B82720S2301N042

Overview

The B82720S2301N042 is a current-compensated ring core double choke from the EPCOS B82720S series, designed for power line applications. It features a surface mount package with dimensions of 14.20mm L x 14.20mm W and a maximum height of 10.70mm (0.421 inches). The component provides an inductance of 22mH with a rated DC current of 300mA and a DC resistance of 1.5 Ohms. It operates within a temperature range of -40°C to +125°C and supports a rated AC voltage of 250V.

Feature Summary

• Current-compensated ring core design ensures symmetrical interference suppression with approximately 1% stray inductance.
• High resonance frequency achieved through specialized winding techniques.
• Surface mount construction facilitates automated assembly processes.

Applications

• Suppression of common-mode interferences in electronic circuits
• Compact switch-mode power applications
• Power supply input filtering

Procurement Notes

Verify the specific suffix N042 confirms the surface mount variant and 22mH inductance value. Confirm RoHS compliance status via the official datasheet before integration. Ensure PCB footprint matches the 14.20mm x 14.20mm outline. Validate thermal management requirements for operation up to 125°C ambient or self-heating conditions.

Selection Notes

Select this component when surface mount technology is required for common mode noise reduction in power lines. Compare against the B82720K series if vertical through-hole mounting is preferred for similar electrical characteristics. Ensure the 300mA current rating meets the circuit's continuous load requirements without saturation.

Part Context

This part belongs to the B82720A/K/S family of current-compensated ring core chokes manufactured by EPCOS (TDK). These components are engineered for high efficiency in suppressing electromagnetic interference on power lines while maintaining low stray inductance for balanced signal integrity.

Replacement Considerations

The B82720K2301N042 offers identical electrical specifications but utilizes vertical through-hole mounting instead of surface mount. Verify mechanical clearance and soldering process compatibility when substituting between the S (surface) and K (vertical) series variants.
