CTX210605TR-R

Overview

The CTX210605TR-R is a board-mount power transformer from the CCFL series, manufactured by Eaton Electronics Division. It features a dual primary winding and a single secondary winding configuration. The device has a power rating of 6 VA, with a primary voltage rating of 20 V and a secondary voltage rating of 1.34 kV. Key electrical parameters include an inductance of 44 µH and a DC resistance of 0.16 ohms. The component measures 26 mm in length, 16.5 mm in width, and 7.1 mm in height. It is designed for surface mount (SMD/SMT) installation and is supplied in tape and reel packaging.

Feature Summary

• Dual primary winding architecture for flexible input integration
• Single high-voltage secondary output suitable for CCFL applications
• Surface mount design for automated PCB assembly

Applications

• Cold Cathode Fluorescent Lamp (CCFL) power supplies
• Backlight inverter circuits
• Display illumination systems

Procurement Notes

This component is currently listed as obsolete or end-of-life. Availability is limited to existing stock or surplus channels. Verify manufacturing date codes and physical condition when sourcing from third-party distributors. Ensure compatibility with legacy designs requiring this specific form factor and electrical specification before procurement.

Selection Notes

Select this transformer for designs requiring a 6 VA rating with 20 V primary input. The 44 µH inductance and 1.34 kV secondary output are critical for matching CCFL driver requirements. Confirm that the SMD package dimensions fit the PCB footprint and that the dual primary winding aligns with the circuit topology. Consider alternative components if new production is required due to obsolescence.

Part Context

The CTX210605TR-R belongs to the CCFL transformer family, optimized for fluorescent lamp backlighting. It shares the same core specifications as the non-tape variant CTX210605-R, differing only in packaging format. The TR suffix indicates tape and reel delivery, facilitating high-volume surface mount manufacturing processes compared to bulk or individual tray packaging.
