B82722A2801N020

Overview

The B82722A2801N020 is a current-compensated ring core double choke manufactured by EPCOS (TDK). It features a rated inductance of 27 mH and a rated current of 800 mA. The component is designed for 250 V AC applications and utilizes a through-hole mounting style. Its physical dimensions are approximately 22.70 mm in length, 22.30 mm in width, and 13.30 mm in height.

Feature Summary

• Current-compensated ring core design for power line filtering
• Dual-line configuration for common mode noise suppression
• Through-hole termination for secure board mounting

Applications

• Power line chokes
• Common mode filters
• EMI suppression in AC power inputs

Procurement Notes

Verify the specific suffix N020 against the manufacturer's latest datasheet to confirm exact dimensional tolerances and terminal plating specifications. Ensure the 27 mH inductance value aligns with the target circuit requirements for the intended frequency range. Cross-reference the 800 mA rated current with the actual operating load to prevent saturation.

Selection Notes

Select this component when a high-inductance common mode choke is required for low-current AC power lines. The 27 mH value provides significant attenuation for high-frequency noise. Consider the 250 V AC rating for standard mains applications. The through-hole package is suitable for environments requiring robust mechanical stability.

Part Context

This part belongs to the B82722 series of power line chokes from EPCOS (TDK). The series includes various inductance values and current ratings tailored for different power supply filtering needs. These components are widely used in industrial and consumer electronics to meet electromagnetic compatibility standards.

Replacement Considerations

Check for direct substitutes within the B82722 series that match the 27 mH inductance and 800 mA current rating. Verify that any alternative maintains the same 250 V AC voltage rating and through-hole footprint dimensions to ensure mechanical compatibility.
