FERROXCUBE Ferrites for Interference Suppression and Electromagnetic Compatibility (EMC)
With the ever increasing intensive use of electronic equipment Electromagnetic Compatibility (EMC) has become an important item. Laws specify limits of the level of interference caused by equipment (EME) and also the sesitivity of equipment to incoming interference (EMS).
Ferroxcube offer a full range of products and cores dedicated to EMI-suppression applications!

Properties

• Specialized materials for well defined frequency-ranges < 30 MHz; 30 MHz ... 1 GHz
• Beads available as standard series for SMD and Beads on wire
• Widebandchokes from multi-hole beads with little stray field in SMD and through hole versions
• Cable shields have all shapes from round tubes to rectangular sleeves

Benefit

• High effective suppression with small components
• Smaller, lighter and more integrated electronic devices
• Can be handled by automatic placement machines
• No EMI comming from the component itself
• Cover a broad range of existing cables and wires with standards
