Overview
The RV8540-25-S12 is a vertical board-mount EMC choke from the Schaffner RV-Series. It features a MnZn core and supports four lines with a current rating of 25 A and an inductance of 0.5 mH. Rated for 530 VDC, it utilizes PCB terminals for connection. The component operates within a temperature range defined by UL 94V-0 flammability standards and carries PD2 pollution degree classification.
Feature Summary
- Vertical board-mount configuration for space-efficient integration
- Four-line common mode filtering capability using MnZn core technology
- PCB terminal termination for direct circuit board installation
Applications
- Power supply input filtering
- Industrial equipment EMI suppression
- General purpose EMC mitigation
Procurement Notes
Verify the specific suffix code against the manufacturer's latest documentation to ensure correct pinout and mechanical dimensions. Confirm that the 25 A current rating aligns with your thermal management design. Check for any recent packaging changes or RoHS compliance updates in the official datasheet before finalizing procurement orders.
Selection Notes
Select this component when a vertical mounting style is required for high-current applications up to 25 A. Ensure the PCB layout accommodates the vertical profile and the specified terminal spacing. Verify that the 530 VDC voltage rating meets the system's maximum operating voltage requirements under all conditions.
Part Context
This part belongs to the Schaffner RV-Series, which specializes in common mode chokes for electromagnetic compatibility. The series offers various current ratings and inductance values tailored for different power line filtering needs. The RV8540 variant specifically addresses higher current demands with robust construction.
Replacement Considerations
Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement maintains the same vertical form factor, 25 A rating, and 0.5 mH inductance to preserve circuit performance and mechanical fit.
