PLY17BN7820R7A2B

Common Mode Chokes Overview

The PLY17BN7820R7A2B is a two-line common mode choke manufactured by Murata Electronics, designed for through-hole mounting on printed circuit boards. It features radial termination style and provides an inductance of 7.8 mH with a maximum DC current rating of 700 mA. This component serves as a filter choke to suppress electromagnetic interference in electronic circuits.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression via dual-line filtering architecture
• Designed for reliable through-hole PCB integration using radial leads

Common Mode Chokes Applications

• Electromagnetic interference suppression in signal lines
• Power supply input filtering for low-current applications
• Data line protection in industrial control systems

Common Mode Chokes Procurement Notes

Verify the specific suffix A2B against official Murata documentation to confirm exact electrical tolerances and material specifications. Confirm availability status as distribution sources may indicate end-of-life or limited stock conditions. Ensure the through-hole package dimensions match the target PCB footprint before procurement.

Common Mode Chokes Selection Notes

Select this component when a 7.8 mH inductance value is required for common mode noise reduction in circuits operating at currents up to 700 mA. The through-hole radial form factor is suitable for applications requiring mechanical robustness over surface mount alternatives. Verify that the core saturation characteristics align with the peak current demands of the specific application environment.

Common Mode Chokes Part Context

This part belongs to Murata's passive component portfolio, specifically within the common mode choke category. It is engineered for general-purpose filtering tasks where standard inductance values and moderate current handling are sufficient. The product line emphasizes reliability and consistent performance across varying environmental conditions.

Common Mode Chokes Replacement Considerations

Check for direct substitutes with identical 7.8 mH inductance and 700 mA current ratings. Ensure replacement parts maintain the same through-hole radial package dimensions to fit existing PCB layouts without modification.
