PA0751NL

Overview

The PA0751NL is a surface-mount flyback transformer manufactured by Pulse Electronics, designed for board mounting applications. It features an EFD20-SMD core configuration with 12 pins and utilizes Non-Pb (NPB) construction. The component provides an inductance of 110 µH and supports a primary voltage range of 4 to 80 V alongside a secondary voltage of 3.3 V. It operates within a specified temperature range suitable for standard electronic environments.

Feature Summary

• Utilizes EFD20-SMD core geometry for compact surface-mount integration
• Features 12-pin configuration for standardized board layout
• Constructed with Non-Pb materials compliant with environmental standards

Applications

• Flyback power supply circuits
• Board-mounted power conversion systems
• Electronic devices requiring isolated DC-DC transformation

Procurement Notes

Verify the specific datasheet version and RoHS compliance details directly with the manufacturer or authorized distributor before procurement. Confirm that the NPB material specification meets your project's environmental requirements. Ensure the 12-pin footprint matches your PCB design constraints. Cross-reference the electrical parameters against your system's voltage and inductance needs to guarantee compatibility.

Selection Notes

Select this component when a flyback topology with an EFD20-SMD core is required. The 110 µH inductance and 12-pin SMD package define its physical and electrical integration. Verify that the 4-80 V primary and 3.3 V secondary ratings align with your circuit design. Consider the operating temperature limits and Non-Pb construction for regulatory compliance.
