, and frequencies. In electric vehicle (EV) applications, DC link capacitors help offset the effects of inductance in inverters, motor controllers, and battery systems.

Battery energy storage systems (BESS) are named for their function. They capture, accumulate, and store energy in rechargeable batteries to be discharged later. Industrial facilities, homes, electric vehicles (EVs) and the like rely on these systems for backup power and operational efficiency.
