Overview
The B85321A2945A301 is a feedthrough capacitor from the EPCOS - TDK Electronics B85321 series, designed as an electromagnetic interference (EMI) filter. It features a rated voltage of 250 V AC at 50/60 Hz and 600 V DC. The component supports a rated current of 300 A, referenced to a 40 °C rated temperature. This passive component serves as a high-current EMI suppression device for power line applications.
Feature Summary
- Provides electromagnetic interference suppression through feedthrough capacitor architecture
- Supports high continuous current handling capabilities for power line integration
- Rated for operation under specified AC and DC voltage conditions
Applications
- Power line EMI filtering in industrial equipment
- Electromagnetic compatibility enhancement in high-current systems
- Feedthrough filtering for electronic enclosures
Procurement Notes
Verify the specific datasheet version for the B85321A2945A301 to confirm mechanical dimensions and terminal configurations. Ensure that the operating environment does not exceed the 40 °C reference temperature without applying appropriate current derating factors. Confirm compliance with RoHS3 standards if required by your manufacturing specifications.
Selection Notes
Select this component when high current capacity is required alongside EMI suppression. The 300 A rating distinguishes it from lower-capacity filters. Verify that the 250 V AC / 600 V DC ratings align with the system's electrical requirements. Consider thermal management strategies to maintain performance within the rated temperature limits during continuous operation.
Part Context
This component belongs to the B85321 series of feedthrough components manufactured by TDK Electronics AG, formerly known as EPCOS. The series includes various models with different current and voltage ratings. TDK Electronics continues to produce these filters under its unified brand identity following the global renaming of EPCOS entities.
Replacement Considerations
Consult the official B85321 series documentation for alternative part numbers with matching current and voltage ratings. Ensure any substitute maintains the same feedthrough capacitor topology and physical mounting requirements for direct replacement.
