CTX210403-R

Overview

The CTX210403-R is a specialty transformer manufactured by Eaton - Electronics Division, designed for surface mount applications. It features an inductance of 44 µH and is specifically intended for use with CCFL power supplies. The component has a maximum installed height of 5.50 mm (0.217 inches) and measures 0.650 inches in length by 0.827 inches in width. The part status is listed as obsolete.

Feature Summary

• Specialty transformer design optimized for CCFL power supply circuits
• Surface mount construction for automated PCB assembly
• Compact physical profile suitable for space-constrained layouts

Applications

• CCFL power supplies
• Cold cathode fluorescent lamp drivers
• Display backlighting systems

Procurement Notes

Verify component availability through authorized distributors, noting the obsolete status which may limit new production orders. Confirm mechanical dimensions and electrical specifications against current design requirements before integration. Check for end-of-life notifications or last-time-buy windows from the manufacturer to ensure long-term supply chain stability for existing products.

Selection Notes

Select this component only if the application specifically requires a 44 µH inductance for CCFL driving. Evaluate the surface mount footprint compatibility with the target PCB layout. Consider that the obsolete status necessitates careful lifecycle management and potential redesign planning for future iterations.

Part Context

This part belongs to the specialty transformers category within Eaton's electronics division portfolio. It is distinct from general-purpose power inductors like the DR1040 series, serving niche lighting applications rather than generic DC-DC conversion tasks.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the obsolete status. Designers should consult Eaton directly for cross-reference recommendations or consider redesigning with currently active components.
