B82733V2112B001

Overview

The B82733V2112B001 is a current-compensated frame core double choke designed for power line applications. It features a vertical design with four pins for through-hole mounting. The component operates at a rated voltage of 500 V AC and supports a maximum rated current of 1.1 A at +40 °C. It provides a rated inductance of 47 mH measured at 10 kHz, with a typical DC resistance of 804 milliohms. The unit functions within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Current-compensated frame core construction with closed magnetic circuit
• Vertical PCB mounting configuration with four leads
• High insulation clearance and creepage distances exceeding 3 mm
• Certified for international safety standards including UL, VDE, and ENEC

Applications

• Power line filtering in household appliances
• EMI suppression in industrial automation equipment
• Noise reduction in renewable energy systems
• Input stage filtering in motor drive units

Procurement Notes

Verify the specific suffix code to ensure correct packaging and tolerance specifications. Confirm that the 500 V AC rating aligns with your system's electrical requirements. Check for RoHS compliance status if environmental regulations apply. Ensure the vertical form factor fits within the designated PCB footprint constraints. Validate certification marks against regional regulatory needs before finalizing orders.

Selection Notes

Select this component when high common-mode noise attenuation is required in space-constrained vertical layouts. The 47 mH inductance offers effective filtering for standard power line frequencies. The 1.1 A current rating suits moderate power applications. Consider the operating temperature range for environments subject to thermal fluctuations. Verify pin spacing matches existing board designs to avoid mechanical interference.

Part Context

This part belongs to the B82733 series of power line chokes manufactured by TDK Electronics, formerly EPCOS. The series utilizes ferrite frame cores and PET coil formers for robust performance. These components are engineered for electromagnetic compatibility in AC power circuits. The vertical design optimizes board space utilization compared to horizontal alternatives.

Replacement Considerations

Triad Magnetics CMF23V-473111 is documented as a substitute option. Verify inductance, current rating, and physical dimensions match before substitution.
