CTX210659-R

Overview

The CTX210659-R is a discontinued surface-mount CCFL transformer manufactured by Eaton Electronics. It features dual primary windings and a single secondary winding, designed for backlight power applications. Key electrical specifications include a power rating of 2.5W, an output voltage of 1.34kV, and an inductance of 19μH. The device operates at a frequency of 80kHz with a current rating of 5mA and a DC resistance of 190mOhm.

Feature Summary

• Designed specifically for Cold Cathode Fluorescent Lamp (CCFL) backlight power supplies
• Utilizes a dual primary winding configuration for flexible input integration
• Constructed as a surface-mount device (SMD) for automated PCB assembly

Applications

• CCFL backlight inverters for LCD displays
• Industrial monitor backlighting systems
• Medical imaging equipment lighting modules

Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability requires checking distributor surplus or obsolete stock channels. Ensure the specific suffix matches the required pinout and insulation class, as variations may exist within the legacy series. Cross-reference part numbers carefully to confirm compatibility with existing circuit designs before procurement attempts.

Selection Notes

Select this component only if the design supports obsolete parts and requires exact 1.34kV output characteristics. Verify that the 19μH inductance and 80kHz operating frequency align with the existing inverter topology. Consider the physical dimensions and SMD footprint compatibility during the replacement phase. Evaluate long-term supply chain risks associated with discontinued industrial components.

Part Context

The CTX210659-R belongs to the Eaton CCFL transformer series, which provides specialized magnetic components for fluorescent lamp ignition. This model represents a legacy product line from the Electronics Division, previously used in high-reliability display applications. Its discontinuation reflects industry shifts toward LED-based backlighting solutions, making it a niche component for maintenance and repair scenarios.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers must evaluate generic CCFL transformers with matching 1.34kV output and 2.5W power ratings. Verify inductance and DCR values closely to ensure circuit stability.
