CTX210409-R

Overview

The CTX210409-R is a surface-mount CCFL transformer manufactured by Eaton Electronics. It is designed for cold cathode fluorescent lamp applications with a power rating of 4W. The component operates at an output voltage of 13V and provides a current of 7mA. Key electrical specifications include an inductance of 20uH and a DC resistance of 0.16 ohms. The device functions within a temperature range of 0°C to +70°C.

Feature Summary

• Designed specifically for driving cold cathode fluorescent lamps (CCFL) in surface-mount configurations.

Applications

• CCFL backlighting systems
• Display panel illumination

Procurement Notes

This component is officially discontinued and no longer manufactured by Eaton Electronics. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm that the units are genuine, factory-sealed, and free from damage, as availability is limited and supply chain verification is critical due to the end-of-life status.

Selection Notes

Engineers replacing this part should identify alternatives based on matching electrical parameters: 4W power rating, 13V output, 7mA current, and 20uH inductance. Surface-mount package compatibility and operating temperature range alignment are essential. Since the original part is discontinued, cross-referencing datasheets for functional equivalents from other manufacturers is necessary to ensure circuit performance remains unchanged.

Part Context

The CTX210409-R belongs to Eaton's Electronics Division line of passive components, specifically transformers intended for display technology. It is part of a series including variants like CTX210407-R and CTX210411-R, which differ primarily in output voltage specifications while maintaining similar power and form-factor characteristics for standardized CCFL driver designs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the part is discontinued, engineers must manually verify equivalent transformers from other manufacturers based on the specified 4W, 13V, 7mA, and 20uH parameters.
