Overview
The Schaffner FN2520-25-08-C1111 is a single-phase EMC/EMI line filter designed for chassis mounting. It supports an input voltage of up to 277VAC and 400VDC, with a rated current of 25A at +40°C. The unit utilizes a low-profile 1U rack-mount form factor and through-hole terminals. This component provides high attenuation performance for general-purpose filtering requirements in electronic systems.
Feature Summary
- Space-saving 1U rack-mount design suitable for limited access areas
- High attenuation performance for effective noise suppression
- Robust construction supporting both AC and DC voltage inputs
Applications
- Robotics systems
- Data center infrastructure
- Power supplies and battery chargers
Procurement Notes
Verify the specific part number suffix against official Schaffner documentation to confirm terminal type and current rating. Ensure compatibility with existing chassis mounting standards. Confirm voltage ratings match system requirements before integration. Cross-reference datasheet specifications for thermal derating curves.
Selection Notes
Select this model for applications requiring a compact single-phase filter with 25A capacity. Consider the 1U height constraint when designing enclosure layouts. Evaluate attenuation requirements against standard EMI limits. Verify that through-hole mounting aligns with PCB or chassis assembly processes.
Part Context
This component belongs to the FN2520 series of high-performance EMC/EMI IEC filters. The series is characterized by its low-profile design and suitability for demanding industrial environments. It complements other Schaffner solutions like the FN9280 series for comprehensive power integrity management.
Replacement Considerations
Consult official substitution guides for equivalent models within the FN2520 series. Verify mechanical dimensions and pinout compatibility before replacing existing units. Ensure electrical ratings meet or exceed original specifications.
