B82791G0014A016

Overview

The B82791G0014A016 is a current-compensated ring core double choke designed for data and signal line applications. It features a ferrite core and a polycarbonate case rated UL 94 V-0. The component has a rated inductance of 4.7 mH at 10 kHz, with a maximum DC resistance of 850 mOhm. It supports a rated AC voltage of 42 V and a DC voltage of 80 V, handling a rated current of 100 mA. Dimensions are 17.50 mm x 17.50 mm x 8.00 mm max.

Feature Summary

• Current-compensated ring core construction for effective common-mode interference suppression
• Vertical or horizontal mounting options suitable for wave soldering processes
• RoHS-compatible design utilizing a flame-retardant polycarbonate housing

Applications

• Suppression of asymmetrical interference coupled in data lines
• Signal line filtering in industrial equipment
• Noise reduction in consumer electronics communication interfaces

Procurement Notes

Verify the specific inductance tolerance and DC resistance values against the official EPCOS/TDK datasheet prior to procurement. Confirm that the polycarbonate case material meets the required UL 94 V-0 flammability rating for the target application environment. Ensure compatibility with wave soldering processes if vertical or horizontal mounting is specified for the assembly line.

Selection Notes

Select this component when common-mode noise suppression is required for low-current data lines operating up to 100 mA. The 4.7 mH inductance provides adequate attenuation for standard signal frequencies. Verify that the 42 V AC / 80 V DC voltage ratings align with the system's electrical requirements. Consider the physical dimensions and lead configuration for PCB layout constraints.

Part Context

This part belongs to the B82791G series of data and signal line chokes manufactured by EPCOS, now part of TDK Electronics. The series utilizes ferrite cores within polycarbonate cases to provide robust electromagnetic interference protection. These components are engineered for through-hole mounting and are widely used in environments requiring reliable signal integrity maintenance.

Replacement Considerations

Check for direct substitutes within the B82791G family with matching inductance and current ratings. Verify mechanical footprint compatibility before considering alternative manufacturers. Ensure any replacement maintains the same UL 94 V-0 rating and RoHS compliance status.
