Alongside capacitors, inductors are essential components in RF and microwave applications. Ceramic core inductors provide stable inductance values, ensuring consistent performance across a broad frequency range. These qualities make them ideal for applications where low loss and high efficiency at high frequency are critical.

In an AC/DC converter, power factor correction (PFC) circuits are required to ensure the input current is in phase with and proportional to the input voltage, improving power quality and efficiency. But the high-frequency switching that occurs in the PFC circuit can generate significant electromagnetic interference (EMI).

Electronic devices power our world and allow us to communicate. In all applications requiring signal integrity and accurate power amplification, blocking capacitors are used to provide clean waveforms and correctly amplified voltages.

As engineers embed receivers for Global Navigation Satellite Systems (GNSS), like GPS and Galileo, into systems ranging from autonomous vehicles to precision agriculture, the RF environment is becoming more crowded, and it’s more difficult to maintain signal integrity.

As discussed in the first post in our safety capacitor series, safety capacitors are designed to help safeguard users and equipment from electrical hazards, even in the event of failure.

Improving overall system performance starts with foundational component selections. Growing demand for high-energy, reliable and compact converters in electric vehicles (EVs) and other industrial and energy applications is encouraging development in components like multilayer ceramic capacitors (MLCCs).

Pharmaceutical manufacturing is becoming increasingly reliant on robotics and automation. From precise dispensing and high-speed sorting to kit assembly and sterile packaging, today’s automation tasks demand advanced motor and drive technology to keep pace with complex, high-reliability environments.

Unplanned power interruptions and shutdowns pose serious risks for industrial facilities. Even a few seconds of lost control can result in equipment damage, safety hazards, or production losses. Fail-safe systems are among the key risk mitigation techniques used in high-stakes industrial environments.

In our prior blog, What Are Safety Capacitors, we provided an overview safety capacitor functionality and how these passive components play a crucial role filtering EMI in a circuit. Now, we will dive deeper into the functions of safety capacitors and how to select the capacitor that will meet all your needs by exploring the different classes and subclasses for these components.

With deep expertise in advanced miniaturization, Knowles delivers capabilities including micro electromagnetic sensor coiling, micro molding, micro stamping, precision machining, micro-electronics integration, and compact high-density assemblies.

Multilayer ceramic capacitors (MLCCs) are made up of two materials—ceramic dielectric material and metal electrode material.

Safety capacitors are passive electronic components designed to mitigate the effects of transient voltages and interference in electrical circuits.
