B82794C2475N465

Overview

The B82794C2475N465 is a surface-mount common mode choke manufactured by EPCOS, part of the TDK Electronics portfolio. This component features an inductance of 4.7 mH with a tolerance of 30%. It supports a maximum DC current rating of 300 mA and exhibits a typical DC resistance (DCR) of 900 mOhm. The device is rated for 80 V DC and 42 V AC. Designed for compact electronic assemblies, it provides effective noise suppression in signal lines.

Feature Summary

• Provides common mode noise filtering for differential signal lines
• Utilizes a compact surface-mount package design for automated assembly
• Constructed with ferrite core technology for high impedance at noise frequencies

Applications

• High-speed data interface protection
• Signal line noise suppression in consumer electronics
• EMI reduction in industrial control systems

Procurement Notes

Verify the complete ordering code including the suffix N465 to ensure correct packaging and specifications. Confirm that the 300 mA current rating meets the operational requirements of the target circuit. Check for RoHS compliance status if required by specific manufacturing standards. Ensure compatibility with standard SMD reflow soldering profiles during production integration.

Selection Notes

Select this component when a 4.7 mH inductance value is required for common mode interference suppression. The 300 mA current limit dictates suitability for low-power signal applications rather than power transmission. Consider the 900 mOhm DCR impact on signal integrity and voltage drop. Evaluate the physical dimensions against available PCB real estate constraints.

Part Context

This component belongs to the EPCOS B82794 series of common mode chokes. The series is characterized by small form factors suitable for dense PCB layouts. EPCOS components are widely integrated into automotive, industrial, and consumer electronic devices to ensure electromagnetic compatibility and reliable signal transmission.

Replacement Considerations

Cross-reference with other 4.7 mH common mode chokes from TDK or competitors. Verify pinout compatibility and mechanical footprint alignment before substitution. Ensure equivalent current ratings and impedance characteristics to maintain circuit performance.
