PH9400.566NLT

Overview

The PH9400.566NLT is a surface-mount isolation transformer from Pulse Electronics, designed for high-voltage gate drive applications. It features an inductance of 4.5 mH and a turns ratio of 5:6:6. The component supports an isolation voltage of 600 VDC (or 4kVrms per some sources) and operates within a temperature range of -40°C to +125°C. Physical dimensions are 16.70mm x 12.70mm with a maximum height of 14.20mm. It utilizes SMD/SMT termination and is available in reel or cut tape packaging.

Feature Summary

• High isolation capability suitable for demanding power electronics environments
• Optimized for gate drive signal transmission with specific turns ratios
• Robust thermal performance across extended industrial temperature ranges

Applications

• Gate drive circuits for power semiconductors
• Isolated signal transmission in power converters
• High-voltage interface modules

Procurement Notes

Verify the specific isolation rating required by your design, as documentation references both 600V and higher RMS values. Confirm package availability in reels or cut tapes. Ensure the PCB footprint matches the 16.70mm x 12.70mm dimensions. Check RoHS compliance status before finalizing procurement orders.

Selection Notes

Select this component when high isolation voltage and precise turns ratios are critical for gate drive integrity. Consider the 4.5 mH inductance for low-frequency signal fidelity. Evaluate the 14.20mm height constraint against board space limitations. Compare against other PH9400 series variants if different ratios or inductances are needed.

Part Context

This part belongs to the PH9400 series of high-isolation transformers from Pulse Electronics. The series includes variants like PH9400.122NLT with different turns ratios and inductances. These components are engineered for surface-mount assembly in compact power electronic designs requiring reliable galvanic isolation.

Replacement Considerations

Direct substitutes include other PH9400 series parts such as PH9400.122NLT, provided the turns ratio and inductance requirements match the application. Verify pinout compatibility and physical dimensions before swapping.
