CTX210655-R

Overview

The CTX210655-R is a discontinued surface-mount CCFL transformer manufactured by Eaton Electronics. It features a dual primary winding and a single secondary winding configuration, designed for board-mounted applications. The component has a power rating of 2.5 VA, with a primary voltage rating of 20 V and a secondary voltage rating of 1.34 kV. Its physical dimensions are 26 mm in length, 16.5 mm in width, and 7.1 mm in height.

Feature Summary

• Dual primary winding architecture for flexible input integration
• Single secondary winding output structure
• Surface-mount device (SMD/SMT) mounting style

Applications

• Cold Cathode Fluorescent Lamp (CCFL) backlighting systems
• Electronic display panel illumination circuits
• Specialty transformer applications requiring high secondary voltage

Procurement Notes

This component is officially discontinued and no longer manufactured by Eaton Electronics. Availability is limited to existing stock from third-party distributors or surplus channels. Verification of part authenticity and storage conditions is critical when sourcing obsolete inventory. Direct procurement from the manufacturer is not possible. Buyers should confirm lead times and return policies carefully due to the non-standard supply chain status of this end-of-life product.

Selection Notes

Designers must consider the discontinuation status when selecting this transformer for new products. Alternative components within the same Eaton CCFL series or comparable specialty transformers should be evaluated for long-term supply stability. The specific electrical parameters, including the 1.34 kV secondary output and 2.5 VA rating, dictate its suitability for particular lighting loads. Space constraints defined by the 26x16.5x7.1 mm footprint must align with the target PCB layout requirements.

Part Context

The CTX210655-R belongs to the CCFL transformer family produced by Eaton Electronics' division. This series was engineered for specialized lighting applications requiring isolated high-voltage generation. The part number suffix typically denotes specific electrical characteristics within the broader product line. As an SMD component, it facilitated automated assembly processes for compact electronic devices during its active production lifecycle.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The CTX210652-R, CTX210657-R, and CTX210659-R are listed in related datasheets but their electrical compatibility requires independent verification against specific design requirements.
