B82725S2133N040

Overview

The B82725S2133N040 is a current-compensated ring core double choke designed for power line applications. It features a rated voltage of 250 V AC at 50/60 Hz and supports a rated current of 1 A. The inductance value is 1.2 mH, with a maximum DC resistance of 120 mOhm per line. The component operates within a temperature range of -40°C to +125°C and withstands a test voltage of 1500 V AC or 2100 V DC for two seconds. It utilizes a through-hole mounting style.

Feature Summary

• Current-compensated ring core design effectively suppresses common-mode interferences while maintaining differential signal integrity.
• Robust construction ensures reliable performance in high-temperature environments up to 125°C.
• Dual-line configuration provides balanced filtering for power supply inputs.

Applications

• Frequency converters
• Switch-mode power applications
• Suppression of common-mode interferences

Procurement Notes

Verify the specific ordering suffix against official TDK documentation to ensure correct packaging and tolerance specifications. Confirm that the rated current and inductance values align with the target circuit requirements before finalizing procurement orders. Cross-reference the material data sheet for compliance details.

Selection Notes

Select this component when common-mode noise suppression is required in power lines operating at 250 V AC. Ensure the application current does not exceed the 1 A rated limit. Consider the physical dimensions and through-hole mounting constraints during PCB layout design to accommodate the ring core structure.

Part Context

This part belongs to the B82725 series of power line chokes manufactured by EPCOS, now part of TDK Electronics. The series focuses on electromagnetic compatibility solutions for industrial and consumer electronics. These components are engineered to meet stringent safety standards for power line filtering.

Replacement Considerations

Consult official TDK substitution lists for verified alternatives. Generic equivalents may not match the current-compensated ring core characteristics or thermal ratings. Verify pinout and dimensional compatibility if considering cross-brand replacements.
