• Ferrite core material providing stable magnetic properties across the operating temperature range

Common Mode Chokes Applications

• Suppression of electromagnetic interference (EMI) in data lines
• Noise filtering in signal transmission circuits
• Protection of sensitive electronic components from common mode noise

Common Mode Chokes Procurement Notes

Verify the specific suffix 'BE' versus 'AE' when sourcing, as packaging or minor mechanical variations may exist between distributors. Confirm RoHS compliance status directly with the manufacturer or authorized supplier documentation. Ensure the selected vendor provides valid traceability records for quality assurance purposes. Cross-reference the datasheet revision date to ensure compatibility with current design requirements.

Common Mode Chokes Selection Notes

Select this component for applications requiring compact surface mount solutions for data line protection. The 500 mA current rating suits low-power signal processing circuits. Consider the 300 mΩ DCR impact on signal integrity if voltage drop is critical. The wide operating temperature range allows use in industrial environments without additional thermal management.
