Overview
The B82732R2501B30 is a current-compensated frame core double choke manufactured by EPCOS (TDK). It features a closed magnetic circuit with a ferrite frame construction and a PET coil former rated UL94 V-0. The component utilizes a 4-section winding directly on the core for efficient electromagnetic interference suppression. Designed for power line applications, it operates at a rated voltage of 250 V AC. The inductance is specified as 30 mH with a maximum DC current rating of 0.5 A.
Feature Summary
- Current-compensated frame core design for effective common mode noise reduction
- Closed magnetic circuit utilizing ferrite frame construction
- PET coil former with UL94 V-0 flame retardant rating
- Four-section winding applied directly to the core structure
Applications
- Power line chokes for AC mains filtering
- Common mode interference suppression in electronic equipment
- EMI filtering in devices operating at 250 V AC
Procurement Notes
Verify the specific suffix 'B30' against official EPCOS documentation to confirm pin configuration and packaging details. Ensure the application environment does not exceed the rated 250 V AC or 0.5 A DC current limits. Cross-reference the manufacturer's latest datasheet for any updates to the B82732R series specifications before finalizing procurement.
Selection Notes
Select this component when a current-compensated choke is required for differential mode noise suppression in single-phase AC circuits. The 30 mH inductance value suits applications needing moderate impedance at lower frequencies. Verify that the physical dimensions of the frame core fit the available PCB space and that the radial termination style matches the assembly requirements.
Part Context
This part belongs to the B82732R series of fixed inductors from EPCOS (TDK). The series comprises various current-compensated frame core double chokes designed for power line applications. These components are characterized by their robust ferrite construction and direct winding techniques, offering reliable performance in industrial and consumer electronics environments requiring EMI mitigation.
Replacement Considerations
Consult the official B82732R series datasheet for confirmed substitute part numbers within the same family. Ensure any replacement maintains the 30 mH inductance, 0.5 A current rating, and 250 V AC voltage rating. Verify mechanical compatibility and terminal configuration before substituting.
