B82790C0113N201

Overview

The B82790C0113N201 is a surface-mount common-mode choke from the EPCOS B82790 series, designed for data and signal line filtering. It features a current-compensated ring core construction with two lines. Key electrical parameters include an inductance of 11 µH, a maximum rated current of 500 mA, and a DC resistance of 80 mΩ. The component supports a rated voltage of 42 V AC or 80 V DC and operates within a temperature range of -40°C to +125°C. It meets AEC-Q200 automotive qualification standards and is housed in a compact horizontal package measuring 7.10 mm x 6.00 mm.

Feature Summary

• Current-compensated ring core design for effective common-mode noise suppression
• Automotive-grade reliability compliant with AEC-Q200 standards
• Surface-mount configuration optimized for automated assembly processes

Applications

• Automotive infotainment and communication bus protection
• Data interface line filtering in industrial control systems
• Signal integrity enhancement in high-speed digital circuits

Procurement Notes

Verify the complete part number including tolerance suffixes against official TDK-EPCOS documentation to ensure exact specification matching. Confirm that the required inductance and current ratings align with the specific circuit design constraints before procurement. Ensure storage conditions comply with moisture sensitivity levels if applicable.

Selection Notes

Select this component when automotive-grade durability and compact form factor are required for signal line filtering. The 11 µH inductance and 500 mA current rating suit moderate-speed data interfaces. Consider the 80 mΩ DC resistance impact on signal attenuation during initial circuit simulation phases.

Part Context

This component belongs to the B82790 series of common-mode chokes manufactured by EPCOS, now operating as TDK Electronics. The series specializes in surface-mount filters for protecting sensitive electronic circuits against electromagnetic interference in demanding environments.

Replacement Considerations

Cross-reference with other B82790 series variants such as B82790C0113N265 for similar specifications. Verify pin compatibility and mechanical dimensions before substituting with components from different manufacturers.
