B82799S513N1

Overview

The B82799S513N1 is a surface-mount common mode choke manufactured by EPCOS, part of the TDK Electronics portfolio. Designed for data and signal line applications, this component features a ring core construction with ferrite material. It provides an inductance of 51 µH at 100 kHz and supports a maximum DC current of 200 mA. The typical DC resistance is 250 mOhms. The device operates within a temperature range of -40°C to +125°C and is packaged in a compact 1812 (4532 metric) footprint, measuring 4.5 mm in length.

Feature Summary

• Provides effective common mode noise suppression for differential data lines
• Utilizes a robust ferrite ring core structure for stable magnetic performance
• Complies with AEC-Q200 automotive qualification standards for reliability

Applications

• Automotive infotainment system data buses
• Industrial control network signal lines
• Consumer electronics high-speed interface protection

Procurement Notes

Verify the specific ordering suffix against official TDK documentation to confirm exact electrical tolerances and packaging specifications. Ensure the procurement channel sources genuine components from authorized distributors to guarantee compliance with RoHS directives and AEC-Q200 automotive grade requirements. Cross-reference the manufacturer's latest datasheet for any updates on lead times or package variations.

Selection Notes

Select this component when designing circuits requiring common mode filtering for low-current signal lines in space-constrained environments. The 200 mA current rating suits data transmission interfaces rather than power delivery paths. Consider the 1812 package dimensions for PCB layout compatibility and verify that the 51 µH inductance value aligns with the target frequency spectrum for noise attenuation in the specific application design.

Part Context

This component belongs to the B82799 series of common mode chokes produced by EPCOS, now integrated into TDK Electronics' passive component lineup. The series is engineered for suppressing electromagnetic interference in digital communication channels. As part of the broader TDK portfolio, these components support global supply chains for automotive, industrial, and consumer electronic markets requiring certified passive filtering solutions.

Replacement Considerations

Consult official TDK cross-reference lists for verified substitutes. Generic equivalents may not match the AEC-Q200 qualification or precise inductance tolerance required for automotive data bus applications.
