Overview
The B82725V2103U040 is a current-compensated ring core double choke manufactured by EPCOS (TDK). It features a nominal inductance of 5 mH and supports a maximum DC current of 11.5 A with a maximum DC resistance of 8.2 mOhms. Rated for 250 V AC, this component operates within a temperature range of -40°C to +125°C. It utilizes a vertical, 4-pin through-hole package measuring 39.00 mm in length and 23.00 mm in width.
Feature Summary
- Current-compensated ring core design for effective common mode noise suppression
- High thermal stability supporting operation up to 125°C
- Robust construction rated for 250 V AC power line applications
Applications
- Power line filtering in industrial equipment
- EMI suppression in consumer electronics
- Input stage filtering for AC power supplies
Procurement Notes
Verify the specific suffix U040 against official TDK documentation to confirm packaging details and exact electrical tolerances. Ensure the procurement channel provides original manufacturer certification to guarantee component authenticity and traceability. Cross-reference the datasheet revision date to ensure compliance with current environmental standards such as RoHS.
Selection Notes
Select this component when a 5 mH inductance value is required for dual-line power filtering. The 11.5 A current rating suits high-power applications where low insertion loss is critical. Consider the vertical mounting profile for PCB layout constraints and verify that the operating environment remains within the specified -40°C to +125°C temperature range.
Part Context
This part belongs to the B82725 series of power line chokes from EPCOS (TDK). The series offers various inductance and current ratings tailored for different power line filtering requirements. These components are designed for robust performance in demanding electronic environments, providing reliable electromagnetic interference reduction for sensitive circuits.
Replacement Considerations
Consult official TDK substitution guides for compatible alternatives within the B82725 family. Verify that any substitute matches the 5 mH inductance, 11.5 A current rating, and 250 V AC voltage specifications. Ensure physical dimensions and pin configurations remain compatible with existing board layouts.
