Procurement Notes
Verify the specific suffix 'A8' against the official EPCOS datasheet to confirm pinout and tolerance specifications. Ensure the procurement channel provides original manufacturer documentation to validate RoHS compliance and authenticity. Cross-reference the part number with TDK Electronics catalogs to avoid confusion with similar series components.
Selection Notes
Select this component when a robust I-core choke is required for high-current power line applications. The 1.2 mH inductance and 8 A rating make it suitable for filtering noise in systems operating up to 500 V AC. Consider the physical dimensions and mounting requirements to ensure compatibility with the target chassis or PCB layout constraints.
Part Context
This component belongs to the B82505W series of power line chokes manufactured by EPCOS (TDK). The series covers a wide range of inductances and currents, utilizing I-core technology for efficient magnetic field containment. These chokes are engineered for reliability in harsh electrical environments, providing stable performance across varying load conditions.
Replacement Considerations
Consult the official EPCOS replacement guide for direct equivalents. Verify that any substitute maintains the same inductance, current rating, and voltage withstand capabilities. Ensure the alternative component matches the physical footprint and mounting style to facilitate seamless integration without redesigning the enclosure.
