• Data line protection circuits

Procurement Notes

Verify the specific part number suffix against official TDK-EPCOS documentation to confirm exact electrical characteristics and packaging details. Ensure compatibility with wave soldering processes if required by the assembly line. Confirm that the 42 V AC / 80 V DC voltage ratings align with the target circuit requirements before procurement.

Selection Notes

Select this component for applications requiring common mode noise suppression on low-voltage data lines. The 47 mH inductance and 100 mA current rating define its operational limits. Consider the through-hole package type for mechanical stability and verify that the operating temperature range meets the environmental conditions of the final assembly.

Part Context

This component belongs to the B82791 series of common mode chokes manufactured by EPCOS, now part of TDK Electronics. The series is characterized by compact ring core designs intended for protecting sensitive data and signal lines against electromagnetic interference. These components are widely used in industrial and consumer electronics where reliable signal integrity is critical.

Replacement Considerations

Consult official TDK-EPCOS substitution guides for verified alternatives. Cross-reference inductance, current rating, and physical dimensions when evaluating potential substitutes to ensure functional equivalence in the target application.
