Overview
The B82502WC10 is a common mode choke from the EPCOS (TDK) B82502W series, designed for power line filtering. It features an I-core construction with two lines and a through-hole mounting type. Key electrical parameters include an inductance of 680 µH, a rated current of 2 A, and a typical DC resistance (DCR) of 550 mOhm. The component operates within a temperature range of -40°C to +125°C and is rated for 500 V AC / 600 V DC.
Feature Summary
- Provides common mode noise suppression for differential signal lines
- Utilizes robust I-core magnetic structure for stable performance
- Designed for chassis or panel mounting applications
Applications
- Power line input filtering
- EMI suppression in industrial equipment
- Noise reduction in AC/DC converter inputs
Procurement Notes
Verify the specific ordering suffix and package variant against the official TDK-EPCOS datasheet, as part numbers may vary by manufacturing batch or regional specification. Confirm RoHS compliance status directly with the supplier, as some sources indicate varying compliance levels for this series. Ensure the procurement channel provides original manufacturer documentation to guarantee authenticity and traceability.
Selection Notes
Select this component when a 680 µH inductance at 2 A is required for common mode interference mitigation. Consider the physical dimensions and chassis mounting requirements during PCB layout. Verify that the operating voltage does not exceed the 500 V AC rating and that the ambient temperature remains within the specified -40°C to +125°C range for reliable operation.
Part Context
This component belongs to the B82502W series of power line chokes manufactured by EPCOS, now part of the TDK Group. These components are engineered for high reliability in demanding environments. The series typically offers various inductance values and current ratings to suit different power supply filtering needs across automotive, industrial, and consumer electronics sectors.
Replacement Considerations
Check for direct substitutes within the B82502W series with matching inductance and current ratings. Verify pin compatibility and mechanical footprint before replacing. Note that some distributors list this part as obsolete; confirm availability and lead times with authorized TDK-EPCOS partners.
