Overview
The RV8540-25-S16 is a current-compensated common mode choke from the RV8540 series, manufactured by TE Connectivity / Schaffner. It utilizes a MnZn core material and features four lines with vertical mounting for PCB installation via through-hole termination. The component has an inductance of 170 µH and supports a maximum DC current of 25 A. Its maximum DC resistance is specified at 0.3 mOhms. Designed for EV charging applications, it operates within a temperature range of -40°C to +125°C.
Feature Summary
- Current-compensated design utilizing MnZn core material
- Four-line configuration for vertical PCB mounting
- Optimized for electric vehicle charging systems
Applications
- EV Charging infrastructure
- Power electronics filtering
- EMC suppression in high-current circuits
Procurement Notes
Verify the specific datasheet version (DM or CM) as electrical characteristics may vary between designations. Confirm that the 170 µH inductance and 25 A current rating align with your circuit requirements. Ensure the through-hole footprint matches your PCB layout. Check RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component when high current handling up to 25 A is required alongside significant common mode noise reduction. The MnZn core offers distinct frequency response characteristics compared to nanocrystalline alternatives. Consider the vertical form factor for space-constrained PCB designs where height is less critical than footprint area.
Part Context
This part belongs to the RV8540 series of common mode chokes. It shares the series designation with variants like RV8540-16-S16 and RV8540-32-S16, which differ primarily in current ratings and inductance values. The series is characterized by its use in high-power density applications requiring robust EMI suppression.
Replacement Considerations
Direct substitutes include other RV8540 series parts such as RV8540-16-S16 or RV8540-32-S16, provided their current and inductance specifications meet the system needs. Cross-referencing with similar MnZn current-compensated chokes from other manufacturers requires careful verification of pinout and thermal performance.
