• EMI suppression in equipment operating at 250 V AC
• Noise reduction in circuits requiring current-compensated double chokes

Procurement Notes

Verify the specific suffix against official TDK/EPCOS documentation to confirm exact electrical tolerances and packaging details. Ensure the procurement source provides valid certification marks such as UR or VDE if required for end-product compliance. Cross-reference the part number with the latest datasheet to confirm availability of RoHS compliance information and specific manufacturing dates.

Selection Notes

Select this component when a fixed inductance of 10 mH is required for power line applications with currents up to 2.3 A. The high DC resistance of 85 Ohms must be considered in circuit design to ensure appropriate voltage drop characteristics. Verify that the 250 V AC rating aligns with the system's operational voltage requirements and that the through-hole mounting style fits the PCB layout constraints.

Part Context

This component belongs to the B82733 series of fixed inductors, specifically designed as power line chokes. The series offers various inductance values ranging from 10 to 100 mH and current ratings from 0.7 to 2.3 A. Manufactured by EPCOS, now part of TDK Electronics, these chokes are engineered for robust performance in industrial and consumer electronic applications requiring reliable electromagnetic interference suppression.

Replacement Considerations

Check for B82733V2232B001 which shares similar physical dimensions but may differ in voltage rating (300 V AC) and DC resistance (188 mOhm). Verify compatibility with the B82733F2112B1 series if different inductance or current ratings are acceptable. Always consult official substitution guides to ensure electrical parameters meet safety standards.
