Overview
The PA1260NL is a surface-mount power transformer manufactured by Pulse Electronics, designed for high-frequency applications. It features an inductance of 77.4 uH and a maximum DC resistance of 0.25 Ohms. The component operates within a temperature range of -40 C to +130 C and supports a power rating of 13.5W. It utilizes a wire-wound construction suitable for board mounting.
Feature Summary
- Surface mount technology compatible design for automated PCB assembly
- High-frequency wire-wound transformer construction
- Compliant with RoHS environmental standards
Applications
- Switching mode power supply circuits
- High-frequency power conversion systems
- Board-mounted power isolation applications
Procurement Notes
Verify the specific datasheet version and mechanical dimensions against your PCB footprint requirements before ordering. Confirm that the operating temperature range of -40 C to +130 C aligns with your system's thermal profile. Ensure the 13.5W power rating and 77.4 uH inductance meet your circuit design specifications. Check for any recent product change notifications regarding material or manufacturing updates.
Selection Notes
Select this component when a high-frequency, surface-mount power transformer is required for compact designs. The 13.5W rating and 0.25 Ohm resistance define its electrical limits. Consider the +130 C maximum operating temperature for high-thermal environments. Compare against similar models like PA1260NLT if lead frame variations are needed. Verify compatibility with your specific switching frequency and voltage levels.
Part Context
This part belongs to the Pulse Electronics power transformer family, specifically optimized for high-frequency operation. It is distinct from signal transformers like the H1260NLT used in LAN applications. The PA1260NL series focuses on power delivery rather than data transmission, utilizing a robust wire-wound core structure for efficient energy transfer in SMPS topologies.
Replacement Considerations
The PA1260NLT is a related variant within the same product line. Verify if the LT suffix indicates a different packaging format or minor specification adjustment. No other direct substitute part numbers are publicly confirmed in the provided documentation.
