For EMI filtering and noise attenuation, California-based Johanson Dielectrics is offering a range of novel multi-layer ceramic devices that combines two balanced shunt capacitors with mutual ...

According to the IEEE Standard Dictionary of Electrical and Electronic Terms, power factor (PF) is defined as the ratio of the circuit power (watts) to the circuit volt-amperes. This is described by ...

The input stage of an off-line power converter usually contains an LC averaging filter. A common practice is to damp the LC filter using additional reactive/dissipative components. In this article, we ...

In today's world of increasing electrical noise, higher-speed logic, and more-sensitive circuits, the need for high-frequency noise filtering is especially critical. Noise can enter a circuit through ...

A large majority of EMI problems, including both emissions and immunity, involve interference currents conducted into and out of the box via a power or data cable. These currents can be controlled by ...

Last month, we discussed low power factor and how resonance can disrupt facility operations. This month, we'll talk about harmonic filter design and various system parameters that affect filter ...
