Overview
The RV8141-32-S03 is a three-phase common mode choke from the Schaffner RV-Series, designed for board mounting via PCB terminals. It supports a rated current of 32 A and a voltage rating of 530 VDC. The inductance is 920 µH at 100 kHz with a DC resistance of 2.7 mOhm. Operating temperatures range from -40°C to +125°C. The component features a horizontal orientation, PD2 pollution degree protection, IP00 ingress protection, and UL 94V-0 flammability rating. Its height is 41.1 mm.
Feature Summary
- Provides common mode noise suppression for three-phase power lines
- Designed for direct PCB terminal mounting with horizontal orientation
- Rated for high thermal stability up to 125°C operation
Applications
- Industrial power supply units
- Three-phase motor drives
- Power conversion systems requiring EMI filtering
Procurement Notes
Verify the specific suffix S03 against the manufacturer's latest datasheet to confirm terminal configuration and pinout compatibility. Ensure the PCB layout accommodates the 41.1 mm height and horizontal mounting style. Confirm that the 32 A current rating and 530 VDC voltage limit align with the system's peak operational requirements before finalizing procurement.
Selection Notes
Select this component when a robust three-phase common mode choke is required for board-mounted applications. The 920 µH inductance offers significant noise attenuation at 100 kHz. Consider the 2.7 mOhm DCR for efficiency calculations in high-current circuits. The wide temperature range makes it suitable for demanding industrial environments where standard components might fail.
Part Context
This part belongs to the Schaffner RV-Series of EMC chokes, which are engineered for electromagnetic interference suppression in power electronics. The series is characterized by high current handling capabilities and compact board-mount designs. The RV8141-32-S03 specifically targets three-phase applications, distinguishing itself from single-phase variants within the broader product family.
Replacement Considerations
Publicly confirmed substitute part numbers for RV8141-32-S03 were not identified in the provided documentation. Verify electrical parameters such as inductance, current rating, and physical dimensions against potential alternatives to ensure functional equivalence.
