Overview
The RV8540-40-S02 is a vertical through-hole common mode choke from the RV8540 series, manufactured by TE Connectivity / Schaffner. It features a MnZn core and is designed for EV charging applications. Key electrical parameters include a DC current rating of 40 A, an inductance of 0.3 mH (300 µH), and a maximum DC resistance of 1.4 mΩ. The component operates within a temperature range of -40°C to +125°C and has physical dimensions of approximately 65.5 mm in height.
Feature Summary
- Utilizes MnZn core material for effective electromagnetic interference suppression
- Designed as a current compensated choke for vertical PCB mounting
- Optimized for high-current electric vehicle charging infrastructure
Applications
- Electric Vehicle (EV) Charging Systems
- Power Line Filtering in High Current Applications
- Industrial Power Supply EMC Compliance
Procurement Notes
Verify the specific inductance value against official datasheets, as sources vary between 220 µH and 300 µH for this part number. Confirm the manufacturer designation as TE Connectivity / Schaffner. Ensure the voltage ratings (AC 530V, DC 1000V) align with your system requirements before procurement.
Selection Notes
Select this component when a 40 A current rating and vertical mounting are required for EV charging modules. Compare the 0.3 mH inductance against circuit noise specifications. Consider the MnZn core characteristics for frequency response needs. Verify compatibility with the 1.4 mΩ DC resistance limit for thermal management.
Part Context
This component belongs to the RV8540 series of common mode chokes, which are specialized for high-current applications. The series includes variants with different current ratings and inductance values, such as the RV8540-32-S02 and RV8540-50-S02, allowing for scalable design solutions in power electronics.
Replacement Considerations
Check for direct substitutes within the RV8540 series, such as RV8540-32-S02 or RV8540-50-S02, if current ratings differ. Verify pinout and mechanical dimensions for any cross-brand replacements to ensure PCB compatibility.
