B82722S0133A020

Overview

The B82722S0133A020 is a surface-mount current-compensated ring core double choke manufactured by EPCOS (TDK). It is designed for power line filtering applications with a rated AC voltage of 48V and DC voltage of 80V. The component provides an inductance of 0.47mH (470µH) and supports a current rating of 13A. Its physical dimensions are 30.99mm in length and 25.40mm in width, utilizing a two-line configuration for effective common mode noise suppression.

Feature Summary

• Current-compensated ring core design for efficient magnetic field cancellation
• Surface-mount packaging for automated assembly integration
• Dual-line configuration for power line noise filtering

Applications

• Power supply input filtering
• DC-DC converter noise suppression
• Electronic equipment EMI mitigation

Procurement Notes

Verify the specific suffix A020 against the manufacturer's official datasheet to confirm the exact inductance tolerance and current rating specifications. Ensure the surface-mount footprint matches the 30.99mm x 25.40mm dimensions provided in the technical documentation before finalizing procurement orders.

Selection Notes

Select this component when a surface-mount solution is required for low-voltage power lines carrying up to 13A. The 48V AC rating makes it suitable for specific low-voltage AC or rectified DC applications where compact filtering is necessary without sacrificing current handling capacity.

Part Context

This part belongs to the B82722S series of current-compensated ring core chokes from EPCOS (TDK). These components are engineered for high-current applications requiring robust common mode noise reduction in a space-constrained surface-mount format, distinct from through-hole alternatives in the broader B8272x family.

Replacement Considerations

Consult official TDK substitution guides for equivalent SMD ring core chokes with matching 13A current ratings and 0.47mH inductance. Verify pin compatibility and thermal performance before substituting with other manufacturers' offerings.
