Overview
The RV8540-25-S02 is a common mode choke from the RV8540 series, manufactured by TE Connectivity Schaffner. It utilizes MnZn core technology and supports four-line configurations. The component is rated for a maximum DC current of 25 A with a minimum inductance of 0.7 mH. Electrical characteristics include a maximum DC resistance of 3.2 mOhms and a tolerance of 1%. It operates within a temperature range of -40°C to high limits, suitable for horizontal mounting applications.
Feature Summary
- Utilizes MnZn core material for effective common mode noise suppression
- Supports four-line configuration for versatile circuit integration
- Designed for horizontal mounting to optimize board space
Applications
- Power supply input filtering
- Industrial equipment EMI suppression
- Data line protection
Procurement Notes
Verify the specific manufacturer designation, as TE Connectivity acquired Schaffner EMC. Confirm that the part number RV8540-25-S02 matches the required 25A rating and 0.7mH inductance. Ensure compatibility with horizontal mounting requirements and check for updated RoHS compliance documentation under the new corporate structure before finalizing procurement orders.
Selection Notes
Select this component when a robust common mode choke with a 25A current rating is required. The low DC resistance of 3.2 mOhms minimizes power loss. Verify that the MnZn core material meets the frequency response needs of the application. Ensure the physical dimensions accommodate the horizontal mounting style on the target PCB or chassis.
Part Context
This component belongs to the RV8540 series of common mode chokes. The series offers various current ratings and inductance values. The RV8540-25-S02 specifically denotes the 25A variant with standard tolerances. It is part of Schaffner's portfolio now integrated into TE Connectivity's electromagnetic interference solutions.
Replacement Considerations
Check for direct cross-references from TE Connectivity. Evaluate other RV8540 variants if current ratings differ. Consider alternative MnZn common mode chokes with similar 25A ratings and 0.7mH inductance if availability is an issue.
