Overview
The B82722A2501N001 is a current-compensated ring core double choke manufactured by EPCOS (TDK). It features a ferrite core and rectangular construction with four radial terminals. The component has a nominal inductance of 27,000 µH at 10 kHz and a maximum DC resistance of 1.2 Ω. It supports a rated voltage of 250 V AC and operates within a temperature range of -40 °C to +125 °C. The physical dimensions are 22.7 mm in length, 22.3 mm in width, and 13.3 mm in height.
Feature Summary
- Current-compensated design for power line filtering
- Ferrite core construction for electromagnetic interference suppression
- Radial leaded termination for through-hole mounting
Applications
- Power line chokes
- Common mode noise filtering
- Electromagnetic compatibility circuits
Procurement Notes
Verify the specific suffix N001 against the manufacturer's latest datasheet to confirm terminal plating and RoHS compliance status. Ensure the selected variant matches the required inductance tolerance and current rating for the target application circuit. Cross-reference the package dimensions with the PCB footprint to guarantee mechanical fit during assembly.
Selection Notes
Select this component for applications requiring common mode suppression in 250 V AC environments. The 27 mH inductance value is suitable for standard power line filtering tasks. Consider the 1.2 Ω DC resistance when calculating voltage drop and thermal performance. Verify that the operating temperature range meets the environmental requirements of the end device.
Part Context
This part belongs to the B82722 series of current-compensated ring core double chokes from EPCOS. These components are designed for general-purpose power line filtering. The series offers various inductance values to suit different noise suppression needs while maintaining a compact rectangular form factor suitable for space-constrained electronic assemblies.
Replacement Considerations
Consult official substitution lists for equivalent current-compensated chokes with matching 27 mH inductance and 250 V AC rating. Verify that any alternative part maintains the same radial lead configuration and similar physical envelope dimensions to ensure compatibility with existing board layouts.
