B82789C0104N002

Overview

The B82789C0104N002 is a surface-mount data line filter manufactured by EPCOS, part of the TDK Group. It functions as a common-mode choke designed for signal and data lines. The component features a rated DC voltage of 80 V and an AC voltage rating of 42 V. It supports a maximum DC current of 150 mA with a maximum DC resistance of 1.5 Ohms. The device operates within a temperature range of -55°C to +85°C or +110°C depending on specific application conditions.

Feature Summary

• Provides common-mode filtering for data and signal lines to suppress electromagnetic interference.
• Designed for surface-mount installation in compact electronic assemblies.
• Constructed to withstand high test voltages between lines for robust insulation.

Applications

• Protection of USB interfaces against common-mode noise.
• Filtering in high-speed data transmission circuits.
• Signal integrity enhancement in consumer electronics communication ports.

Procurement Notes

Verify the exact suffix 'N002' against official TDK Electronics documentation to confirm the specific tolerance and tape-and-reel packaging configuration. Ensure the selected variant matches the required operating temperature range of +85°C or +110°C for your specific design constraints before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring common-mode suppression for low-voltage data lines. Consider the 1.5 Ohm DC resistance impact on signal attenuation and ensure the 150 mA current rating exceeds the peak operational current of the protected line to prevent saturation or overheating during normal use.

Part Context

This component belongs to the B82789 series of data and signal line chokes from EPCOS (TDK). These components are engineered for applications where space is limited but effective noise suppression is critical. The series utilizes advanced materials to maintain performance across wide temperature ranges while supporting high-frequency signal integrity.

Replacement Considerations

Consult official TDK cross-reference lists for verified substitutes. Generic equivalents may not match the precise impedance characteristics or voltage ratings required for certified signal line protection.
