PA1297NL

Overview

The PA1297NL is a flyback transformer manufactured by Pulse Electronics, designed for Switch Mode Power Supplies. It features an inductance of 380 uH and an isolation voltage of 3000 Vrms. The component operates within a temperature range of -40°C to +130°C. Physical dimensions include a length of 27.94 mm, width of 29.21 mm, and maximum height of 20.82 mm. It utilizes through-hole mounting technology.

Feature Summary

• Engineered as a high-performance flyback transformer for power conversion applications
• Provides robust electrical isolation with a 3000 Vrms rating
• Supports wide operating temperatures from -40°C to +130°C

Applications

• Switch Mode Power Supplies (SMPS)
• Flyback converter circuits
• High-frequency power transformation

Procurement Notes

Verify the specific datasheet version and RoHS compliance status before integration, as lifecycle information may vary across distributors. Confirm mechanical footprint compatibility with PCB designs due to through-hole requirements. Check for any product change notifications or end-of-life notices that might affect long-term supply chain stability.

Selection Notes

Select this component when designing flyback topologies requiring 380 uH primary inductance and high isolation voltage. Ensure the thermal management system supports operation up to +130°C. Validate that the physical size fits the enclosure constraints. Compare against other Pulse transformers if different inductance values or package types are needed.

Part Context

This part belongs to the Pulse Electronics transformer portfolio, specifically targeting SMPS applications. It is distinct from surface-mount gate drive transformers like the PA0297 or power inductors such as the PA2247 series. The PA1297NL serves as a discrete magnetic component for energy storage and isolation in AC-DC or DC-DC conversion stages.

Replacement Considerations
