B82720H0015A035

Overview

The B82720H0015A035 is a current-compensated ring core double choke designed for signal line filtering. It features two lines with an inductance of 68 mH at 10 kHz and a rated current of 200 mA. The component has a typical DC resistance of 3.3 Ohms and supports a rated voltage of 42 V AC (50/60 Hz) or 80 V DC. It utilizes through-hole mounting with dimensions of 0.512 inches by 0.374 inches and operates within a temperature range of -40°C to 125°C.

Feature Summary

• Current-compensated ring core construction for effective common mode noise suppression
• Dual-line configuration optimized for differential signal integrity preservation
• High inductance value suitable for low-frequency interference attenuation

Applications

• Signal line filtering in noise-sensitive electronic systems
• Common mode noise suppression in communication interfaces
• Protection of data transmission lines against electromagnetic interference

Procurement Notes

Verify the specific suffix A035 to confirm the 68 mH inductance and 200 mA rating, as the B82720H series contains variants with different electrical characteristics. Ensure the ordering documentation explicitly states the 42 V AC / 80 V DC voltage ratings. Confirm that the through-hole package dimensions match the design footprint requirements before finalizing procurement.

Selection Notes

Select this component when high inductance is required for signal lines rather than power lines. The 200 mA current rating limits its use to low-current data applications. Verify that the operating temperature range meets the environmental conditions of the target application. Consider the physical size constraints relative to other available common mode chokes in the same series.

Part Context

This part belongs to the B82720H series of signal line common mode chokes manufactured by EPCOS, now part of TDK Electronics. The series focuses on protecting sensitive signal paths from common mode noise. Unlike power line chokes, these are designed for lower current applications with higher inductance values to maintain signal quality in noisy environments.

Replacement Considerations

Check datasheets for alternative parts within the B82720H series that share the same 68 mH inductance and 200 mA current rating. Verify pin compatibility and mechanical dimensions for direct replacement. Ensure the substitute component meets the same voltage and temperature specifications.
