FN2030B-4-06

Overview

The Schaffner FN2030B-4-06 is a single-phase, single-stage EMI/RFI power line filter designed for chassis mounting. It features a rated current of 4 A and a voltage rating of 250 VAC. The unit utilizes fast-on terminals for connection and operates within a frequency range of 0 Hz to 400 Hz. Key electrical parameters include a leakage current of 2 µA, an inductance of 8 mH, and a capacitance of 470 nF. Physical dimensions are 85 mm in length, 54 mm in width, and 40.3 mm in height, with a maximum operating temperature of +100°C.

Feature Summary

• Provides high attenuation performance for EMC/RFI suppression in single-phase applications
• Designed for medical equipment usage with ultra-low leakage current specifications
• Utilizes a compact chassis mount form factor with quick-connect terminal interfaces

Applications

• Medical electronic equipment requiring strict leakage current limits
• Industrial control systems operating at 50/60 Hz or 400 Hz
• Single-phase AC/DC power supply input filtering

Procurement Notes

Verify the specific suffix 'B' indicates the low-leakage variant suitable for medical standards. Confirm that the fast-on terminal pitch matches the mating connector requirements. Ensure the chassis mounting hole pattern aligns with the enclosure design. Check for required safety certifications such as UL, CSA, and IEC/EN compliance for the target market. Validate thermal management capabilities given the 100°C maximum operating temperature rating.

Selection Notes

Select this component when a single-stage filter is sufficient for noise reduction requirements. Choose based on the 4 A current rating and 250 VAC voltage compatibility. Consider the low leakage current specification if patient safety isolation is critical. Evaluate the physical footprint constraints against the 85x54x40.3 mm dimensions. Ensure the fast-on termination style fits the available wiring harness or PCB layout.

Part Context

This part belongs to the Schaffner FN2030 series of general-purpose AC/DC EMC filters. The series offers various current ratings from 1 A to 30 A with different terminal options. The 'B' designation typically denotes specialized variants, such as those optimized for medical applications with reduced leakage. The series is widely used in industrial and commercial power conditioning.

Replacement Considerations

Direct substitutes include other FN2030 series variants with matching 4 A ratings and fast-on terminals, such as FN2030-4-06, provided leakage current requirements are met. Verify that any replacement maintains the same 250 VAC rating and chassis mounting dimensions.
