The component features a two-stage configuration and utilizes quick connect terminals for input and output connections. Key electrical parameters include an inductance of 32.18mH. It is certified by CSA, UR, and VDE agencies.

Feature Summary

• Provides high attenuation of radio frequency interference (RFI) noise
• Features a low-profile design suitable for space-constrained applications
• Utilizes capacitive input for maximum filter performance
• Designed with minimal leakage current characteristics

Applications

• Medical equipment power supplies
• General purpose electronic devices requiring EMI suppression
• Chassis-mounted power entry modules

Procurement Notes

Verify the specific ordering suffix to ensure correct termination style and certification requirements. Confirm that the 250VAC rating and 3A current capacity align with the system's operational limits. Check for RoHS3 compliance status if required by project specifications. Ensure chassis mounting dimensions match the enclosure design before procurement.

Selection Notes

Select this component when a single-phase, two-stage filter is required for 50/60Hz applications. The 3A rating and 250VAC specification define the electrical boundaries. Consider the quick connect termination type for assembly compatibility. Verify that the chassis mount style fits the available panel space and thermal environment constraints.
