B82732F2451B001

Overview

The B82732F2451B001 is a current-compensated frame core double choke designed for single-phase EMI suppression in AC power lines. It operates at rated voltages of 250 V AC (50/60 Hz) with a maximum rated current of 450 mA. The component provides a rated inductance of 100 mH and features a typical DC resistance of 2.93 Ohms. Constructed for through-hole mounting, it measures 24.5 mm x 14.5 mm x 13.5 mm. The device supports an operating temperature range from -40 °C to +125 °C, including self-temperature rise.

Feature Summary

• High inductance combined with low resistance for efficient signal integrity
• Approximately 2% stray inductance enabling symmetrical interference suppression
• High pulse-handling capability suitable for demanding power line environments

Applications

• Single-phase AC power line filtering
• EMI suppression in electronic equipment input stages
• Common mode noise reduction in consumer electronics

Procurement Notes

Verify the complete part number suffix to confirm specific inductance and current ratings, as the B82732F series encompasses multiple variants. Ensure the selected component matches the required 250 V AC rating and 450 mA current capacity for the target circuit. Confirm through-hole package compatibility with the printed circuit board layout. Check RoHS compliance status if required by regional regulations.

Selection Notes

Select this component when high inductance is required for effective common mode noise attenuation in single-phase applications. The low stray inductance makes it suitable for circuits requiring symmetrical interference suppression. Consider the 450 mA current limit and thermal performance within the -40 °C to +125 °C range during design integration. Verify that the physical dimensions fit the available PCB space.

Part Context

This component belongs to the B82732F series of current-compensated frame core double chokes manufactured by EPCOS, now part of the TDK Group. These chokes are engineered for power line applications where compact size and high performance are necessary. The series utilizes a frame core construction to achieve high inductance values while maintaining low resistance characteristics.

Replacement Considerations

Direct substitutes within the same series include B82732F2101B001 (10 mH) and B82732F2601B001 (60 mH), provided their electrical ratings match the application requirements. Cross-referencing datasheets is essential to ensure equivalent inductance, current handling, and physical dimensions before substitution.
