Overview
The B82720S2202N040 is a current-compensated ring core double choke manufactured by EPCOS (TDK). It features a ferrite core and LCP housing, designed for surface-mount technology. Key electrical parameters include a nominal inductance of 1100 µH per winding, a maximum rated current of 2 A, and a typical DC resistance of 65 mΩ. The component operates within a temperature range of -40 °C to +125 °C and complies with RoHS standards.
Feature Summary
- High resonance frequency achieved through specialized winding techniques
- Approximately 1% stray inductance enabling symmetrical interference suppression
- Suitable for wave soldering processes
- Design compliance with EN 60938-2 (VDE 0565-2) standards
Applications
- Suppression of common-mode interferences
- Compact electronic ballasts in lamps
- Compact switch-mode power applications
Procurement Notes
Verify the specific suffix N40 against official EPCOS documentation to confirm package dimensions and material specifications. Ensure compatibility with surface-mount assembly processes. Cross-reference datasheet revisions to validate thermal performance ratings and impedance characteristics for your specific circuit design requirements.
Selection Notes
Select this component for circuits requiring high-current handling up to 2 A with low DC resistance. The SMD form factor supports automated assembly. Evaluate the 1100 µH inductance value against noise filtering requirements. Confirm that the operating temperature range meets environmental conditions.
Part Context
This part belongs to the B82720S series of power line chokes from EPCOS. These components are engineered for electromagnetic compatibility in compact electronic devices. The series utilizes ring core technology to minimize size while maintaining effective noise suppression capabilities for power lines.
Replacement Considerations
Consult official TDK/EPCOS substitution guides for verified alternatives. Generic equivalents may not match the specific stray inductance or mounting profile.
