B82725J2202N020

Overview

The B82725J2202N020 is a current-compensated ring core double choke from the EPCOS B82725A series, designed for power line filtering. It features an inductance of 18 mH per line and supports a rated current of 2.0 A. The component utilizes a horizontal through-hole mounting style with dimensions of 44.00 mm x 42.40 mm x 25.00 mm. It operates within a temperature range of -40°C to +125°C and is rated for 250 V AC applications.

Feature Summary

• Current-compensated ring core design for effective common mode noise suppression
• Dual-line configuration suitable for differential and common mode interference reduction
• Robust construction supporting high thermal stability up to 125°C

Applications

• Power line filtering in industrial electronics
• EMI suppression in consumer appliances
• Data processing equipment input stages

Procurement Notes

Verify the specific suffix N020 against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure compatibility with existing PCB footprints given the 44.00 mm x 42.40 mm dimensions. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the 2.0 A rating with your circuit's peak load requirements to prevent saturation.

Selection Notes

Select this component when high inductance (18 mH) is required for low-frequency noise attenuation in 250 V AC systems. The 2.0 A current rating makes it suitable for moderate power applications. Consider the radial through-hole package for mechanical stability in environments with vibration. Compare against the broader B82725A series if different current or inductance values are needed.

Part Context

This part belongs to the EPCOS B82725A series of power line chokes. These components are engineered for current-compensated operation, minimizing magnetic field leakage. The series offers various inductance and current combinations, all sharing a similar ring core architecture. EPCOS, now part of TDK, manufactures these for reliable performance in demanding electronic environments.

Replacement Considerations

Check for direct substitutes within the B82725A series with matching 18 mH and 2.0 A ratings. Verify that any alternative maintains the same 250 V AC voltage rating and horizontal mounting orientation. Ensure the replacement supports the -40°C to +125°C operating temperature range.
