Line filters are designed to replace discontinued Murata Components
Premier Magnetics announces the in-stock availability of its PMCU Series of common mode line filters designed for switching power supply applications. Offered in both standard winding (for higher efficiency) and sectional winding (for improved high-frequency performance), the PMCU line models provide a direct cross for over three dozen PLA10ANxxx and PLA10ASxxx EMIFIL series components recently […]
Power-supply noise, Part 2
Part 1 looked at the basics of noise, especially concerning power supplies. There are two noise sources which are not as obvious to many engineers as noise that results from the switching action of the power supply: differential mode noise and common-mode noise. These two noise modes have different causes and thus different solutions Q: […]
Power-supply noise, Part 1
“Noise”—perhaps nothing worries design engineers as much as the implications of this single five-letter word. There are good reasons for this worry. Noise is often unpredictable; may come from internal and somewhat controllable sources, or external impossible-to-control sources; it can affect performance accuracy and consistency; it can cause products to not meet their target design […]
