B82790S0513N201

Overview

The B82790S0513N201 is a signal line common mode choke manufactured by EPCOS, part of TDK Electronics. Designed for surface mount applications, this component features a current-compensated ring core construction with double windings to effectively suppress electromagnetic interference on data and signal lines. It provides an inductance of 51 µH at 100 kHz with a maximum DC resistance of 140 mΩ. The device supports a rated current of 500 mA and withstands voltages up to 80 V DC or 42 V AC. Housed in a compact 7.10 mm x 6.00 mm package with J-leads, it operates reliably within a temperature range of -40°C to +125°C.

Feature Summary

• Utilizes current-compensated ring core construction with double windings for effective noise suppression.
• Designed specifically for filtering signal and data lines in electronic circuits.
• Features a robust surface mount package suitable for automated assembly processes.

Applications

• Filtering noise on high-speed data transmission lines
• EMI suppression in communication equipment interfaces
• Signal integrity protection in industrial control systems

Procurement Notes

Verify the specific manufacturer source when ordering, as components may be sourced from TDK Electronics or its subsidiary EPCOS. Confirm that the received parts match the exact model number B82790S0513N201 to ensure correct electrical specifications. Check for any manufacturing date codes relevant to your supply chain requirements. Ensure packaging matches standard reel quantities if required for SMD placement. Validate authenticity through official distributor channels to avoid counterfeit components.

Selection Notes

Select this component when designing circuits requiring common mode noise reduction on differential signal lines. The 51 µH inductance value is suitable for frequencies around 100 kHz. Ensure the PCB footprint accommodates the 7.10 mm x 6.00 mm dimensions and J-lead configuration. Verify that the operating current does not exceed 500 mA to prevent saturation. Consider the thermal performance within the -40°C to +125°C range for your specific environment.

Part Context

This component belongs to the B82790 series of common mode chokes from EPCOS/TDK. It is engineered for signal line protection rather than power line filtering. The series offers various inductance and current ratings to suit different bandwidth and load requirements. It represents a standard solution for EMI compliance in digital communication interfaces.

Replacement Considerations

Direct substitutes include other 51 µH, 500 mA common mode chokes in similar SMD packages from TDK/EPCOS. Verify pin compatibility and mechanical height constraints before swapping. Cross-reference with B82793 series variants if higher current ratings are acceptable, though inductance values must match precisely for circuit functionality.
