Ceramic Capacitors Maximum Voltage and Derating Ceramic Capacitors Maximum Voltage and Derating Operating just about any capacitor below its maximum rated voltage ensures a longer operating life. A capacitor's 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, those degradation effects can be reduced. Ceramic capacitors are one of the most common types of capacitors that are in use today thanks to their compact Read Article
Resistor Derating to Improve Mean Time Between Failure Resistor Power 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.

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

External Power Supply Efficiency Ratings Efficiency Standards and Ratings for External Power Supplies A power supply’s efficiency is simply the ratio between the energy it consumes and the energy it supplies. No device can be perfectly efficient; there will always be losses in heat or electromagnetic fields. The leading causes come from active component losses (MOSFET and diode switching losses) and, to a lesser extent, from passive component losses (resistors, capacitors, and inductor impedance losses). It moves towards utilizing higher Read Article
