Operating in high humidity settings exposes electronic components to severe degradation risks. Moisture leads to corrosion, insulation breakdown and reduced lifespan over time. Expertly engineered components enable reliable performance under these harsh conditions.

In high-voltage, high-reliability applications, safety is non-negotiable, which is why safety capacitors are essential. These passive components are engineered to mitigate the risks associated with transient voltages and electrical interference, helping protect both users and equipment from hazards, even in the event of component failure.

Powering everything from pulsed lasers to experimental fusion reactors, pulsed power systems demand fast, controlled energy delivery. High-performance capacitors are key to this capability. 

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). To prevent this noise from disrupting nearby electronics or violating regulatory limits, EMI filters are essential. This blog post provides a comprehensive guide for selecting the appropriate safety capacitors to perform EMI filtering in the PFC stage of an AC/DC converter.

From EVs and industrial automation to renewable energy and smart logistics, power systems are becoming increasingly complex. As a result, they’re increasingly dependent on reliable, high-speed energy storage too. Enter supercapacitors, a critical technology bridging the gap between traditional batteries and real-time power demands.  

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. When selecting a safety capacitor for your application, you typically have two choices in dielectric material – ceramic and film. To select the right technology for your application, it is important to both understand your requirements and the differences between what each material has to offer.

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.
