Procurement Notes

Verify component status carefully as this specific part number may be discontinued or obsolete. Confirm availability through authorized distributors or TE Connectivity channels. Request updated substitution recommendations if the original model is no longer manufactured. Ensure replacement components meet identical electrical ratings and mechanical mounting requirements for seamless integration into existing designs.

Selection Notes

Select this filter for applications requiring 16 A capacity and 480 VAC rating. Consider the single-stage configuration for standard EMI reduction needs. Evaluate thermal constraints within the -25°C to 100°C operating range. Verify that chassis mounting capabilities align with the enclosure design. Assess leakage current limits against regulatory standards for the target market.
