B82791H0015A025

Overview

The B82791H0015A025 is a through-hole data line choke manufactured by EPCOS - TDK Electronics. It features a rated inductance of 10 mH at 10 kHz and supports a maximum DC current of 100 mA. The component has a typical DC resistance of 1.2 Ohms and operates within a temperature range of -40 to +125 °C. Rated voltages are specified as 42 V AC and 80 V DC.

Feature Summary

• Current-compensated ring core double choke design
• Ferrite core construction with polycarbonate case
• Suitable for wave soldering processes

Applications

• Suppression of asymmetrical interference coupled in data lines
• Signal line filtering in electronic circuits
• Data and signal line chokes for communication interfaces

Procurement Notes

Verify the specific suffix code against official EPCOS documentation to confirm pin configuration and tolerance. Ensure the ordering part number matches the required inductance value and current rating for the target application. Cross-reference the RoHS compliance status with the latest manufacturer declarations before finalizing procurement orders.

Selection Notes

Select this component when a through-hole common mode choke is required for low-current data lines. The 100 mA rating limits suitability to signal processing rather than power delivery. Verify that the 1.2 Ohm DC resistance does not introduce excessive voltage drop in the specific circuit path during normal operation.

Part Context

This component belongs to the B82791 series of common-mode chokes designed for data and signal lines. The series typically offers inductance values ranging from 2.2 mH to 47 mH with a standard 100 mA current rating. These devices utilize ferrite cores and are intended for suppressing electromagnetic interference in sensitive signal paths.

Replacement Considerations

Check for direct substitutes within the B82791G/H series with identical inductance and current ratings. Verify mechanical footprint compatibility for through-hole mounting if replacing existing board designs.
