Overview
The B82725J2103N021 is a current-compensated ring core double choke manufactured by EPCOS (TDK). It features a ferrite core and rectangular construction designed for through-hole PCB mounting. Key electrical parameters include a nominal inductance of 2500 µH at 10 kHz, a maximum current rating of 10 A, and a typical DC resistance of 0.015 Ω. The component supports a 250 V AC voltage rating and operates within a temperature range of -40 °C to +125 °C. Physical dimensions are approximately 40.4 mm in length, 21.5 mm in width, and 40 mm in height.
Feature Summary
- Utilizes a current-compensated ring core design for effective common mode noise suppression.
- Constructed with a ferrite core and rectangular housing for robust mechanical stability.
- Engineered for high-current applications with a 10 A rating and low DC resistance.
Applications
- Power line filtering in industrial equipment
- EMI suppression in power supply inputs
- Common mode noise reduction in general purpose electronic circuits
Procurement Notes
Verify the manufacturer designation as EPCOS or TDK Electronics on official datasheets. Confirm the specific suffix N021 matches the required lead length and termination specifications. Ensure the 250V AC rating and 10A current capacity align with the target circuit requirements before procurement.
Selection Notes
Select this component when high current handling capability is required alongside significant inductance for power line filtering. The through-hole package and rectangular form factor suit applications where board space allows for larger components. Verify that the operating temperature range meets the environmental conditions of the final assembly.
