Overview
The B82614R2102A030 is a power line choke from the B82614 series, manufactured by EPCOS (TDK). It features an air-gapped rectangular ferrite core and a closed polycarbonate coil former rated UL 94 V-0. The component has a rated voltage of 250 V AC and a rated current range of 0.8 to 2.7 A. Its rated inductance spans 0.5 to 3.0 mH. Construction includes a 4-section winding for high resonance frequency and low saturation effects. It is designed without encapsulation, making it recyclable and suitable for wave soldering.
Feature Summary
- High resonance frequency achieved through 4-section winding design
- Low saturation effects resulting from the use of an air-gapped core
- Design complies with EN 60938-2 (VDE 0565-2) standards
- Recyclable construction due to omission of encapsulation and glue
Applications
- Switch-mode power supplies with current pump
- Output filter in switch-mode applications
- Reduction of harmonics and PFC
Procurement Notes
Verify the specific part number suffix against official TDK/EPCOS documentation to confirm exact electrical parameters such as inductance tolerance and DC resistance. Ensure the selected variant matches the required rated current and voltage for the target application. Confirm RoHS compatibility and lead material specifications if required by the assembly process. Cross-reference ordering codes with the latest datasheet revisions to avoid discrepancies in packaging or terminal configurations.
Selection Notes
Select this component based on its suitability for sine-wave chokes in power line applications. Consider the air-gapped core characteristics for managing saturation in current pump circuits. Evaluate the 4-section winding benefits for minimizing parasitic capacitance and increasing resonance frequency. Verify that the polycarbonate former and lack of encapsulation meet thermal and mechanical requirements for wave soldering processes.
Part Context
This component belongs to the B82614 series of power line chokes and sine-wave chokes. The series covers rated currents from 0.8 A to 2.7 A and inductances from 0.5 mH to 3.0 mH at a rated voltage of 250 V AC. These chokes are engineered for efficiency and reliability in electromagnetic interference suppression within switch-mode power systems.
Replacement Considerations
Consult official TDK/EPCOS substitution guides for verified alternative part numbers within the B82614 series or compatible families. Ensure any substitute maintains identical core material, winding structure, and dimensional constraints for PCB mounting.
