B82721K2801U030

Overview

The B82721K2801U030 is a current-compensated ring core double choke designed for power line applications. It features an inductance of 150 µH at 10 kHz and supports a maximum current rating of 800 mA. The component operates within a temperature range of -40°C to +125°C and utilizes a through-hole mounting configuration.

Feature Summary

• Current-compensated ring core construction with ferrite core
• Polycarbonate case with polyurethane potting
• Sector winding technique for high resonance frequency
• Flame-retardant case and potting per UL 94 V-0

Applications

• Power line interference suppression
• Symmetrical interference suppression in electronic circuits

Procurement Notes

Verify the specific ordering suffix U030 against official EPCOS/TDK documentation to confirm packaging details, as suffixes often denote tray quantities or reel specifications. Ensure the voltage rating aligns with system requirements before procurement.

Selection Notes

Select this component for applications requiring common-mode noise reduction on power lines where space constraints favor a compact ring core design. Consider the 800 mA current rating and 150 µH inductance values to ensure compatibility with the target circuit's electrical parameters.

Part Context

This part belongs to the B82721 series of power line chokes manufactured by EPCOS (TDK). The series offers various inductance and current ratings using current-compensated ring core technology, suitable for filtering electromagnetic interference in AC power inputs.

Replacement Considerations

Check for direct substitutes within the B82721 series or compatible B82720 series components that match the 150 µH inductance and 800 mA current rating while maintaining the same footprint and thermal characteristics.
