5500.2221

Overview

The Schurter 5500.2221 is a single-phase, two-stage power line filter designed for EMI suppression in AC power circuits. It features a rated voltage of 125 VAC and 250 VAC with a current rating of 25 A. The unit utilizes a chassis mount installation style with screw termination type. Key electrical parameters include a capacitance (Cx) of 2.2 uF and an inductance of 2 mH. It operates at frequencies of 50 Hz and 60 Hz. The component holds CE, cURus, and UKCA approval agencies certifications.

Feature Summary

• Two-stage filtering configuration for enhanced interference suppression
• Chassis mount design with screw termination for secure integration
• Certified for global compliance including CE, cURus, and UKCA standards

Applications

• General purpose industrial equipment power conditioning
• Single-phase AC power line noise reduction
• Electronic devices requiring EMI/RFI suppression

Procurement Notes

Verify the specific ordering suffix to ensure correct terminal configuration and certification requirements match the target application. Confirm that the 25 A current rating and 250 VAC voltage limits align with the system's operational parameters. Check for any OEM-specific availability restrictions as some variants may be designated exclusively for original equipment manufacturers or EMS design business customers.

Selection Notes

Select this model when a two-stage topology is required for superior attenuation compared to single-stage alternatives. Ensure the chassis mounting style fits the enclosure constraints. Verify that the 2.2 uF capacitance value does not exceed leakage current safety limits for the specific medical or sensitive applications. Compare against the 5500.2222 if higher current capacity is needed.

Part Context

This component belongs to the Schurter FSW series of power line filters. It is part of a broader family of single-phase filters offering various current ratings and stage configurations. The 5500.2221 specifically addresses general-purpose applications requiring robust EMI filtering within standard AC power distribution networks.

Replacement Considerations

The 5500.2222 is a verified substitute within the same series, offering similar two-stage functionality but with a higher current rating of 36 A. Ensure mechanical fitment and terminal compatibility are validated before substitution.
