Overview
The CTX01-18939-R is a board-mount power transformer manufactured by Eaton Electronics, specifically designed as a flyback transformer. It features an EE16 horizontal core configuration with through-hole technology (THT) mounting and utilizes a 10-pin interface. The component has a primary inductance of 2.5mH and weighs approximately 9.111 grams. This part belongs to the CTX01 series and is classified under power transformers for electronic applications.
Feature Summary
- Utilizes EE16 horizontal core geometry for compact board integration
- Supports through-hole mounting via a 10-pin terminal configuration
- Engineered for flyback converter topologies within power supply circuits
Applications
- Flyback power supply designs
- Board-mounted isolated DC-DC conversion
- General purpose AC-DC adapter implementations
Procurement Notes
Verify current lifecycle status as the component may be discontinued or subject to production changes. Confirm mechanical dimensions and pinout compatibility with existing PCB footprints before ordering. Check for recent Product Change Notifications (PCN) regarding labeling or packaging updates. Ensure that the 2.5mH inductance specification meets the specific circuit requirements for the intended flyback application.
Selection Notes
Select this transformer when a horizontal EE16 form factor is required for space-constrained designs. The 10-pin THT interface suits manual or wave soldering processes. Consider the 2.5mH inductance value relative to the switching frequency and load requirements. Evaluate thermal performance and isolation ratings against the target application's safety standards.
Part Context
This component is part of the CTX01 series from Eaton Electronics, which focuses on board-mount power transformers. The series offers various configurations for different core sizes and winding options. The CTX01-18939-R specifically addresses needs for horizontal mounting solutions with defined inductance values for standard flyback architectures.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference data with official Eaton distributors or technical support for equivalent components with matching electrical and mechanical specifications.
