Procurement Notes

Verify component status carefully as this part is listed as obsolete or discontinued in multiple distributor databases. Confirm availability through secondary market channels or authorized distributors holding remaining stock. Ensure the specific suffix matches design requirements, as ordering suffixes do not alter function but indicate packaging or variant details. Cross-reference datasheets for final electrical validation before integration.

Selection Notes

Select this component when high inductance values are required for low-frequency AC line filtering. The 1.2 A current rating suits moderate power applications. Consider the radial package constraints for board layout. Evaluate thermal performance within the specified -25°C to +105°C operating range. Compare against newer series if long-term supply stability is critical for production.
