Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct inductance and tolerance specifications. Confirm that the package style and pin configuration match the target PCB layout requirements. Check for any recent updates to the RoHS compliance status or material declarations. Ensure the selected variant meets the required thermal performance standards for the intended operating environment.

Selection Notes

Select this component when high common-mode rejection is required for low-current signal lines. The 100mA rating suits applications with minimal DC bias current. Consider the physical dimensions and mounting orientation constraints during the mechanical design phase. Verify that the inductance value provides adequate attenuation for the specific interference frequencies present in the system.

Part Context

This part belongs to the B82791 series of data and signal line chokes from EPCOS (TDK Electronics). The series offers various inductance values ranging from 2.2 mH to 47 mH. These components are engineered for robust performance in industrial and consumer electronics environments requiring reliable electromagnetic interference suppression.

Replacement Considerations

Cross-reference with other B82791 variants having identical electrical parameters. Verify compatibility of the mounting footprint and terminal configuration. Ensure substitute parts meet the same voltage and current ratings.
