Contact UsAMOBEADS™ and SPIKE KILLER Noise Suppression Devices
Our AMOBEADS™ and SPIKE KILLER noise inhibitor parts are amorphous magnetic parts with a high magnetic permeability. They have a stronger noise inhibiting effect than CR snubbers and ferrite beads, making them ideal for high-frequency regulation. AMOBEADS™ is particularly useful for situations in which immediate measures against noise are required, as it can be directly placed onto MOSFET and diode leads with no machining of the circuit board required. Our range also includes Spike killer, which has an even stronger noise inhibiting effect than AMOBEADS™.

Features
- Low coercivity, providing greater noise inhibiting effect
- Outstanding saturation potential, minimizing adverse effects on other parts
- Easy noise inhibiting - simply pass through the lead section of a semiconductor (AMOBEADS™)
- AMOBEADS™ range includes type with lead and SMD type
- Low-priced DY series available for customers who purchase 10kp or higher
