Overview
The RV8140-32-S01 is a horizontal mount common mode choke from the Schaffner RV series, designed for power line filtering. It features MnZn core technology and supports a maximum DC current of 32 A with an inductance of 0.5 mH (340 µH @ 100 kHz). The component operates within a temperature range of -40°C to +125°C and has a maximum DC resistance of 2.1 mΩ. Rated for 530 VDC, it utilizes radial PCB terminals and meets UL 94V-0 flammability standards.
Feature Summary
- Utilizes MnZn core material for effective electromagnetic interference suppression in four-line configurations.
- Supports high continuous current handling up to 32 A with low insertion loss characteristics.
- Engineered for robust thermal performance across extended industrial operating temperatures.
Applications
- Power supply input filtering
- Industrial equipment EMC compliance
- Data line protection
Procurement Notes
Verify the specific inductance value against official datasheets, as sources indicate variations between 0.3 mH and 0.5 mH. Confirm terminal type compatibility and mounting orientation requirements before integration. Ensure environmental ratings match application constraints.
Selection Notes
Select this component for applications requiring high current capacity and wide temperature stability. Compare inductance specifications carefully against circuit design requirements. Verify physical dimensions and terminal pitch for PCB layout compatibility.
