MLCC controlled ESR capacitor

Controlled ESR Capacitors: Should You Use Them for Power Integrity? I can’t think of a single product I’ve built that doesn’t require capacitors. We often talk a lot about effective series inductance (ESL) in capacitors and its effects on power integrity. What about effective series resistance (ESR)? Is there a technique you can use to determine the appropriate level of resistance, and can you use ESR to your advantage? Like many answers to important engineering questions, the answer is “it depends.” One type of Read Article

Ferrite Core Selection and Design Decisions

Ferrite Core Selection and Design Decisions When designing a transformer or using a ferrite core inductor, you must use the correct design process, and there is no substitution for real-world final testing. Let’s look at the process. Read Article

Ceramic Capacitors Maximum Voltage and Derating

Ceramic Capacitors Maximum Voltage and Derating Operating just about any type of capacitor below its maximum rated voltage ensures a longer operating life. Such components’ performance will degrade in response to the application of voltages approaching their rated limit and exposure to high temperatures. By choosing to limit the applied voltage, such effects can be reduced. Ceramic capacitors are one of the most common types of capacitors that are in use today thanks to their compact packaging Read Article

Resistor Derating to Improve Mean Time Between Failure

Resistor Derating to Improve Mean Time Between Failure All resistors have a specified power rating that determines the maximum energy they can convert without its performance degrading or the component failing. Read now to learn more. Read Article

Methods of Circuit Protection

Methods of Circuit Protection Overvoltage, overcurrent, and heat are the three most likely events that can destroy our expensive silicon-based components or reduce our product’s life expectancy. The effects are often quite instant, but our product might survive several months of chronic overstress before giving up the ghost in some cases. Without adequate protection, our circuit can be vulnerable to damage, so what should we do? Or do we need to do anything? For instance, if Read Article
