Noise suppression devices Amobeads®, Spike killers®

Outline Noise suppression devices are magnetic parts that mitigate abrupt changes in current and voltage to suppress noise. Conventional noise reducers, noise filters for example, aim to absorb generated noise. Our devices suppress the source of noise generation. <New Release> New Design High cost performance AMOBEADS® DY Series is newly released.

Advantages

• Higher noise suppression effect because of low coercive force
• Excels in saturability and hardly affects other parts
• Easily mountable noise suppressor, only threaded by semiconductor leads

Applications

• Switching power supplys
• DC / AD converters
• Control circuits for electric motors
• Automobile-motored actuators
