B82614R2172A030

Overview

The B82614R2172A030 is a power line choke from the EPCOS sine-wave choke series, designed for AC applications with a rated voltage of 250 V. It features an air-gapped rectangular ferrite core and a closed polycarbonate coil former compliant with UL 94 V-0 standards. The component operates without encapsulation to ensure recyclability and RoHS compatibility. Key electrical parameters include a rated current range of 0.8 A to 2.7 A and a rated inductance range of 0.5 mH to 3.0 mH. The design utilizes a four-section winding to achieve high resonance frequency and minimize saturation effects.

Feature Summary

• High resonance frequency achieved through specialized four-section winding construction
• Low saturation effects resulting from the use of an air-gapped core
• Suitable for wave soldering processes and compliant with EN 60938-2 design standards

Applications

• Switch-mode power supplies utilizing current pump topologies
• Output filtering in switch-mode power applications
• Reduction of harmonics and Power Factor Correction (PFC) circuits

Procurement Notes

Verify the specific inductance value and tolerance against the suffix code on the datasheet, as the base series covers a wide range. Confirm that the non-encapsulated construction aligns with your environmental protection requirements. Ensure the operating temperature range meets system specifications. Cross-reference the terminal configuration with your PCB layout constraints before finalizing the order.

Selection Notes

Select this component when designing filters for switch-mode power supplies requiring high resonance frequencies. The air-gapped core makes it suitable for applications prone to saturation. Consider the lack of encapsulation if conformal coating is not part of the assembly process. Verify that the physical dimensions fit within the designated space on the printed circuit board.

Part Context

This component belongs to the B82614 series of sine-wave chokes manufactured by EPCOS, now part of the TDK Group. The series is engineered for power line applications, offering robust performance in filtering tasks. The manufacturer emphasizes recyclability by omitting encapsulation materials, distinguishing these chokes from fully potted alternatives in the same category.

Replacement Considerations

Consult official substitution lists for direct equivalents. Verify that any alternative maintains the same core material properties and winding structure to preserve the high resonance frequency characteristic.
